Answer:
2x + 10 =20
x^2 - 3 = 22
5x + 5 = 30
Step-by-step explanation:
Keeping in mind that x is 5, I just performed the operations to know what should be on the right side of the equal sign.
for eg: 2(5) + 10 = 20
(5)^2 - 3 = 22
5(5) + 5 = 30

Step-by-step explanation:
Average systolic blood pressure = x = 130
Standard deviation = s = 6
We are to find interval that represents the systolic blood pressure of middle 99.7% of the males.
According to the empirical rule:
a) 68% values lie within 1 standard deviation of the mean
b) 95% values lie within 2 standard deviation of the mean
c) 99.7% values lie within 3 standard deviation of the mean
So, 99.7% value will lie within 3 standard deviations from the mean.
We can express this range as:
( x - 3s, x + 3s)
= (130 - 3(6), 130 +3(6))
= ( 130 - 18, 130 + 18)
= ( 112, 148 )
Thus the interval from 112 to 148 contains the systolic blood pressure of middle 99.7% of the males in the certain town

Answer:
No solution
Step-by-step explanation:
3x - 2= 3x + 5
3x is canceled out so
- 2 ≠ 5
No solution
This is what it should look like!
If you need a bigger picture, I uploaded it as well.
Whenever you need help visualising a graph, you should try to use Desmos. However, know how to do it manually. The 3 on y < -2x + 3 is where you start on the y-axis (vertical line), then you move down 2, to the right 1 to place the x-axis point (horizontal line). Hope that helped!
