Answer:
x = 1 or x= -2
Step-by-step explanation:
You have a parabolic function or you can say quadratic function.
f(x) = x^2 + x - 2 = 0
x^2 + x + (1/4) - (1/4) - 2 = 0
(x + 1/2)^2 - 9/4 = 0
x + 1/2 = root(9/4)
x + 1/2 = 3/2
x = 1 or -2
Answer:
<h2>1 1/2</h2>
Step-by-step explanation:
<h3>
Step 1: Convert to Improper Fractions</h3>
Multiply the whole number 7 by the denominator 8.

Add the answer from previous step, 56. to the numerator 1.
56 + 1 = 57.
Write answer over the denominator 8.
For the second number:
Multiply the whole number 4 by the denominator 4.

Add the answer to the numerator 3.
16 + 3 = 19.
Write previous answer (19) over the denominator 4.
<h3>Step 2: Divide</h3>
IMPORTANT: To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

Final answer is 1 1/2
I'm always happy to help :)
Answer:
33%
Step-by-step explanation:
There were 3 students total who were assigned, this would be your denominator (n/3). If only 2 showed up, that would mean that 2/3 of those assigned attention showed up, so 67%. However, it asks for what percentage didn't, so you'd do 3/3 - 2/3, which is 1/3 (You subtract from 3/3 because there was a total of 3 assigned.) 1/3 into a percentage is 33%
Answer:

Step-by-step explanation:
Look at pic below I hope this helps! :)
The answer is (20,0). We can determine the sum of two vector points by adding x1 to x2 and y1 to y2. This is like adding integers, the only difference is the answer is in vector form. In here, we have (x,y). x = 7+13 and y = 5+(-5). that is why we have the (20,0) as the answer.
