Answer:
2x + y = -4
Step-by-step explanation:
standard form of equation of straight line is
ax+by = c
that is terms containing x and y should be on LHS and constant term should be on RHS
______________________________________________
Given equation
y + 1 = - 2x - 3
lets bring -2x on LHS ,
add 2x on lHS and RHS
y + 1 + 2x = - 2x - 3 + 2x
=> y + 1 + 2x = -3
on lHS, 1 is there which constant term lets bring it on RHS
subtract 1 from both sides
y + 1 + 2x - 1= -3 -1
y + 2x = -4
rearranging it
2x + y = -4 (Answer)
The equation you had:
6x + 5y = 45
Solve for Y:
5y = (-6x) + 45 divide by 5
y = (-6/5)x + 9
y = -1 1/5x +9
Answer:
(-4,4)
Step-by-step explanation:
So since the rule is (4x, 4y) all you have to do is multiply. -1 x 4 = -4 and 1 x 4 = 4.
Answer:
Step-by-step explanation:
1 21v - 21
2 3n - 12
3 48x + 18
4 -3b + 9
3,500 is the best estimate if you multiply 7 by round 456 to 500 so 7x500=3,500
