Answer:
(a) S=
(B) S(average speed)=65.04
Step-by-step explanation:
Given
D=S*T
So, S=
and
T=11.5 Hr
D=748 Km.
S(average speed)=
=65.04 kmph
If the number was x, then you could write the expression x-5 since you show five less or subtracted from the number. Hope this helps.
Answer:
5. y = 2/3x + 1
8. y = 4/7x - 4
Step-by-step explanation:
5. (-6, -3) and (6, 5)
You can use the slope formula which is (y2-y1)/(x2-x1) to find the slope and plug it back into the slope-intercept form to find the y-intercept
(5-(-3)) / (6-(-6)) = 8 / 12 = 2/3
slope-intercept form: y=mx+b where m is the slope and b is the y-intercept
to find b you can plug in one of the coordinates and the slope
5 = 6(2/3) + b
5 = 4 + b
1 = b
y = 2/3x + 1
8. (-7, -8), (21, 8)
m = (8 - (-8)) / (21 - (-7)) = 16 / 28 = 4/7
plug in one of the coordinates and the slope to find b or the y-intercept
8 = 21(4/7) + b
8 = 12 + b
-4 = b
y = 4/7x - 4
Answer: x=6
Step-by-step explanation:−5x + 13 = −17
-13 -13
-5x = -30
divide -5 on both sides
x=6
