Answer:.
Step-by-step explanation:.
Expand
add 5x to both sides
simplify 2x + 8 + 5x to 7x + 8
subtract 8 from both sides
simplify 1 - 8 to -7
divide both sides by 7
Answer: x = -1.
Answer:
x=1/3
Step-by-step explanation:
5=4+3x
5=3x+4 (Simplify both sides of the equation)
3x+4=5 (Flip the equation)
3x+4−4=5−4 (Subtract 4 from both sides)
3x=1
3x/3=1/3 (Divide both sides by 3)
x=1/3
Answer:
4th choice (if we guessed the blurry letters properly)
Step-by-step explanation:
The reflection maps ...
(x, y) ⇒ (x -y)
Then the rotation maps ...
(x, -y) ⇒ (y, x)
That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.
Answer:
Step-by-step explanation:
Let the larger integer = 2x + 1
Let the second integer = 2x - 1
1/2 (2x + 1 + 2x - 1) = - 12 Combine the left
1/2(4x) = - 12 Combine 1/2 (4x)
2x = - 12 Divide by 2
2x/2 = - 12/2
x = - 6
2x + 1 = 2*-6 + 1 = -11
2x - 1 = 2*-6 - 1 = - 13
Check
-11 + - 13 = - 24
1/2(-24) = -12 which checks.
