Answer:
The slope is 3 and the y intercept is -7/4
Step-by-step explanation:
We need to get the equation in the form
y = mx+b where m is the slope and b is the y intercept
12x - 4y =7
Subtract 12x from each side
12x-12x -4y = -12x +7
-4y = -12x+7
Divide each side by -4
-4y/-4 = -12x/-4 +7/-4
y = 3x + -7/4
The slope is 3 and the y intercept is -7/4
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.

Define x:
------------------------------------
Let x be the calories of the old chocolate bar.
Apple = 1/4 x - 10 ←First Step : Define apple with reference to the choc
------------------------------------
Information Given:
------------------------------------
Apple = 70 Calories
------------------------------------
Find x:
------------------------------------
1/4 x - 10 = 70
1/4 x = 80
x = 320 calories
------------------------------------------------------------------------
Answer: The old chocolate bar is 320 calories.
