X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y
Answer:
A
Step-by-step explanation:
Let's try choice A.
y = -5x-4
(10, -52)
-52 = -5(10)-4
-52 = -50-4
-52= -54
-52 is not equal to -54, so A is the answer.
<em> x₁ = - 1</em>
<em> x₂ = 2</em>
- Step-by-step explanation:
<em>2²ˣ⁺¹ - 9ₓ2ˣ + 4 = 0</em>
<em>2²ˣₓ2 - 9ₓ2ˣ + 4 = 0</em>
<em>2ˣ = n</em>
<em>2n² - 9n + 4 = 0</em>
<em>2n² - n - 8n + 4 = 0</em>
<em>n(2n - 1) - 4(2n - 1) = 0</em>
<em>(2n - 1)(n -4) = 0</em>
<em>2n - 1 = 0 => n₁ = 1/2</em>
<em>n - 4 = 0 => n₂ = 4</em>
<em />
<em>2ˣ = 1/2 => 2ˣ = 2⁻¹ => x₁ = - 1</em>
<em>2ˣ = 4 => 2ˣ = 2² => x₂ = 2</em>
A=LW
7x^3-42x^2=L(7x^2)
7x^2(x-6)=L(7x^2)
divide both sides by 7x^2
x-6=L
legnth=x-6
13. biased becasue they call documentary boring and action movie exiting, that is subjective, they should say, documentary or action movie, and not dexscribe it
