Answer:

19, 18, 15.5

Step-by-step explanation:

To solve this problem, you need to substitute the given values into the function.

b(x = -2) = 18 - 0.5(-2) = 18 + 1 = 19

b(x = 0) = 18 - 0.5(0) = 18 - 0 = 18

b(x = 5 ) = 18 - 0.5(5) = 18 - 2.5 = 15.5

$ 1508.57 and please give brainliest

Step-by-step explanation:

The road around the park = 3 m wide,

and the circumference of the park = 132 m,

We have to find the cost of fencing

the outer boundary,

the rate = $10 per m

Step-by-step explanation:

As we know that the circumference

of a circle = 2 × 22÷7 × radius

2 × 22÷7 × radius = 132 m,

44 × radius = 132 m × 7,

44 × radius = 924 m,

radius = 924 ÷ 44 m

So, radius = 21 m ( smaller circle )

radius = 21 m + 3 m ( larger circle )

= 24 m

Usually, we fence on the borders means it's

the circumference of the larger circle

= 2 × 22÷7 × radius

= 44÷7 × 24 m

= 1056÷7 m

= 150.85 m

cost of fencing = $ 10/m

total cost = 150.85 × $ 10

= $ 1508.57

Volume of a cube = l³

                              = (11 in)³

                              = 1331 in³

Surface area of cube = 6a²

                                   = 6 (11 in)²

                                   = 726 in²

Answer:

A*B*C= 28

Step-by-step explanation:

A+B+C=20

1. A = 4(B+C)

2. B = 7C

3. C = C

----------------------

1.

A = 4( 7C + C )

A=4(8C)

A= 32C

---------------------

A+B+C=20

32C + 7C + C = 20

40C = 20

C = 20/40

C = 1/2

------------------------

A= 32(1/2) = 32/2 = 16

B= 7(1/2) = 7/2

C= 1/2

A*B*C = 16 * 7/2 * 1/2

A*B*C=  28

Answer:

22.6

Step-by-step explanation:

102÷4 1/2=22.6

You can double check this by multiplying 22.6 with 4 1/2, which will give you the answer without it being rounded.

Answer:

C

Step-by-step explanation:

it's c because this is a false statement, which means that the original statement is also a false one

so it doesn't have any answer

-9 that is the answer

Answer:

3x - 3 + 5x = 4(2x -3)

collect like terms

3x + 5x - 3 = 8x - 12

8x -3 = 8x - 12

8x -8x = 3 - 12

it's null

the expression is an indefinite one

Answer:

A) 23+x = 35

x = 12

Step-by-step explanation:

The question is asking you to find the equation and variable that best represents the scenario. We know that Emily had 35 dollars and had 7 dollars after paying for everything. This means that 7 plus what she spent must equal 35. However, we only know the cost of the ticket. So, add the cost of the ticket to the money left to figure out part of the equation. This equals 23 dollars. Therefore, whatever is left must be what she spent on lunch. So, the equation should look like 23 + x = 35. This is because the $23 is the ticket/the amount left and the x is the cost of lunch. Together they equal what Emily brought to the fair.

Step-by-step explanation:

Answer:

y=2x^2+4x−16

Step-by-step explanation:

Assume that the equation of the parabola is y=ax2+bx+c.

Since the parabola passes through the point (−4,0), then 0=16a−4b+c.

Since the parabola passes through the point (2,0), then 0=4a+2b+c.

Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:

Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.

The equation of a parabola is  y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).

A parabola can be represented by the equation:

y = ax² + bx + c

To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:

0 = a(-4)² + b(-4) + c

0 = a(2)² + b(2) + c

Solving these equations for a and c gives us:

c = b(-4)

c = -2b

The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:

-10 = a(1)² + b(1) + (-2b)

-10 = a + b - 2b

-10 = a - b

Substituting c = b(-4) into the equation gives us:

y = a x² + b x + b(-4)

Substituting a = -b and solving for b gives us:

y = (-b) x² + b x + b(-4)

y = -b(x² - x - 4)

Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:

y = -(1)(x² - x - 4)

y = -x² + x + 4

Thus, the equation of a parabola is y = -x² + x + 4.

Answer:

B is subset of A

Step-by-step explain

I think in my college

Answer:

D) 22

Step-by-step explanation:

B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.

So that means:

3x - 14 = x + 10

Now solve this equation.

3x - 14 = x + 10

+14. +14

3x = x + 24

-x

2x = 24

/2. /2

X = 12.

Now we know the value of x, insert the value into x + 10.

12 + 10 = 22

The answer is 22

Answer:

B) 12

Step-by-step explanation:

Because,

3x - 14 = x + 10

3x - x = 10 + 14

2x = 24

x = 12
