Answer:

11x - 10

Step-by-step explanation:

because there is a plus sign between the brackets, we just assume there are no brackets at all........so it will be:

9x - 2 + 2x - 8,,,,,,,,,bring the like terms together

9x + 2x - 2 - 8 = 11x -10.

the answer has a minus sign because when working out two negative numbers, we add them but still maintain the negative sign.

NOTE: If the sign between the brackets was a minus , the sign in the second expression would have changed from -8 to +8

Please help! <br><br> Solve for M.<br> R=9/5M+21

ElenaW [278]

Answer:

The answer should be M = 5/9(R - 21)

Step-by-step explanation:

To find this value, follow the order of operations to isolate M.

R = 9/5M + 21

R - 21 = 9/5M

5/9(R - 21) = M

Find the value of x so that the function has the given value. f(x) = 6x + 9; f(x) = 21

Olin [163]

Answer:

$x = 2$

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

$f(x)=21\\\\ f(x)= 6x + 9$

Now , for finding x ,

$6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2$

A set of equations is given below

Alex_Xolod [135]

Answer:

No solution

Step-by-step explanation:

This is no solution due to the fact that the slope of both of the equation are the same. So they are parallel. If the b value is the same then it is infinitely many solutions. Due to the fact that the b value is not the same they are a set of parallel line. Parallel line do not touch or intersect ever so there for this is a no solution set.
