Answer:

f(x) = -60 is your answer

Step-by-step explanation:

Plug in 3 for x

f(x) = 5x² - 7(4x + 3)

f(x) = 5(3²) - 7(4(3) + 3)

Follow PEMDAS. First, solve the parenthesis

3² = 9

4(3) + 3 = 12 + 3 = 15

f(x) = 5(9) - 7(15)

Multiply

f(x) = 45 - 105

Simplify. Subtract

f(x) = 45 - 105

f(x) = -60

f(x) = -60 is your answer

~

The value of f(3) in the function f(x) = 5x² - 7(4x+3) is -60.

To find the value of f(3), we need to substitute x = 3 into the given function f(x) = 5x² - 7(4x+3). First, let's simplify the expression inside the parentheses: f(x) = 5x² - 28x - 21. Now substitute x = 3: f(3) = 5(3)² - 28(3) - 21. Simplifying further, we get: f(3) = 45 - 84 - 21 = -60.

To find the value of f(3) for the given function f(x) = 5x² - 7(4x+3), we need to substitute 3 in place of x:

Answer: x = 7.2

=============================

Explanation:

As shown in the diagram (see attached image below), the red interior angles are

180-10x

180-15x

180-20x

180-5x

Each of those expressions is in the form 180-E, with E as the exterior angle. Add up the interior angles. Set the sum equal to 360 and solve for x. For any quadrilateral, the four interior angles always add to 360.

(angle1)+(angle2)+(angle3)+(angle4) = 360

(180-10x) + (180-15x) + (180-20x) + (180-5x) = 360

(180+180+180+180)+(-10x-15x-20x-5x) = 360

720-50x = 360

-50x = 360-720

-50x = -360

x = -360/(-50)

x = 36/5

x = 7.2

Answer:

The value of y is 6.

Step-by-step explanation:

To find the value of y, start by using the known information we have in the equation for slope. The equation is below.

m(slope) = (y2 - y1)/(x2 - x1)

In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.

1/2 = (7 - y)/(2 - 0)

1/2 = (7 - y)/2

Now we can use cross multiplication to solve for y.

1/2 = (7 - y)/2

1*2 = 2(7 - y)

2 = 14 - 2y

-12 = -2y

6 = y

Answer:

x=9, y=-4

C (9,-4)

Step-by-step explanation:

−4y − 3x = −11

x − 2y = 17

WE are using substitution, so solve the second equation for x

Add 2y to each side

x -2y+2y = 17+2y

x = 17+2y

Substitute this into the first equation

-4y -3x = -11

-4y -3(17+2y) = -11

Distribute the 3

-4y -3*17 -3*2y = -11

-4y -51 -6y = -11

Combine like terms

-10y-51=-11

Add 51 to each side

-10y-51+51=-11+51

-10y = 40

Divide by -10

-10y/-10 = 40/-10

y = -4

Now we need to find x

x= 17+2y

x = 17+ 2(-4)

x =17-8

x=9

By solving the second equation for x, substituting into the first equation, and simplifying, we find the solution to the system is (9, -4), which corresponds to Option C.

In order to find the solution of the system using substitution, we first solve one of the equations for x or y. Looking at the second equation x - 2y = 17, we can solve for x to get x = 2y + 17. Now we substitute this expression for x into the first equation - 4y - 3x = - 11, which gives us:

- 4y - 3(2y + 17) = - 11

Simplifying this equation, we obtain:

- 4y - 6y - 51 = - 11

Combine like terms:

- 10y - 51 = - 11

Add 51 to both sides:

- 10y = 40

Now, divide both sides by - 10 to find y:

y = - 4

After obtaining the value for y, we substitute it back into the equation we derived for x (x = 2y + 17):

x = 2( - 4) + 17

Which simplifies to:

x = - 8 + 17

Finally, we get x = 9.

The solution for the system is therefore (9, - 4), which corresponds to Option C.

Jay has run two-thirds of 6 miles, that is, 4 miles. When converted to yards, it is approximately 7040 yards.

To find out how far Jay has run to the nearest yard, we first need to find out 2/3 of 6 miles since Jay has run this fraction of the distance. You can calculate two-thirds of a total by multiplying the total by 2/3. So, Jay has run 2/3 * 6 miles, which equals 4 miles.

Since we want to find out how far he has run in yards, we need to convert these miles to yards. We know that 1 mile is approximately 1760 yards. Hence, Jay has run approximately 4 * 1760 = 7040 yards.

Step-by-step explanation:

If you lose cash and someone finds it, you've lost it without recourse. If you lose a credit card, usually the issuer of the card can cancel it after your last verified purchase and replace the card for you. That is the main advantage.

You also have a record of what you've spent with a credit card. Sometimes you get a receipt and some sometimes you don't when you use cash.

Cash forces you to carry around coins, especially if you make a lot of small purchases in different places. Getting change for 2.22 cents from a 20 can be a little awkward and soon the big bills turn into many more little ones. Credit cards don't have that disadvantage.

Answer:

There are online services that will help someone monitor their credit and make a note of any changes in their credit score. Credit card monitoring keeps track of all open accounts and monitors hard inquiries. That way, if someone did not make the purchase, they can immediately tell the lender that the card has been compromised.

two real different roots

Step-by-step explanation:

Consider polynomial function

[tex]M(x)=-4x^2+x+1.[/tex]

The discriminant is

[tex]D=b^2-4ac=1^2-4\cdot (-4)\cdot 1=1+16=17.[/tex]

Since [tex]D>0,[/tex] the polynomial function [tex]M(x)[/tex] has two real different roots.

Answer:

1. (h + p)(x) = 2x^2 - 11x + 16

2. It is the same problem as #1.

3. (k - f)(x) = 5x^3 + x^2 - 17x + 2

4. (q - g)(x) = 4x^2 + 7x - 14

Step-by-step explanation:

We are given that the values of h(x) = 2x^2 - 5x + 15 and p(x) = -6x + 1. Using these values you can substitute them into (h + p)(x).

(2x^2 - 5x + 15) + (-6x + 1)

Start by combining like terms. -5x and -6x will combine; 15 and 1 will also combine. 2x^2 will stay the same since there is no other term for it to combine with.

2x^2 - 11x + 16

Combine like terms. We will be adding since h(x) and p(x) are being added together.

We are given that k(x) = 8x^3 - 12x + 2 and f(x) = 3x^3 - x^2 + 5x. Knowing these values we can substitute k(x) and f(x) into (k - f)(x). This will look like:

(8x^3 - 12x + 2) - (3x^3 - x^2 + 5x)

Start by combining like terms. The terms to the same power can be combined (keep in mind we are finding the difference, in other words: subtracting). The terms with "x" can be combined as well. After doing so, your evaluated expression will look like:

5x^3 + x^2 - 17x + 2

q(x) = 4x^2 + 9x - 10 and g(x) = 2x + 4. Substitute q(x) and g(x) into (q - g)(x).

(4x^2 + 9x - 10) - (2x + 4)

Use the same rules I said above. The simplified expression will look like:

4x^2 + 7x - 14

If we start from the origin, then the vector would be v = (52, 12) as given. But suppose we shift its initial point. Doing so would preserve its direction. For example, if we move its initial point to (1, 1), we'd have to shift its terminus by the same amount (1 unit to the right, 1 unit up) so that its terminal point would be (52 + 1, 12 + 1) = (53, 13).

Option A is not correct. If we want the vector to start at (52, 12), we have to adjust the terminus by the same distance by adding (52, 12) to the terminus. This means the resulting vector would start at (52, 12) and end at (52 + 52, 12 + 12) = (104, 24).

One important thing to observe here is that the difference between the terminal and initial points always returns v. In the first example: (53, 13) - (1, 1) = (52, 12). In checking option A: (104, 24) - (52, 12) = (52, 12). So to eliminate any other answer choices, all you need to do is subtract.

Option B is correct by this "rule". (66, 7) - (14, -5) = (52, 12).

Options C and D are not. (0, 12) - (52, 0) = (-52, 12), and (64, -4) - (-12, 16) = (76, -20).

Final answer:

The initial and terminal points that correctly represent the vector v = (52, 12) in component form are option B: initial (14, -5); terminal (66, 7), as these points give the same components when subtracted (terminal - initial).

Explanation:

The student is asking about the initial and terminal points for a vector given in component form. The vector v is (52, 12), which means it has an x-component of 52 and a y-component of 12. This can be visually represented as a directed line segment with an initial point and a terminal point. The correct initial and terminal points for vector v would result in the same component form when subtracting the coordinates of the initial point from the coordinates of the terminal point (terminal - initial).

Option B has the initial point (14, -5) and terminal point (66, 7). By calculating the difference between the terminal and initial points: (66 - 14, 7 - (-5)) = (52, 12), we can see that these points correctly represent the vector v in component form. Therefore, the answer is B.

(3 1/2, 7 1/4)

Step-by-step explanation:

A 1:3 ratio means we want 4 equal parts  (1+3 = 4)

Find the distance of the segment and divide by 4

(x2+x1)/4,  (y2+y1)/4

(8-2)/4 , (5-8)/4

6/4, -3/4

Since the first part is of ratio 1, we multiply by 1

Now add this to the starting point

(2 + 6/4, 8+ -3/4)

Getting a common denominator of 4

2*4/4 = 8/4

8 *4/4 = -3/4

To find the probability that the car will travel a maximum distance between 125 and 135 miles, we need to calculate the z-scores for these distances and find the corresponding probabilities using a standard normal distribution table or calculator.

To find the probability that the car will travel a maximum distance between 125 and 135 miles, we need to calculate the z-scores for these distances using the formula: z = (x - mean) / standard deviation.

For 125 miles: z = (125 - 134) / 4.8 = -1.875.

For 135 miles: z = (135 - 134) / 4.8 = 0.208.

Next, we need to find the corresponding probabilities for these z-scores using a standard normal distribution table or calculator. The probability of a z-score less than -1.875 is approximately 0.0301, and the probability of a z-score less than 0.208 is approximately 0.5829.

To find the probability between 125 and 135 miles, we subtract the probability of a z-score less than 125 from the probability of a z-score less than 135: 0.5829 - 0.0301 = 0.5528.

Therefore, the probability that the car will travel a maximum distance between 125 and 135 miles is approximately 0.5528 or 55.28%.

Answer: y = 0.4

Step-by-step explanation: Using the distributive property, first by distributing the numbers outside the bracket to the ones inside.

( - 3 * 2 ) (- 3 *-0.4y) +5.6 = (0.4*3y) (0.4*1)

   - 6     +       1.2y  +   5.6  =  1.2y  +   0.4

Next step is to collect like terms :

(- 6 + 5.6) +1.2y  =  1.2y +0.4

- 0.4 +1.2y =1.2y +0.4

Next step is to get rid of of the 0.4 :

- 0.4 +1.2y =1.2y +0.4

+0.4                     +0.4

= 1.2y=1.2y+0.4

=1.2y-1.2y=0.4

y=0.4.

Check the value of the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then roots are real

• If b² - 4ac = 0 roots are real and equal

• If b² - 4ac < 0 then roots are not real

given (x - a)(x - b) = k² ( expand factors )

x² - bx - ax - k² = 0 ( in standard form )

x² + x(- a - b) - k² = 0

with a = 1, b = (- a - b), c = -k²

b² - 4ac = (- a - b)² + 4k²

For a, b, k ∈ R then (- a - b)² ≥ 0 and 4k² ≥ 0

Hence roots of the equation are always real for a, b, k ∈ R
