Step-by-step explanation:
<u>Step 1: Define Equation</u>
m - 4m = -6
<u>Step 2: Solve for </u><em><u>m</u></em>
- Combine like terms: -3m = -6
- Divide -3 on both sides: m = 2
<u>Step 3: Check</u>
<em>Plug in m into the original equation to verify it's a solution.</em>
- Substitute in <em>m</em>: 2 - 4(2) = -6
- Multiply: 2 - 8 = -6
- Subtract: -6 = -6
Here we see that -6 does indeed equal -6.
∴ m = 2 is the solution to the equation.
Answer:
x = 1/8
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Should be B because the slope is 2
Answer:
C
Step-by-step explanation:
It is C because the 2 is attached to the variable Y
Answer:
While x = -7 and y = 4, x² - 3xy = 133.
Step-by-step explanation:
x² - 3xy
Substitute variables.
(-7)² - 3(-7)(4)
Square -7 remembering that (-x)² = x².
49 - 3(-7)(4)
Multiply -7 and 4.
49 - 3(-28)
Multiply -3 and -28.
49 + 84
Add 49 and 84.
133
