9514 1404 393

Answer:

  18

Step-by-step explanation:

Solve the first for a, then substitute into the second.

  a = 27/(5b^2)

Then ...

  (27/(5b^2))^2·b = 135

  27^2/(5^2·135) = b^3 = 27/125

  b = ∛(27/125) = 3/5

  a = 27/(5(3/5)^2) = 15

__

The expression of interest is ...

  a +5b = 15 + 5(3/5) = 15 +3

  a +5b = 18

We start by subtracting the deposit,

That would be;

PLEASE HELP 20 POINTS
Step2247 [10]

Answer:

x = 20

Step-by-step explanation:

If a line is parallel to a side of a triangle and it intersects the other two sides then it divides those sides proportionally.

This is the case here thus

\frac{11}{121} = \frac{10}{5x + 10} ( cross- multiply )

11(5x + 10) = 1210

55x + 110 = 1210 ( subtract 110 from both sides )

55x = 1100 ( divide both sides by 55 )

x = 20

6.

the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).

[just put a dot on the number four that's right under the letter y]

the slope of the line is positive, so it goes up from left to right.

Start at the y-intercept. Move up 2 and then move right 1.

You are now at the point (1,6).

[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]

7. y= -1/2-3

8. y=3x+4
