Answer:
y = -2
Step-by-step explanation:
You substitute 2 as x, y = 6 - 4 * 2, which is y = 6 - 8 = -2.
Write an exponential function in the form y=ab^x that goes through points (0,9) and (3, 576)
Answer:
An exponential function in the form y=9(4ˣ)
Step-by-step explanation:
Step(i):-
Given that exponential function
y = a bˣ ...(i)
The equation (i) passes through the point (0,9)
9 = a (b )⁰ = a
a =9
Step(ii):-
The equation (i) passes through the point (3,576)
576 = 9(b)³
⇒ [tex]\frac{576}{9} = b^{3}[/tex]
⇒ 64 = b³
⇒ 4³ = b³
[tex](4^{3} )^{\frac{1}{3} } = (b^{3} )^{\frac{1}{3} }[/tex]
b = 4
Final answer:-
An exponential function in the form y=abˣ
An exponential function in the form y=9(4ˣ)

Answer:
D
Step-by-step explanation:
Solving the inequality
2x + 3 ≤ 5 ( subtract 3 from both sides )
2x ≤ 2 ( divide both sides by 2 )
x ≤ 1

From which store should Dylan make his purchase if he wants to get the best price per unit?
Answer:
Store 1
Step-by-step explanation:
Given
See attachment
Required
Determine the store with the best price per unit
It should be noted that the store with the best has the least price per unit.
So, we have:
Store 1
[tex]Quantity = 10\ ft[/tex]
[tex]Price = \$2.50[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]
Rate = $0.250 per feet
Store 2
[tex]Quantity = 2\ yd[/tex]
[tex]Price = \$1.85[/tex]
Convert quantity to feet
[tex]Quantity = 2 * 3ft = 6ft[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]
Rate = $0.308 per feet
Store 3
[tex]Quantity = 12\ ft[/tex]
[tex]Price = \$3.40[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]
Rate = $0.283 per feet
Store 4
[tex]Quantity = 5\ yd[/tex]
[tex]Price = \$4.00[/tex]
Convert quantity to feet
[tex]Quantity = 5 * 3ft = 15ft[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]
Rate = $0.267 per feet
From the calculations above; store 1 has the least unit rate.
Hence, store 1 has the best price per unit

I need help solving this
Answer:
Line B & C
Step-by-step explanation:
Parallel lines have the same slope.
Lines B and C have the same slope.
You can see that for both lines B and C that each time the line goes through an exact point, they line up.
Write an equation of the line that passes through (3,2) and is perpendicular to the line y= 1/3x-3
Answer:
y = - 3x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line
Which term best describes the graph of y = x - 1
A. Increasing
B. Decreasing
C. Constant
D. Positive
introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (a) Identify the population of interest and the sample in this study. (b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
The solution to this question can be defined as follows:
Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles

Answer:
Herk in a boo
Step-by-step explanation:
Solve for the value of the variable: 7x+ 10 = 4x + 16
Enter the answer
Step-by-step explanation:
7x + 10 = 4x + 16
3x + 10 = 16 (subtract 4x on both sides)
3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)

Answer:
Step-by-step explanation:
a) Since we know that y=x^3, we can plug the values in
They would be: (-2)^3, (-1)^3, (0)^3, (1)^3, and 2^(3)
Which would be -8, -1, 0, 1, and 8
b) since we know that y=x, we can plug the values in
They would be -2, -1, 0, 1, and 2 because x = y
Hope this helps! :)

Rachel has 2/3 pound of snack mix. She eats 5/12 of the snack mix. How much of the snack mix did Rachel eat?
Answer: Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.
Step-by-step explanation:
Given : Rachel has [tex]\dfrac23[/tex] pound of snack mix..
If she ate [tex]\dfrac5{12}[/tex] of the snack mix.
Then, Quantity of snack mix eaten by Rachel = [tex]\dfrac5{12}\times\dfrac23[/tex]
[tex]=\dfrac56\times\dfrac13\\\\=\dfrac{5}{18}[/tex]
Hence, Racheal ate [tex]\dfrac{5}{18}[/tex] of the snack mix.
