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
1) y= 2/5x -3
2) y= 2/3x + 1
3) y= 2x -1
4) y= 5/4x + 3
I think
the probability is 5 out of 20
5x^2 -15x-140
5(x² -(3x) -28)
5(x² +(4x-7x)-28)
5(x(x+4) -7(x+4)
5(x-7)*(x-4)
Answer:
62 square cm
Step-by-step explanation:
The whole rectangle 12X10 = 120
Now subtract 2 restangles:
5x8 =40
6x3 =18
30+18= 58
120-58 =62
