Answer:
The ordered pair solution is (-2,2)
Step-by-step explanation:
Here, we want to get the ordered pair solution to the system of linear equations
From the first equation, we can have it that;
-2x = 16-6y
Now, we can substitute this into the second equation as follows;
From; -4x -3y = 2
2(-2x) - 3y = 2
2(16-6y) - 3y = 2
32 - 12y - 3y = 2
32-15y = 2
-15y = 2-32
-15y = -30
y = -30/-15
y = 2
Recall;
-2x + 6y = 16
substitute for the value of y
-2x + 6(2) = 16
-2x + 12 = 16
-2x = 16-12
-2x = 4
x = 4/-2
x = -2
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8
Answer:
x =

Hello!
So, we know that the length of the rectangular basketball court is 84 ft, and the width is 50 ft.
The formula for perimeter of a rectangle is:
P = 2l + 2w
This means that we need to multiply the length by two and the width by two as well.
Substitute:
P = 2(84) + 2(50)
P = 168 + 100
P = 268 ft
ANSWER:
The perimeter of the basketball court is 268 feet long.
Answer:
8
Step-by-step explanation:
The x intercept is when y = 0
x + 3(0) = 6
x = 6
So (6,0) and m = 6
the y intercept is when x = 0
0 + 3y = 6 Divide by 3
y = 6/3
y = 2
the y intercept is (0,2) and n = 2
Answer
m + n = 6 + 2 = 8
