Answer:
0, 1, or 2 solutions
Step-by-step explanation:
The equation |ax + b| = c
The equation have absolute value symbol
Absolute value always gives us the positive number.
For absolute value function , we need to consider two cases
positive and negative.
|x|=x for positive , and |-x|=x for negative case
For negative case we include negative sign
So |ax + b| = c can be written as 2 equations
(ax+b)=c (ax+b)=-c
So we will get maximum of 2 solutions
The equation |ax + b| = c must have 0, 1, or 2 solutions
2(5)^2+10
2(25)+10
50+10
60
Yes
-2
the second equation is the result of subtracting 2
We can think of this as an equality
5 Lawns = 8 Hours
If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:
5 x (5) = 8 x (5)
Therefore she mows 25 Lawns in 40 Hours
Hello,
x²+2*7x+49+y²+2y+1+14-49-1=0
==>(x+7)²+(y+1)²=36
Center is (-7,-1) and radius 6.
