A+b=32
4a+7b=200
a = 15
b = 20
There are 15 four pointers and 20 seven pointers. You can plug in the numbers to check.
I believe this is correct. If not i am extremely sorry.
Have a wonderful day :)
Answer:54
Step-by-step explanation:
72 classes in one year
75% spent outside
72x0.75=54
Thank you for asking this question. Here is your answer:
M = y2 - y1/x2 - X1 = M
= 290 - 210/120 - 80
M = 80/40
M = 2
Now we will consider y intercept
y = mx + b
210 = 2(80) + b
210 = 160 + b
b = 210 - 160
= 50
Now we will combine everything in order to get the answer.
y = 2x + 50
y = 2(60) + 50
y = 120 + 50
y = 170
So the final answer for this question is $170.

Answer:
(3x - y + 2)(3x + y - 2).
Step-by-step explanation:
9x^2 - y^2 + 4y - 4
= 9x^2 - (y^2 - 4y + 4)
= 9x^2 - (y - 2)^2
= (3x - (y - 2))(3x + (y - 2)
= (3x - y + 2)(3x + y - 2).
