What is the equation of the line that goes through the points (1,1) and 3,-3)
Answer:
y = -2x + 3
Step-by-step explanation:
[]Let us write an equation in slope-intercept form.
-> See attached
-> Our equation will start out as y = x
[] The slope can be found by taking the change in y divided by the change in x
-> [tex]\frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2[/tex]
-> Now our equation is y = -2x
[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.
-> y = -2x + b
(1) = -2(1) + b
1 = -2 + b
3 = b
-> Now our equation is y = -2x + 3, which is our final answer.

Answer:
y = -2x +3
Step-by-step explanation:
coordinates given (1,1) and (3,-3)
How to find equation? first find slope.
slope formula:
(y2-y1)/(x2-x1)
using this formula:
(-3-1)/(3-1)
-4/2
-2 ........this is slope also refereed as (m) in short form.
Use the formula:
y - y1 = m( x - x1)
using the formula:
y - 1 = -2( x - 1)
y -1 = -2x + 2
y = -2x +3
how do i do this, my son is struggling and he needs help
Answer:
32
Step-by-step explanation:
angle a is the outside angle. It creates a circle that will always equal 360 degrees. Since the outside angle is 302, the inside angle must be 58 degrees (360-302). The top square angle will be 90 degrees (a square angle is always 90 degrees). Since the angles in a triangle always add up to 180 degrees, we need to add 58 and 90, and then subtract it from 180, which equals 32. So, angle x equals 32.
Answer:
x = 32°
Step-by-step explanation:
The triangle is 58°. I know this because the question stated that "a" is 302. A full circle is 360. So you can subtract 360 - 302 = 58. There is a small corner of a square in the other side of the triangle. With that we know that, that side has to be 90°. A triangle is 180° total. So we can subtract:
180 - 90 - 58 = 32
Therefore, x = 32°

The side of one square is 2 centimeters longer than the side of the second square. If the sum of their
areas is 100cm?, find the length of the side of each square.
*DUE TOMORROW* please help
Answer:
Side length of first square is 10 cm
Side length of second square is 8 cm
Step-by-step explanation:
Let (x + 2) = side length of first square
Let x = side length of second square
Area of a square = (side length)²
⇒ area of first square = (x + 2)²
⇒ area of second square = x²
If the sum of their areas is 100 cm² then:
⇒ (x + 2)² + x² = 100
Expand the brackets:
⇒ x² + 4x + 4 + x² = 100
Collect and combine like terms:
⇒ 2x² + 4x + 4 = 100
Subtract 100 from both sides:
⇒ 2x² + 4x - 96 = 0
Divide both sides by 2:
⇒ x² + 2x - 48 = 0
Factor:
⇒ (x - 6)(x + 8) = 0
Therefore,
⇒ x = 6, x = -8
As distance is positive, x = 8 only.
Therefore, side length of first square is 10 cm
Side length of second square is 8 cm

Which ordered pair can be added to the table so that y is still a function of x
A. 4,5

The number that gives a value of 25 when 1/4 of the number is added to 4 is 80.
What is the number?The first step is to represent the information in the question as an equation:
1/4x + 5 = 25
In order to determine the number, take the following steps:
Combine similar terms
1/4x = 25 - 5
Add similar terms
1/4x = 20
Multiply both sides of the equation by 2
x = 80

what is the perimeter of an equilateral triangle whose height is 2 square root of 3
Answer:
the answer for this is 12
Answer:
Step-by-step explanation:
If we half the base of the equilateral triangle, which has a length of xcm, we can form a right-angled triangle with a base of x/2 cm and height 2√3 cm.
Now using Pythagoras' Theorem we solve for the hypotenuse:
[tex]x^{2} = (\frac{x}{2})^{2} + (2\sqrt{3})^{2}\\ x^{2} = \frac{x^{2}}{4} + 12\\ 4x^{2} = x^{2} + 48\\ 3x^{2} = 48\\ x^{2} = 16\\x = \frac{+}{}4\\ \\[/tex]
x must be positive as it is a length so we multiply 4 by 3 to get the perimeter of 12.

1. Chef Alfredo has noticed some changes in his business. He usually sells 45 pizzas on Sunday afternoons. During
football season, he has big television screens televising NFL games and he sells 72 pizzas.
a. What is the percent change?
b. did it increase or decrease?
c. answer in a complete question
(PLEASE SHOW WORK)
Answer:
a. 60%
b. increase
Step-by-step explanation:
To find the percentage, you can divide 72 by 45 to get the decimal increase, or 1.6. Percentage rates are decimals, and you can think about this like coloring 60 circles out of 100, representing 60% of 100. Since 72 is higher than 45, this was a percentage increase.
