Answer: (4, -9)
<u>Step-by-step explanation:</u>
Use elimination method. Manipulate one (or both) equations to eliminate one of the variables and solve for the remaining variable. <em>I will be eliminating y</em>
6x + y = 15 → 2(6x + y = 15) → 12x + 2y = 30
-7x - 2y = -10 → 1(-7x + 2y = -10) → <u> -7x - 2y = -10</u>
5x = 20
x = 4
Next, replace "x" with "4" into either equation and solve for y.
6(4) + y = 15
24 + y = 15
y = -9
<u>Check:</u>
Plug in x = 4 and y = -9 into the other equation to verify it makes a true statement.
-7x - 2y = -10
-7(4) - 2(-9) = -10
-28 - -18 = -10
-28 + 18 = -10
-10 = -10 
Answer:
The answer is 8 : 22, 12:33 as they are two equelivant ratios 11 and 4
Answer:
The answer is

Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To write an equation of a line given a point and slope we have
y - y1 = m( x - x1)
where (x1 , y1 ) is the point and m is the slope
Equation of the line using point P(3 , 5) and m = 2/3 is



We have the final answer as

Answer:
R is a function.
Step-by-step explanation:
Act like it's a whole circle and find the perimeter, then divide by 2.
P = 2 * pi * r
P = 2 * 3.14 * 9
P = 56.52
Now divide by 2:
P = 28.26
