A. Y= -7
X=2
4x+2y=-6
+(3x-2y=-8
Answer:
The simplified version of this expression is 11 + a.

Put the first equation in slope-intercept form, or y = mx + b. Start by subtracting y from both sides.
2x - y = -10, subtract 2x from both sides.
-y = -10 - 2x
Divide both sides by negative one.
y = 10 + 2x
To find the slope when the equations are in slope-intercept form you look at the coefficient of x. The first equation has the slope of 2 (which we just found), and the second equation has the slope of -2.
Parallel lines have the same slope and perpendicular lines have opposite reciprocal slopes. Since 2 and -2 are neither of these, your answer is neither.
Answer:
Brand A = $0.19 per pencil
Brand B = $0.18 per pencil
Better Buy = Brand B (costs less)
Step-by-step explanation:
To find unit price for each, we divide the total with the number of pencils.
So, <u>Brand A:</u>
5.29/28 = $0.19 per pencil
And, <u>Brand B:</u>
8.47/48 = $0.18 per pencil
As we can see, Brand B pencils are around 1 cent less per pencil than Brand A pencils. So, we can say Brand B are a Better Buy.
