Step by step explanation
area= 2πrh
-> 2 * 3.14 * 2 * 9
-> 6.28 *18
-> 113.04
The first one is the last answer because you subtract 18 and when you divide you change the inequality symbol
the second one is the last answer for the same reason
the 3rd one is x<-1.25
the 4th one is x<8/15

Step-by-step explanation:
<u>Step 1: Define</u>
0 = 4x + 4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4 on both sides: -4 = 4x
- Divide 4 on both sides: -1 = x
- Rewrite: x = -1
Answer:
Step-by-step explanation:
We can solve the first equation, f of -3. The value of the function f is , and plugging in -3 gets us , this results in 10 divided by negative 2, which is negative 5.
Now, we must solve g of negative one third. The function g is defined as . Plugging in negative one third into the question gets us
9 times negative one third is -3, and -3 minus 15 is -18. The absolute value of -18 is 18.
Now, we must solve h of negative 2, and h is defined as . Plugging in negative 2, we have . Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13
Answer:
x = 10
Step-by-step explanation:
For the lines to be parallel, the two angles must have the same measure:
80 - x = 90 - 2x
x = 10 . . . . . . . . . add 2x-80
The value of x must be 10 to make the lines parallel.
