I believe the answer is C
Answer:
-14
Step-by-step explanation:
(-5)-2-8+1
-5-2-8+1
-7-8+1
-15+1
-14
Subtract the 2 equations
7x+2y=-19
- -x+2y = 21
--------------------------
8x +0y=-2
x= -1/4
3/2 = 9/6 blackberries, then 7/3 = 14/6 blueberries. 14-9=5, and so then 5/6 pints of blueberries was used more than blackberries.
the answer is 5/6! : )
In slope-intercept form, we have these values (y = mx + b):
m = slope
b = y-intercept
Change the equation from standard form to slope-intercept form.
-9x + 7y = 28
-9x + 9x + 7y = 28 + 9x
7y = 28 + 9x
7y/7 = 28/7 + 9x/7
y = 4 + 9/7x
y = 9/7x + 4
Therefore, the y-intercept is 4.
Best of Luck!
