Answer:
y=22.6x+52.332020
Step-by-step explanation:
Subtract 9 from both sides of the '=' sign
9 - 9 + b = -8 -9
b = -17 That's the answer.
Do 45/225 and simplify and that’s your answer
Answer:
1 solution
no solution
infinitely many
1 solution
Step-by-step explanation:
1. 2.3x-7=-7
2.3x=0
x=0
2. 3x=5+3x
0x=5
x=5/0
That’s undefined
3. 40-4x=4(10-x)
40-4x=40-4x
They both are equal no matter what. So, infinitrly many
4. -7+x=-(x+7)
-7+x=-x-7
2x=0
x=0
1 solution I.e 0
