Answer:
C. x=4
Step-by-step explanation:
Slope-intercept form uses the following formula:
y = mx + b
In this case, "m" is the slope of the line and "b" is the y-intercept. We'll now restate the equation found in the question above:
y = -5x + 1
We can now see that a value of (-5) is in the "m" position while a value of (1) is in the "b" position. Therefore, we can determine that the slope of the line is (-5) and the y-intercept is (1).
I hope this helps!
Answer:
Wonka bars=3 and Everlasting Gobstoppers=24
Step-by-step explanation:
let the wonka bars be X
and everlasting gobstoppers be Y
the objective is to
maximize 1.3x+3.2y=P
subject to constraints
natural sugar
4x+2y=60------1
sucrose
x+3y=75---------2
x>0, y>0
solving 1 and 2 simultaneously we have
4x+2y=60----1
x+3y=75------2
multiply equation 2 by 4 and equation 1 by 1 to eliminate x we have
4x+2y=60
4x+12y=300
-0-10y=-240
10y=240
y=240/10
y=24
put y=24 in equation 2 we have'
x+3y=75
x+3(24)=75
x+72=75
x=75-72
x=3
put x=3 and y=24 in the objective function we have
maximize 1.3x+3.2y=P
1.3(3)+3.2(24)=P
3.9+76.8=P
80.7=P
P=$80.9
