Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.
Valerie earns $1 per week (where x is the number of weeks) in allowance and has spent $2, for a total of y dollars.
Valerie earns $2 per week (where x is the number of weeks) in allowance and has spent $1, for a total of y dollars.
The scenario represented by the linear function y = x + 2 is given by:
Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The y-intercept is of 2, as when x = 0, y = 2.The slope is of 1, as when x changes by 2, y also changes by 2, hence m = 2/2 = 1.Thus the function is given by:
y = x + 2.
Which means that the initial amount is of $2, and increases by $1 for each unit of time, hence the correct option is:
Valerie has $2 and then earns $1 per week (where x is the number of weeks) in allowance, for a total of y dollars.

Elena wants to make a scale drawing of her bedroom. Her bedroom is a rectangle with length 5 m and width 3 m. She decides on a scale of 1 to 50. a. What would be the width and length of a scale drawing of Elena's bedroom?
Answer: Length = 10cm
Width = 6cm
Step-by-step explanation:
First and foremost, we should note that
1 meter = 100 cm.
Therefore,
Length = 5m = 500 cm
Breadth = 3m = 300 cm.
Since Elena wants to make a scale drawing of 1 to 50, then
Length = 500 cm / 50 = 10 cm
Breadth = 300 cm / 50 = 6 cm.
Therefore, the length of the scale drawing will be 10 cm and the width of the scale drawing will be 6cm.

The temperature was –5°C at 6:00 a.M. It increased 3 4 34 of a degree every hour for 6 hours. The temperature then increased 1 1 2 112 degrees every hour for 5 hours. What was the temperature at 5:00 p.M.?
Answer:
The temperature was;
6 °C
Step-by-step explanation:
Here, we want to know the temperature at 5 pm
For the first 6 hours, we have an increase of 3/4 degree per hour
so the temperature increase in the first 6 hours will be;
6 * 3/4 = 4.5 degrees
Then we had an increase of 1 1/2 degrees per hour for 5 hours
The increase after these 5 hours will be;
3/2 * 5 = 15/2 = 7.5 degrees
Total increase is 7.5 + 4.5 = 11 degrees
We subtract the initial -5 from here
So the present temperature will be;
-5 degree + 11 degree = 6 degrees celsius
How can you write the equation for a linear function if you know only two ordered pairs for the function?
Drag tiles to complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Use the two ordered pairs to find the slope, m.
Then substitute one set of ordered pairs and m into y = mx + b to solve for b
Step-by-step explanation:
If we are given two ordered pairs of a function and we need to write an equation that represents the linear function, first, what we need to do is to use the two ordered pair to find the slope, m, using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].
After getting the slope (m), find the value of the y-intercept (b), by substituting the value of one of the ordered pairs and the slope value (m) into y = mx + b.
Once the value of m and b is known, plug in the value of m and b into y = mx + b to derive the equation of the linear function.
Use the 2 ordered pairs to find the slope, m .
Then substitute m and one set of ordered pairs into y = mx + b to solve for b.
If given the 2 ordered pairs for a function, the ordered pairs can be first used to find the slope of the function.
For example
(x₁, y₁)(x₂, y₂)
m = slope = y₂ - y₁ / x₂ - x₁
The slope(m) is then substituted in the slope intercept form equation.
y = mx + b
where
m = slope
b = y-intercept
And one set of the ordered pairs is also substituted in the equation to get the value of the y-intercept(b).

Which equation below would be perpendicular to the line x=5
a. y = 1/5x
b. y = 3
c. x =2
d. y = -5x
Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!

The expression on the left side of an equation is shown below. Negative 6 x + 6 = box If the equation has an infinite number of solutions, which expression can be written in the box on the other side of the equation? –6 1 Negative 6 x Negative 6 x + 6
Answer:
The answer is -6x + 6
Step-by-step explanation:
For us to have an infinite number of solutions, then, what we have on the right hand side will be exactly what we have on the left hand side
Since we have -6x + 6 on the left hand side
To have infinite number of solutions, what we have on the right hand side will be the same
Thus, we have -6x + 6 on the second side

William is 11 years old. One day, his granddad took him and his younger brother to a basketball game. The tickets for the game were priced at $17 for adults (`a`) and $13 for children (13 years and younger) (`c`). What is the expression for the total cost of the tickets for William’s family and what was the total cost?
Answer:
43$
Step-by-step explanation: Three tickets total.
2 tickets cost 13$ =26
1 ticket 17 = 43 total
Hope this helped! God Bless!!
The total cost of the tickets for William’s family with 1 adult and 2 children is $43.
William's age = 11 years
Price for an adult = $17
Price for a child = $13
What will be the total number of tickets be bought?The total number of tickets to be bought will be 3 i.e. William, His Granddad, and William's younger brother i.e. 1 adult ticket and 2 children tickets.
Total price = price of 1 adult ticket + price for 2 children's ticket
Total price =17+2*13
Total price =17+26
Total price =$43
Therefore, the total cost of the tickets for William’s family is $43.

A bag contains green tokens and black tokens. There are 24 green tokens in the bag. The ratio of green tokens to black tokens is 8 to 5. Find the number of black tokens in the bag.
Can I have the answer please?
Answer:
There are 15 Black tokens.
Step-by-step explanation:
If the ratio is 8:5 we divide 24 by 8 to get 3. We then do 5 x 3 for the black tokens and get 15.
The number of black tokens in the bag are 15.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
In the bag, there are 24 green tokens in the bag.
And, The ratio of green tokens to black tokens is 8 to 5.
Now,
There are 24 green tokens in the bag.
And, The ratio of green tokens to black tokens is 8 to 5.
So, Number of green tokens = 8x
And, Number of black tokens = 5x
Hence, We can formulate;
⇒ 8x = 24
⇒ x = 3
Thus, Number of black tokens = 5x
= 5 × 3
= 15
Therefore, The number of black tokens in the bag are 15.
