Karl wants to rent a bike for at most $55. He can rent a bike for $7 per hour plus a $9.50 flat fee. Any portion of an hour is c
Papessa [141]
Answer 6 hours
Reason
7x + 9.50 = 55
-9.50. -9.50 subtract from both sides
_____________
7x = 45.50

Divide both sides by 7 to isolate x
X = 6.5
So he can rent for 6 hours (the .5 would be charged as a full hour per the problem)

A) {y=2x
sladkih [1.3K]

We can see that

both lines intersects at origin

so, the solution is x=0 and y=0

now, we will check each options

option-A:

y=2x

y=-4x

now, we can set them equal

and then we can solve for x

-4x=2x

6x=0

x=0

now, we can find y

y=2*0

y=0

so, solution is x=0 and y=0

so, this correct...........Answer

a line goes through the point(6,-2)and has a slope of -3 what is the value of a if the point (a,7) lies on the line​
yaroslaw [1]

Answer:

The value of a is "3", to complete the coordinate point (3,7) on the line.

Step-by-step explanation:

We are given the slope of the line, and also one point through which the line passes. Therefore, we can find the actual equation of the line by using the slope-point form of the line:

y-y_0=m(x-x_0)\\y-(-2)=(-3)(x-6)\\y+2=-3x+18\\y=-3x+18-2\\y=-3x+16

Now, we need to find which value of "x" renders a y-value of "7", to complete the coordinate pair (a, 7) as requested. Therefore, we ask for the y-value in the previous equation to be "7", and solve for its associated x-value:

y=-3x+16\\7=-3x+16\\7-16=-3x\\-9=-3x\\x=\frac{-9}{-3} \\x=3

Therefore, x = 3
