Answer:
1.5 or -5
Step-by-step explanation:
2x²+7x-15=0
Divide by 2:
x²+7x/2-15/2=0
x=-7/2/2 ± √49/4(4)+15/2
=-7/4 ± √49/16+120/16
=-7/4± √169/16=-7/4 ±13/4
=6/4 or -20/4
=1.5 or -5
Answer:
A' = (3, 6)
B' = (9, -3)
C' = (-12, -6)
Step-by-step explanation:
you can mulitply both the x and y coordinates of each point by the scale factor (3)
point (1, 2) becomes point (3, 6)
(3, -1) becomes (9, -3)
(-4, -2) becomes (-12, -6)
hope this helps!! have a lovely day :)
<em>{this is why whoever wrote the problem gave that hint--you can follow through on that logic, but just remember that it has to be a scaled version of the original figure--so the ratios between points (and x/y values) must be consistent}</em>
Answer:36
Step-by-step explanation:36÷ -4 = -9
Answer: 5x + 2y ≤ $40; x,y ≥ 0
Step-by-step explanation:
5x + 2y ≤ $40
Technically, this is insufficient since it allows for purchases of negative amounts.
Really, it should be 5x + 2y ≤ $40 <u>and </u>x ≥ 0 <u>and</u> y ≥ 0. That is 3 inequalities.
No begging. ;)
