Step-by-step explanation:
i. 3x-1=20
or, 3x= 21
x= 7
ii. 3x+1= 22
3x= 21
x= 7
iii. 2x-5=99
2x= 104
x=52
iv. g(3)= 3+5/2= 11/2
g(0)= 0+ 5/2=5/2
g(-3)= -3+5/2 = -1/2
x+5/2= 0
so, x= -5/2

Answer:
h = -8.5
Step-by-step explanation:
10.35+2.3h=-9.2
Subtract 10.35 from each side
10.35-10.35+2.3h=-9.2-10.35
2.3 h =-19.55
Divide each side by 2.3
2.3h/ 2.3 = -19.55/2.3
h =-8.5
2. - Kevins average speed is 67.5 mph
Step-by-step explanation:
Rise of y-value = (-4) - (3) = -7.
Run of x-value = (8) - (6) = 2.
Slope of the line = Rise / Run = (-7) / (2) = -3.5.
