28:35 because 28/7 is 4 and 35/7 is 5. So the answer is, 28:35.
Hope that helped :)
Answer:
x = - 13, x = - 3
Step-by-step explanation:
Given
x² + 16x = - 39
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 39 + 64
(x + 8)² = 25 ( take the square root of both sides )
x + 8 = ± 
= ± 5 ( subtract 8 from both sides )
x = - 8 ± 5, thus
x = - 8 - 5 = - 13 or x = - 8 + 5 = - 3
Answer:
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>
Step-by-step explanation:
1. Let's review the information provided for an answering the question correctly:
0 =1/2x^2- 3x- 2
0 = 1/2x² - 3x - 2
2. Let's find the values for a, b and c.
According to the quadratic equation, we have:
a = 1/2
b = - 3
c = - 2
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>

Answer:
A.
Step-by-step explanation:
for a single element of x there is an element in y, so observing we see that no number is repeated in the ordinate x of the coordinates
