Hi there!
To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18
Hope this helps!
Answer:
178
1900 = 5(x+202)
Step-by-step explanation:
Sasha= 5 times Bess and Jeremy
1900 = 5 (202 + X)
/5 /5
380 = 202 + x
-202 -202
178 = x
It would be -6 x+9 i think.
notice, if the original area was πr², then the new area has a factor in front of it, that much.
