First thing to do is to solve each of these for y. The first one is y=-4x-3; the second one is y=4x-21; the third one is y=4x+21; the fourth one is y=-4x+3. From that you can tell the positive slopes are found in the second and third equations. Those are the ones we will test now for the point (3, -9). y=-9 and x=3, so let's fill in accordingly. The second equation filled in is -9=4(3)-21. Does the left side equal the right when we do the math? -9=12-21 and -9=-9. So the second one works. Just for the sake of completion, let's do the same with the third: -9=4(3)+21. Does -9=12+21? Of course it doesn't. Our equation is the second one above, y+9=4(x-3).
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.
45p² - 120p + 80
= 5(9p² - 24p + 40)
=5(3p - 4)²
-----------------------------
Answer: 5(3p - 4)²
-----------------------------
Answer:
Answer D: 4 times larger
Step-by-step explanation:
Recall that d = 2r.
Try this comparison:
Area of larger circle π(2·d/2)²
-------------------------------- = -------------- = 4
Area of smaller circle π(d/2)²
The area of the larger circle will be 4 times that of the smaller circle.
Answer:
She poured a total of 5 5/8 in the glasses
Step-by-step explanation:
To get the total, we need to multiply the amount in each glass by the number of glasses.
1 1/8 * 5 = 5 5/8
