Answer:
A and B are correct, but A is most correct.
Step-by-step explanation:
just do Pythagorean theorem and see which numbers add up to each other. if you do them for all 4 answers, you see d and c do not equal to each other. b is almost correct, and a comes out exact.
Step 1: set up equation
-2x+y=3
Step 2: add 2x to both sides
-2x+y=3
+2x +2x
<u>
y=3+2x</u>
Hope this helps :)
Answer:
{ x | x < 2 or x > 8}
Step-by-step explanation:
Given the expression
(x + 3 < 5) U (x - 7 > 1).
Solve x+3 < 5
Subtract 3 from both sides
x+3 - 3 < 5-3
x < 2
For x - 7 > 1
Add 7 to both sides
x-7+7 > 1 + 7
x > 8
Hence the union of both is { x | x < 2 or x > 8}
The correct answer is A.
Here is the completed problem:
3(4x+5)=12
Distributive property.
3(4x+5)=12
Simplify
12x+15=12
Subtract 15 from both sides.
12x+15−15=12−15
12x=−3
Divide both sides by 12.
12x/12 = −3/12
x= −1/4
