Answer:

10x+9

Step-by-step explanation:

Here, f(x) = 2x-5 & g(x) = 5x + 7

Then, F(g(x)) = f(5x+7) = 2(5x+7)-5 = 10x + 14 -5

= 10x+ 9

Citrus2011 [14]

Answer:

She will receive 64 cents in change.

Step-by-step explanation:

Cost per pound of ham = $4.99

Pounds bought = 1.5

Cost of 1.5 pounds = 4.99 * 1.5 = $7.485

Cost per pound of other item = $2.50

Pounds bought = 0.75

Cost of 0.75 pounds = 0.75 * 2.50 = $1.875

Total = 7.485 + 1.875 = $9.36

Amount paid = $10

Change received = 10 - 9.36 = $0.64

Therefore,

She will receive 64 cents in change.

Dan pays £714.73 a year on his car insurance
LenaWriter [7]

Answer:

The Current Insurance cost = $685.43

Step-by-step explanation:

Given that Dan pays £714.73 a year on his car insurance.

Reduced Percentage = 4.1%

so

Reduced Amount =  4.1% × 714.73

                             = [4.1 / 100] × [714.73]

                             = 0.041 × 714.73

                             = $29.30

The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.

so

Current Insurance cost = 714.73 - 29.30

                                       = $685.43

Therefore, the Current Insurance cost = $685.43

Which of the point-slope equations below are correct for the line that passes through points (-4,-14) and (1,3)?
Scrat [10]
(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5

y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one

y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one
