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)
6^9 x 6^-7 = 6^2
x= -7
Hope this helps :)
Answer:
-a^2 -a -35
Step-by-step explanation:
a(4-a) -5(a+7)
Distribute
4a -a^2 -5a-35
Combine like terms
-a^2+4a -5a-35
-a^2 -a -35
