(m*-2)*5 simplifies to m*-10.

This is because when you have a number with an exponent to an exponent, you multiply the exponents.

$(m^{-2})^5=m^{-2\cdot5}=m^{-10}$

$x^2+3x-10=\\
x^2+5x-2x-10=\\
x(x+5)-2(x+5)=\\
(x-2)(x+5)$

Answer:

Part A) The percentage increase was $6.1\%$

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

$\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%$

Part B) Compare the percentage increase with the inflation

$6.1\%>5\%$

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

Answer:

1. y ax

|
A-------------------------------B

------------C---------------------

|__________________x ax

for this, your A might be (0,5), B (5,5), C (2,2).

parallel means railroad tracks: same slope, different intercepts.

line AB in this case has a slope of 0, intercept (0,5), so y₁=0x+5 or just y₁=5

the line passing through C also has slope 0, but intercept (0,2), so y₂=0x+2 or just y₂=2

2. perpendicular means that the slopes of two lines multiply out to -1. If line AB has, for example, a slope of 2/3, then the line passing through C would have slope -3/2 (negative reciprocal). To make things easier have either point A or B be on the x or y axis
