Phillip should buy 5 packages of erasers so he will have 60 of them. Then he should buy six packs of pencils so he will have 60 of both pencils and erasers
Answer: b) {-3, 0.5}
Step-by-step explanation:
The new equation is the original equation plus 6. Move the original graph UP 6 units. The solutions are where it crosses the x-axis.
+6 means it is a transformation UP 6 units.
Solutions are where it crosses the x-axis.
The curve now crosses the x-axis at x = -3 and x = 0.5.
Answer:
y ≤ 2x + 4 and x + y ≥ -6
Step-by-step explanation:
Graphing a system of inequalities is similar to graphing linear functions. It is best to have equations in the form of y = mx + b where m = slope and b = y-intercept. Looking at the graph, you can see that there is one line going uphill (positive slope) and one going downhill (negative slope). There are two y-intercepts, one from each line at (0,4) and (0, -6) So, only the top two equations have a y-intercept equal to 4 and -6. Then, you can find the slope of each line by choosing two points on the same line and using rise/run to find the change in 'y' over the change in 'x'.
Line #1 (uphill): (-2, 0) and (0, 4) = 4-0/0- -2 = 4/2 = 2
The only answer with a positve 2 slope and y-intercepts of 4 and -6 is the second one, so that is your answer.
Answer:
x= -6
Step-by-step explanation:
12 = -2x
Divide -2 on both sides=
-6=x
x=-6
Double Check:
-4x +12 = -6
-4(-6) +12=-6(-6)
24+12 = 36
36 = 36
8.75n=61.25
In order to solve it, you have to divide 61.25 by 8.75 in order to get your answer.
