Which of the following equations represents the line that is graphed on the coordinate grid below?
y=−1/3x+ 2y=−13x+ 2
y=−1/3x−6y is equal to negative 1 third x minus 6
y=−3x+6y is equal to negative 3 x plus 6
y=−3x+2
Answer:
y = -(1/3)x + 2
Step-by-step explanation:
Keeping in mind the equation of a line: y = mx + c
Notice three discernible points on the graph: (0,2), (3,1), (6,0).
The first and last points mentioned represent the intercept on y-axis and the intercept on x-axis respectively.
Therefore, when x = 0, y = 2. And 2 = m(0) + c
c = 2
Also, when y = 0, x = 6. And 0 = 6m + 2
6m = -2. And m = -(2/6) = -(1/3)
Therefore, y = -(1/3)x + 2

Urgent help pleaseeeeeee
Answer:
2x - 10 = 10 - 3x
Simplifying
2x + -10 = 10 + -3x
Reorder the terms:
-10 + 2x = 10 + -3x
Solving
-10 + 2x = 10 + -3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4

Solve the Quadratic Equation: 2(x - 5)^2 = 18
Answer:
x=2 or x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x2−20x+50=18
Step 2: Subtract 18 from both sides.
2x2−20x+50−18=18−18
2x2−20x+32=0
Step 3: Factor left side of equation.
2(x−2)(x−8)=0
Step 4: Set factors equal to 0.
x−2=0 or x−8=0
x=2 or x=8
Answer:
1. x = 8
2. x = 2
Step-by-step explanation:
2 • (x - 5)2 - 18 = 0
2.1 Evaluate : (x-5)2 = x2-10x+25
3.1 Pull out like factors :
2x2 - 20x + 32 = 2 • (x2 - 10x + 16)
3.2 Factoring x2 - 10x + 16
The first term is, x2 its coefficient is 1 .
The middle term is, -10x its coefficient is -10 .
The last term, "the constant", is +16
Step-1 : Multiply the coefficient of the first term by the constant 1 • 16 = 16
Step-2 : Find two factors of 16 whose sum equals the coefficient of the middle term, which is -10 .
-16 + -1 = -17
-8 + -2 = -10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and -2
x2 - 8x - 2x - 16
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-8)
Add up the last 2 terms, pulling out common factors :
2 • (x-8)
Step-5 : Add up the four terms of step 4 :
(x-2) • (x-8)
Which is the desired factorization
2 • (x - 2) • (x - 8) = 0
4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

On Monday, water was pumped out of the pool at a constant rate, starting at 12:00 p.m.
At 12:15 p.m., the water in the pool was 45 inches deep.
At 12:35 p.m., the water in the pool was 41 inches deep.
Part B - Write an equation that represents y, the depth of the water (in inches), after x minutes.
Answer:
so every 20 minutes it goes down by 4 inches so 20x-4y
Step-by-step explanation:
20x-4y means every 20 minutes it goes down 4 inches
The table below shows the amount of flour and eggs you need for making different-sized batches of cookies using the same recipe.
Cups of flour Number of eggs
Batch A 3 2
Batch B 9 6
Batch C 12 8
Write an equation to describe the relationship between f, the cups of flour, and e, the number of eggs.
So to do this we have to divide cups of flour and Number of eggs.
So that means we can divide 3 / 2 = 1.5
9 / 6 = 1.5
12 / 8 = 1.5
So that means f is the cups of flour and e is the number of eggs.
So we can said we can put f / e =1.5
Cups of flour / Number of eggs = 1.5
So the answer is f / e = 1.5
f/e=1.5
Answer:
flour/eggs=1.5

Answer:
x = -16[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
When there are two lines that intersect at one point, the two angles that are directly opposite each other are equal. So in this case, (6x+175) = (3x + 127)
6x + 175 = 3x + 125
6x - 3x = 125 - 175
3x = -50
x = -50 ÷ 3
x = -16[tex]\frac{2}{3}[/tex]
3x + 127 = 6x + 175 (Since its an opposite angle)
3x = 48
x = 16

Liam walked from his house to the school in 17 minutes. He arrived at the school at 7:50 a.m. Stephanie started walking 5 minutes after Liam left his house. She arrived at the school at 7:52 a.m. How long did it take Stephanie to walk to the school?
Answer:
14 minutes
Step-by-step explanation:
If Liam got to school at 7:50, and it took him 17 minutes, that means he left at 7:33. Five minutes after 7:33 is 7:38, so that's when Stephanie left. She arrived at school at 7:52 am, so what we have to do is subtract 7:38 from 7:52 in order to get 14 minutes elapsed.
