Solve for x in the equation x2 + 20x+100= 36.
Answer:
-16, -4
Step-by-step explanation:
x² +20x +100 -36 = 0
x² +20x +64 = 0
x² -Sx +P =0, where S= sum of roots, P=product of roots
so what 2 numbers have
S= -20 and P = 64 , ...that ul be -4, -16
or you can use factoring:
( x+16) ( x+4) = 0
x+16 = 0 , x= -16
x+4 =0, x = -4
or you can do quadratic equation, or graph ...
Answer: The Answer is:
Fraction form: x= -32/11
Decimal form: x= -2.90909....
Step-by-step explanation:
1. Add similar elements: 2x+20x=22x
22x+100=36
2. Subtract 100 from both sides:
22x+100-100=36-100
3. Simplify:
22x=-64
4. Divide both sides by 22:
22x÷22=-64÷22
5. Your Answer:
x= -32/11

m = 1/2
Formula
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = 5
x2 = x
x1 = 2
1/2 = (3 - 5)/(x - 2) Cross multiply
1*(x - 2) = 2 (-2) Combine and remove the brackets.
x - 2 = - 4 Add 2 to both sides
x = - 4 + 2
x = - 2

Megan ran 9/12 of a mile and skips a 12th of a mile around the track how far around the track did Megan go in total use the benchmarks fraction 1/2 1 and 0 to help you estimate each answer before you solve
Answer:
She went a total of 5/6 of a mile around the track
Step-by-step explanation:
Here, we want to calculate the distance around the track travelled
From the question, we are told that she ran 9/12 of a mile and skipped 1/12
So the total distance covered will be;
9/12 + 1/12 = 10/12 = 5/6
A builder is building a fence with 6 LaTeX: \frac{1}{4}1 4 inch-wide wooden boards, arranged side-by-side with no gaps. How many boards are needed to build a fence that is 150 inches long?
Answer:
24 boards
Step-by-step explanation:
From the above question, the width of a wooden board for a fence = 6 1/4 inches
How many boards are needed to build a fence that is 150 inches long?
This is calculated as:
6 1/4 inches = 1 board
150 inches = x
Cross Multiply
6 1/4 × x = 150 × 1
x = 150 ÷ 6 1/4
x = 150 ÷ 25/4
x = 150 × 4/25
x = 24 boards
Hence, 24 boards would be needed to build a fence that is 150 inches long

A wireless company offers two cell phone plans. For the month of September Plan A charges $35 plus $0.25 per minute for calls. Plan B charges $20 plus $0.50 per minute for calls. For what number of minutes do both plans cost the same amount?
i really need help
Answer:
3.75 minutes
Step-by-step explanation:
Set up an equation where x is the number of minutes:
0.25x + 35 = 0.5x + 20
Solve for x:
0.25x + 35 = 0.5x + 20
35 = 0.25x + 20
15 = 0.25x
3.75 = x
So, both plans will cost the same with 3.75 minutes
What is the answer?
Answer:
B is the answer

| - 2x | = 4
The absolute value function always gives a positive result, however, the expression inside can be positive or negative , that is
- 2x = 4 or - (- 2x) = 4
Solving both
- 2x = 4 ( divide both sides by - 2 )
x = - 2
or
- (- 2x) = 4
2x = 4 ( divide both sides by 2 )
x = 2
The third graph indicates x = - 2 and x = 2 on the number line

The graph shows the amount of money left after buying video games. Find the slope of the line
Answer:
It’s -20
Step-by-step explanation:
The slope of the line is m = -20.
What is the slope?The ratio of the vertical and horizontal changes between two points on a surface or a line is known as the slope.
Note that the graph passes through points (2,80) and (4,40).
The formula for the slope of a line passing through the points (x₁,y₁) and (x₂,y₂) is:
m = (y₂-y₁)/(x₂-x₁)
Substitute the points (x₁,y₁) = (2,80) and (x₂, y₂) = (4,40) into the above equation:
m = (40 - 80)/(4 - 2)
m = -40/2
m = -20
Hence, the slope of the line is m = -20.

Give the equation for this line in
slope-intercept form.
slope = -2, y-intercept = 5
y ]
= [?]x + []
Answer:
y = -2x + 5
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. Since we already know the values, we can just put it into the equation.
y = mx + c
y = -2x + 5
Answer:
y = - 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 5 , thus
y = - 2x + 5 ← equation of line

What is the image of the point (-6,-8) after a rotation of 90° counterclockwise about the origin?
Answer:
(6,-8)
Step-by-step explanation:
By rotating the point (-6,-8) Counterclockwise you get the point (6,-8)
Hope it helps
The new coordinates after rotation will be - P'(8, -6)
We have a Point on a X - Y plane as P(-6, -8) which is rotated by 90° counter clockwise about the origin.
We have to determine the image of this point after the rotation.
What do you understand by Rotation of a Point in X - Y plane?
A rotation is a transformation in a plane that turns every point of a preimage through a specified angle and direction about a fixed point.
According to the question, we have -
A point with coordinates → P(-6, -8)
Any point (say A[x, y]) when rotated 90° counter clockwise about the origin, then its new coordinates become A'(-y, x).
Using this rule, the coordinates of the point after rotation of point by 90° counter clockwise about the origin will be → P'(8, -6)
Hence, the new coordinates will be - P'(8, -6)
