To represent the expression -8 + 5 on a number line, start at -8 and move 5 units to the right, ending at -3.

To represent the expression -8 + 5 on a number line, we start at -8 and move 5 units to the right. Since we are adding a positive number, the arrow on the number line will point to the right.

So the number line that represents the expression -8 + 5 would start at -8 and have an arrow pointing to the right, ending at -3.

Answer:

[tex]x^{2}+y^{2} +4x-2y+1=0[/tex]

Step-by-step explanation:

we know that

The general form of the equation of a circle is

[tex]x^{2} +y^{2}+ Dx + Ey + F=0[/tex]

where D, E, F are constants

step 1

Find the radius of the circle

Remember that the distance from the center to any point on the circle is equal to the radius

so

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

[tex](-2,1)\\(-4,1)[/tex]  

substitute the values

[tex]r=\sqrt{(1-1)^{2}+(-4+2)^{2}}[/tex]

[tex]r=\sqrt{(0)^{2}+(-2)^{2}}[/tex]

[tex]r=2\ units[/tex]

step 2

Find the equation of the circle in standard form

[tex](x-h)^{2} +(y-k)^{2}=r^{2}[/tex]

In this problem we have

center ( -2,1)

radius r=2 units

substitute

[tex](x+2)^{2} +(y-1)^{2}=2^{2}[/tex]

[tex](x+2)^{2} +(y-1)^{2}=4[/tex]

Step 3

Convert to general form

[tex](x+2)^{2} +(y-1)^{2}=4\\ \\x^{2}+4x+4+y^{2}-2y+1=4\\ \\x^{2}+y^{2} +4x-2y+1=0[/tex]

Answer:

Step-by-step explanation:

Wages earned by daniel in one hour = $8

Number of working hours spend by daniel in each week = 35

Wages earned by daniel in each week without pay increase = [tex]35\times 8 = 280[/tex]

Increase in pay per week = [tex]\frac{5}{100} \times 280= 14[/tex]

Therefore extra wages earned by Daniel will be $14.

Answer:

• discriminant: 73

• # of real solutions: 2

Step-by-step explanation:

Comparing the equation ...

2x^2 -9x +1 = 0

to the generic form ...

ax^2 +bx +c = 0

we find the coefficient values to be ...

a = 2; b = -9; c = 1

That makes the value of the discriminant, (b^2 -4ac), be ...

(-9)^2 -4(2)(1) = 81 -8 = 73

Since the discriminant is positive, the number of real solutions is 2.

Answer:

300cm

Step-by-step explanation:

First you get the length, width, and height. The length is 15, the width is 12, and the height is 10.

15*12=180

Since their is 2 you multiply by 2

180*2=360

12*10=120

Since their is 2 you multiply by 2

120*2=240

Then you divide by 2 since it is a triangle but before that you add the products up

360+240=600

600/2=300

The three methods are graphing, substitution and elimination.

In my opinion they are all easy but if I had to choose one it would be graphing because when I did homework assignments for this I always took the longest graphing than just solving the systems using substitution or elimination

Among the given options, only ((-196)^(1/4)) is equivalent to a real number, as it involves the fourth root of a negative number, which results in a real value.

The correct answer is option B.

To determine which expression is equivalent to a real number, we need to consider the roots involved and whether they result in a real value.

Let's analyze each option:

A. (-1503)^(1/6): The expression involves the sixth root of a negative number. Odd roots of negative numbers are real, but even roots are not. Therefore, this expression is not guaranteed to be real.

B. (-196)^(1/4): The expression involves the fourth root of a negative number. Similar to option A, the fourth root of a negative number is real, so this expression is valid.

C. (-144)^(1/2): This expression involves the square root of a negative number. Square roots of negative numbers are not real; hence, this expression is not equivalent to a real number.

D. (-1024)^(1/2): The expression involves the square root of a negative number as well. Like option C, this expression is not equivalent to a real number.

In summary, option B ((-196)^(1/4)) is equivalent to a real number because it involves the fourth root of a negative number, and odd roots of negative numbers are real.

Answer:

1,-3,-5

Step-by-step explanation:

Given:

f(x)=x^3+7x^2+7x-15

Finding all the possible rational zeros of f(x)

p= ±1,±3,±5,±15 (factors of coefficient of last term)

q=±1(factors of coefficient of leading term)

p/q=±1,±3,±5,±15

Now finding the rational zeros using rational root theorem

f(p/q)

f(1)=1+7+7-15

   =0

f(-1)= -1 +7-7-15

     = -16

f(3)=27+7(9)+21-15

    =96

f(-3)= (-3)^3+7(-3)^2+7(-3)-15

     = 0

f(5)=5^3+7(5)^2+7(5)-15

    =320

f(-5)=(-5)^3+7(-5)^2+7(-5)-15

      =0    

f(15)=(15)^3+7(15)^2+7(15)-15

     =5040

f(-15)=(-15)^3+7(-15)^2+7(-15)-15

      =-1920

Hence the rational roots are 1,-3,-5 !

Answer:

Actual rational zeros of f(x) are x=-5, x=-3, and x=1.

Step-by-step explanation:

Given function is [tex]f(x)=x^3+7x^2+7x-15[/tex].

constant term = p = -15

coefficient of leading term q= 1

then possible rational roots of given function f(x) are the divisors of [tex]\pm \frac{p}{q}=\pm 1, \quad \pm 3, \quad \pm 5, \quad \pm 15[/tex]

Now we can plug those possible roots into given function to see which one of them gives output 0.

test for x=1

[tex]f(x)=x^3+7x^2+7x-15[/tex]

[tex]f(1)=1^3+7(1)^2+7(1)-15[/tex]

[tex]f(1)=1+7+7-15[/tex]

[tex]f(1)=0[/tex]

Hence x=1 is the actual rational zero.

Similarly testing other roots, we get final answer as:

Actual rational zeros of f(x) are x=-5, x=-3, and x=1.

Step-by-step explanation:

Answer:

The entry has an area of __44___ square feet

The total area of the tree house is __345__ square feet

Step-by-step explanation:

Let's first calculate the area of the trapezoid entrance:

The area of a trapezoid is given by:

A =((b1 + b2) * h) / 2

Where b1 and b2 are the bases or parallel sides.  So, we have:

A = ((6 + 16) * 4) / 2 = (22 * 4) / 2 = 44 sq ft

Now, let's look at the other areas... which are all rectangles, so easy to calculate (b * h).

Playroom: 16 x 14 = 224 sq ft

Side Deck: 3 x 14 = 42 sq ft

Back Porch: 6 x6 = 35 sq ft

So, in the total area of the tree house is:

TA = 44 + 224 + 42 + 35 = 345 sq ft

Answer:

The entry terrace has an area of

48

square feet. The total area of the tree house including the entrance, porch, and side deck is

Equation of line whose slope is 3 and passing point (2, 5) is y = 3x - 1.

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Here, Slope of line = 3

          Passing point (2, 5)

Equation of line

          (y - y₁) = m (x - x₁)

          y - 5 = 3 (x - 2)

          y - 5 = 3x - 6

          y = 3x - 6 + 5

          y = 3x - 1

Final answer:

The value 0.9 represents the 90% of the original price a customer pays after applying a 10% discount. It is used to calculate the discounted price by multiplying the original price by 0.9.

Explanation:

In the context of this question, 0.9 (or 0.90) represents the remainder of the original price G after a 10% discount is applied. When Ray uses his coupon for 10% off the price of ginger roots, this discount factors out 10% of the cost, leaving him to pay just 90% of the original price. This is why the price he pays can be represented as 0.9G, which is the same as saying 90% of G.

The 0.9 is a decimal representation of the percentage that remains after the discount. So, if the original price G is, for example, $10.00, with a 10% discount Ray would be saving $1.00, and thereby paying 90% of the original price, or $9.00. So, 0.9 in this calculation effectively means 90% of the original price.

Representing changes in price using decimals and percentages is a common method in mathematics to describe percentage change or discounts succinctly.
