I'm guessing it is 10? or 7?
Number of choices per question = 5
Number of wrong answers = 4
P(wrong answer) = 4/5
Answer: 4/5
Assuming the equation is x^2 + y^2 = 1, then that's a circle, with radius 1, centered on the origin [0,0].
So there are two tangents at x = 0. They are y = 1, and y = -1 (horizontal lines).
There is one tangent at x = 1. It is x = 1 (a vertical line).
There is no tangent at x = 35, because the original equation has no solution at x = 35.
Answer: x<4
Step-by-step explanation: Let's solve your inequality step-by-step.
2x+1<9
Step 1: Subtract 1 from both sides.
2x+1−1<9−1
2x < 8
Step 2: Divide both sides by 2.
2x
/2 < 8
/2
x<4
Answer:
10
Step-by-step explanation:
X = -1 so, we have:
3·1² + 1
3² + 1
9 + 1
10
