Answer:
$27
Step-by-step explanation:
336/28= 12
13×2.25= 27
<h2>Steps</h2>
So to find the solutions, I will be factoring by grouping. Firstly, what two terms have a product of 12x² and a sum of -8x? That would be -2x and -6x. Replace -8x with -2x - 6x:
Next, factor 4x² - 2x and -6x + 3 separately. Make sure that they have the same quantity on the inside of the parentheses:
Now you can rewrite it as:
Now, apply the zero product property and solve:
<h2>Answer</h2>
<u>In short, x = 3/2 (1.5) and 1/2 (0.5).</u>
Answer:
Step-by-step explanation:
First one is 200 dollars for insurance which will be the constant and 15 dollars an hour which means the equation will be;
C = 15h +200 (Sinking Rivers)
Second one is $30 an hour and $110 for insurance which is the constant so he equation is;
C = 30h + 110 (Floating Down The Stream)
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Answer:
8(3y+11x)
