Answer:
O f(x) = -x-1
Step-by-step explanation:
We want to isolate the 'y' variable, so we will subtract 7 from both sides.
y = x + 6 - 7
y = x -1
Answer:
x = 7.5
Step-by-step explanation:
Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.
Given that the length of sides of the smaller triangle are; 5, 13, 12.
Given also that the length of the dilated triangle are; x, blank, 18.
Comparing the length of the last sides of the two triangles, we have;
(scale factor x 12) + 12
= (
x 12) + 12
= 6 + 12
= 18
Thus the scale factor for the dilation is
. So that:
x = (
x 5) + 5
= 2.5 + 5
= 7.5
x = 7.5
And also,
blank = (
x 13) + 13
= 6.5 + 13
blank = 19.5
Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18
Answer:
100 times
Step-by-step explanation:
multiples of 3 on a number cube are 3 and 6
probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3
1/3 x 300 = 100
