Answer:
A) 8x + 9y = −3
B) 6x + 7y = 1
We multiply A) by -(6/8)
A) -6x -6.75y = 2.25 then we add this to equation B
B) 6x + 7y = 1
.25y = 3.25
y = 13
and x = -15
Step-by-step explanation:
|n|=3
n=+3;n=-3
|n|=14
n=+4; n=-4
|n|=1
n=+1; n=-1
To multiply like that you can break it up or get rid of all the zeros multiply normally then add the zeros when you are done or you can just multiply as usual. Or you can use a calculator I got the answer 4.8000054e+16 when I put it in a calculator but my self i got 52000008760000000 I think I messed up with all the zeros but i tried. Have a great day!
Someone help please I need to know this answer as well!!!
Answer:
C. 3/2x
Step-by-step explanation:
Firstly, we know that the slopes are the same because parallel lines have the same slope. Then we can find the y-intercept by using the slope and point in slope-intercept form.
y = mx + b ---> plug in known values
3 = (3/2)(2) + b ---> Multiply
3 = 3 + b ---> Subtract 3 from both sides.
0 = b
Since the intercept is 0, you will not see a number after the slope and x.
