Answer:
(f ￮ g)(8) = - 6
Step-by-step explanation:
Evaluate g(8), then substitute the value obtained into f(n)
g(8) = 8 - 2 = 6 , then
f(6) = - 6
Answer:
-62
Step-by-step explanation:
Two functions are given to us , which are ,
[tex]\bf\implies f(n)= -n \\\\\bf\implies g(n)= n - 2 [/tex]
We need to find , ( f • g )(8) . So ,
⇒ ( f • g) = - n ( n - 2 )
⇒ ( f • g) = -n² + 2
⇒ (f • g) = 2 - n²
==================================
Substituting n = 8 :-
⇒ ( f • g)(n) = 2 - n²
⇒ ( f • g)(8) = 2 - 8²
⇒ (f • g)(8) = 2 - 64
⇒ ( f • g)(8) = -62 .
Hence the required answer is (-62) .Related Questions

3/5k - 5 = 7/10k HURRY
Answers
Answer:
k = -7Step-by-step explanation:
Given the expression
3/5k - 5 = 7/10k
We are to find the value of k
Cross multiply
3(10k) = 7(5k-5)
30k = 25k - 35
30k - 25k = -35
5k = -35
k = -35/5
k = -7
Hence the value of k is -7

please answer the slope of this graph
Answers
Answer:
The slope of the line = m = 2
Step-by-step explanation:
Taking two points from the line graph
(0, 0)(1, 2)Determining the slope between (0, 0) and (1, 2)
(x₁, y₁) = (0, 0)(x₂, y₂) = (1, 2)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 0] / [1 - 0]
= 2 / 1
= 2
Thus, the slope of the line = m = 2

The best player on a basketball team makes 95% of all free throws. The second-best player makes 90% of all free throws. The third-best player makes 80% of all free throws. Based on their experimental probabilities, estimate the number of free throws each player will make in his or her next 40 attempts. Explain.
Answers
Answer: See explanation
Step-by-step explanation:
The best player on a basketball team makes 95% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 95% × 40
= 95/100 × 40
= 0.95 × 40
= 38
The second-best player makes 90% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 90% × 40
= 90/100 × 40
= 0.90 × 40
= 36
The third-best player makes 80% of all free throws. The number of free throws the best player will make in his or her next 40 attempts will be:
= 80% × 40
= 80/100 × 40
= 0.80 × 40
= 32

order from least to greatest 1/3, 5/12/, 1/6, 0.25
Answers
answer:
1/6, 0.25, 1/3, 5/12
step-by-step explanation:
whenever i have to order fractions least to greatest, i put them in decimal form. so 1/3 into a decimal would be 0.3333333; 5/12 into a decimal would be 0.4166666; 1/6 would be 0.1666666; and 0.25 is already a decimal. so it'd be 1/6, 0.25, 1/3, 5/12

When substituting y = 5x + 12 into the equation 3x - 2y - 32 = 0 to solve the
system, Jun determines that the value of y is
- a negative fraction only
- a positive fraction only
- a negative integer
- a positive integer
Answers
Answer:
A negative integer
Step-by-step explanation:
3x - 2(5x+12) - 32 = 0
3x - 10x - 24 - 32 = 0
-7x -56 = 0
-7x = 56, x = -8

Rose would be saving 50 dollars after 10 months. At first Rose only had $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.
Write the equation of the line that passes through the point (1,5) and has a slope of -2.
Answers
Answer:
y = -2x + 7
Step-by-step explanation:
to write the equation to this problem, we need to find the the y intercept, or the point where the line intersects the Y axis
a slope of -2 means that for every x unit in the positive x direction (right) two y units are moved in the negative Y direction (downward)
so if we subtract (go to the left) 1x that means we would also have to add (go up) 2y, which would leave us at the point (0,7)
now, an equation for a line is written as Y = MX + B
M = slope
B = y intercept
our slope, as we said before, is -2, and we found the Y intercept, 7, so now we can construct our equation
y = -2x + 7
Answer:
y= -2x + 7

A. -2.5
B. 0.5
C. -4
D. -1
Answers
Answer:
A) -2.5
Step-by-step explanation:
You have to plug the x-value into the function.
f(x) = (1/2)x - 1
f(x) = 1/2(-3) - 1
f(x) = (-3/2) - 1
f(x) = -1.5-1

What is the slope-intercept equation of this line? A. y=-2x+6 B. y=2x+6 C.y=-1/2x+6 D.y=6x-2
Answers
Answer:
y = [tex]-\frac{4}{3}[/tex]x + 6
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
y-intercept point on the graph is (0, 6) because it's the point that's on the y-axis.
Therefore, y-intercept is 6.
Slope: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Point A: (0, 6)
Point B: (4, -2)
Slope (m) = [tex]\frac{-2 - 6}{4 - -2}[/tex]
[tex]m = \frac{-2 - 6}{4 +2}[/tex]
[tex]m = \frac{-8}{6}[/tex]
[tex]m = -\frac{4}{3}[/tex]
y = [tex]-\frac{4}{3}[/tex]x + 6
