G(t)=2+5<br>f(t) = -1² + 5<br>Find (8 + f)(t)​
jolli1 [7]

Answer:

Step-by-step explanation:

Given that,

G(t) = 2+5

F(t) = -1^2 + 5

= (-1 x -1) = 1

Therefore, F(t) = 1 + 5

G(t)= 7

Substitute 7 for(t)

F(7) =1+5

To find (8+f)(t)

Substitute all for t

(8+6)x7

=(14)x7

=98

13.) Solve for M<br> 14.) Solve for A<br> 17.) Solve for H
brilliants [131]

Answer:

See Below (Isolate the variables)

Step-by-step explanation:

13) d = 4AM solve for M

Divide both sides by 4A

\frac{d= 4AM}{4A}

\frac{d}{4A} = M

14) \frac{A}{6} = f+h  solve for A

Multiply both sides by 6

A = 6( f+h)

15) h - m = qb solve for H

Add m to both sides

h - m = qb

  + m   +m

h = qb + m

Nastasia [14]

Answer:

Karson's average speed on his way home was 28 miles per hour.

Step-by-step explanation:

Since Karson drove from his house to work at an average speed of 35 miles per hour, and the drive took him 20 minutes, if the drive took him 25 minutes and he used the same route in reverse, to determine what was his average speed going home, the following calculation must be performed:

60 = 35

20 = X

20 x 35/60 = X

700/60 = X

11.666 = X

25 = 11,666

60 = X

60 x 11.666 / 25 = X

27.99 = X

Therefore, Karson's average speed on his way home was 28 miles per hour.
