Answer: 3/2

Step-by-step explanation:

Let's consider the points (6,9) and (4,6).

The difference in the y coordinates is 3, and the diffeence in the x coordinates is 2.

So, the slope is 3/2.

Solve the inequality x + 2 1/2 > -1/2. Graph the solution set on a number line.show your work.

Answer:

x > - 3

Step-by-step explanation:

x + 2 $\frac{1}{2}$ > - $\frac{1}{2}$ First turn 2 $\frac{1}{2}$ into an fraction since its easier. So it becomes $\frac{5}{2}$

x + $\frac{5}{2}$ > - $\frac{1}{2}$

- $\frac{5}{2}$ - $\frac{5}{2}$ Do inverse operations, so subtract $\frac{5}{2}$ from both sides.

x > - $\frac{6}{2}$ Combine - $\frac{5}{2}$ with - $\frac{1}{2}$ , which gives us - $\frac{6}{2}$

x > - 3 Since we know that 6 divided by 2 is 3.

This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)

<-------------O--------------------------------------------------->

-5 -4 -3 -2 -1 0 1 2 3 4 5

So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.

Langle is so degrees and ove on.

andre [41]

Step-by-step explanation:

perimeter = 332

let the width be 'x'

then, length = 2x+7

perimeter = 2 (length+width)

332 = 2 ( 2x+7 + x )

332/2 = 3x + 7

166 - 7 = 3x

159/3 = x

53 = x

therefore, width (x) = 53

length = 2(53)+7

= 113

Evaluate the expression. Write your answer in scientific notation. (9×10^−3)+(2.4×10^−5)÷0.0012

Feliz [49]

This, you will have to use your calculator for, but I can still explain it.
First off, 9x10^-3 is equivalent to 0.009
Second: 2.4x10^-5 is equivalent to 0.000024
Parenthesis
Exponents
Multiple
Divide
Addition
Subtraction
PEMDAS is the order you go in always, if it's multiple or division, you do whichever one comes first, same with addition and subtracting, so left to right
FIRST: do 0.000024 / 0.0012 = 0.02
0.009 + 0.02 (answer above) = 0.29
