X° +110° = 180* . . . . . "linear" angles
x = 70
x° +112° +y* +88° = 360° . . . . . sum of interior angles of a quadrilateral
y° +270° = 360°
y = 90
The values of the variables are
.. x = 70
.. y = 90
Answer:
f(x) = (x + 4)² - 3
Step-by-step explanation:
The equation of a quadratic function in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² + 8x + 13
To obtain f(x) in vertex form use the method of completing the square
add/ subtract (half the coefficient of the x- term)² to x² + 8x
f(x) = x² + 2(4)x + 16 - 16 + 13
f(x) = (x + 4)² - 3 ← in vertex form
Answer:
-40
Step-by-step explanation:
Let's input x into all of the slots.
Now, let's solve!
So, the answer is -40!
The answer would be 37.4 because 10% of 34 would be 3.4 and 3.4 plus 34 would be 37.4
