Write the function for the graph.
A. f(x)= 4•(2)^x
B. f(x)= 2•(4)^x
C. f(x)= 8•(4)^x
D. f(x)= 4•(8)^x
A) f(x) = 4•(2)^x
Step-by-step explanation:When substituting in the values of x and y into the functions, the only function that works for both (0,4) and (1,8) is A.
8 = 4•(2)^1 = 4 x 2 = 8
4 = 4•(2)^0 = 4 x 1 = 4

11. Commercial jets fly between 30,000 ft and 36,000 ft. About how many hours of growing could
pass before the beanstalk might interfere with commercial aircrafts? Explain how you got your
answer
An exponential function is a function that increases rapidly as the time increases.
The number of hours that passes before the magical beanstalk interferes with commercial flight is approximately 9.384 hours.Reasons:
The function that gives the height of a beanstalk is presented as follows;
b(t) = [tex]3^t[/tex]
When the height is 30,000 ft., we have;
30,000 = [tex]3^t[/tex]
㏑(30,000) = t·㏑(3)
[tex]\displaystyle t = \mathbf{\frac{ln(30,000)}{ln(3)}} \approx 9.384[/tex]
The time it would take the beanstalk to grow 30,000 ft., t ≈ 9.384 hours
Similarly, the time it would take the beanstalk to grow to 36,000 ft. is found as follows;
[tex]\displaystyle t_{36,000} = \mathbf{\frac{ln(36,000)}{ln(3)}} \approx 9.55[/tex]
The time it would take the beanstalk to grow 36,000 ft., t ≈ 9.55 hours
The number of hours it will take the beanstalk to grow to 30,000 feet at
which it might interfere with commercial aircrafts is 9.384 hours.

Answer:
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.
What is the solution for the system of equations? Use the substitution method to solve. 2x+y=20−5y=−6x+12 Enter your answer by filling in the boxes. ( , )
Answer:
(7, 6 )
Step-by-step explanation:
2x + y = 20 ( subtract 2x from both sides )
y = 20 - 2x → (1)
- 5y = - 6x + 12 → (2)
Substitute y = 20 - 2x into (2)
- 5(20 - 2x) = - 6x + 12 ← distribute parenthesis on left side
- 100 + 10x = - 6x + 12 ( add 6x to both sides )
- 100 + 16x = 12 ( add 100 to both sides )
16x = 112 ( divide both sides by 16 )
x = 7
Substitute x = 7 into (1)
y = 20 - 2(7) = 20 - 14 = 6
solution is (7, 6 )

The organizers of a conference needs to prepare at least 200 notepads for the event
and have a budget of $160 for the notepads. A store sells notepads in packages of 24
and packages of 6.
24x + 6y > 200
This system of inequalities represent these constraints:
(16x + 5.40y = 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160
Inequalities shows the non equal comparison of numbers or expressions.
Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads
Since the organizers need to do at least 200 notepads, hence:
24x + 6y > 200
Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:
16x + 5.40y ≤ 160
The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Given f(x)=2x+1 and g(x)=7-x. Find g(f(x)).
Answer:
f(g(x)) = 2(7 - x) + 1
Step-by-step explanation:
f(x) = 2x + 1
g(x) = 7 - x
The question in the picture itself says to find f(g(x)) so i'll find that instead
f(g(x)) = 2(7 - x) + 1
f(g(x)) = 14 - 2x + 1
f(g(x)) = -2x + 15

To make some additional money, Vanessa began to
walk her sister's dog in order to help the dog lose
weight. Each week, the dog lost 0.2 pounds of weight
from walking with Vanessa. If the dog's starting weight
was 40 pounds, find the number of weeks that it will
take for the dog to weigh 38 pounds.
write an equation and isolate the variable.
Answer:
10 weeks
Step-by-step explanation:
Initial weight: 40
1 week = 0.2 lbs lost
40 - 38 = 2 lbs lost (goal)
x = number of weeks
0.2*x = 2
0.2x = 2
x = 10

Answer:
Step-by-step explanation:
can someone help me please, this is so stressful:/
Answer:
x=2
Step-by-step explanation:
To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.
10x - 3 = 17
(Add 3 to both sides)
10x = 20
Now isolate x (since 10x is really 10 * x, you divide)
10x=20
x=2
This is how you would solve to get the solution.

Can anyone help me with this please I really need help with this rq .
Answer:
Step-by-step explanation:
g(x) = ax - b
-76 = 27a - b
-79 = 28a - b Subtract
3 = -a Multiply both sides by -1
a = -3
g(x) = -3x - b
-85 = -3*30 - b
-85 = - 90 - b Add 90 to both sides
90-85 = - b Combine
5 = - b Multiply both sides by - 1
-5 = b
g(x) = -3x - b
g(x) = -3x - (-5)
g(x) = - 3x + 5
