Answer:
y = 1/4x-1
Step-by-step explanation:
Ok first, you need to find the slope:
0+2 = 2=1
4+4 = 8=4
Slope: 1/4
y=1/4x+b
Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.
I will use (4,0)
0=1/4 X 4 + b
0=x+b
minus x on both sides. x=1
-1=b
An equation of the line that passes through the pair of points
(- 4, - 2), (4, 0) is y + 2 = (1/4)(x + 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line that passes through the pair of points. (−4, −2), (4, 0).
We also know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (0 + 2)/(4 + 4) = 1/4.
So, the equation of a line in point-slope form is y - y₁ = m(x - x₁).
∴ y + 2 = (1/4)(x + 4).

Mrs. Pitoya has 30 apples and is buying more apples in crates containing 20 apples each. She needs 130 apples for a harvest celebration at her school,
Which equation and solution correctly represent x, the number of crates of apples Mrs. Pitoya needs to buy?
Answer:
Mrs pitoya has to buy 9 crates of apples
Answer: She only needs to buy 5 more crates of apples.
30 + 20(x) = 130
30-30+20(x)=130-30
20x = 100
x = 5

9,-81, 729,-6561...
What is the common ratio?
Help which is the correct answer?
Answer:
[tex]r = -9[/tex]
Step-by-step explanation:
Given
[tex]Sequence: 9,-81, 729,-6561...[/tex]
Required
Determine the common ratio
The common ratio r is calculated using:
[tex]r = \frac{T_n}{T_{n-1}}[/tex]
Let [tex]n = 2[/tex]
So, we have:
[tex]r = \frac{T_2}{T_{2-1}}[/tex]
[tex]r = \frac{T_2}{T_1}[/tex]
From the sequence:
[tex]T_2 = -81[/tex]
[tex]T_1=9[/tex]
So, the equation becomes
[tex]r = \frac{-81}{9}[/tex]
[tex]r = -9[/tex]

4. The band at Jason's high school had a concert for charity. They raised $15000. Adult tickets were $5 each and student tickets were $3 each. The members of the band sold a total of 4000 tickets. Which of the following systems of equations can be used to determine how many adult, x, and student tickets, y. they sold? A. x + y = 4000 5x + 3y = 15000 C. x - y = 4000 5x - 3y = 15000 B. x + y = 15000 5x + 3y = 4000 D. 5x + 3y = 4000 3x + 5y = 15000 03 PO P MINE W 1 NY 19 C
Answer:
A. x + y = 4000
5x + 3y = 15000
Step-by-step explanation:
Total amount raised = $15000
cost of adult tickets = $5
cost of student tickets = $3
Total number of tickets sold = 4000
number of adult tickets sold = x
number of student tickets sold = y
Then we can say,
total number of ticket sold = number of adult tickets + number of student tickets
4000 = x + y
⇒ x + y = 4000 ............. 1
Also,
5x + 3y - 15000 ............. 2
the equations required are:
x + y = 4000
5x + 3y - 15000

Answer:
1.a and 2.b.
Step-by-step explanation: let's say the area=2. if you multiply by 2, it gets bigger. if d<1, it's like dividing by a number, meaning that the area becomes smaller.
Answer:
1. a
2. b
Step-by-step explanation:
1. If d is greater than one (d>1), then that means that the shape will be dilated outward, or expanded because the number is larger than the unit of 1.
2. Multiplying the coordinates by a fraction that is less than one (0<d<1) makes the shape smaller, because fractions are smaller than the unit of 1.
Twenty people attended a going away party for Zach.The guest left in groups of 2.By 9:00,x groups had left.Rewrite the number of guests remaining at 9:00 as a sum.
Answer:
The number of guests remaining at 9:00 is;
(20-2x)
Step-by-step explanation:
From the question, we are told that x groups have left
Since they are leaving in groups of 2, x groups means a total of x * 2 = 2x
So we have 2x left out of a total 20; the people remaining at the party will be;
20-2x

Classify the quadrilateral then find the values of the variable (s) PLS HELPPP
Answer:
x = 58°, y = 32°
Step-by-step explanation:
all sides are equal, hence it is a rhombus.
in a rhombus, diagonals meet at 90degree..
hence in triangle,
58 + 90 + z = 180 (asp of a triangle.)
z = 32
y = z ( alternate interior angles as lines are parallel in rhombus)
y = 32
in the bigger triangle,
angles opposite to equal sides are equal, hence,
32 + 32 + (58 + x) = 180 ( angle sum property of a triangle,)
hence, x = 58
therefore,
x = 58°, y = 32°
What is the common ratio of 9, 81, 729. -6561
Given:
Consider the given sequence is 9, 81, 729, 6561.
To find:
The common ratio.
Solution:
We have,
9, 81, 729, 6561
Here,
First term = 9
Second term = 81
Divide the second term by first term to get the common ratio.
[tex]r=\dfrac{81}{9}[/tex]
[tex]r=9[/tex]
Similarly,
[tex]\dfrac{81}{9}=\dfrac{729}{81}=\dfrac{6561}{729}=9=r[/tex]
Therefore, the common ratio is 9.

First gets brainly
I'm not going to do all of them for you but I'm basically going to teach you what your teacher taught you.
In division with fractions, the second fraction will be flipped around and then you'll multiply normally.
Example:
(5/3)/(2/3)
You would flip around the 2/3 so it would be 3/2
Then you would multiply:
5/3*3/2
To do multiplication, multiply the top numerator by the top numerator and the bottom numerator by the bottom numerator as I'm sure you've already learned
5*3 = 15
3*2 = 6
15/6
