-3a - 3 = -2 + 3p ˢᴼᴸᵛᴱ ᶠᴼᴿ ᴬ
skad [1K]

Hi!

-3a - 3 = -2 + 3p

-3a=3p+1

\frac{-3a}{3}=\frac{3p+1}{-3}

Answer------>a=-p+\frac{-1}{3}

Explanation: <u><em>First you had to add by 3 from both sides. It gave us -3a=3p+1. Then divide into -3 from both sides. It gave us -3a/-3=3p+1/-3, or a=-p+-1/3 is the right answer. Hope this helps! And thank you for posting  your question at here on Brainly. And have a great day. -Charlie</em></u>

When graphing a circle can the the radius be negitive?
Lerok [7]
No. The circle can be composed of completely negative coordinates, but the radius is always a positive value. You can prove this by plugging any point and the center into the distance formula.

What is the y-intercept of the line perpendicular to the line y = 3/4x + 3 that includes the point (-3, -3)
kipiarov [429]
A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4

The final equation is y= -4/3x + 21/4
The y intercept is (21/4).
