Combine like terms
-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer
hope this helps
The slope of the first equation is -2, you can see it right off.
the slope of the second equation is 2, notice both are in slope-intercept form.
both equations are the equations of a line, so is really just two lines.
because their slope differs, they're not parallel or equivalent, therefore, they lines do meet at some point, and one point only, and therefore, they have 1 solution only.
a system of equations with at least 1 solution, is a consistent system.
a consistent system with exactly 1 solution only, is not just consistent, but also independent.
Answer:
x=10.5
Step-by-step explanation:
To solve, cross multiply
7/6=x/9
6*x=7*9
6x=63
Divide by 6 on both sides
x=10.5
Another way to solve is to multiply both sides by 9
7/6=x/9
9*7/6=x/9*9
10.5=x
Hope this helps! :)
This is a conditional: if the <em>condition</em> A is satisfied (true), then the result B is also satisfied (true).
