solve each linear system by GRAPHING. CHECK YOUR ANSWER
2.) x - y = 6
2x = 12 + 2y
3.)1/2 x - y = 4
2y = x + 6
Answer:
2.) Infinitely many solutions
3.) No solutions
Step-by-step explanation:
To solve systems of equations graphically, you need to find where they intersect
2.) First put each equation in the form y=mx+b
x-y=6 -> y= x-6
2x=12+2y -> y= x-6
Then, graph each line
Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.
To check, plug a point in from the graph into both equations and you should get 0=0
3.) First put each equation in the form y=mx+b
1/2x-y=4 -> y=1/2x-4
2y=x+6 -> y=1/2x+3
Then, graph each line
Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.
To check your answer, you would one equation as the y in the other equation.
2(1/2x-4)=x+6, then solve for x
Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

40000 people visited the Emirates Park Zoo in Abu Dhabi last Year. Ratio of number of visitors of children to women to men is 4: 7: 9. Find the number of children, women and men who visited the zoo.
Answer:
40000 total visitors
Step-by-step explanation:
Let p represent a multiplier. Then the total number of visitors to the park is
4p + 7p + 9p = 40000.
This simplifies to 20p = 40000, so that p = 2000.
Then the number of children who visited is 4p = 8000; the number of women is 7p = 14000, and the number of men is 9p = 18000.
Summing up these results gives us the total number of chidren, women and men who visited the zoo last year: 8000 + 14000 + 18000, or 40000.

Which equation represents the solution of the equation 6x – 18 = 30?
Answer:
x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-18-(30)=0
STEP 1:
Pulling out like terms
Pull out like factors :
6x - 48 = 6 • (x - 8)
STEP 2:
Equations that are never true:
Solve: 6=0
This equation has no solution.
Solving a Single Variable Equation:
Solve : x-8 = 0
Add 8 to both sides of the equation :
x = 8

There is a bag filled with 4 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 red?
Answer:
im not sure but this is just a guess (please keep it in mind)
Step-by-step explanation:
4+5= 9 marbles all together
9-1= 8
1 in 8? or 1 in 9
this is becuase we dont know if the one that was taken out randomly first wasnt a red or not but then i could be wrong and the fact if it was red or blue in the first place might not even matter. it really depends.

Mike compared the y-intercept of the graph of the function
f(x) = 5x + 12 to the y-intercept of the graph of the ilnear function that
includes the points from the table below. What is the difference when the y-
intercept of f (x) is subtracted from the y-intercept of g (x)?
Х
1 3 5 6
g(x) 10 14 18 20
Answer:
-4Step-by-step explanation:
Given function
f(x) = 5x + 12From the table we get the function g(x), use pairs (1, 10) and (3, 14)
The slope:
m = (14 - 10)/(3 - 1) = 4/2 = 2The y-intercept:
10 = 2(1) + bb = 10 - 2b = 8The function g(x) is found as:
g(x) = 2x + 8The y- intercept of f (x) is subtracted from the y-intercept of g (x):
8 - 12 = -4Answer:

Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?
Answer:
14
Step-by-step explanation:
7.5x + 25 = 130
-25 -25
7.5x = 105
[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]
x = 14
Hence, she must make 14 visits in order to earn a free movie ticket.
Find the geometric mean between 4 and 20.
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Geometric mean is when you multiply the two numbers 4 and 20 and then take the square root of the product.
So 4 x 20 = 80, and the [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex]
However-- that's if you meant finding the geometric mean of 4 and 20 when you said "between"

Answer:
x = 119, y = 55
Answer:
x = 119°
y = 55°
Step-by-step explanation:
y + 125 = 180 {linear pair}
y = 180 - 125
y = 55°
Sum of all the angles of quadrilateral = 360
x + 55 + 72 +114 = 360
x + 241 = 360
x = 360 - 241
x = 119°
