How do you write the equation in slope intercept form given (2,2) and (0,-2)?
Answer:
y = 2x - 2
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b
where m is the slope, and b is the y-intercept.
y = mx + b
First we find the slope, m.
slope = (difference in y)/(difference in x)
It does not make a difference which point is first and which point is second in finding the differences, but you must do the x- and y-differences in the same order.
slope = (-2 - 2)/(0 - 2) = -4/(-2) = 2
The slope is 2, so m = 2, and now we have:
y = 2x + b
We need to find the value of b, the y-intercept.
We use one of the given points. Let's use (2, 2). We plug in 2 for x and 2 for y and solve for b.
2 = 2(2) + b
2 = 4 + b
-2 = b
b = -2
Now that we know the y-intercept is -2, we substitute b with -2.
y = 2x + b
y = 2x - 2
Answer: y = 2x - 2

Subtract (r - 3q + 5p) - (-4r - 3q - 8p)
Answer: ok so Let's simplify step-by-step.
r−3q+5p−(−4r−3q−8p)
Distribute the Negative Sign:
=r−3q+5p+−1(−4r−3q−8p)
=r+−3q+5p+−1(−4r)+−1(−3q)+−1(−8p)
=r+−3q+5p+4r+3q+8p
Combine Like Terms:
=r+−3q+5p+4r+3q+8p
=(5p+8p)+(−3q+3q)+(r+4r)
=13p+5r
Step-by-step explanation:
Answer:
5r + 13p
Step-by-step explanation:
In this question, you would simplify the expression.
Solve:
(r - 3q + 5p) - (-4r - 3q - 8p)
Use the distributive property to distribute the negative to the variables inside the parenthesis.
r - 3q + 5p + 4r + 3q + 8p
Combine like terms.
r - 3q + 5p + 4r + 3q + 8p
5r - 3q + 5p + 3q + 8p
5r + 5p + 8p
5r + 13p
Since we can't simplify further, your final answer would be 5r + 13p

If two angles are complements, then they are both acute. Which is the hypothesis?
Answer:
the hypothesis is "two angles are complements"
Step-by-step explanation:
In the given statement, the hypothesis is "two angles are complements".. While the conclusion is that "they are both acute".
The hypothesis of the two angles being complements is what led to the conclusion that they are both acute since sum of 2 complementary angles is 90° and acute angle is any angle that measures less than 90°.
What percent of the surface area of the ottoman is green not including the bottom .The radius of the ottoman is 22 in and the cushion is 6 in and the green is 10 in
Answer:
37%
Step-by-step explanation:
Surface area of a cylinder = πr² + 2πrh
With r = 22 and h = (6 + 10) = 16
Area = π * 22² + 2 * π * 22 * 16
Area = 1520.728 + 2211.968
Area = 3732.696 in²
Percentage of green = surface area of green ÷ total surface area
Surface area of green = 2πrh
Surface area of green = 2 * π * 22 * 10
Surface area of green = 1382.48
Percentage of green = 1382.48 / 3732.696 * 100%
Percentage of green = 37%

Which of the following is equivalent to 4x - 3y = 12 ?
y = -4/3x - 4
y = 4/3x + 4
y = -4/3x + 4
y = 4/3x - 4
Answer:
y = 4/3 x - 4
Step-by-step explanation:
The slope-intercept form of the equation of a line
The equation of a line can be expressed in several forms. One of them is the slope-intercept form:
y = mx + b
Where
m = slope
b = y-intercept
We are required to convert the equation of the line:
4x - 3y = 12
It can be done by solving for y.
Subtracting 4x:
- 3y = - 4x + 12
Dividing by -3;
y = 4/3 x - 4

Find value of x and y
Answer:
x = 60
y = 80
Step-by-step explanation:
x° + 120° = 180° (interior angles on the same side of transversal)
x° = 180° - 120°
x° = 60°
x = 60
x° + y° = 140° (alternate angles)
60° + y° = 140°
y° = 140° - 60°
y° = 80°
y = 80
The measure of angle ∠x is 60° and ∠y is 80°.
What are Alternate Interior Angles?Alternate Interior Angles is defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.
Since angle ∠x and ∠120° are interior angles on the same side of transversal.
So, x° + 120° = 180°
x° = 180° - 120°
x° = 60°
x = 60
Since angle ∠x° and angle ∠y° are alternate angles
So, x° + y° = 140°
Substitute the value of x = 60 in above equation,
60° + y° = 140°
y° = 140° - 60°
y° = 80°
Hence, the measure of angle ∠x is 60° and ∠y is 80°.

let 2 number be x and y
x + y = 36 ---- equation ( 1 )
x - y = 10 -----equation ( 2 )
from ( 1 ) and ( 2 )
2y = 26
y = 13
putting value of Y in equation ( 1 )
x + y = 36
x + 13 = 36
x = 36 - 13
