First one : y=1/3x+4.32
Second one: y=3x-2
Explanation: try Desmos. its a magical machine
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 6) and (x₂, y₂ ) = (- 1, 4)
m = [tex]\frac{4-6}{-1-5}[/tex] = [tex]\frac{-2}{-6}[/tex] = [tex]\frac{1}{3}[/tex] , then
y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 4 ) , then
4 = - [tex]\frac{1}{3}[/tex] + c ⇒ c = [tex]\frac{12}{3}[/tex] + [tex]\frac{1}{3}[/tex] = [tex]\frac{13}{3}[/tex]
y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{13}{3}[/tex] ← equation of line
-----------------------------------------------------------------------
The equation of a line in point- slope form is
y - b = m(x - a)
m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (- 2, 0 ) , then
y - 0 = 3(x - (- 2) ) , that is
y = 3(x + 2)
y = 3x + 6 ← equation of line

Solve the equation 7(w + 13) = 35.
I know that it is:
7w + 20 = 35
- 20 - 20
7w/7 = 15/7
But I just don't know what 15 divided by 7 is as a fraction. Some one please help this is due in a week!
Answer:
w = -8
Step-by-step explanation:
7(w + 13) = 35
Divide each side by 7
7/7(w + 13) = 35/7
w+13 = 5
Subtract 13 from each side
w+13-13 =5-13
w = -8
Or you can distribute
7w +91 = 35
Subtract 91 from each side
7w+91-91 = 35-91
7w = -56
Divide each side by 7
7w/7 = -56/7
w = -8
Answer:
7(w+13)=35 {Here, 7 is wholly multiplied to w and 13}
7w+91=35
7w=35-91= -56
w= [tex]\frac{-56}{7}[/tex]
w= -8
Proof:
7(-8+13)= -56+91= 35
Therefore, w= -8

Solve the equation -8(n + 7) = -88. What are two ways to start solving this equation? Choose BOTH ways.
1) Subtract 7 from both sides.
2) Use the distributive property.
3) Add 8 to both sides.
4) Add 88 to both sides.
5) Divide both sides by -8.
Answer:
Divide each side by -8
Distribute
Step-by-step explanation:
-8(n + 7) = -88.
Method 1
Divide each side by -8
n+7 = 11
Subtract 7 from each side
n = 4
Method 2
Distribute
-8n-56= -88
Add 56 to each side
-8n = -32
Divide by -8
n=4
Answer:
Distributive property & dividing -8 on both sides.
Step-by-step explanation:
You can begin solving the equation by either using the distributive property or dividing -8 on both sides.
Distributive Property:
[tex]-8(n+7)=-88\\-8n-56=-88\\-8n=-32\\n=4[/tex]
Dividing:
[tex]-8(n+7)=-88\\n+7=11\\n=4[/tex]

Answer:
a) x = 11, b) x = 2/5, c) x = 1/2
Step-by-step explanation:
a)
11 x 11 x 11 = 1,331
Therefore, the answer is x = 11
b)
Reduce the fraction by the highest number 64 and 1000 go into. (which is 8)
So it'll turn into [tex]\sqrt[3]{\frac{8}{125} }[/tex]
Then reduce the fraction again, which will leave you with [tex]\frac{2}{5}[/tex]
Therefore, x= 2/5
c)
Reduce the fraction using 27.
That will give you [tex]x^{3} = \frac{1}{8}[/tex]
Then simplify the equation, which will give you [tex]x=\frac{1}{2}[/tex]
HELP PLEASE! Write an equation with variables on both sides that has a single solution "-1." Explain how to find that solution
ANSWER : HEY MATE
The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step
Let's create an equation with variables on both sides that has a single solution of "-1."
Let's call the variable "x."
An equation that meets these criteria is:
2x + 3 = x + 2.
We want to isolate the variable "x" on one side of the equation to find the solution.
Start by simplifying both sides of the equation.
On the left side, we have; 2x + 3;
And, on the right side, we have x + 2.
Now solve the equation as;
2x + 3 = x + 2
Subtract x on both sides;
2x - x + 3 = 2
x + 3 = 2
Subtract 3 on both sides;
x = 2 - 3
x = - 1
So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

height = 8,
so area = 8√2 × 8 (since the diagonal and the height makes the rectangle JFHL
so, 8√2 × 8
= 64√2

i have 30 coins. some of them are dimes, and some of them are quarters. in total, i have $4.05. how many of each coin do i have?
Answer: 23 dimes & 7 quarters
Step-by-step explanation:
Dimes = 10¢ = $0.10Quarters = 25¢ = $0.25Number of dimes = xNumber of quarters = yYou can create two equations:
[tex]\left \{ {{x + y = 30} \atop {0.10x + 0.25y =4.05}} \right.[/tex]
Rearrange x + y = 30:
[tex]y=30-x[/tex]
Substitute it into the x-value of the other equation & solve:
[tex]0.10x + 0.25y =0.10x + 0.25(30-x)=4.05\\0.10x+7.5-0.25x=4.05\\0.10x-0.25x=4.05-7.5\\-0.15x=-3.45\\x=\frac{-3.45}{-0.15} =23[/tex]
With the x-value, substitute it back to the original equation to find y-value:
[tex]y=30-x=30-23=7[/tex]
Therefore, there are 23 dimes & 7 quarters.
There are 23 dimes and 7 quarters.
Given that, the total number of coins=30.
How to convert dimes to dollars?To convert dimes to dollars we need to multiply the number of dimes by 0.1.
Let the number of dimes be x, and then the number of quarters will be 30-x.
Now, x×0.1+(30-x)×0.25=4.05
⇒-0.15x=-3.45
⇒x=23
30-x=7
Hence, there are 23 dimes and 7 quarters.
