a and c
Step-by-step explanation:
Answer:
x=4 y=1 or (4,1)
Step-by-step explanation:
Use point-slope formula---> y-y1=m(x-x1)
Let y1 equal -9, let x1 equal -10, and let m equal 3
Plug in and solve
y-(-9)=3(x-(-10)
y+9=3(x+10)
y+9=3x+30
Subtract nine from both sides
y=3x+21(This is slope form, i might have gone too far)
Answer:
7x^2 + 29xy -2y^2 + 8y
Step-by-step explanation:
3x(x+5y)+2y(7x-y)+4(x^2+2y)
Break all the brackets and you would hot:
= 3x*x + 3x*5y + 2y*7x - 2y*y + 4*x^2 + 4*2y
= 3x^2 + 15xy + 14xy -2y^2 + 4x^2 + 8y
= 3x^2 + 4x^2 +15xy + 14xy - 2y^2 + 8y
= 7x^2 + 29xy -2y^2 + 8y
Hope this help you :3
