Answer:
Y=-2x+5 (3 or C)
Step-by-step explanation:
Replace the value of x
Y= -2x(-1)+5
Solve
Y= 2+5
Y= 7
we know that
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
So
m∠O=m∠M
m∠L=m∠N
m∠O+m∠L=
Step 
Find the value of x
Step 
Find the value of angle L
m∠L
m∠L
m∠L
Remember that
m∠N=m∠L
m∠N=
therefore
the answer is
the measure of the angle N is equal to
Solve for x over the real numbers:
x^4 - 17 x^2 + 16 = 0
Substitute y = x^2:
y^2 - 17 y + 16 = 0
The left hand side factors into a product with two terms:
(y - 16) (y - 1) = 0
Split into two equations:
y - 16 = 0 or y - 1 = 0
Add 16 to both sides:
y = 16 or y - 1 = 0
Substitute back for y = x^2:
x^2 = 16 or y - 1 = 0
Take the square root of both sides:
x = 4 or x = -4 or y - 1 = 0
Add 1 to both sides:
x = 4 or x = -4 or y = 1
Substitute back for y = x^2:
x = 4 or x = -4 or x^2 = 1
Take the square root of both sides:
Answer: x = 4 or x = -4 or x = 1 or x = -1

The given expressions above are examples of an absolute-value inequality. In the expression |a – 8| ≤ 3, this is equal to -3 ≤ a - 8 ≤ 3. In this case, the answer here in 1 is A. a – 8 ≤ 3 and a – 8 ≥ –3. in 2, the expression is 4 – 2(n + 6) ≥ 2 or -8 -2n ≥ 2 or 4 + n ≤ -1 equal to n ≤ -5. The other equation is 4 – 2*-(n + 6) ≥ 2. 16 + 2n ≥ 2 or 8 + n ≥ 1. n ≥ -7. Answer is n ≤ -5 or n ≥ -7 .The equation |k + 6| = 3 is equal to <span>k + 6 = 3 or k =-3 and k+6 =-3 equal to k = -9. Answer in 3 is C. </span>
