find the slope
(11, 7) and crosses the
y-axis of 17
Answer:
Slope of the line (m): -0.909090909091
Y-intercept of the line (b): 17.0
Slope Intercept Form (y = mx + b): y = -0.909090909091x + 17
Step-by-step explanation:
We have that the the slope (11, 7) and crosses the y-axis of 17 is
m=−0.909
From the question we are told
The the slope (11, 7) and crosses the y-axis of 17
Generally the equation for the Slope is mathematically given as
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\ Where\\\\\ Therefore\\\\m=\frac{17-7}{0-11}\\\\ m=-0.909[/tex]
Therefore
The the slope (11, 7) and crosses the y-axis of 17 is
m=−0.909

If the radius of a sphere is reduced to one-third, by how many times does its
volume decrease?
Answer:
It can be concluded that reducing the radius to one-third will reduce the volume of sphere 1/27 times
Step-by-step explanation:
The volume of a sphere is given by the following formula:
[tex]V = \frac{4}{3}\pi r^3[/tex]
Here r is the radius of the sphere
Reducing the radius of sphere to one-third means dividing the radius by three. So the new radius will be: [tex]\frac{1}{3}r[/tex]
The new volume with the new radius will be:
[tex]V_1 = \frac{4}{3}\pi * (\frac{1}{3}r)^3\\V_1 = \frac{4}{3}\pi * \frac{1}{27}r^3\\V_1 = \frac{1}{27}(\frac{4}{3}\pi r^3)\\V_1 = \frac{1}{27}V[/tex]
The new volume is 1/27 times of the original volume.
Hence,
It can be concluded that reducing the radius to one-third will reduce the volume of sphere 1/27 times

NEED HELP ASAP!! Is there enough information to prove that the triangles are congruent?
If yes, provide the correct Triangle Congruence Postulate or Theorem and a congruence statement.
If no, justify your answer.
Answer:
No.
There's no congruence theorem or statement that proves that 2 triangles with 2 sides and a non-included angle are congruent to each other.
Step-by-step explanation:
The triangles given, ∆ABC and ∆CYZ both have a non-included angle and two sides given that are congruent to each other.
However, this alone is not enough to prove that both ∆s are congruent to each other because there is also possiblity of another ∆ that will have the same two equal sides and a non-included angle as any of the 2, and can thereby have different shape and size.
There's also no congruency statement that proves that two triangles with congruent two sides and a non-included angle are congruent to each other.
Therefore, the information to us is not enough.

Q.Find the selling price if the cost price is $1200 and loss percent is 25?
Write in step by step
Step-by-step explanation:
C.p=1200
loss percent=25
s.p=?
s.p=100- loss×C.p/100
s.p=100- 25×1200/100
S.p=75×1200/100
s.p=90000/100
s.p=900

Answer:
B. 34º
Step-by-step explanation:
So we know that a straight line is equal to 180º and we already have to measure of angle 2. So to find the angle of measure 1, we just subtract 146 from 180.
180 - 146 = 34
So the measure of angle 1 is 34º.
Now, because of alternate exterior angles, we know that they would be the same. SO m∠7 = 34º

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Explain how to creatExplain how to create an equation with infinitely many solutions.
e an equation with infinitely many solutions.
Answer:
In this case, the idea is that you have to create something that makes both the right side of the equation and the left side to be equal to each other which gives you an infinite number of solutions. so if you have 5x-8 on the left, you need 5x-8 on the right for everything to cancel and end up with 0=0.
Step-by-step explanation:
Answer: You can start with any statement in the form a = a. Then add the same variable term to both sides, and add the same constant term to both sides. Combine like terms on each side.
