<h3>
Answer: x = 4</h3>
==================================================
Explanation:
Replace f(x) with 0 and solve for x.
f(x) = 3x-12
0 = 3x-12
3x-12 = 0
3x = 12
x = 12/3
x = 4 is a zero, aka root, of the function
---------------
Check:
f(x) = 3x-12
f(4) = 3(4)-12
f(4) = 12-12
f(4) = 0
The answer is confirmed.
Answer:
Either A or D
A if I'm correct shows up as 64 x 0, which is zero
Then D may be right if A is wrong.
Given:
Area of a triangle = (h*b) / 2
Area of smaller triangle = (4cm * 4cm) / 2 = 16cm² / 2 = 8 cm²
Area of larger triangle = (6cm * 10cm) / 2 = 60cm² / 2 = 30 cm²
30cm² - 8cm² = 22cm²
Probability that the point is inside the large triangle but outside the small triangle:
22cm² / 30cm² → 11/15 → 0.73 or 73%
The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.
Tacking on "-8" to |x+5| leads to |x+5|-8
The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
Final Answer: choice C)
Hello!
The mean is the average of the data
To find the average you add all the numbers and divide the sum by the amount of numbers you added
14 + 19 + 13 + 22 + 7 = 75
You add 5 numbers so
75/5 = 15
The answer is 15
Hope this helps!
