Answer: Ok so go back to the lesson and read the directions for this page then look at the signs and fill in the page easy
Step-by-step explanation:
To solve this algebraically, you can first factor out a 3:

Then, you can factor (I'm using guess and check) and my answer is -4 and 2:

From here on, finding 0s is very easy. You just solve for x in the parentheses. So,
the 0s are when x = 4, and x = -2. Remember, (4-4) = 0, and (-2+2) = 0, that's what you want.
The diameter of the circle would be a line going through the center of the circle connecting to both sides.
The radius of a circle would be a line only going to the the center, or in other words, half the circle.
I hope this makes sense!
Sum of angles in a triangle is 180°:
180 - 50 - 62 = 68
Sum of angles in a triangle is 180°:
180 - 80 - 53 = 47
Sum of angles in a triangle is 180° / Vertically opposite:
180 - 68 - 47 = 65°
Answer: 65°
Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
