She bought 8 quarts of juice. Each gallon is 4 quarts, so 1 and a half would be 6, plus the 2 quarts she already bought, meaning she bought 8 quarts. Now, the only question is why anyone would name their child Cesar.
Answer:
(-1, 3)
Step-by-step explanation:
x - 5y = -16 [Equation 1]
-x + 3y = 10 [Equation 2]
<u>Adding both equations</u>
- x - x - 5y + 3y = -16 + 10
- -2y = -6
- y = 3
- x - 5(3) = -16
- x - 15 = -16
- x = -1
<u>Solution</u> : (-1, 3)
False, since if there are two perpendicular lines with gradients m1 and m2, then m1*m2 = -1.
Taking this example -5/2 multiplied by 5/2 is equal to -25/4, which is not equal to -1.
To find the actual gradient of the perpendicular line you would have to divide -1 by -5/2, which gives you 2/5.
