Answer:
y=7/2x−10
Step-by-step explanation:
Let's solve for y.
7x−2y=20
Step 1: Add -7x to both sides.
7x−2y+−7x=20+−7x
−2y=−7x+20
Step 2: Divide both sides by -2.
−2y/2=−7x+20/2
y=7/2x−10
We are given a rain gutter made from folding a 12 inch wide aluminum sheet to an angle theta. The area of the opening is expressed as A(Θ) = 16 sin Θ (cos Θ + 1) where <span>Θ = 60°. we can just substitute directly the angle in degrees mode in the calculator and the answer is equal to 20.78 inches2.</span>
Answer:b?
Step-by-step explanation:
Answer:
Step-by-step explanation:
For a, you need to plugin -9 into the equations inside the boxes and solve.
y = x^2 + 3, y = 9^2 + 3, y = 81 + 3, y = 84.
y = √x - 2, y = √9 - 2, y = 3 - 2, y = 1.
For b, It's only possible for the second equation to output 0, as for the first, it's impossible for x^2 to equal -3 and add to 3 to get 0. For the second equation you can plug in 4 to get 2 - 2, which gives 0.
