As it has a maximum value the coefficient of x^2 will be negative
The vertex will be at (-8,2) so in vertex form it is
y = a(x + 8)^2 + 2
and as it passes through (-7,-1) we have:
-1 = a(-7+8)^2 + 2
-1 = a + 2 so a = -3
answer is y = -3(x + 8)^2 + 2
in standard form this is y = -3x^2 -48x - 190
Answer: <em>here are the graphs. the one with the sloped line is </em>5x - 3y ≤ -15.<em> the one with the straight line is </em>y ≥ 4.
Answer:
This the formula for the Pythagorean Theorem.
Step-by-step explanation:
This is the formula for the Pythagorean Theorem but its written in a different way but it will give you the same answer.
So first you will be given two sides which will be represented as leg a and leg b.
So you would plug in the two numbers in the equation c = square root of 18^2 + 12^2
Now you would find 18^2 which equals 324
Then you would find 12^2 which equals 144
Add them together and get 468
To get what c equals or the hypotenuse you have to find the square root of 468.
The square root of 468 is 21.633 but you round it to the nearest tenth and get 21.6
