Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
B is answer
Answer:
use photo math
Step-by-step explanation:
The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have an inequality:
−14a ≥ 42
-a ≥ 3
a ≤ -3
a ∈ (-∞, -3]
Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

The answer to your problem is a^67b^76
To solve for y, you do not get a value as there are no values in the equation. You can however still solve, as long as you make the equation "y =". To do this, you need to get y by itself, and we can see that it is being multiplied by r. To move the r onto the other side, we therefore have to divide by r on both sides. This leaves us with y = Z/r, which is your answer.
I hope this helps!
