Answer:

The difference between value of y at x=11 is 385, the correct option is third.

Step-by-step explanation:

The difference between value of y at x=11 is 385, the correct option is third.

The equation of a line which passing through two points is given below,

The two points from the table are (3,240) and (4,320), the equation is,

Put x=11

Therefore according to the table the value of y is 880 at x=11.

The two points from the table are (2,90) and (4,180), the equation is,

Put x=11,

Therefore according to the table the value of y is 495 at x=11.

The difference between the values of y at x=11 is,

Therefore third option is correct.

Answer

the area of the entire rocket is  44

area of the triangle=6

area of the rectangle=30

area of the trapezoid=8

Step-by-step explanation:

triangle= bxh/2 so 4x3= 12/2= 6

rectangle= bxh so 3x10=30

trapizoid= A=a+b2h so 3+5= 8/2= 4x2= 8

6+30+8=44

Answer:

Part A: x=3 y=75

explain part B a little more

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Step-by-step explanation:

What do we know?

[tex]\frac{2.5}{x} =\frac{10}{12}[/tex]

[tex]\frac{2.5}{x} is \: a \: simplified \: fraction \: of \: \frac{10}{12}.[/tex]

Divide 10/12 by 4:

[tex]\frac{10\div4}{12 \div 4} =\frac{2.5}{3}[/tex]

Substitute into the equation:

[tex]\frac{2.5}{x} =\frac{2.5}{3}[/tex]

x = 3.

Answer:

1st is 30 and 16. 2nd is reduction. 3rd is scale factor of 2/3

Step-by-step explanation:

#1 you dilate by a scale factor of 2 so you just multiply all the sides by 2 to get your answer. 15x2=30 and 8x2= 16.

#2 it is a reduction because m', s', and v' are smaller then m, s, and v

#3 the scale factor is 2/3 because you do the image over the pre-image so -2,2 / -3,3 is 2/3 same is 4,2 / 6,3 and 2,-2 / 3, -3

Step-by-step explanation:

im not positive on number 6

(6y-2y+5y)9

= 54y-18y+45y

80-10y

=10(8-y)

Answer:

45y-18y+54y & 10(8-y)

Step-by-step explanation:

For the first problem, you need to distribute the 9 to the 5y, -2y, and the 6y

If you do this and multiply the 9 by each of the terms you get:

45y-18y+54y

Now we can work on the second problem

When factoring, we have to find a common factor.

In this expression, the common factor is 10 because both 80 and 10 are divisible by 10!

So we but the 10 on the outside of the parentheses and divide 80 and 10 by 10 which gets us an answer of:

10(8-y)

If you were to distribute this, you would get 80-10y so we know it is correct

Hope this helps, have a great day, and please award brainliest!

Answer:

A

Step-by-step explanation:

I think it would be A

Answer:

Ok, so where are the questions at so I can answer them?

Step-by-step explanation:

13 - No

7 - No

74 - No

10 - Yes

u + 32 = 42

u + 32 - 32 = 42 - 32

u = 10

The left side 42  is equal to the right side 42, which means that the given statement is always true

Answer:

1.66

Step-by-step explanation:

Make it and improper fraction: -10/3

put this over a fraction

-10/3

-1/2

It has to be positive because on two negatives

Make them have the same denominators

-20/6

-3/6

Then divide

You get 1.66

Answer:

-10/3 = -1/2g

Disagree. Actual answer:

Step-by-step explanation:

The answer to the question is in the image below. If you want to subtract mixed numbers with unlike denominators, you need to check the greatest common denominator between all of them.

Answer:

False

Step-by-step explanation:

Absolute value is not just flipping to the opposite sign. Absolute value is a distance, so it is always positive.
