laiz [17]

Answer:

<h2>y=8</h2>

Step-by-step explanation:

4y-4=28

4y=28+4

4y=32

y=32/4

y=8

now plug in 8 for y and check the equation true:

4y-4=28

4*(8)-4=28

A car and a limo each drive along a straight road between two points. Using the points on a map that the city created, the car w
garik1379 [7]
The path of the car and the limo are straight lines. To determine the equation of the lines of the paths, the slopes must be determined. Let m1 = slope of car m2 = slope of limo so, m1 = (7 + 7)/(5 + 2) = 2 m2 = (-5 -9)/(3+4) = -2 therefore the equations are car: 2x – y = 2(5) –(7) 2x – y = 3 Limo: 2x + y = 2(3) – 5 2x + y = 1 Solving the intersection of the equations (using a calculator) x = 1 y = -1

£250 in the ratio 4 to 1
Andrej [43]
In the event that you are asking to devide parts, we will use the equation   

·X+X²=Y

We Plug in our parts

·4x+1x=5x(Y)

We then substitute

·4x+1x=250(5x)

Then we devide Y(250) by the number of parts total.

·5 parts total.

·250/5=50

·1 part=50.

Next we substitute.

·200(4)+50(1)=250(5)

-In conclusion your answer is 50£:200<span>£, i hope this is the answer you are looking for, feel free to post your questions here in brainly in the future.</span>
