Answer:

1/2

Step-by-step explanation:

The scale factor is 1/2.

Look at the length of a side on the first triangle, and then compare it to the second one. The first base is 16, and second one is 8. The second is 1/2 of the first, so that is the scale factor.

Answer:

x = −3 and x = −2

Step-by-step explanation:

x^2 + 5x = −6

Add 6 to each side

x^2 + 5x+6 = −6+6

x^2 +5x+6 =0

Factor

What 2 number multiply to 6 and add to 5

3*2 =6

3+2 =5

(x+3)(x+2) =0

Using the zero product property

x+3 =0             x+2 =0

x+3-3=0-3         x+2-2=0-2

x=-3                       x=-2

Rotation 180 counterclockwise around the origin of the point (-3,-7)
yaroslaw [1]

Answer: (3 , 7)

Step-by-step explanation: When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative. Since x and y are already negative, they become positive due to the double negative rule.
