Answer:

Step-by-step explanation:

y=mx + b is easier to solve for when you need to find slope intercept form. If you have your y and mx you can figure out what your b is.

The graph shows a reflection in the x-axis. The matrix M such that, for any point (x, y), M(x, y) = (x', y') is
Rashid [163]

Answer:

This is a reflection about the x-axis.


Step-by-step explanation:

A reflection about the x-axis has the rule

[x,y]-> [x,-y].

Therefore

M[x,y] = [x,-y}

Let M=

|a  b|

|c  d|

Then the matrix multiplication gives

ax+by=x.............(1)

cx+dy=-y............(2)

Solving the previous equations (1) and (2) gives

a=1, b=0

c=0, d=-1

giving M as

|1  0|

|0 -1|

What is a simple rule for adding and subtracting like fractions
konstantin123 [22]

Here is you're answer:

One of the most simple rules when solving fractions is to "find the common denominator."

Example:

  • \frac{1}{2} + \frac{1}{2} =
  • Find the common denominator:
  • Common denominator is 2:
  • 1 +1=2
  • = \frac{2}{2} = 2

So, in order to solve fractions you first have to find the common denominator of each fraction, then you have to add or subtract the numerators to equal you're answer.

Hope this helps!

Which of the following graphs shows the solution for the inequality. y-4>2(x+2)
Crazy boy [7]

Answer:

C.

Step-by-step explanation:

First, isolate the y:

y-4>2(x+2)

y-4>2x+4

y>2x+8

First, since there is no "equal to", we can ignore B and D since their lines are shaded.

Since the y is greater than, we need to pick the graph that is shaded above the line.

The answer is C as the shaded portion is above the graph and the graph is dotted.
