Answer:
A, C, D
Step-by-step explanation:
One rule of thumb is just add up two sides and if its greater than the third value that side works. (make sure to test it for all of the sides though)
Answer:B
Step-by-step explanation:
if you do A then you are losing 50% of your profit on for items
if you do see then you are giving 40% discount on that item which means you would only get 60% of the one item.
<u><em>Therefore your best bet is B because you still get the price of two items</em></u>
Step-by-step explanation:
24x^2_54x_15=0
(12X +3 ) ( 2X _5 ) . = O
12x +3 =0
X= - 1/4
or
2x _ 5=0
X = 5/ 2
If you would like to calculate 57 divided by 8, you can do this using the following steps:
57 divided by 8:
57 / 8 = 7 1/8 = 7.125
The correct result would be 7 1/8 or 7.125.
Answer:
So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.
