Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1
x=-5
those are ur answers
y= -2
x= -5
hope this helped:D
Answer:
2 step proof, Subtraction Property
Step-by-step explanation:
This one is pretty easy if you know a shortcut. Addition, Subtraction, Multiplication, and division properties.
Think about it this way. Subtract angle 1 from QUS. Then subtract angle 2 from RUT. Knowing RUT is equal to QUS means that the differences are the same.
Don't know if this is right or not but hope this helps.
Here's my work
Answer:
(4, 6 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 36 → (1)
y = -
x + 8 → (2)
Substitute y = -
x + 8 into (2)
3x + 4(-
x + 8) = 36 ← distribute and simplify left side
3x - 2x + 32 = 36
x + 32 = 36 ( subtract 32 from both sides )
x = 4
Substitute x = 4 into (2) for corresponding value of y
y = -
× 4 + 8 = - 2 + 8 = 6
solution is (4, 6 )
Answer:
114 3/4
Step-by-step explanation:
Convert decimal to fraction.
114.75 = 11475/100
Then simplify it. 459/4 = 114 3/4
Answer:
yes, $20.
Step-by-step explanation:
If you draw a line through the points it makes a straight line, so it is linear. And you get $20 by dividing $100 per the 5 people.
