Answer: 30%
Step-by-step explanation:
The first step is to find the increase in numbers
26-20= 6
Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number
6/20= 0.3
To convert that to percent, multiply it by 100
0.3 * 100= 30%
There was a 30% increase.
2)0
3)8
4)-6
Help me out guys.
Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8
Answer:
3) 8
Step-by-step explanation:
Real and unequal:
B² - 4AC > 0
Irrational: B²-4AC not a perfect square
The system has exactly one solution.
B.
The system has no solution.
C.
The system has infinitely many solutions.
Hi Brainiac
x+y=3
3x+3y=15
We need to solve for x+y=3 for x
So let's start by adding -y to both sides
x+y-y=3-y
x= -y+3
Now we need to substitute -y+3 for x in 3x+3y=15
3x+3y=15
3(-y+3)+3=15
9=15
Next, add -9
9-9 = 15-9
0=6
