Answer:
(in attachment)
Step-by-step explanation:
you can find the points by inputting the x-values into the equation to solve for the y-values, then connecting the plotted points to create the line.
When x=-4
y=1/2(-4)
y=-2
(-4,-2)
Repeat for all values.
Answer:
The third graph is correct for the inequality 2x + 3y > -3
Step-by-step explanation:
The slope of the graph is –2/3.
The y-intercept is –1
The area above the dashed be line is shaded.
To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.
For example: (1,1)
2(1) + 3(1) > –3
2 + 3 > –3
5 > –3 True.
Answer:
13x + 2y + 8
Step-by-step explanation:
hope it helps......
Cost of 1 plant = $ p
Cost of 4 plants = $(4p)
Cost of a 10-gallon tank = $10
Cost of a water dish = $3
Total cost = 4p + 10 + 3 = 4p + 13
Answer:
Step-by-step explanation:
8x - 20.....factor a 4 out
4(2x - 5) <=== this one is correct...not 100% sure who wrote it
8x - 20...factor out a 2
2(4x - 10) <==== this is correct
8x - 20....factor out a -2
-2(-4x + 10) <==== this is correct
8x - 20....factor out a -4
-4(-2x + 5).....nobody did this one......but somebody tried....that person didn't factor correctly
