Answer:
Step-by-step explanation:
f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12
Answer:
f(2) = 20
Step-by-step explanation:
f(x) = -x^2 + x + 14
f(2) = (2)^2 + (2) + 14
f(2) = 4 + 2 + 14
f(2) = 20
what is the solution set of this inequality x < -10 i need help
Answer:
x= 1 (any number greater than -10)
Step-by-step explanation:
">" this sign shows that any number greater than -10 can be x. There is no specific answer.
Answer:
The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.
Step-by-step explanation:
When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.

Find the value of x : x/15 = 8/20
Answer:
x=6
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
x/15=8/20
Multiply both sides by 10:
x/15*10=8/20*10
Simplify:8/20*10
2x/3=4
Multiply both sides by 3:
3*2x/3=4*3
simplify:
2x=12
Divide both sides by 2:
2x/2=12/2
Simplify:
x=6

Answer:
I attached the graph below
Step-by-step explanation:
I started at the y-intercept, because it is where the line crosses the y-axis. Then, I used rise/run for the slope (-5/3) and went down 5 units and right 3 units. I connected the points to make the graph.
At a dance, 25% dresses up in a superhero costume, 32% as a scary character, 10% as an entertainer, 15% as a children's movie character, and 16% did not dress up at all. If a total of 250 students attended the dance and 15% of the scary character students were girls, how many boys dressed up as a scary character?
Answer:
68 boys
Step-by-step explanation:
32% of 250 = 80
of 80 scary characters, 15% were girls
80 x .15 = 12 (girls)
80 - 12 = 68 (boys)
Given the functions f(x) = x ^ 3, g(x) = 9 and h(x) = 2x , what is an expression equivalant to f(2x) + 3g(x)/h(x) + 3?
Answer:
an expression equivalent to f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3
Step-by-step explanation:
As given ,
f(x) = x³ , g(x) = 9 , h(x) = 2x
Now,
f(2x) = (2x)³ = 2³.x³ = 8x³
⇒f(2x) = 8x³
Now,
[tex]\frac{g(x)}{h(x)} = \frac{9}{2x} = \frac{9}{2}x[/tex]
⇒[tex]3\frac{g(x)}{h(x)} = 3.\frac{9}{2}x = \frac{27}{2}x[/tex]
∴ we get
f(2x) + [tex]3\frac{g(x)}{h(x)}[/tex] + 3 = 8x³ + [tex]\frac{27}{2}x[/tex] + 3

s=2πcx+3πc^2 solve for x
Answer:
x = (s - 3πc^2) / 2πc.
Step-by-step explanation:
s = 2πcx + 3πc^2
2πcx = s - 3πc^2
x = (s - 3πc^2) / 2πc.

Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?
A 2
B 6
C 8
D 10
Answer:
6 miles.
Step-by-step explanation:
To solve this problem, lets make an equation in slope-intercept form (y = mx + b)
The initial fee is $6. This is our y-intercept (b) as it is unchanging.
Our slope (m) would be $3, as it changes value per mile, which will be represented by x.
$24 was the total fare, so this is our y.
We have:
24 = 3x + 6
Subtract 6 from both sides.
24 - 6 = 3x + 6 - 6
We get:
18 = 3x
Divide by 3 on both sides.
18/3 = 3x/3
We get:
6 = x
So, Mike traveled 6 miles.

Find the common difference of the arithmetic sequence. −16,−12,−8,−4,..
The sum of two numbers is 46 and their
difference is 20. What is the smaller
number?
1
A) 40
B) 13
C) 26
D) 12
Answer:
B. 13
Step-by-step explanation:
We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.
"The sum of two numbers is 46 and their difference is 20."
Meaning we have two equations :
X + Y = 46
X - Y = 20
Looking at the last part of "their difference is 20." We can assume X = Y + 20
So substitute the assumed equation into X + Y = 46
(Y + 20) + Y = 46
2y + 20 = 46
Subtract 20 from both sides :
2y = 26
Divide 2 by both sides :
y = 13

Number of hits
Number of misses

36
b) Use the total of the results to estimate the
probability of Ben of hitting the target.
Answer:
[tex]P(Hits) = 0.70[/tex]
Step-by-step explanation:
Given
[tex]Throws = 120[/tex]
[tex]Hits = 84[/tex]
[tex]Miss = 36[/tex]
See attachment for result
Required
Determine the probability of hitting the target
This calculated using:
[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]
[tex]P(Hits) = \frac{84}{120}[/tex]
[tex]P(Hits) = 0.70[/tex]
Hence, the probability of hitting the target is 0.70
