Answer:
3
Step-by-step explanation:
The scale factor multiplies each coordinate value. If the scale factor is k, then we have ...
D' = kD
(36, -12) = k(12, -4) = (12k, -4k)
k = 36/12 = -12/-4 = 3
The scale factor of the dilation is 3.
Answer:
C
Step-by-step explanation:
x^2/12.25 + y^2/4 = 1
Answer:
see the explanation
Step-by-step explanation:
we have
RGK≅MQB
Remember that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
Corresponding sides are named using pairs of letters in the same position on either side of the congruence statement
so
RG≅MQ -----> RG and MQ are corresponding sides
GK≅QB -----> GK and QB are corresponding sides
RK≅MB -----> RK and MB are corresponding sides
Corresponding angles are named using a letter in the same position on either side of the congruence statement
so
∠R≅∠M ----->∠R and ∠M are corresponding angles
∠G≅∠Q ----->∠G and ∠Q are corresponding angles
∠K≅∠B ----->∠K and ∠B are corresponding angles
the formula for decigrams to kilograms is divide the mass value by 10,000, so the answer would be 0.0091357
Answer:
The slope of the line is 4.
Step-by-step explanation:
Recall that slope = rise over run: rise / run.
From the table we see that if x changes from 0 to 4, a run of 4, y changes from -1 to 15, a rise of 16, the slope of this line must be
m = rise / run = 16/4 = 4
The slope of the line is 4.
