Answer:
The system has no solution
Step-by-step explanation:
we have
----> equation A
isolate the variable y
Divide by 3 both sides
----> equation B
Compare equation A and equation B
Their slopes are equal and their y-intercepts are different
Remember that
If two lines have the same slope, then the lines are parallel
In this problem we have two different parallel lines, so, the lines don't intercept
therefore
The system has no solution
3:8 can also be written as 3/8
12:32 can also be written as 12/32
So thus 3:8 is equivalent to 12:32
Answer:
Δx= 184.12 ft
Step-by-step explanation:
The equation you need to use is velocity as a function of displacement.
v = the speed at which the car is travelling,
and
v_o is the original speed (in this case zero).
The change in x (displacement) is how far the car travels. You will be solving for a (acceleration).
solving we get
a= 12.19
now put this acceleration value into the second case when v= 67mi/h
⇒Δx= 184.12 ft
That has a y intercept at y=-1. For every one block to the right we go three blocks up, so that's a slope of 3/1=3. So in slope-intercept form our equation is
y = 3 x - 1
Answer: third choice
She needs 23 boxes because 22.25 boxes doesn’t make sense.
The answer is 23 boxes not 22
