First question, answer is A, the starting point in the graph shows it’s (0,150) while the slope is 30, look at the labeled axis.
second question, i have to do work for it, i can answer it later. remind me. but in order to find the slope, the formula is delta y over delta x. then to find the y intercept, do what’s called “collect the evidence”. this is when you fill out all needed info, it will look like this- y= x= m= b= ??
idk ab the third question, they would all make the function fine?? idk i’m confused, it doesn’t make sense
fourth question, the answer would be B
Answer:
The correct answer is 54 miles per hour
Step-by-step explanation:
To solve this problem we have to use the formula of
Speed=Distance/time
Both, car an truck made the same distance, so
Distance car=Speed car*time car
Distance truck =Speed truck*time truck
Distance car=Distance truck
So Speed car*time car =Speed truck*time truck
Speed car =Speed truck* time truck /time car
Time truck = time car +2 ( truck leaves 2 hours before)
Time car =10
Speed car =45 miles per hour* 12 /10
Speed car = 54 miles per hour

Answer:
(-12,2)
Step-by-step explanation:
2x + 4y = -16
2y - x = 16
Multiply the bottom part by 2.
2x + 4y = -16
4y - 2x = 32
Add the equations and the answers to the equations up, and they will equal each other.
(2x + 4y) + (4y - 2x) = -16 + 32
8y = 16
y = 2
Plug y = 2 to the 2nd equation.
2*2 - x = 16
4 - x = 16
Subtract 4 from both sides.
-x = 12
Multiply both sides by -1.
x = -12
