Y=mx+b is the equation to finding slope
Answer:
Not parallel.
Step-by-step explanation:
If the slopes are the same they are parallel.
So we convert each one to slope-intercept form:
-5x - 4y = -3
-4y = 5x - 3 Divide both sides by -4:
y = -5/4 x + 3/4.
Slope = -5/4.
-5x – 5y = -3
-5y = 5x - 3 Divide both sides by -5:
y = -1 x + 3/5.
Slope = -1.
The slope are different - so NOT parallel.
Answer:
Step-by-step explanation:
Slope is equal to the change in y over the change in x.
The change in x is equal to the difference in x-coordinates, and the change in y is equal to the difference in y-coordinates .
Substitute in the values of x and y into the equation to find the slope.
Simplify.

X=popcorn
x - 3.50=drink
2x+ 4(x-3.50)=32.50
2x+4x-14=32.50
solve for x
C) $694.25
Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:
400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25
Then u add the interests together:
28+16.25 = 44.25
Finally you add that to the amount you started with:
$650+$44.25= $694.25
