PLEASE HELP! DUE TOMORROW 1-8-21 !! Look at these equations. Write each equation in slope-intercept form. Are these equations th
e same or different? Explain. I don’t know how to do the middle equation so please show work for that.
1 answer:
Answer:
y = 2x-4
all the equations are the same as the slope-intercept form is the same for all the equations
Step-by-step explanation:
slope-intercept form:
2x-3 = y+1
<h3>i) move y to the left-hand side and change its sign</h3>-y+2x-3 = 1
<h3>ii) move 2x-3 to the right-hand side and change its sign</h3>-y = 1-2x+3
<h3>iii) add the numbers</h3>-y = (1+3)-2x
-y = 4-2x
<h3>iv) change the signs on both sides of the equation </h3>y = -4+2x
<h3>v) use the commutative property to reorder the terms</h3>( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )
y = 2x-4

Given
first, convert
to base 25 to match the other term.
Substitute above identity into original equation:
Use substiution
above equation becomes
2/u-3u=1
multiply by u and solve for u:
=> u=2/3 or u=-1
case A:. u=2/3 =>
=>
case B: u=-1 =>
which does not give a real solution, so reject.
See graph below for confirmation of solution.
