Joe is going to travel to dallas. he lives 320 miles away and can average 69 miles per hour. use an equation to represent the distance d from dallas in terms of h, the number of hours joe has traveled.
a.
d = 69h
c.
d = 320 + 69h
b.
d = 320 - 69h
d.
d = 320h + 69

D = 69h

Step-by-step explanation:

Given : Joe is going to travel to Dallas. He lives 320 miles away and can average 69 miles per hour.

To Find: Use an equation to represent the distance D from Dallas in terms of h, the number of hours Joe has traveled.

Solution :

Let distance be D

His speed is 69 miles per hour

He took h hours to cover D distance

formula: Distance = Speed*Time

Putting the given values in formula

⇒ D = 69 h

Thus Option a is correct : D = 69h

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
