Answer:
y = 2x + 4
Step-by-step explanation:
the line intersects the y axis at 4. so, b = 4
For the slope, to make it really easy, you can find a point where the line is on a point purfectly and just count how many times you went up or down and then left or right. Or, you can pick 2points and use the slope formula (y2-y1)/(x2-x1). the slope is 2.

Two skaters are practicing at the same time on the same rink. A coordinate grid is superimposed on the ice. One skater follows the path y = −2x + 32, while the other skater follows the curve y = −2x2 + 18x. Find all points where they might collide if they are not careful.
Answers
Answer:
The skaters will collide at the points;
(2,28) and (4,24)
Step-by-step explanation:
The points they might collide will be the points when both y are equal;
-2x + 32 = -2x^2 + 18x
2x^2 -18x -2x + 32 = 0
2x^2 -20x + 32 = 0
2x^2 - 16x - 4x + 32 = 0
2x(x -8) -4( x -8) = 0
(2x -4)(x -8) = 0
2x = 4 or x = 8
x = 4/2 or x = 8
hence; x = 2 or 8
Now let’s get the y value
at x = 2, just substitute into any of the 2
y = -2x + 32
y = -2(2) + 32
y = -4 + 32 = 28
at x = 4
y = -2(4) + 32
y = -8 + 32
y = 24
The points that they will collide are;
(2,28) and (4,24)
Answer:
They will collide at (2,28),(8,16)

Answers
Answer:

Step-by-step explanation:
4/3-1=2
3+1/2=2
First, You cross multiply.
(x - 1)(x + 1) = 8
x^2 - 1 = 8
Now subtract 8 from both sides.
x^2 - 9 = 0
x^2 - 9 is a difference between 2 squares.
(x + 3)(x - 3) = 0
For an equation with only multiplying to be equal to 0, one of its factors must be 0.
So either x + 3 = 0 or x - 3 = 0.
So x could be -3 or 3.
The answer is (E).

Jacinth is 4 years older than her sister Naomi. The sum of their ages is 30. How old are the sisters?
Answers
Answer:
Jacinth = 17
Naomi = 13
Step-by-step explanation:
they add up to 30 and follow the criteria
Jacinth is 17 years old, and Naomi is 13 years old as per the linear equation method.
Let's assume Naomi's age is x. According to the given information, Jacinth is 4 years older than Naomi, so Jacinth's age would be x + 4.
The sum of their ages is given as 30, so we can write the equation: x + (x + 4) = 30.
Combining like terms, we have 2x + 4 = 30.
Subtracting 4 from both sides, we get 2x = 26.
Dividing both sides by 2, we find x = 13.
Therefore, Naomi's age (x) is 13 years old.
To find Jacinth's age, we substitute the value of x into the equation for Jacinth's age: Jacinth's age = x + 4 = 13 + 4 = 17 years old.
So, Jacinth is 17 years old, and Naomi is 13 years old.

Which of the following equations could represent
the points in the table? Select all that apply.
A y − 11 = −6(x − 0)
B y − 1 = −6(x + 5)
C y + 1 = −6(x − 2)
D y − 7 = −6(x − 3)
Answers
Answer:
A) y - 11 = -6(x - 0)
C) y + 1 = -6(x - 2)
Step-by-step explanation:
Plug in the corresponding x- and y- values in the table into the equations given in the answer choices.
I am going to use (1, 5) from the table.
A) y - 11 = -6(x - 0)[tex](5)-11=-6((1)-0)[/tex][tex]-6=-6(1)[/tex][tex]-6=-6[/tex]-6 DOES equal 6, so this equation could represent the points in the table.
B) y - 1 = -6(x + 5)[tex](5)-1=-6((1)+5)[/tex][tex]4=-6(6)[/tex][tex]4 \not=-36[/tex]4 does NOT equal 36, so this equation could not represent the points in the table.
C) y + 1 = -6(x - 2)[tex](5)+1=-6((1)-2)[/tex][tex]6=-6(-1)[/tex][tex]6=6[/tex]6 DOES equal 6, so this equation could represent the points in the table.
D) y - 7 = -6(x - 3)[tex](5)-7=-6((1)-3)[/tex][tex]-2=-6(-2)[/tex][tex]-2\not=12[/tex]-2 does NOT equal 12, so this equation could not represent the points in the table.
The only two equations that could represent the points in the table are answer choices A) y - 11 = -6(x - 0) and C) y + 1 = -6(x - 2).

where m represents the slope and b, the y-intercept.
−3 y = −2 x + 5
divide all terms by - 3
−3 y − 3 = − 2 − 3 x + 5 − 3

b. Find the length of KI. [Respond Here]
Answers
Answer:
a). x = 6
b). Length of KI = 20 units
Step-by-step explanation:
From the picture attached,
a). Length of KI = length of KJ + length of JI
By substituting lengths of the segments given in the picture,
(2x + 8) = 8 + (x + 6)
2x + 8 = x + 14
2x - x = 14 - 8
x = 6
b). Length of KI = (2x + 8)
By substituting x = 6 in the expression,
Length of KI = 2(6) + 8
= 12 + 8
= 20 units

Given is that the length of Yvette's cell phone screen is 0.35 feet. A movie theater screen is about 100 times longer than Yvette's cell phone screen.
Scale factor is defined as the ratio of final dimensions to the initial dimensions of the given image.
Mathematically, we can write -
{K} = final dimensions/initial dimensions
In the question given, the scale factor is -{K} = 100.
Assume the length of the movie theater to be {x}. So, we can write -
{x} = 0.35 x 100
{x} = 35/100 x 100
{x} = 35 feet
Therefore, the length of the movie theater will be 35 feet.
