Answer:
y = 6x - 2
Step-by-step explanation:
Let the equation of the line be y = mx + c
m = (10 - (-8))/(2 - (-1)) = 6
sub (2, 10):
10 = 6(2) + c
c = -2
therefore, the equation of the line is y = 6x - 2

What is the slope of the line that contains these points?
Answer:
[tex]m=7[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Find points from chart.
Point (-7, -7)
Point (-4, 14)
Step 2: Find slope m
Substitute: [tex]m=\frac{14+7}{-4+7}[/tex]Add: [tex]m=\frac{21}{3}[/tex]Divide: [tex]m=7[/tex]Answer:
[tex]\boxed {\boxed {\sf m=7}}[/tex]
Step-by-step explanation:
To find the slope, we can use the slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line.
We can pick any two points in the chart.
Let's use (-1, 35) and (2,56).
If we use these points, then the variables are:
[tex]x_1=-1 \\y_1=35 \\x_2=2 \\y_2=56[/tex]
Substitute the values into the formula.
[tex]m=\frac{56-35}{2--1}[/tex]
Solve the numerator.
56-35=21[tex]m=\frac{21}{2--1}[/tex]
Solve the denominator.
2--1= 2+1=3[tex]m=\frac{21}{3}[/tex]
Divide.
[tex]m=7[/tex]

a square has a perimeter of 52 mm. The square is dilated by a scale factor of 3. what is the side length of the resulting image?
Answer:
39
Step-by-step explanation:
Since a square has 4 equal sides, it's safe to do [tex]\frac{52}{4}[/tex] to get each side length (each side is 13 mm).
Dilating a side means you're multiplying it by the scale factor. This means that you're doing [tex]13*3[/tex] to each side (each side is 39 mm).

The 7th grade has 220 students. Three-fifths of the students are girls. How many boys are in the 7th grade?
Answer:
88 are boys
Step-by-step explanation:
220 times 3/5 = 132
220-132 =88
The number of boys in the 7th grade is B = 88 boys
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as B
Now , the value of B is = number of boys
Substituting the values in the equation , we get
If three-fifths of the students are girls, then two-fifths must be boys, since the total fraction of students is equal to 1
On simplifying the equation , we get
To find the number of boys in the 7th grade, we can start by calculating the fraction of boys:
( 2/5 ) x 220 = 88
Hence , there are 88 boys in the 7th grade.

What’s is the rate of change for the line that goes through the points (8,14) and (11,19.25)
Answer:
Rate of Change / Slope = 1.75 (or 7/4)
Step-by-step explanation:
Slope is Rise/Run which is (y2-y1)/(x2-x1). When we plug in both ordered pairs, we get (19.25-14)/(11-8)=5.25/3=1.75 as the slope.
The rate of change is the ratio of the rise and the run of the line. Hence, the rate of change of the line is 1.75
Rate of change = (Rise / Run)Rise = y2 - y1 = (19.25 - 14) = 5.25
Run = x2 - x1 = (11 - 8) = 3
Rate of change = (5.25 / 3) = 1.75
Therefore, the rate of change for the line is 1.75

Let x and y be positive integers and x >y.
11
Complete Question:
Let x and y be positive integers and x be greater than y.
11x/11y = ?
Answer:
11x/11y = x/y
Step-by-step explanation:
Given
x > y
Required
11x/11y
From the question, we understand that x is greater than y (i.e. x > y)
Also, we'll assume that y ≠ 0, in other not to result in an undefined result.
So,
11x/11y
Divide the numerator and denominator by 11
(11x ÷ 11)/(11y ÷ 11)
The result of the division is:
(x)/(y)
x/y
Hence,
11x/11y = x/y for x > y and y ≠ 0

What is P(factor of 8)?
Write your answer as a percentage.
Answer:
50% 1/2 3/6 0.5
Step-by-step explanation:
You can either get a 1, 2, 3, 4, 5, or a 6.
The factors of 8 include 1, 2, 4, 8.
There is only a matching 1, 2, and 4, but you cannot get any more factors. There are only 3 numbers out of a possible 6 number choices, so 3/6.
3/6 can be simplified to 1/2, and as a percentage, that is 50%.

Andy and Christopher are measuring a liquid solution using graduated cylinders, Andy uses 3.5 liters of the liquid solution, and Christopher uses 2,580 milliliters of the liquid solution. What is the ratio of Christopher's measurements to Andy's measurements in milliliters? One liter equals 1,000 millilters. Simplify your answer.
Answer:
[tex]Ratio = 0.74[/tex]
Step-by-step explanation:
Represent
- Andy with A
- Christopher with C
[tex]A = 3.5L[/tex]
[tex]C = 2580mL[/tex]
Required
Determine the ratio of C to A
Ratio is represented as thus:
[tex]Ratio = C:A[/tex]
Rewrite as fraction
[tex]Ratio = \frac{C}{A}[/tex]
This gives
[tex]Ratio = \frac{2580mL}{3.5L}[/tex]
Convert L to mL
[tex]Ratio = \frac{2580mL}{3.5*1000mL}[/tex]
[tex]Ratio = \frac{2580mL}{3500mL}[/tex]
[tex]Ratio = \frac{2580}{3500}[/tex]
[tex]Ratio = 0.73714285714[/tex]
