The graph for the system of inequalities without the shading of its solution set is shown on the coordinate grid. Choose the area that would be shaded to show the solution of this system.
9514 1404 393
Answer:
(C) Area 3
Step-by-step explanation:
The first inequality has positive slope and a y-intercept of -5. The variable x has a positive coefficient so we can determine the shading from ...
x ... > 5
That is, larger values of x are in the solution set. Shading is to the right of the line with positive slope, in areas 3 and 4.
__
The second inequality has negative slope and a y-intercept of -3. Both x and y have positive coefficients, so the shading can be determined from either of ...
... 2y < -6 . . . . . . lower values of y are in the solution set
x ... < -6 . . . . . . . lower values of x are in the solution set
These indicate the shading is below and to the left of the line with negative slope, in areas 2 and 3.
__
The area that is in the solution set of both inequalities is Area 3.

The measurts of the angles of a triangle are shown in the figure below. Solve for x.
33°
A
Answer:
Step-by-step explanation:
Step-by-step explanation:
sum of all Δ angles = 180°
33° + 90° + x = 180°
123° + x = 180°
x = 180° - 123°
x = 57°

[tex]y-y_1=m(x-x_1)[/tex]
Given the x1 and y1 = given point.
Substitution x1 = 2 and y1 = -8 in the equation.
[tex] \begin{cases} x_1 = 2 \\ y_1 = - 8 \end{cases} \\ y - ( - 8) = - 4(x - 2) \\ y + 8 = - 4(x - 2)[/tex]
Hence, the solution is C choice.
Answer[tex]y + 8 = - 4(x - 2)[/tex]

two friends have a conversation mario tells roberto "the money i have is twice that you have" roberto answer "if you give me 6 dollars will we both have the same amount" how much money have each of them?
Answer:
Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.
Step-by-step explanation:
Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.
M = 2R
M - 6 = R + 6
To isolate M, you need to add 6 on both sides.
M - 6 + 6 = R + 6 + 6
M = R + 12
M = 2R
Substitute M for the value above that we found.
R + 12 = 2R
Now we subtract R on both sides, so that only one side has the variable R.
R - R + 12 = 2R - R
12 = R
M = 2R
Substitute for the value of R.
M = 2 x 12
M = 24

Christian is planning a vacation and finds an airplane ticket that cost 180$. He found a promo code offering 17% off. Write a single algebraic expression that can be used to find the cost of Christian’s ticket after the discount.
Answer:
83/100 x 180
Step-by-step explanation:
We have to find the cost of the ticket after the discount.
100% - 17%= 83%
83% of the total percentage of the original price that he needs to pay.
So we do:
83/100 x 180
So, this would be the expression.
Hope this helps!:)

I legit do not know which it is.
Given:
The inequality is
[tex]c\leq 7[/tex]
Where, c is the number of cars in the parking lot.
To find:
The graph for the given inequality.
Solution:
We have,
[tex]c\leq 7[/tex]
Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.
Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.
In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.
Therefore, the correct option is D.
y = x + 8
4x – 2y = -12
Answer:
x = 14
y = 22
Step-by-step explanation:
y = x + 8
4x - 2y = -12
Solve
_____________
Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.
4x - 2(x + 8) = -12
Distribute :
4x - (2(x) + 2(8)) = -12
4x - 2x +16 = -12
Combine like terms :
2x + 16 = -12
Subtract 16 from both sides :
2x = -28
Divide 2 from both sides to get x alone :
x = 14
Now that we know what x is, substitute it in the first equation to get y :
y = (14) + 8
y = 22
Answer:
(2 , 10) or x = 2 & y = 10
Step-by-step explanation:
y = x + 8
4x – 2y = -12
1. Substitute x + 8 in for the y in the other equation.
2. Solve for x
3. Take the solution for x and substitute the number in for the x in y = x + 8.
4. Solve for y.
5. Your answer is the result.
4x - 2(x + 8) = -12 Distributive Property
4x - 2x - 16 = -12 Combine like terms
2x - 16 = -12 Isolate the x, so start by moving -16
+ 16 +16
2x + 0 = 4 Delete the 0. It is a place holder you don't need
2x = 4 Isolate the x by dividing both terms by 2.
2 2
x = 2
y = x + 8 Substitute the 2 in for x and solve the one step equation.
y = 2 + 8
y = 10
