Answer:
(-9, 5)
Step-by-step explanation:
there are 2 variable: x and y
eliminate one of the variables for example y
-x - y = 4
-2x - y = 13 multiply this equation by (-1)
-x - y = 4
2x + y = -13
add both equations
2x-x-y+y = 4-13
x = -9
substitute x = -9 in the first equation
-(-9)-y = 4
9 - y = 4 subtract 9 from both sides
-y = 4 - 9
-y = -5 multiply by (-1)
y = 5

Coach Wu has a total of 30 soccer balls. 9 soccer balls are white the remaining soccer balls are one of three different colors (blue, pink, or green) there is an equal number of blue, pink, and green balls. How many green soccer balls does Coach Wu have?
Answers
Answer:
Number of green soccer balls = 7
Step-by-step explanation:
Total number of soccer balls = 30
Number of white balls = 9
Number of soccer balls excluding number of white balls = 30 - 9 = 21
Also, the remaining soccer balls are one of three different colors (blue, pink, or green) such that there is an equal number of blue, pink, and green balls.
Number of blue balls = Number of pink balls = Number of green balls = [tex]\frac{21}{3}=7[/tex]
Therefore,
Number of green soccer balls = 7

Jasmine will buy the same number of stamps every month to add to a stamp collection her grandfather gave her. The table shows the number of stamps Jasmine will have at the end of x months. How many stamps was Jasmine given, and how many stamps will she buy every month?
Jasmine was given 65 stamps, and she will buy 5 stamps every month.
Jasmine was given 60 stamps, and she will buy 65 stamps every month.
Jasmine was given 5 stamps, and she will buy 60 stamps every month.
Jasmine was given 60 stamps, and she will buy 5 stamps every month
Answers
Answer:
Option (4)
Step-by-step explanation:
If we draw a graph against x(Number of months) and y(Number of stamps),
We will get a straight line.
Let the equation of straight line be,
y = mx + b
Here, m = Stamps purchased per month
b = Jasmine was given stamps initially
From the table attached,
m = [tex]\frac{70-65}{2-1}[/tex] = 5 stamps per month
Therefore, equation of the line will be,
y = 5x + b
Since, a point (1, 65) lies on this line,
65 = 5(1) + b
b = 60
That means she was given 60 stamps initially.
Option (4) will be the answer.

Answer: Yes these triangles are similar
Step-by-step explanation:
First lets write down what we know just to make life easier
x=9
TL should be similar to CH
LY should be similar to KH
The angles should be equal due to SAS
So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25 and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14
So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar. 35/2.5=14
Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5
Hope this helps.
