Because the answers are all in standard form, we can simply look for the intercepts of the graph.
x-int = (-6, 0)
y-int = (0, -2)
You must multiply these numbers by a coefficient to equal 12:
Solve both equations by dividing by their values:
Look for the answer with these coefficients. The answer is
-6x - 2y = 12.
Answer: $14.05 for 5 pounds of Turkey and $ 2.92 for 3/4 pounds of cheese.
so just in case you need this together it would be a total of $16.97.
i hope this helps you also i hope this is correct.
We are have a system of equations with 2 variables, x and y
Equation 1: -3x-3y = 3
Equation 2: y = -5x-17
For equation 1, the y is by itself on one side of the equation, so it is really easily to substitute it into equation 2. In general, to solve for system of equations, you either do elimination or substitution. You just have to find which is easier for this situation.
By substituting y for -5x-17 in equation 1, there is only 1 variable which we can solve for.
-3x-(-5x-17) = 3
Distribute negative sign to (-5x-17) Avoid the common error of forgetting!
-3x+5x+17 = 3
Combine like terms- same variables are like terms (ex. 4x and 29x) and all constants are like terms (ex. 7 and 189 )
2x+17 = 3
Subtract 17 from both sides so all the variables are on one side and the constants on the other
2x = -14
Divide both sides by 2 to isolate the x
x = -7
We now know that x = -7 so we need to plug it into an equation to solve for y
Equation 2: y = -5x-17
y = -5 (-7) -17
y = 18
Now we know that x = -7 and y = 8
We can write it as (-7, 8)
Answer:
<h2>( 7a - 2b ) ( 3x - 5y )</h2>
<u>Step-by-step explanation:</u>
21ax + 10by - 35ay - 6bx
21ax - 35ay - 6bx + 10by
7a ( 3x - 5y ) - 2b ( 3x - 5y )
( 7a - 2b ) ( 3x - 5y )
Yep..Tell me what do you wanna solve!?
