Answer:
Step-by-step explanation:
1. Y varies jointly as R and T
Y = k*R*T
Y = kRT
Where,
k = constant of proportionality
2. B is directly proportional to the square of A and inversely proportional to the cube of C.
B = k(A²) / C³
B = kA²/C³
Where,
k = constant of proportionality
Hi Kimberly!
-(19 - 3s) - (8s + 1) = 35
-19 + 3s -8s - 1 = 35
-19 - 1 + 3s - 8s = 35
-20 - 5s = 35
-5s =35 + 20
-5s = 55
Divide both sides by -5
-5s/-5 = 55/-5
s = -11
A+ for Algebra guaranteed! <span />
Answer: c
Step-by-step explanation:
Because both are slopes its confusing but its c bc its in the even quadrant
Answer:
(-1,6)
Step-by-step explanation:
y=-x+ 7
Let x = -1
y = -1+7
y = 6
I'll do 3 and 4, and you can do 5 and 6 on your own!
For 3, we know that a perpendicular line's slope is -1/the other one, so the form is y=x/5+b (b being any number). Plugging -5 and -3 in, we get -3=-1+b. Adding 1 to both sides, we get -2=b and our equation being y=x/5-2 (since our standard form is y=mx+b with y and x remaining variables)
For 4, parallel means the same slope, so we have y=-2x/5+b. Plugging (2,4) in, we get 4=-4/5+b. Adding 4/5 to both sides, we get 4+4/5=b and our equation being y=-2x/5+4+4/5
