Answer:
30 =z
Step-by-step explanation:
-15 = z/-2
Multiply each side by -2 to isolate z
-2 * -15 = z/ -2 * -2
30 =z
Answer:
right angle
Step-by-step explanation:
We let x square =y
so x to the power 4 = y square
and we get
To find the zroes, we need to set f(y) to 0 and solve for y .
Now we use completing the square method
Now we do the back substitution.
and
Answer:
Step-by-step explanation:
A dilation is an enlargement or reduction of an object by a scale factor and with a center of dilation. The scale factor refers to the change in size. The center of dilation is a point about which we are dilating an object.
The dilation with the center of dilation at the origin and a scale factor of k has the rule
This means that the image of the point with coordinates (x,y) after the dilation by a scale factor of k with center of dilation at origin will have coordinates (kx,ky).
