The value of x when f(x) = 1 is x = 2.
What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given:
The function,
f(x) = 3x – 5.
Solving for x when f(x) = 1,
1 = 3x - 5
3x = 6
x = 2
Therefore, the value is x = 2.

Kaleb can skateboard 75 feet in 25 seconds. How far can he skateboard in 3.25 minutes?
Answer:
585 Feet
Step-by-step explanation:
First, you have to consider how much seconds in a minute. 60.
Then, multiply 75 feet to make it match to 60 seconds. So 60/25. You get 2.4. You multiply 2.4 by 75 to get 180 feet per minute.
Finally, you multiply 180 by 3.25, as it is 3.25 minutes.
what is 8.546 rounded to the nearest tens?
Answer:
10
Step-by-step explanation:
In this problem we need to round off 8.546 to the nearest tens. 8 is in ones place, 5 is in tenths place, 4 is in hundredths place and 6 is in thousandth place.
8 falls between 5 and 10 on the number line. It is less than 5 and more than 10. When it is rounded off to nearest tens it can be given by 10.
Use the substitution method to solve the system of equations. Choose the
correct ordered pair.
y = 4x - 2
y = x + 13
A. (1, 13)
B. (0, -2)
C. (5, 18)
D. (4,-2)
Answer:
c
Step-by-step explanation:
just plug each coordinates
5=x
18=y
if its tru for both then thats the answer
Answer:
5,8
Step-by-step explanation:
y=4x-2-----(i)
y=x+13----(ii)
Equating equation i and ii we get,
[tex]4x - 2 = x + 13[/tex]
[tex]4x - x = 13 + 2[/tex]
[tex]3x = 15[/tex]
[tex]x = 3[/tex]
[tex]substitutin \: the \: value \: of \: x \: in \: equation \: (i)[/tex]
[tex]y = 4x - 2[/tex]
[tex]y = 4 \times 5 - 2[/tex]
[tex]y = 20 - 2[/tex]
[tex]y = 18[/tex]

A bag contains 26 tiles, each with a different letter of the alphabet written on it. You choose 3 tiles from the bag without looking. What is the probability that you chose tiles with the letters A,B,C?
Ps: don’t text me only if u know the answer that’s it
Answer:
for each letter 1 /26 is the probability
Step-by-step explanation:
probability = no. of events / no. of outcome
probability for tile A
= no. of events / no. of outcome
= 1 / 26
probability for tile B
= no. of events / no. of outcome
= 1 / 26
probability for tile C
= no. of events / no. of outcome
= 1 / 26

Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. The shaded area represents the proportion of pieces of pie that have more than:__________
Answer:
Step-by-step explanation:
Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.
Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the raw score is below the mean. The z score is given as:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Given that: μ = 350 calories, σ = 20 calories, x > 375
[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{375-350}{20}=1.25[/tex]
From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories
From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)

A circle has a radius of 3.93 inches. Using the correct number of significant digits, find the circumference and the area of the circle.
The circumference is ____ in.
The area is ____ in.
Answer:
The circumference is 24.69 in.
The area is 48.52 in.
Step-by-step explanation:
Circumference rule => Cf=2πrSo, Cf=2π(3.93)=24.69in
Area rule => A=πr^2So, A=π(3.93)^2=48.52in

A trianglar carpet is laid in a square room of side 12m, if the base of the carpet is 10m and the height is 8m, calculate the area of the floor uncoverd
◈ Area of square room :
[tex]:\implies\sf\:A_s=(side)^2[/tex]
[tex]:\implies\sf\:A_s=(12)^2[/tex]
[tex]:\implies\bf\:A_s=144\:m^2[/tex]
◈ Area of triangular carpet :
[tex]:\implies\sf\:A_t=\dfrac{1}{2}\times base\times perpendicular[/tex]
[tex]:\implies\sf\:A_t=\dfrac{1}{2}\times 10\times 8[/tex]
[tex]\:\implies\sf\:A_t=\dfrac{1}{2}\times 80[/tex]
[tex]:\implies\bf\:A_t=40\:m^2[/tex]
◈ Uncovered area of room :
[tex]:\implies\sf\:\Delta A=A_s-A_t[/tex]
[tex]:\implies\sf\:\Delta A=144-40[/tex]

Blueberries cost 4.99 a pound. Diego paid 14.95 for his blueberries. How many pounds did he buy?
Answer:
The answer is 3.
Step-by-step explanation:
The equation would be: x = 14.95 divided by 4.99, rounded to the nearest one:
14.95 divided by 4.99 = 2.99599...
Normally, I would not round the number to the nearest digit in problems like these, but 2.99599 is quite close to 3, so this might be an exception.
Anyways, that's how I got my answer.
Hope this helped.
Why is the answer for letter b 9?
Answer:
Take a look at the 'proof' below
Step-by-step explanation:
The graph of the function g(x) is similar to that of the function f(t). The local minimum, local maximum, absolute minimum, maximum etc... of 'x' is always the closest x-intercept of the graph of f(t).
Let's check if this statement is right. The two local minimum(s) of the function f(t) occurs at x = 2, and x = 6. The two local maximum(s) occur at 1/4 and 4. As you can see the maximum / minimum of the function g(x) is always an x-intercept, x = 3, x = 7.
For part (b) the absolute maximum value of the function f(t), is 8. The closest x-intercept is 9, which is our solution.
Step-by-step explanation:
From x=0 to x=1, the function is above the x-axis, so the area is positive.
From x=1 to x=5, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
From x=5 to x=9, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.
Since the area increases in each interval, the area is a maximum at x=9.
Omar's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs $4.10 Omar per pound, and type B coffee costs $5.30 per pound. This month, Omar made 141 pounds of the blend, for a total cost of $640.50. How many pounds of type A coffee did he use?
Hey there! I'm happy to help!
Let's use the variables A and B to represent the number of pounds used of types A and B.
4.10A+5.30B=640.50
A+B=141
Let's rearrange the bottom equation to solve for B.
A+B=141
Subtract A from both sides.
B=141-A
We can put this value of B into the first equation to solve for the number of pounds of type A Omar used.
4.10A+5.30(141-A)=640.5
We use distributive property to undo parentheses.
4.10A+747.3-5.3A=640.5
We combine like terms.
-1.2A+747.3=640.5
Subtract 747.3 from both sides.
-1.2A=-106.8
Divide both sides by -1.2
A=89
Omar used 89 pounds of type A coffee in this month's blend.
Have a wonderful day! :D
