Answer: 6 and 14 for the 1st 2 questions and for the last 2 its 18 and 22
Step-by-step explanation:
Step-by-step explanation:
When a dilation in the coordinate plane has the origin as the center of dilation, you can find points on the dilated image by multiplying the x- and y-coordinates of the original figure by the scale factor.
so, J is (1, 4).
therefore, J' is then (1×3.5, 4×3.5) = (3.5, 14).
that eliminates already the first 2 answer options.
next, let's use M (1, 1)
M' is then (3.5, 3.5)
so, the right answer is the 4th answer option.
B false standard deviation is the square root of variance
Answer:
X= -15
Step-by-step explanation:
1/5 (5x-10)=3 (2/3x + 4) + 1
5x - 10/5 = 3 (2x/3 + 4) + 1
5x - 2*5/5 = 3 ((2x) + 3*4/3) + 1
X= -15
