Pavel [41]

5x² + |x+1| > 0
5x² + x + 1 > 0
x+1 > 0 because it came from absolute
5x² > 0 because it’s squared

When you try a number you should put it in the original equality
5x² + |x+1|

Allison measured a line to be 5.4 inches long. If the actual length of the line is 5.5 inches, then what was the percent error o

valentina_108 [34]

Answer:

1.85%

Step-by-step explanation:

→ Find the difference between the actual and predicted

5.5 - 5.4 = 0.1

→ Divide answer by 5.4

0.1 ÷ 5.4 = 0.01851851851

→ Multiply answer by 100

0.01851851851 × 100 = 1.85%

Which equation is the inverse of y=100-x2

Harman [31]

Answer:

Inverse of y = $f^{-1}(x)$ = $\sqrt{100 -x}$ .

Step-by-step explanation:

Given : f(x) = y = 100 - x²

To find : Find inverse.

Solution : We have given that :

f(x) = y = 100 - x²

Step1) : Replace every x with a y and replace every y with an x .

x = 100 - y².

Step 2): Solve for y

On subtracting 100 from both sides

x - 100 = -y²

On multiplying both side by -1

100 -x = y²

Taking square root both sides and switching sides

y = ± $\sqrt{100-x}$ .

Step3 ) : Replace y with $f^{-1}(x)$ .

$f^{-1}(x)$ = ± $\sqrt{100-x}$ .

Therefore, inverse of y = $f^{-1}(x)$ = ± $\sqrt{100-x}$ .

The temperature at sunrise was -3*F. By noon, the temperature climbed 18 degrees. By sundown the temperature was -14*F. How much

Natalija [7]

Answer:

32*F

Step-by-step explanation:

* = degrees

Started at -3*F

By noon, the temperature climbed 18* = +18*

By sundown the temperature was -14*F

What we want to know: How much did the temperature drop between noon and sundown?

This is actually really easy!

What was the temperature at noon? --> 18*F

What was the temperature at sundown? --> -14*F

So what is the difference between 18* and -14*? We can't use an equation, so we will solve manually.

The distance from -14 to 0 is 14 degrees. Keep that in mind.

The distance from 18 to 0 is 18 degrees. Keep that in mind.

So what is 14 + 18? 14 + 18 = 32*.

So, the temperature dropped 32*F between noon and sundown.

I hope this helps! I know this was a little messy, but that is because we couldn't use an equation/expression to solve this.
