Answer:
x = 12
Step-by-step explanation:
9(x-11) = 9
divide by 9 by 9 x-11 = 1
add 11 to 1 x= 12
Pretty much you take a value on the left and do the opposite of what its doing and then do it to the number on the right. since 9 was going to multiply on the left, then you would divide it on the right
if you have any questions about how to solve it then let me know!

what is the answer to 3?
Answers
Answer:
Step-by-step explanation:
First, you have to find the perimeter of the base. You do that by adding all the sides,
There are two sides that are 13 mm and two sides that are 6 mm
13 + 13 is 26
6 + 6 is 12
26 + 12 is 38
Now you have the perimeter. Now you have to multiply is by the highest
So 38*14 (532)

The opposite angles are supplementary (meaning they sum up to 180 °)

20 + 4x = 180

Divide through by 4
x = 40 °
Angle at point A
(2x + 38) = (2(40) + 38) = 118 °

A store manager was trying to figure out how many people did their shopping online compared to doing it in stores. To do this she polled several houses in the nearby neighborhoods. The results are shown below:
Based on the information presented can you infer anything about the number of people who did their shopping online vs. in-store?
Answers
Based off of this information, it looks like there are more online shoppers than in-store shoppers, more simply because there are 4 arrays that have more online shoppers than in-store shoppers, and 3 arrays that have more in-store shoppers than online shoppers, and 1 array that has an even amount of shoppers. But if you add up the numbers for a total of 160/161, you see there are more in-store shoppers than online shoppers.
So there are more in-store shoppers total.

Solve the system of equations:
x+3y-z=9
2x+9y+4z=12
x+4y+z=7
Answers
[i] … … … x + 3y - z = 9
[ii] … … … 2x + 9y + 4z = 12
[iii] … … … x + 4y + z = 7
Eliminate z by combining …
• … 4 times equation [i] and equation [ii] :
4 (x + 3y - z) + (2x + 9y + 4z) = 4•9 + 12
(4x + 12y - 4z) + (2x + 9y + 4z) = 36 + 12
6x + 21y = 48
2x + 7y = 16
• … equation [i] and equation [iii] :
(x + 3y - z) + (x + 4y + z) = 9 + 7
2x + 7y = 16
Since we ended up with 2 copies of the same equation, we have infinitely many solutions for x, y, and z. That is, we have infinitely many choices for x and y that satisfy 2x + 7y = 16, and consequently infinitely many choices for z to satisfy any of the 3 original equations.
We can parameterize the solution by letting, for instance, x = t; then the solution set is
x = t
2x + 7y = 16 ⇒ y = (16 - 2t)/7
x + 3y - z = 9 ⇒ z = t + 3 (16 - 2t)/7 - 9 ⇒ z = (t - 15)/7
where t is any real number.

What is the y-intercept ??? Please show step by step!!
Answers
Answer:
(0, 1)
Step-by-step explanation:
The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.
Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.
Answer:
y-intercept is (0,1)
Step-by-step explanation:
When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis
We can see this in the chart but if that point is not on there, we have another way to find it.
This is the formula, point-slope form.
(Math people are not that creative, you use it when you have the slop and a point)
First, we need to find the slope
We do this by taking two points and using the formula y2-y1 over (/) x2-x1
So our formula is y2-y1/x2-x1.
If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope
3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point
So our equation now is 3-1/x2-x1
Now we have to sub in for the x’s
Do the same thing and our equation now is…
3-1/1-0
This gets us to 2/1 which is obviously 2.
Now we have our slope so we just have to fill in for the point.
Point slope form uses the model y-y1=m(x-x1)
So we use our same two points and get
Y-1=2(x-0)
Solve this out to Slope intercept form which will give us our y-intercept.
This gets us to y=2x+1 so our y-intercept is clearly still 1!
