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

Find the value of each variable in the parallelogram.
Answer:
n = 12 , m = 5
Step-by-step explanation:
since it is said it is a parallelogram so opposite sides are equal
n = 12 (being opposite sides of parallelogram)
m + 1 = 6 (being opposite sides of parallelogram)
m = 6 - 1
m = 5

Plot the vertex and the axis of symmetry of this function on the provided graph.
f(x) = (x + 2)^2 − 6
Answer:
(-2,-6)
-2
Step-by-step explanation:
To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have
-2
this is the x coordinate of the vertex.
Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)
This is the y coordinate
which means we have (-2,-6)
the axis of symmetry is just the x coordinate of the graph
which is -2
Find the third side in simplest radical form
Answer:
√53
Step-by-step explanation:
hypotenuse (h) = √89
base (b) = 6
perpendicular (p) = ?
we know by using Pythagoras theorem
p = √(h² - b²)
= √(√89)² - 6²
= √ 89 - 36
= √ 53
To rent a bounce house: At Mike's Bounce Shop costs $30 plus $2 per hour. At Jose's Bounce Rentals, it costs $12 plus $8 per hour. After how many hours will the rental cost at both shops be equal? What do your variables represent?Solve the problem using the Equal Values Method. Show your work for finding x AND y.
Answer: After 3 hours both will have the same cost.
Step-by-step explanation:
Let x = Number of hours and y be the total cost.
Total cost = Initial cost + (cost per hour)(Number of hours)
At Mike's Bounce Shop,
Total cost (y)= 30+2x
At Jose's Bounce Rentals,
Total cost(y) = 12+8x
When both shops have the same cost, then
[tex]12+8x=30+2x\\\\\Rightarrow\ 8x-2x=30-12\\\\\Rightarrow\ 6x=18\\\\\Rightarrow\ x=3[/tex]
Total cost = 12+8(3)=12+24=$36
Hence, After 3 hours both will have the same cost.
solve it. also show you got the the answer. thank you.
Answer:
a) [tex]42\leq 5t[/tex]
b) 8
Step-by-step explanation:
a) The MAX is 42 basketballs, so it has to be either less than or equal to 42. each team wants 5 so you would multiply 5 basketballs per team (which is variable t)
b) Once you plug in 10 in replacement of 5 you get the inequality: [tex]42\leq 5 * 10[/tex]
once you figure it out you get [tex]42 \leq 50[/tex]. 50-42 = 8. Gopal should purchase at least 8 basketballs.

Given f(x)=8x−9
a. Find f(3y−1)=8(3y−1)−9=
b. If f(x)=−23, find the value of x.
Step-by-step explanation:
Given
f(x) = 8x - 9
Then
For a.
f(3y - 1 ) = 8(3y - 1 ) - 9
= 24y - 8 - 9
= 24y - 17
Now for b.
f(x) = - 23
or, 8x - 9 = - 23
8x = - 23 + 9
8x = - 14
x = - 14 / 8
x = - 7 / 4

Consider this system of equations, which equation represents the first equation written in slope-intercept form? 5x - 2y = 10 O y=x-5 oy-x+10 o y--x+10 O y=-5x -5 ..... brainlyist for who is right
Answer:
The answer is A
Step-by-step explanation:
this isnt my answer it is someone named baylee in the comments, i tried it and it was right .
As per the given data, the slope-intercept form of the first equation is y = x - 5, which is represented by option A.
What is slope-intercept?The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept.
The equation that represents the first equation written in slope-intercept form is:
y = x - 5
To convert the equation 5x - 2y = 10 into slope-intercept form, we need to isolate y on one side of the equation.
Starting with 5x - 2y = 10:
Subtract 5x from both sides: -2y = -5x + 10
Divide both sides by -2: y = (5/2)x - 5
Now, we can simplify the expression (5/2)x - 5 to the form y = mx + b, where m is the slope and b is the y-intercept.
Therefore, the correct option is A.

- x + 2y = 0
x + 2y = 1
Answer:
-no answer-
Step-by-step explanation:
Use elimination (subtract one equation from the other to get rid of one of the variables)
x+2y=1
- -x+2y=0
