Answer:
See below
Step-by-step explanation:
Let me give you an example to help;
[tex]y = 2x + 3[/tex]
This equation is in slope - intercept form, which can be demonstrated through the following notation -
[tex]y = mx + b - Where, m = slope, and, b = y - intercept[/tex]
Now to solve for the x - intercept, we will have to propose y as 0;
[tex]0 = 2x + 3,\\2x = - 3,\\x = - 3 / 2 = - 1 and 1 / 2[/tex]
Thus the x - intercept = - 1 and 1 / 2;
* Note that you can't solve a slope intercept form equation, unless it is a system of equations, and if that is the case just let me know and I can help you out with that *

Answer:
[tex]g^{-1}[/tex](x) = [tex]\frac{x+10}{5}[/tex]
Step-by-step explanation:
Given
g(x) = 5(x - 2)
let y = g(x) and rearrange making x the subject, that is
y = 5(x - 2) ← distribute
y = 5x - 10 ( add 10 to both sides )
y + 10 = 5x ( divide both sides by 5 )
[tex]\frac{y+10}{5}[/tex] = x
Change y back into terms of x with x = [tex]g^{-1}[/tex] (x) , thus
[tex]g^{-1}[/tex](x) = [tex]\frac{x+10}{5}[/tex]

Given the equation below, if x = 12, what is the value of y?
y= x + 15.1
Answer:
y = 27.1
Step-by-step explanation:
We have the value of x:
x = 12
and we need to find the value of y in the expression:
y = x + 15.1
as we can see by the equation, the value of y depends on the value of x.
thus, we substitute x = 12 on the previous equation:
y = 12 + 15.1
y = 27.1
the value of y is 27.1
5 times the cube of x divided by 4 times x
Answer:
5x^2/4
Step-by-step explanation:
5 times the cube of x divided by 4 times x
(5x^3)/4x=5x^2/4
Answer:
I'm not sure what the question is... but I'm guessing you have to put this in number form? If so, the answer would be 5x^3/4x
Step-by-step explanation:
When having a number times x instead of writing the multiplication sign you just put them next to each other. (5x)
When something is cubed that means it is to the power of three (5x^3)
Divided by four times x would be 4x

The Crafty Clay Art Show has invited Aaliyah to make and sell her famous decorative plates. She molds the plates out of clay and then paints them. There is a proportional relationship between the number of plates Aaliyah makes, x, and the amount of clay she uses (in pounds), y. To make 2 plates, Aaliyah uses 6 pounds of clay. Write the equation for the relationship between x and y. (In the form of y= mx)
Answer:
y=3x
Step-by-step explanation:
Number of plates Aaliyah makes=x
Amount of clay she uses (in pounds)= y.
There is a proportional relationship between x and y: y=mx
To make 2 plates, Aaliyah uses 6 pounds of clay.
Therefore:
x=2y=6Substituting the given values into the proportional relationship y=mx, we obtain:
6=2m
Divide both sides by 2
m=3
Therefore, the equation for the relationship between x and y is:
y=3x, where 3 is our constant of proportionality.

y=-3x+6 y=9 What is the solutions to the system of equations?
Answer:
(- 1, 9 )
Step-by-step explanation:
One of the equations gives y = 9, the y- value
To find the value of x, substitute y = - 3x + 6 , that is
- 3x + 6 = 9 ( subtract 6 from both sides )
- 3x = 3 ( divide both sides by - 3 )
x = - 1
Solution is (- 1, 9 )
Write an equation for line M please and thank you!!!
Answer:
y = -2x + 4
Step-by-step explanation:
First, find the slope by doing rise over run. I did this between the points (0, 4) and (2,0) This gives you -4/2 = -2.
Then, find the y-intercept, which is where the line goes through the y axis. This is at y = 4.
So, the equation is y = -2x + 4.
Answer:
y = -2x + 4
Step-by-step explanation:
Lets write the equation of the line in slope-intercept form. We need to find two things:
1) the y-intercept. When can find this by simply finding what y is equal to when x is 0. Taking a quick look, we can find that it is 4
2) the slope. To find the slope, we simply take the rate of change, or rise over run. Taking the section where x is between 0 and 2, we have, 4/2 = 2.
However, the line is moving downwards, so its a negative slope. This means the actual slope is -2.
Finally, slope-intercept form tells us that the line is y = mx + b, where m is the slope, and b is the y-intercept.
Therefore, the answer is:
y = -2x + 4

Need help!!! Now!!!
Answer:
50
Step-by-step explanation:
c = cell phone cost
t = 5c
computer = 2.5 t = 2.5 ( 5c) =12.5 c
The total = 925
c+t+ computer = 925
c + 5c+ 12.5c = 925
Combine like terms
18.5 c = 925
Divide each side by 18.5
18.5c /18.5 = 925/18.5
c = 50
Answer:
Step-by-step explanation:
From the end of the problem to the beginning of the problem (this is often how you need to "decipher" story problems...go at it backwards!), we see that the cost of everything Tony bought is, in the end, based on the cost of the cell phone. The TV is 5 times as much as the cell phone, and the computer is 2.5 times as much as the TV...which is based on the cell phone. So the cell phone is our "main" unknown. We'll call that x.
If the TV is 5 times the cell phone, then the
TV = 5x
If the computer is 2.5 times the TV, then the
computer = 2.5(5x) = 12.5x
The cost of all these added together is 925. Therefore,
x + 5x + 12.5x = 925 and
18.5x = 925 so
x = 50
The cell phone cost $50. Choice G.

Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
7x−3(x−6)=2
Distribute
7x -3x + 18 = 2
4x +18 =2
Subtract 18 from each side
4x +18-18 = 2-18
4x = -16
Divide by 4
4x/4 = -16/4
x = -4

Answer:
y = [tex]\frac{3}{4}x+2[/tex]
Step-by-step explanation:
In the figure attached,
Graph of the line passes through the two points (0, 2) and (4, 5).
Let the equation of this line is y = mx + b
Here m = slope of the line
b = y-intercept
Since slope of the line passing through two points is represented by,
m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{(5-2)}{(4-0)}[/tex]
= [tex]\frac{3}{4}[/tex]
Y-intercept of the line 'b' = 2 units
Therefore, equation of the line will be,
y = [tex]\frac{3}{4}x+2[/tex]
Solving 2+2x=3+2x can provide justification that the equation does not have a solution. Investigate this equation using a graph and inverse operations.
Step-by-step explanation:
The main goal is to separate the values on opposite sides of the equal sign.
2 + 2x = 3 + 2x
-2 -2 ⬅Subtract 2 from both expressions
2x = 1 + 2x
-2x - 2x ⬅Subtract 2x from both sides.
0 = 1
Answer:
0 does not equal 1, which means that this equation is inconsistent. In other words, there is no solution. 0 does not equal 1, so 2 + 2x does not equal 3 + 2x.

Describe and correct the error in finding csc θ, given that θ is an acute angle of a right triangle and cos θ =7/11
Answer:
cosecθ = 1/sinθ = 11/6√2Step-by-step explanation:
Given that cos θ =7/11, cosec θ = 1/sinθ in trigonometry.
Based on SOH, CAH, TOA;
cosθ = adjacent/hypotenuse = 7/11
adjacent = 7 and hyp = 11
Since sinθ = opp/hyp, we need to get the opposite to be able to calculate sinθ.
Using pythagoras theorem to get the opposite;
[tex]hyp^{2} = adj^{2} + opp ^{2} \\opp = \sqrt{hyp^{2} - adj^{2} } \\opp = \sqrt{11^{2} - 7^{2}} \\opp = \sqrt{72} \\opp = 6\sqrt{2}[/tex]
sinθ = 6√2/11
cosecθ = 1/sinθ = 1/( 6√2/11)
cosecθ = 1/sinθ = 11/6√2
Note the error; cscθ[tex]\neq[/tex] 1/cosθ but cscθ = 1/sinθ

The complete factorization of -12x^3 + 14x^2 +6x is -2x(ax + 1)(2x-3). What is the value of a?
Answer:
a = 3
Step-by-step explanation:
-12x³+14x²+6x = -2x(ax+1)(2x-3)
Divide both sides by -2x(2x-3)
[tex]\frac{-2x(ax+1)(2x-3)}{-2x(2x-3)} = - \frac{12x^{3} }{-2x(2x-3)} + \frac{14x^{2} }{-2x(2x-3)} +\frac{6x}{-2x(2x-3)}[/tex]
ax+1=3x+1
Subtract 1 from both sides
ax=3x
Divide both sides by x
a=3

A movie theater sells popcorn in bags that open to form similar prisms, as shown. The large bag has a volume of 576 cubic inches. What is the volume of the small bag?
Answer:
Can't be determined
Explanation:It can't be determined since there are two sides that you need to find out.
Answer:
432 cubic inches
Step-by-step explanation:
the ratio of the small bag to large bags side lengths is 12/16
if you want to find the small bags volume, set the ratios equal
we know the large bag is 576 cubic inches so the small bag volume is x
12/16 = x/576
cross multiply
16x= 6912
divide by 16
x= 432
