Answer:

1 = -48

2 = 9

3 = -6

4 = - 4

Step-by-step explanation:

Hello there!

For each problem we are going to want to plug in the value of x (which is given) and find the total value of the expression

For #1

8(-4) + 4(-4)

8 * - 4 = -32

4*-4=-16

-32+(-16)=-48

So the answer to #1 is -48

For #2

9(3)-18

9*3=27

27-18=9

so the answer to #2 is 9

For #3

-2(8)+10

-2*8=-16

-16+10=-6

so the answer to #3 is -6

For  #4

5(-3)+11

5*-3=-15

-15+11=-4

So the answer to #4 is -4

Answer:

This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.

She painted 2/5 of the wall.

She still needs to paint 3/5 of the wall.

3 is 50% more than 2, so 3/5 is 1.5 times 2/5, so it will take her 1.5 times the time it took so far.

1.5 * 40 minutes = 60 minutes.

Answer:

Surface area of cylinder = 91.2π cm²

Volume of cylinder = 57.6π cm³

Step-by-step explanation:

Given:

Height of cylinder = 1.6 cm

Radius of cylinder = 6 cm

Find:

Surface area of cylinder

Volume of cylinder

Computation:

Surface area of cylinder = 2πr[h+r]

Surface area of cylinder = 2π(6)[1.6+6]

Surface area of cylinder = 2π(6)(7.6)

Surface area of cylinder = 91.2π cm²

Volume of cylinder = πr²h

Volume of cylinder = π(6)²(1.6)

Volume of cylinder = π(36)(1.6)

Volume of cylinder = 57.6π cm³

The equation of the line is y = 9x. The correct answer is C.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

the points of line are (1,9) and (0,0).

Now,

In this case, the given points are (1, 9) and (0, 0). We can use them to find the slope:

m = (y2 - y1) / (x2 - x1) m = (0 - 9) / (0 - 1) m = -9 / -1 m = 9

Then we can use the point-slope form with any of the given points. Let’s use (0, 0):

y - y1 = m (x - x1) y - 0 = 9 (x - 0) y = 9x

This is already in slope-intercept form. The slope is 9 and the y-intercept is 0.

Therefore, the equation of the line will be y = 9x.

Answer:

w = 238

Step-by-step explanation:

So create a system of equations if the number of m = 2w where the men's number is twice the women's number.  and m + w = 714 so substitute 2w for m

2w + w = 714 so 3w = 714, divide both sides by 3, you get w = 238

Answer:

C 532 square feet

Step-by-step explanation:

We need to calculate the surface area of the storage shed.  This includes the floor.  I did the calculations without the floor and I got 434ft, which is not one of the answers.

Length = 14ft Width = 7ft Height = 8ft

The front and back of the shed both have dimensions of 14x8

The left and right sides of the shed have dimensions of 7x8

The roof and floor have the dimensions of 14x7

2(14 x 8) + 2(7 x 8) + 2(14 x 7)

2(112) + 2(56) + 2(98)

224 + 112 + 196

532 square feet

Answer:

V(x) = 4(1.35)x, and it grows.

Step-by-step explanation:

The statement that illustrates the approximate value of the bond in hundreds of dollars over time in years is:

"The value of the bond can be approximated by the quadratic equation V(x) = 0.725x² + 0.675x + 4.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

We can use the given data points to approximate the relationship between the value of the bond and time by fitting a curve that best fits the points.

Based on the given data,

It seems that the value of the bond is increasing at an accelerating rate over time.

We can try to approximate this relationship by fitting a quadratic equation to the data.

Let's assume that the relationship between the value of the bond and time can be approximated by the quadratic equation:

V(x) = ax² + bx + c

where V(x) is the value of the bond in hundreds of dollars after x years, and a, b, and c are constants to be determined.

To solve for a, b, and c, we can use the three data points for which we have values of V(x):

V(0) = 4, V(1) = 5.4, V(2) = 7.29

Substituting these values into the equation.

a(0)² + b(0) + c = 4

a(1)² + b(1) + c = 5.4

a(2)² + b(2) + c = 7.29

Simplifying.

c = 4

a + b + c = 5.4

4a + 2b + c = 7.29

Substituting c = 4.

a + b = 1.4

4a + 2b = 3.29

Solving for a and b.

a = 0.725

b = 0.675

Now,

The equation that approximates the relationship between the value of the bond and time is:

V(x) = 0.725x² + 0.675x + 4

This equation tells us that the value of the bond is increasing at an accelerating rate over time, starting at $400 (or 4 hundred dollars) and increasing by approximately 0.725 hundred dollars for each year squared, plus 0.675 hundred dollars for each year, plus a constant 4 hundred dollars. For example, after 5 years, the value of the bond would be approximately:

V(5) = 0.725(5)² + 0.675(5) + 4 = 23.75

Therefore,

The statement that illustrates the approximate value of the bond in hundreds of dollars over time in years is:

"The value of the bond can be approximated by the quadratic equation V(x) = 0.725x² + 0.675x + 4.
