Answer:
See answers below
Step-by-step explanation:
Standard equation of a line is expressed as y = mx+b
m is the slope
b is the y intercept
Given the coordinate points (-2, -4) and B(1, -7)
Slope m = y2-y1/x2-x1
m = -7-(-4)/1-(-2)
m = -7+4/1+2
m = -3/3
m = -1
Get the intercept
Substitute m = -1 and (1, -7) into y = mx+b
-7 = -1(1) + b
-7 = -1 + b
b = -7+1
b = -6
Get thw equation
y = mx+b
y = -x + (-6)
y = -x - 6
Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (3, 5)
x0 = 3
y0 = 5
Given the equation y = 2x+3
mx = 2x
m = 2
slope = 2
Substitute the slope and the point in the expression
y - 5 = 2(x -3)
y - 5 = 2x - 6
y - 2x = -6 + 5
y - 2x = -1
This gives the required equation
Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (5, 7)
x0 = 5
y0 = 7
Slope = 3
Substitute the slope and the point in the expression
y - 7 = 3(x -5)
y - 7 = 3x - 15
y - 3x = -15 + 7
y - 3x = -8
This give the required equation

The length of a rectangle is 5 centimeters less than 2 times the width.
a. Write a polynomial expression that represents ( 2 points )
the area of the rectangle.Simplify the expression.
Given:
The length of a rectangle is 5 centimeters less than 2 times the width.
To find:
The polynomial expression that represents the area of the rectangle, then simplify the expression.
Solution:
Let [tex]x[/tex] be the width of the rectangle.
The length of a rectangle is 5 centimeters less than 2 times the width.
2 times the width = [tex]2x[/tex]
5 centimeters less than 2 times the width = [tex]2x-5[/tex]
Length of the rectangle = [tex]2x-5[/tex]
We know that, the area of a rectangle is:
[tex]A=length \times width[/tex]
[tex]A=(2x-5)\times x[/tex]
[tex]A=2x^2-5x[/tex]
Therefore, the required polynomial expression is [tex]A=(2x-5)\times x[/tex] and its simplified form is [tex]A=2x^2-5x[/tex].

Help! This is my math problem
Answer:
Step-by-step explanation:
The problem is that you cannot be sure that either triangle (it actually requires both of them) contain a right angle
What you have so far is SSA which is not one of the fundamental congruency triangles. In order to be certain of congruency the angle must be made up of the 2 given sides. You are certain that SAS will produce congruency. You are not so sure of r SSA. There are proofs of this on the internet. I urge you to look into it. Though not long, following it step by step takes a lot of patience. A cup of strong coffee is a good idea.

Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall. Sean's video game system measures 1 inch longer on all sides. What is the combined volume of the two game systems?
Answer:
Combined volume of the two game systems [tex]=416[/tex] cubic inches
Step-by-step explanation:
Volume of a cuboid = length × breadth × height
Soham's video game system measures 8 inches long, 6 inches wide, and 2 inches tall.
So,
Volume of Soham's video game system = 8 × 6 × 2 = [tex]96[/tex] cubic inches
As Sean's video game system measures 1 inch longer on all sides,
the video game system measures [tex]8+2=10[/tex] inches long, [tex]6+2=8[/tex] inches wide, and [tex]2+2=4[/tex] inches tall.
Volume of the video game system = 10 × 8 × 4 = [tex]320[/tex] cubic inches.
Therefore,
Combined volume of the two game systems = [tex]96+320=416[/tex] cubic inches

john simplified 2 square root of 96 to get an answer of 4 square root 24
Explain the error that john made and then correct his mistake
Answer:
Step-by-step explanation:
2√96 = 2* √(4 * 24)
= 2*2√24
= 4√24
That is equal to 2√96 but a simpler result is:
4√24 = 4 * √4*√6
= 4 *2 √6
= 8√6
