Answer: x^2 - y ^2 − 1.5x + 1.5y
Step-by-step explanation:
Y = 3x + 4
y = -x - 4
3x + 4 = -x - 4
3x + x = -4 - 4
4x = -8
x = -8/4
x = -2
y = 3x + 4
y = 3(-2) + 4
y = -6 + 4
y = -2
solution is (-2,-2) <==
Answer: option c or 3 because you gotta take out the 6 so u do -6 which left is negative and right is positive and then get rid of the +2 exponent so up is positive and down is negative so you move -2 which is down.
Step-by-step explanation:
The second one is correct
Answer:
Option D, 15 and 10
Step-by-step explanation:
<u>Step 1: Convert the words into an expression</u>
A number is 5 less than 2 times another number. Their sum is 25.
<em>2x - 5 = 25</em>
<em />
<u>Step 2: Solve for x</u>
2x - 5 + 5 = 25 + 5
2x / 2 = 30 / 2
<em>x = 15</em>
