Answer:

x = 33/8

y = 25/4

Step-by-step explanation:

4y - 3 = 22

y = 2x - 2

4y - 3 = 22

4y - 3 - 22 = 0

4y - 25 = 0

4(2x - 2) - 25 = 0

8x - 8 - 25 = 0

8x - 33 = 0

8x = 33

x = 33/8

y = 2x - 2

y = 2(33/8) - 2

y = 33/4 - 2

y = 33/4 - 8/4

y = 25/4

5(5t + 1) = 25t-7<br> Can someone help me with this solution??
masha68 [24]
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest

5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===
