Answer:

See below for answers (in bold) and explanations

Step-by-step explanation:

Part A: (h+t)(x) = h(x) + t(x) = (2x-5) + (6x+4) = 2x - 5 + 6x + 4 = 8x - 1

Part B: (h*t)(x) = h(x) * t(x) = (2x-5) * (6x+4) = (2x)(6x) + (2x)(4) + (-5)(6x) + (-5)(4) = 12x² + 8x - 30x - 20 = 12x² - 22x - 20

Part C: h(t(x)) = h(6x + 4) = 2(6x + 4) - 5 = 12x + 8 - 5 = 12x + 3

1. Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and
Andru [333]

Suzette ran for 1.6 hours and biked for 2.4 hours.

Let x = total hours Suzette ran.

Let y = total hours Suzette biked.

The equation to solve the question will be:

x + y = 4 ...... i

6.5x + 14y = 44.75 ....... ii

From i, y = 4 - x

Put the value of y into equation ii

6.5x + 14y = 44.75

6.5x + 14(4 - x) = 44.75

6.5x + 56 - 14x = 44.75

Collect like terms

6.5x - 14x = 44.75 - 56

-7.5x = -11.25

x = 11.25/7.5

x = 1.6 hours

Since x + y = 4

1.6 + y = 4

y = 4 - 1.6

y = 2.4 hours.

Suzette ran for 1.6 hours and biked for 2.4 hours.
