Answer:
(-3,2)
Step-by-step explanation:
From the number line graph we can see that there is a open circle at -3
and an open circle at 2.
The shaded part lies between -3 and 2
So we can write inequality form as -3<x<2.
Interval form
If we have open circle then we use parenthesis when we write it in interval notation. we have open circle at -3 and 2
So interval notation is (-3,2)
1298 - 4x =171 + 3x
Add 4x to both sides
1298 = 171 + 7x
Subtract 171 from both sides
1127 = 7x
Divide by 7 on both sides
x = 161
They will both say the number 161 at the same time.
4.)6 2(6) + 4
9 2(9)+ 4
15 2(15) + 4
Given: w²+9=6w [0, 3, 6, 9]
We need to substitute each number for w and find which works
Sub Zero: 0²+9=6×0
Simplify: 9=0. 9 does not equal 0, so it is not 0
Sub Three: 3²+9=6×3
Simplify: 9+9=18
Addition: 18=18
The statement 18=18 is true, therefore we have our answer.
Answer: The second option is correct. 3 would be the correct number to substitute to make the equation correct.
