G(h(x)) = 2(3x+7) - 5
= 6x + 14 - 5
= 6x + 9
Answer:
A, C, and E good luck
Step-by-step explanation:
<u>Answer:</u> x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
<h3>
Substitute -7/5 for y in x - 2y = 3:</h3><h3>
x - 2 (-7/5) = 3</h3><h3>
x + 14/5 = 3</h3><h3>
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)</h3><h3>
x = 1/5</h3><h3><u>
Answer: </u></h3><h3>x = 1/5 and y = -7/5</h3><h3 /><h3 /><h3 />

Answer:
x = 9 or x = 0
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 4 x - 5 x = 0
x^2 - 4 x - 5 x = x^2 - 9 x:
x^2 - 9 x = 0
Factor x from the left hand side:
x (x - 9) = 0
Split into two equations:
x - 9 = 0 or x = 0
Add 9 to both sides:
Answer: x = 9 or x = 0
