Answer:
B
Step-by-step explanation:
r = 14/2 = 7units
Answer: x = 4 and y = -3
Step-by-step explanation:
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.
3(-2 -2y) + 5y = -3
-6 - 6y + 5y = -3
-y = 3
y = -3
Now that we know y, we plug it into the original equation and solve for x.
2x + 4(-3) = -4
2x + -12 = -4
2x = 8
x = 4
You can check the answer by plugging both x and y into either of the original equations.
Answer:
(-2x - 6)
Step-by-step explanation:
The given expression is ( 3x - 5 ) - ( 5x + 1 )
We have to simplify the given expression
First we will open the bracket having negative notation outside.
( 3x - 5 ) - 5x - 1
3x - 5 - 5x - 1
Now we will collect the similar terms together.
3x - 5x - 5 -1
-2x - 6
So the simplified form of the expression is (-2x - 6)
Answer: For y it's y=4x−12 and for x it's x=12+y/4
Step-by-step explanation:
SOLVING FOR X
8x-2y=24
2(4x−y)=24
4x−y=24/2
4x−y=12
4x=12+y
x=12+y/4
SOLVING FOR Y
8x-2y=24
2(4x−y)=24
4x−y=24/2
4x−y=12
−y=12−4x
y=−12+4x
y=4x−12
Hope this helps, have a BLESSED AND WONDERFUL DAY! As well as a great Black History Month and Valentine's day! :-)
