What is the graph description for y=-10x
solve for x
z=5x-11y
x=?
Answer:
x= z+11y/5hope it helps
Answer:
[tex]x = \frac{z + 11y}{5}[/tex]
Step-by-step explanation:
To solve for x, given the equation: z = 5x - 11y
Add 11y to both sides:
z + 11y = 5x - 11y + 11y
z + 11y = 5x
Divide both sides by 5 to isolate x:
[tex]\frac{z + 11y}{5} = \frac{5x}{5}[/tex]
[tex]\frac{z + 11y}{5} = x[/tex]

Write an equation of the line containing the given point and parallel to the given line.
(6,-9); 5x - 9y = 8
.....
Answer:
y = 5/9x - 37/3
Step-by-step explanation:
5x - 9y = 8
-9y = -5x + 8
y = 5/9x - 8/9
When a line is parallel, the slope remains the same.y = 5/9x + b
-9 = 5/9(6) + b
-9 = 10/3 + b
-37/3 = b

Jonathan is signing a lease for an apartment that rents for $1240/month.
How much will he pay to move in if he must pay the first and last months’ rent and a security deposit equal to 80% of his monthly rent?
$2976
$3472
$3542
$3720
The required amount that Jonathan needs to pay to move in the apartment is $3472.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Jonathan is signing a lease for an apartment that rents for $1240/month.
According to the condition, he must pay the first and last months’ rent and a security deposit equal to 80% of his monthly rent.
So,
Total amount to pay = sum of the first and last month rent + 80% of a month rent
Total amount to pay = 1240 + 1240 + 80% of 1240
Total amount to pay = 2480 + 0.80[1240] = $3472
Thus, the required amount that Jonathan needs to pay to move in the apartment is $3472.

which of the following are the coordinatesof point f the image of point f after a rotation of 90 degrees about the origin
Answer:
It should be (3,0)
Step-by-step explanation:
a perpindicular line creates a 90º angle so following those lines makes the 0 on the x axis and since coordinates are x,y it should be (0,3)
Solve ax + b = cx + d for x.
(Hint: Use the distributive property, where ax + bx = x(a + b).)
Answer: X = (d-b) / (a-c)
This way this worded is weird but I think I got it
Step-by-step explanation:
Subtract B from both sides
ax = cx +d -b
Then subtract CX from both sides
ax -cx =d-b
Distributive Property
x(a-c) =d-b
Divide both sides by a-c
X = (d-b) / (a-c)

Hey! Please help! What is the slope of this line? I can't figure out how to read the graph correctly
Answer:
slope = -3
Step-by-step explanation:
The line is declining, which means that it will have a negative slope.
Using the slope formula:
m = (y2 - y1)/(x2 - x1)
Take two points from the graph:
Let (x1, y1) = (0, 2)
(x2, y2) = (2, -4)
m = (y2 - y1)/(x2 - x1)
m = (-4 - 2)/(2 - 0)
m = -6/2
m = -3
Therefore, the slope of the line is -3.
For your reference, attached is an edited screenshot of your given graph where it shows where I got the two points for solving the slope.

1. Which of these place values is found to the left of the 1 in 100?
O hundreds
tens
ones
thousands
Sorry I’m asking for help it’s just I don’t know my decimals
Answer:
Thousands
Step-by-step explanation:
If we place a number in left of the 1 in 100 then it's place value will be thousand.
e.g if we place 2 in left of the 1 in 100 then it's place value will be thousand (2,100).
The place value found to the left of the 1 in 100 is "tens." Option B
What are place values?The digit 1 in the hundreds place of the number 100 denotes the value of one hundred. In the tens spot, to the left of the 1, there is a 0, signifying that there are no tens in the given number. The final digit, 0, is in the ones position and stands for zero units. In our decimal system, place value knowledge is essential because it enables precise expression and comprehension of numerical values.
The place value system makes complicated numbers simpler and makes it possible for humans to carry out mathematical operations quickly. It lays the platform for more complex mathematical ideas and acts as the basis for computation.

r/3 - 6 = -3
Answer:
r = 9
Step-by-step explanation:
r/3 - 6 = -6
First, you need to add 6 on both sides to isolate r/3:
r/3 = 3
Then, you need to multiply both sides by 3 to get r alone:
r = 9
r is 9

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y<- 3/4X-1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
>= means greater than or equal to
<= means less than or equal to
---------------------------------------------
Part A
The graph of y >= -3x+3 will have a solid boundary line and the shading will be above the boundary line.
The boundary line y = -3x+3 has a negative slope so it moves down as you read it from left to right. It goes through the points (0,3) and (1,0)
--------------
The graph of y < (3/2)x - 6 will have a dashed or dotted boundary line. The shading is below the boundary.
The graph y = (3/2)x-6 goes through the two points (0,-6) and (2,-3)
--------------
If you graph both y >= -3x+3 and y < (3/2)x - 6 together, you get what you see in the attached image. This solution shaded region is the result of the overlapping prior shaded regions.
---------------------------------------------
Part B
Plug (x,y) = (-6,3) into each inequality to see if we get a true inequality or not
For the first inequality we have
y >= -3x+3
3 >= -3*(-6)+3
3 >= 18+3
3 >= 21
which is false. The value 3 is not larger or equal to 21. So right off the bat we know that (-6,3) is NOT a solution. It is NOT in the solution region.
Let's check the other inequality just for the sake of completeness
y < (3/2)x - 6
3 < (3/2)*(-6) - 6
3 < -9 - 6
3 < -15
this is also false. The value -15 is smaller than 3, since it is to the left of 3
We're given more evidence that (-6,3) is NOT in the solution area. It is outside of both shaded areas.
The Super Bowl half time show lasts 30 minutes. If the half time show is 1/7 of the total game time, how many hours is the Super Bowl from start to finish? Write your answer as a mixed number.
Answer:
3 1/2 hours.
Step-by-step explanation:
If the Half Time show is one-seventh of the show and lasts for 30 minutes, we can multiply that by 7 to get the total amount of minutes.
30 x 7 = 210
To convert the number of minutes to hours, 210 can be divided by 60 to result in a total of 3.5, therefore, the Super Bowl lasts for 3 1/2 hours.
factorize 18x-2x^3+9-x^2
Answer:
(3 - x)(3 + x)(2x + 1)
Step-by-step explanation:
18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )
= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term
= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )
= (3² - x²)(2x + 1)
= (3 - x)(3 + x)(2x + 1)
