Answer:
y = 3x - 6
Step-by-step explanation:
What you do is you plug both points in for the equation 2 times and solve as a system of equations.
Equation of a line: y = mx + b
(x,y) = (3,3)
(x,y) = (6,12)
3 = 3m + b
12 = 6m + b
Subtract equations to get rid of b to solve for m.
12 - 3 = 6m - 3m + b - b
9 = 3m
m = 3
Plug m back into both equations get b.
3 = 3(3) + b
b = -6
12 = 6(3) + b
b = -6
y = 3x - 6
Answer:
[tex]\displaystyle y = 3x - 6[/tex]
Step-by-step explanation:
First, find the rate of change of the line:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-3 + 12}{-3 + 6} = m \hookrightarrow \frac{9}{3} = m \\ \\ \boxed{3 = m}[/tex]
_______________________________________________
Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:
[tex]\displaystyle 12 = 3[6] + b \hookrightarrow 12 = 18 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}} \\ \\ OR \\ \\ 3 = 3[3] + b \hookrightarrow 3 = 9 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}}[/tex]

Sorry my writing is so messy, but basically I found all possible zeros by finding the factors of 24:
(Positive or negative) 1,2,3,4,6,8,12,24
Then, using remainder theorem (when you plug potential zeros into the x values to see if the equation will equal zero) I found out that 1 made the equation equal zero, and therefore was a zero.
Then I used synthetic division to make the equation smaller (I also used 2 because I found out that it was a zero using remainder theorem, same as how I found out 1)
Once I divided it small enough to factor, I simply factored it to find the last 2 zeros
(I didn’t explain everything 100% bc I don’t know how much of this you have learned so if you want clarification on something let me know)

Joe has $6.40 in nickels and quarters. He has two more nickels than quarters. How many quarters does Joe have?
Answers
Answer:
Quaters - Q=12
Dimes - D=10
Nickels - N= 48
Step-by-step explanation:
First, notice that $6.40 = 640 cents. The corresponding linear equation and a solution is shown below in several steps:
Original equation for amount of Dimes (D):
10*D + 25*(D+2) +5*4*(D+2) = 640
Simplified as following, resulting in the answer for D:
55*D=550
D=10
thus having the amount of Quarters:
Q=12
and correspondingly, amount of Nickels:
N= 48
Answer:
Quarters = 12
And correspondingly, amount of Nickels:
Nickels = 48

What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
To solve this problem, we first need to calculate the original surface area of the complex solid.
The complex solid is composed of two rectangular prisms, one with dimensions 9.8 ft × 6.5 ft × 8.1 ft and one with dimensions 10.6 ft × 4.3 ft × 6.5 ft.
The surface area of the first rectangular prism is:
2(9.8 × 6.5) + 2(9.8 × 8.1) + 2(6.5 × 8.1) = 464.82 ft²
The surface area of the second rectangular prism is:
2(10.6 × 4.3) + 2(10.6 × 6.5) + 2(4.3 × 6.5) = 411.22 ft²
So the total original surface area of the complex solid is:
464.82 + 411.22 = 876.04 ft²
Now we need to find the new surface area, which is exactly 14 times the original surface area.
Therefore, we can write:
New surface area = 14 × original surface area
New surface area = 14 × 876.04
New surface area ≈ 12264.56 ft²
Thus,
The new surface area is approximately 12264.56 ft².

A triangle has an angle that measures 10°. The other two angles are in a ratio of 3:14. What
are the measures of those two angles?
Answers
Step-by-step explanation:
Need to FinD :We have to find the measures of other two angles of triangle.[tex] \red{\frak{Given}} \begin{cases} & \sf{The\ measure\ of\ one\ angle\ of\ traingle\ is\ {\pmb{\sf{10^{\circ}}}}.} \\ & \sf{The\ other\ two\ angles\ are\ in\ the\ ratio\ of\ {\pmb{\sf{3\ :\ 14}}}.} \end{cases}[/tex]
We know that,
The other two angles of triangle are in the ratio of 3 : 14. So, let us consider the other two angles of the triangle be 3x and 14x.Angle sum property,
The angle sum property of triangle states that the sum of interior angles of triangle is 180°. By using this property, we'll find the other two angles of the triangle.[tex]\rule{200}{3}[/tex]
[tex] \sf \dashrightarrow {10^{\circ}\ +\ 3x\ +\ 14x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {10^{\circ}\ +\ 17x\ =\ 180^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 180^{\circ}\ -\ 10^{\circ}} \\ \\ \\ \sf \dashrightarrow {17x\ =\ 170^{\circ}} \\ \\ \\ \sf \dashrightarrow {x\ =\ \dfrac{\cancel{170^{\circ}}}{\cancel{17}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{x\ =\ 10^{\circ}.}}}}_{\sf \blue {\tiny{Value\ of\ x}}}} [/tex]

Let f(x) = 3 * sqrt(x) + 7. Define g$to be the inverse of f.
What is the value of g(g(f(f(f(36)))))?
Answers
By using the definition of inverse functions, we will see that:
g(g(f(f(f(36))))) = f(36) = 25.
What are inverse functions?Two functions f(x) and g(x) are inverses if:
f( g(x) ) = x
g( f(x) ) = x
Then we can rewrite:
g(g(f(f(f(36)))))
First, we can see that:
g(f(f(f(36)))) = f(f(36))
Replacing that in our expression, we get:
g(g(f(f(f36))))) = g(f(f(36)))
And the above expression is equal to f(36), to be sure of that, let's replace:
u = f(36)
Then we can rewrite:
g(f(f(36))) = g(f(u))
And by definition, the above thing is equal to u:
g(f(u)) = u = f(36).
Finally, we conclude that:
g(g(f(f(f(36))))) = f(36) = 3*√36 + 7 = 3*6 + 7 = 25
