Answer:
(for the second one)
y = 4x + 10
solution:
so first you have to find the slope, there is an equation for it. it is y2 - y1/ x2 - x1 or just y1 - y2/ x1 - x2 . so input the easiest points. id say f(0) and f(1)
so it will look like
2 - 6/0 - 1
-4/-1
4
so you can now write the equation as
y = 4x + b
now you have to find the y-intercept so input a point. i dont think you should input a point you used to find the slope because you could have made a mistake calculating so lets input f(2)
sooo
18 = 4(2) + b
18 = 8 + b
b = 10
so the function for the second one is y = 4x + 10
Step-by-step explanation:
7x = 2x + 5
7x - 2x = 5
5x = 5
x = 1
Answer:first choice
Step-by-step explanation:
25+12.50h<_ 100
<_ means he can spend exactly 100 or less because that's all he has
Subtract 25 on both sides
12.50h<_ 100-25
12.50h<_ 75
Divide by 12.50
h<_ 6
Answer: 4 years
Step-by-step explanation:
144 + 8(4) = 176
108 - 5(4) = 88
88 x 2 = 176
Answer:
Speed = 1050 meters per seconds
Distance =10500 meters
Step-by-step explanation:
Car traveling at a speed of 63 kilometers per hour
Let us convert this into meter per second
Speed = kilometers per hour
Speed = --------(A)
1 kilometer = 1000 meters
1 hours = 3600 seconds
Replacing them in (A)
Speed =
Speed = meters per seconds
Speed = meters per seconds
Speed = 1050 meters per seconds
Distance = speed x time
Speed = 1050 mt per sec
time = 10 sec
Distance = 1050 x 10 = 10500 meters
