Answer:
84miles
Step-by-step explanation:
Step one:
given data
we are told that the equation that describes the car's speed is
d = 70t-----------1
<em>From the equation, we can see that the speed with which the car is traveling is 70miles per hour, while we are expected to find the distance d when the time is 1.2 hours.</em>
<em />
Required
The distance d at 1.2 hours
Step two:
substituting in the expression we have
d= 70*1.2
d=84miles
Answer:
7. y = x + 4
8. y = -3x - 2
Step-by-step explanation:
7. m = 1 , b = 4
y = mx + b will be y = x + 4
8. (1,-5) and (-3,7)
Slope (m) = 7 - (-5) / -3 - 1
= 7 + 5 / -4
= 12 / -4
= -3
y = mx + b will be y = -3x -2

Answer:
x=2
Step-by-step explanation:
5(7-x)-3(x+4)-4=4(x-3)+7
35-5x-3x-12-4=4x-12+7
19-8x=4x-5
+8x. +8x
24=12x
x=2
