Answer:

m = 1

b = -4

Step-by-step explanation:

The "slope-intercept form" of the equation for a line is often written ...

y = mx + b

The x-coefficient, m, is the slope of the line. The constant, b, is the y-intercept.

Comparing the slope-intercept form to your equation, we see that ...

m = 1

b = -4

_____

The slope is the ratio of "rise" to "run" for the graph. Here, that means the line goes through the point (0, -4), the y-intercept, and rises 1 unit for each 1 unit to the right of that point. For example, the point (4, 0) will also be on the line. (It is right 4 units and up 4 units from the y-intercept.)

The equation can be graphed by entering it into a graphing tool, or by plotting two points on the line and drawing a line through them.

Answer:

It's actually right and scalene

Step-by-step explanation:

Since there is a ninety degree angle, it isn't obtuse or acute because the angle is a right angle. And since all the side lengths are different, it must be scalene in comparison to isoceles or equilateral.

The given triangle is Right angled triangle and Scalene triangle i.e. option A and E.

Triangle is a two dimensional shape having three side and sum of all angles is equals to .

We have,

A triangle with,

Angles of 90°, 53°, 37° and

Sides 3, 4, 5.

So,

We know that,

When a triangle have any angle equals to 90° then it is a Right angled triangle.

Now,

When a triangle have any three sides unequal and all three angles are of different measures, then it is Scalene triangle.

So,

From the above mentioned statements we can say that triangle is Right angled and Scalene triangle.

Hence, we can say that the given triangle is Right angled triangle, Scalene triangle.

Below is a labeled rectangle:

length = w + 20

we know length is 36 so we plug that in:

36 = w + 20

We need to isolate w and to do that we must subtract 20 from both sides:

(36 - 20) = w + (20 - 20)

16 = w + 0

w = 16

width is 16 feet

Answer:

∠4 = 50°

Step-by-step explanation:

∠1 + ∠5 = 100°, but ∠1 = ∠5 ( corresponding angles ), hence

∠1 = ∠5 = 50°

∠4 = ∠1 = 50° ( vertical angles )

X will equal 8 and y would equal 3

The solution to the system of equations -2x + 9y = 11 and -5x + 2y = -34 is found using the elimination method. The solution is x = 8 and y = 3.

The system of equations provided appears to be:

To solve this system, we can use the method of substitution or elimination. In this case, we'll use the elimination method. First, we want to manipulate the equations so that when we add them together, one of the variables gets eliminated.

Let's multiply the first equation by 5 and the second equation by 2:

Now, we subtract the second equation from the first:

-10x + 45y - (-10x + 4y) = 55 - (-68)

Which simplifies to:

41y = 123

Divide both sides by 41 to find the value of y:

y = 123 / 41 = 3

Now, substitute y = 3 into one of the original equations to solve for x. We'll use the first equation:

-2x + 9(3) = 11

-2x + 27 = 11

-2x = 11 - 27

-2x = -16

Divide both sides by -2:

x = -16 / -2 = 8

The solutions to the system of equations are x = 8 and y = 3.

we called it the rainbow method :)

The answer is A.

-9 • -2x = 18x

-9 • -3 = 27

Therefore, it is 18x+27

Answer:

132860 to nearest whole number.

Step-by-step explanation:

Sum of n terms = a1 .(r^n - 1) / (r - 1).

S25 = 177,147 ((-1/3)^25 - 1) / (-1/3 - 1)

= 177,147 * -1 /    -4/3

= 132860.

The given task involves finding the sum of the first 25 terms of a geometric sequence with a specific first term and common ratio. This is done using the sum formula for a finite geometric sequence, with the terms alternating in sign due to a negative common ratio.

The subject question deals with the concept of a geometric sequence, specifically finding the sum of the first 25 terms. A key formula to solve this question is the sum of a finite geometric sequence: Sₙ = a₁(1 - rⁿ)/(1 - r), where a1 is the first term, r is the common ratio, and n is the number of terms.

In this case, a₁ is 177,147, r is -1/3 and n is 25. Substituting these values into the formula, the sum, S25 = 177,147 × (1 - (-1/3)25) / (1 - -1/3).

By solving this equation, we get the sum of the first 25 terms of the given geometric sequence. Note that due to the negative common ratio, the terms alternate in sign in this particular geometric sequence.

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = - 3, hence

[tex]a_{n}[/tex] = 10 - 3(n - 1) = 10 - 3n + 3 = - 3n + 13, so

Answer:

The percent increase of the population of chipmunks was 29%

Step-by-step explanation:

we know that

The population of 300,000 chipmunks represent the 100%

The increase of population is equal to

(387,000-300,000)=87,000 chipmunks

Using proportion find the percent increase

Let

x-----> the percent increase

300,000/100%=87,000/x

x=100*87,000/300,000

x=29%

12-5x= 7x+3

12-7x-5x= 7x-7x+3

12-12x= 3

12-12-12x= 3-12

-12x= -9

Divide by -12 for -12x and -9

-12x/-12= -9/-12

x= 9/12

Divide by 3 for 9/12

x= 3/4

Answer is x= 3/4

Step-by-step explanation:

12 - 5x = 7x + 3

Add 5x on the both sides so there would only be 12 on the right side.

So...... 12 = 12x + 3

The formula for area of a circle π[tex]r^{2}[/tex]. This means that we can find the radius from the circle's circumference and use it to find the area.

First we have to equal 14 to 2πr because both are representations of circumference and we need to find r.

x(100-15x) when x = 5.

Answer:

Step By Step Explanation:

You'll need to substitute (that word is hard, it means replace though) the x, and get a proper equation (because they already gave you the x).

Look at how ugly and hard this is: x(100-15x) When x = 5.

Now it's better when replacing the x: 5(100-15×5)

Put it in a calculator if you wanted to avoid step by step work, but I'll show you how to do it step by step if you wanted.

5(100-15×5)

(5)×(100)+(5)(-75)

500-375

=125.

So, write this for your answer:

x(100-15x) = 125 Because 5(100-15×5)=125. And x = 5.

The volume of the pill is [tex]V=452\ mm^{3}[/tex]

Step-by-step explanation:

Find the volume of the pill in cubic millimeters

we know that

The volume of the pill is equal to the volume of the cylinder plus the volume of a sphere (two hemisphere is equal to one sphere)

so

we have

[tex]V=\frac{4}{3}\pi r^{3}+\pi r^{2}h[/tex]

[tex]r= (18-12)/2=3\ mm\\ h=12\ mm[/tex]

assume

[tex]\pi =3.14[/tex]

substitute

[tex]V=\frac{4}{3}(3.14)(3)^{3}+(3.14)(3)^{2}(12)\\V=452\ mm^{3}[/tex]

Volume is a three-dimensional scalar quantity. The volume of the pill is 452.3893mm³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The height of the cylindrical portion is 12mm and the overall height is 18mm. Therefore, the radius of the hemisphere at any one end will be half the difference between the cylindrical portion and the overall height. Thus,

The radius of the sphere, R = (18mm - 12mm)/2 = 3mm

The volume of the capsule

= Volume of cylinder +2(Volume of the hemisphere)

= (πR²h) + 2[(4/6)πR³]

= (π×3²×12) + 2[(4/6)×π×3³]

= 339.292mm³ + 113.0973mm³

= 452.3893 mm³

Hence, the volume of the pill is 452.3893mm³.

Answer:

a) i) No

ii) Probability of drawing a diamond and then spade without replacement is 0.0637.

b) i) Yes

ii) Probability of drawing a diamond and then spade with replacement is 0.0625

Step-by-step explanation:

Part a) Without replacement:

i) Are these events independent?

No, because the both events are dependent. because a card taken out of the deck is not replaced back before taking out the other card so the chances of event occur change.

ii) Determine the probability of drawing a diamond and then a spade without replacement.

Probability of drawing a diamond and then spade = (Probability of drawing a diamond) * (Probability of drawing a spade)

Probability of drawing a diamond :

Total cards in deck = 52

Diamonds = 13

Probability of drawing a diamond  = 13/52

Probability of drawing a spade:

Total cards in deck after taking diamond = 52 -1 =51

Spades = 13

Probability of drawing a spade  = 13/51

Probability of drawing a diamond and then spade = 13/52 * 13/51

= 169/2652

=0.0637

So, Probability of drawing a diamond and then spade without replacement  is 0.0637

Part b) With replacements

i) Are these events independent?

Input Yes or No:

Yes, these events are independent because a card taken out of the deck is replaced back before taking out the other card so the chances of event occur doesn't change.

ii) Determine the probability of drawing a diamond and then a spade with replacement.

Probability of drawing a diamond and then spade = (Probability of drawing a diamond) * (Probability of drawing a spade)

Probability of drawing a diamond :

Total cards in deck = 52

Diamonds = 13

Probability of drawing a diamond  = 13/52

Probability of drawing a spade:

Total cards in deck after replacing diamond = 52

Spades = 13

Probability of drawing a spade  = 13/52

Probability of drawing a diamond and then spade = 13/52 * 13/52

= 169/2704

=0.0625

So, Probability of drawing a diamond and then spade with replacement is 0.0625

The first two events are not independent, with a probability P = 0.0637

The second pair of events is independent, and the probability is P = 0.0625

First, all the cards on the deck have the same probability of being randomly drawn, which will be p = 1/52.

A) Now, if Lacy first draws a diamond card, now the number of cards in the deck are less (now there are 51 cards on the deck). So the probability of drawing now a spade is larger than before. Then the first two events are not independent.

The probability of drawing a diamond card at first is:

P = 13/52 (because there are 13 diamonds and a total of 52 cards).

The probability of drawing a spade after is:

Q = (13/51)

The joint probability is the product of the individual probabilities, this will give:p = P*Q = (13/52)*(13/51) = 0.0637

B) Now we replace the first card, then the events are now independent, as the probability of drawing a spade after the first draw is not changed (because the total number of cards will be 52).

The probability of drawing a diamond is:

P = 13/52

Now we replace the diamond card drawn.

The probability of drawing a spade will be:

Q = 13/52

The joint probability is:

p = P*Q = (13/52)^2 = 0.0625
