This is written as:

21 - 2(10 - 3^2) + 4 and is an expression, not an equation.

The work inside ( ) must be done first: 21 - 2(10 - 3^2) + 4 => 21 - 2(10 - 9) + 4, and, continuing, this gives us 21 - 2 + 4. That sums up to 23 (answer).

Which point on the graph is the solution to the system of linear equations? -2x=-y+4 x=-2
Elodia [21]

Answer:

The solution is (-2, 0)

Step-by-step explanation:

Re-write -2x=-y+4 x=-2 in column form:

x=-2

-2x=-y+4

Next, substitute -2 for x in the second equation:

-2(-2) = -y + 4, or:

4 = -y + 4.  Thus, y must be 0.

The solution is (-2, 0)
