Point (1, -20)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [Slope Formula]: [tex]\displaystyle m=\frac{-20+20}{1-2}[/tex][Fraction] Subtract/Add: [tex]\displaystyle m=\frac{0}{-1}[/tex][Fraction] Divide: [tex]\displaystyle m=0[/tex]Answer:
(x', y') =(2, - 20)
(x",y") =(1, - 20)
slope = y"-y'/x" - x'
= - 20-(-20)/1-2

5 times a number increased by 2 is the
same as 8 more than 3 times the number.
Find the number.
Answer:
Step-by-step explanation: 5*x + 2 = 3*x + 8
5x - 3x = 8 - 2. Which yields. 2x = 6. Therefore, x = 3. QED
Does the point (4, 25) satisfy the equation y = 7x + –3?
Answer:
yes, point (4, 25) satisfies the equation y = 7x + –3
Step-by-step explanation:
to see if the point satisfies the equation, we need to plug in the x coordinate to get y
if y is equal to the y-coordinate, then the point satisfies the equation
if y does not equal the y-coordinate, then the point does not satisfy the equation:
y = 7(4) + - 3
y = 28 + -3
y = 25
does 25 = 25? Yes! so the point satisfied the equation
Answer:
yes
Step-by-step explanation:
7(x)- 3 = y
7(4) - 3 = (y)
28 - 3 = 25
Harry and Luna together ate 56 Chocolate Frogs. Harry ate 6 more Chocolate Frogs than Luna. How many Chocolate Frogs did Luna eat?
Answer: 25 chocolate frogs eaten by Luna
Step-by-step explanation:
let the amount of chocolate frogs eaten by Luna = x
and the amount of chocolate frogs eaten by Harry = 6+ x
Such that total a,mount of chocolate frogs eaten by both of them
= x +( 6+x) = 56
Step 2- Solving
x+6+x=56
6 + 2x= 56
2x= 56-6
2x= 50
x= 50/2
x= 25
x= 25 chocolate frogs eaten by Luna
6 +x= 6+ 25= 31 chocolate frogs eaten by Harry.

If using the method of completing the square to solve the quadratic equation x^2-13x+14=0, which number would have to be added to "complete the square"?
Answer:
169/4
Step-by-step explanation:
Take the coefficient of the x term. Here it's -13. Now halve that, obtaining -13/2. Finally, square this result. We get 169/4. This is the desired number.
x^2 - 13x + 169/4 - 169/4 + 14 = 0
find the perimeter of WXYZ
Answer:
40 but see below.
Step-by-step explanation:
You have to assume that the figure is a parallelogram. That is never a safe assumption, but you have to make it because there is nothing else you can do.
That being the case, to get the perimeter, you just add the sides. If say well y could be just about any value with some limitations, you would be correct.
Per = 12 + 12 + 8 + 8 = 40
Draw a ring around the point which does not lie on the line y = 3x + 2 * 1 point (100, 302) (2, 8) (0, 4) (9, 29)
Answer:
(0,4)
Step-by-step explanation:
Given the line equation:
y = 3x + 2
Given the points :
(100, 302)
x = 100 ; y =302
302 = 3(100) + 2
302 = 300 + 2
(2, 8)
8 = 3(2) + 2
8 = 6 + 2
(0, 4)
4 = 3(0) + 2
4 ≠ 2
(9,29)
29 = 3(9) + 2
29 = 17 + 2

What is the slope of (1,4) (7,2)
Answer:
3 or 3/1
Step-by-step explanation
the equation for finding the slope when given two coordinate pairs is (y₂ - y₁)/(x₂ - x₁), aka change in y over change in x.
pick one of your coordinate pairs to be y₂ and x₂. it doesn't matter which coordinate pair you choose. the remaining coordinate pair will be your y₁ and x₁.
for this example, i'll use the coordinate pair (7, 2) as my y₂ and x₂ and (1, 4) as my y₁ and x₁.
first, substitute the x-value and y-value from the first coordinate pair.
(y₂ - y₁)/(x₂ - x₁) ⇒ (7 - y₁)/(2 - x₂)
then substitute the y-value and x-value from the remaining coordinate pair.
(7 - y₁)/(2 - x₂) ⇒ (7 - 4)/(2 - 1)
subtract 7 - 4.
(7 - 4)/(2 - 1) ⇒ (3)/(2 - 1)
subtract 2 - 1.
(3)/(2 - 1) ⇒ (3)/(1) or 3/1
simplify.
3/1 ⇒ 3

Conserve Tree Foundation is trying to increase the number of trees in a region that has suffered deforestation. It plants a certain number of trees each year, resulting in a linear growth model, y1 = 5t, where t represents the time that has passed in years and y1 represents the number of trees planted. In the same region, the number of trees remaining, y2, is inversely proportion to the time elapsed, t. This is represented by . The graphs of the two equations are shown.
