Answer:
x = -1 and y = 4
Step-by-step explanation:
Step 1: Solve 3y = -x + 11 for x
3y + x= -x + 11 + x
x + 3y = 11
x + 3y - 3y = 11 - 3y
x = −3y + 11
Step 2: Substitute -3y + 11 for x in 2x + 4y = 14
2(-3y + 11) + 4y = 14
Simplify both sides of the equation, and you get −2y + 22 = 14
−2y + 22 − 22 = 14 − 22
-2y = -8
-2y/-2 = -8/-2
y = 4
Step 3: Substitute 4 for y in x = −3y + 11
x = -3(4) + 11
Simplify both sides of the equation, and you get x = -1
Answer:
Option B.
The first step is find the slope using the formula
The rate of change is m=3
Step-by-step explanation:
we know that
The equation of a line in slope intercept form is equal to
where
m is the slope
is the y-intercept
so
The firs step is determine the slope of the linear equation
The formula to calculate the slope between two points is equal to
we have
(-3,1) and (-4,-2)
substitute the given values in the formula
Remember that
In a linear equation the rate of change is a constant and is equal to the slope of the line
so
The rate of change is 3
OK so first I like to find what 10% is which in this case would be 1.8 and to find the other 5% you divide 1.8 by 2 which gets you .9 if you and 1.8 and .9 you get 2.7 and if you add 2.7 to 18 you get 20.7 which is your retail price
121 is the area of the square
