graph a
Step-by-step explanation:
y has to be less than the line
postive slope
the only graph that has both is graph a
Answer:
10x - 3y = -109 .
Step-by-step explanation:
x^2 + y^2 = 109
Implicit Differentiation:
2x + 2y.y' = 0
y' = -2x/2y = -x/y
So at the point (-10,3) the gradient of the tangent is -(-10)/3 = 10/3.
Equation of the tangent:
y - y1 = m(x - x1)
y - 3 = 10/3(x + 10)
y - 3 = 10/3 x + 100/3
3y - 9 = 10x + 100
-109 + 3y = 10x
10x - 3y = -109
You should try it with the app photomath it should give you the right answer
Answer:
(0,15)
Step-by-step explanation:
The Y-intercept is when X=0, so plug in x=0 into the given equation. 5(0)+8y=120. Now solve for Y. 8y=120, y=15. So When x=0, y=15: this is the coordinate (0,15).
8*3+6-2
8*3=24
24+6=30
30-2=28
8*3+6-2=28
