For each value of n your going to plug that number back into the original equation.

8. square root of (1)^2 +1 which will give you 2.
9. square root of (4)^2 +4 which will give you 8.
10. square root of (16)^2 +16 which will give you 33.

Answer:

14.4c

Step-by-step explanation:

.6cm\times 24c{m}^{2}

.6cm×24cm

. 6cm 24cm^2

1 Take out the constants.

(.6\times 24)ccm{m}^{2}

(.6×24)ccmm

2 Simplify .6\times 24.6×24 to 14.414.4.

14.4ccm{m}^{2}

14.4ccmm

3 Use Product Rule: {x}^{a}{x}^{b}={x}^{a+b}x

a+b

14.4{c}^{1+1}{m}^{1+2}

14.4c

1+1

1+2

4 Simplify 1+11+1 to 22.

14.4{c}^{2}{m}^{1+2}

14.4c

1+2

5 Simplify 1+21+2 to 33.

14.4{c}^{2}{m}^{3}

14.4c

Answer:

A. (1, -4)

Step-by-step explanation:

You can try the answers to see which works. (The first one does.)

Or, you can solve the equations algebraically. Equating y-values works well here:

2x -6 = -2x -2

4x = 4 . . . . . . . add 2x+6 to both sides; next divide by 4

x = 1 . . . . . . . . shows you selection A is correct

A graphing calculator can show you the point of intersection. Perhaps this is the way to go, since the unit seems to be on graphing systems of equations. Both of these equations are in slope-intercept form (y=mx+b), so are easily graphed by starting from the y-intercept (b) and using the slope (m=rise/run) to find another point on the line.
