We need to find f(1)
f(1) means x=1
Now we look at the three inequalities and choose the one where x=1 satisfies
x<=-1 , -1<x<1 and x>=1
x=1 satisfies the inequality x>=1
so we use the third function to find f(1)
We plug in 1 for x and find f(1)
= 2 + 3 = 5
f(1) = 5
I believe the answer is 6
Answer:
r = 3.7 cm
Step-by-step explanation:
19.02 = 1/2π(2radius) + diameter
expanding:
19.02 = 1/2(3.14)(2r) + 2r
19.02 = 3.14r + 2r = 5.14r
r = 19.02/5.14 = 3.7 cm
If you want an expression it would be 9-5x
Let's do this in steps, show your work! | <em>Make sure to ask questions!</em>
#1. Simplify 5x - 4 + 3 to 8x - 4.
<u>8x - 4 = 36.</u>
#2. Add 4 to both sides.
<u>8x = 36 + 4. </u>
#3. Simplify 36 + 4 to 40.
<u>8x = 40.</u>
#4. Divide both sides by 8.
<u>x = 40/8.</u> <------ <em>It turned into a fraction because it's easier to not divide a decimal. </em>
#5. Simplify 40/8 to 5.
<u>x = 5. </u>
<h3>Therefore, x = 5.</h3>
