Answer:
<u>Option 3</u> satisfies the equation y = -2x + 1.
Step-by-step explanation:
7 = -2*-3 + 1 makes sense
-5 = -2*3 + 1 also makes sense
-9 = -2*-9 + 1 is correct
Have a nice day!
Answer:
a.) 2(2x)+2(4x-3)
b.)2(2x)+2(4x-3)=42
Step-by-step explanation:
b.)2(2x)+2(4x-3)=42
distribute
4x+8x-3=42
add the like terms
12x-3=42
move the -3 by adding to both sides
12x=45
divide both sides by 12
12x/12=45/12
x=3.75
and to make sure it's right, plug x into the equation.
2(2(3.75))+2(4(3.75)-3)=42
now multiply/add/subtract everything.
2x2x3.75=15 (This was the 1st set of parenthesis)
2x4x3.75-3=27 (This was the 2nd set of parenthesis)
15+27=42
42=42
Well 106 divided by 7 is 15 so 15 times 7 is 106
