Would you multiply M by the third equation (6x^5.....) since it is subtraction
steposvetlana [31]

Answer:

B

Step-by-step explanation:

Here, we want to get the value of m

The value of m can be obtained by multiplying the first factors of the first two polynomial, subtracting the first factor of the third and equating to 18

So what we have will be;

m * 6 - 6 = 18

6m -6 = 18

6m = 18 + 6

6m = 24

m = 24/6

m = 4

Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth.
lakkis [162]
\sf 5x+2y=21
\sf -2x+6y=-34

We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':

\sf -2x+6y=-34

Subtract 6y to both sides:

\sf -2x=-6y-34

Divide -2 to both sides:

\sf x=3y+17

Plug in 3y + 17 for 'x' in the first equation:

\sf 5x+2y=21

\sf 5(3y+17)+2y=21

Distribute 5:

\sf 15y+85+2y=21

Combine like terms:

\sf 17y+85=21

Subtract 85 to both sides:

\sf 17y=-64

Divide 17 to both sides:

\boxed{\sf y\approx -3.8}

This is the y-coordinate of the solution.

A banana bread recipe calls for 3/4 cup butter. One tablespoon equals 1/16 cup. How many tablespoons of butter are needed to mak
Korolek [52]
We're finding the equivalent value to 3/4. So 3/4 would be equal to or equivalent to 12/16. We know this because 12/16 simplified = 3/4. So since 3/4 is equal to 12/16, that means it would take us 12 tablespoons of butter to make the banana bread.  

I hope this helps! ^_^
