Answer:

Distance travelled in  8 \frac{3}{4} hours is 659.17 miles .

Step-by-step explanation:

As given

Jill drives 75 \frac{1}{3} miles every hour .

i.e

Jill drives \frac{226}{3} miles every hour .

Now find out the distance travelled in 8 \frac{3}{4} hours .

Distance\ travelled = 8 \frac{3}{4}\times miles\ travelled\ every\ hour

Distance\ travelled =\frac{35}{4}\times \frac{226}{3}

Distance\ travelled =\frac{7910}{12}

Distance travelled = 659.17 miles (Approx)

Therefore distance travelled in  8 \frac{3}{4} hours is 659.17 miles .

What does <br> f(x) – g(x) =
andrezito [222]

Answer:

(f - g) (x)

Step-by-step explanation:

Since (x) is common between them, you can bring it out. for example,

f(x) = x +1

g(x) = 2x + 3

f(x) - g(x) = x + 1 - 2x + 3

= -x + 4

(f - g) (x) = x + 1 - 2x + 3

= -x + 4

Y=foot
x=foram

A. easy, plug 17 for x and evaluage for y
y=0.860(17)+3.302
y=14.62+3.302
y=17.922 inches


B. rate of change is slope
y=mx+b
m=slope
so
rate or change is 0.860 inches per legnth of forarm

C. what data

D. it is a function
since it is 1st degree (no exponents greater than 1 on the placeholder), and it is not a vertical line
it is a function
