Solve by substition x-y=-1 3x+2y=22

x=4 and y= 5

Step-by-step explanation: 1 Solve for xx in x-y=-1x−y=−1.

x=y-1

x=y−1

2 Substitute x=y-1x=y−1 into 3x+2y=223x+2y=22.

5y-3=22

5y−3=22

3 Solve for yy in 5y-3=225y−3=22.

y=5

y=5

4 Substitute y=5y=5 into x=y-1x=y−1.

x=4

x=4

5 Therefore,

\begin{aligned}&x=4\\&y=5\end{aligned}

​

x=4

y=5

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

which expression represents the approximate length of bc?
