With A and its image one can get the dilation factor;
That is dilation scale factor = -6/-4 or 9/6 = 3/2
Therefore, to get the image of B we multiply the coordinates of B by the dilation factor;
(1,4) 3/2 = (1.5, 6)
Thus the image of B = (1.5,6)
-2y=-3x+4
y=-3x+4/-2
y=3/2x-2
Answer:
27
Step-by-step explanation:
Boys to girls is 2:3
and there are 18 boys so that means the 2 in 2:3 is actually 18
and 2 x 9 = 18 , so you would need to also multiply 3 by 9.
3 x 9 = 27
18:27
there are 27 girls
Step-by-step explanation:
JNM is a right-angled triangle with JM being the Hypotenuse.
we know JN = 20
NM = KL, and that is a side of the right-angled triangle JKL, aber we know JK and JL.
KL² = JL² - JK² = 35² - 16² = 969
KL = NM = sqrt(969) = 31.12876483...
and now,
JN² + NM² = JM²
20² + 969 = JM²
400 + 969 = JM²
1369 = JM²
JM = 37
This problem can be solved through the concept of ratio and proportion such that the ratio between $0.43 and $100 should be the same as that of her insurance premium, x, and the cost of her new home.
$0.43 / $100 = x / $387,500
The value of x from the equation generated above is,
x = $1666.25
Thus, the answer is letter A.
