Angle 3 = angle 7 [alternate angles]
=> 4x+1 = 2x + 21
=> 4x-2x = 21-1
=> 2x = 20
=> x = 20/2
=> x = 10
Answer:
5:4
Explanation:
The scale factor would be 15:12 because the sides are corresponding. This ratio simplifies to 5:4 when divided by 3.
Graph both equations on one coordinate plane. Wherever the equations intersect is your answer.
Answer:
<h2>
y+9=-10(x-6)</h2>
Step-by-step explanation:
First you find the slope by setting your y2-y1 over your x2-x1 and that gives you -9-1 / 7-6.
simply that and it gives you -10/1 =-10
then you use the formula y-y1= m(x-x1) . So basically you filling in the blanks
and that gives you y+9=-10(x-6)
