The value of each scarf from the sales will be $4.50.
Since Lucy spent $10.50 of her earnings on a used sweater and she had $7.50 remaining, the total amount that she made from the sales will be:
= $10.50 + $7.50
= $18.00
Since she sold 4 scarves, the cost of each scarf will be:
= $18.00 / 4
= $4.50
Therefore, the value of each scarf will be $4.50.

Write the equation of the vertical line that passes through the point (-4,-2).
Find the value of x in the figure below:
Answer:
x = 25
Step-by-step explanation:
The interior angle adjacent to the 123° angle is supplementary to it.
Its measure is 180° - 123° = 57°
The sum of the measures of the interior angles of a polygon is
(n - 2)180° = (4 - 2)180° = 2(180°) = 360°
3x + 7 + 96 + 5x + 57 = 360
8x + 160 = 360
8x = 200
x = 25

how do I determine what a function is for a line graph
Answer: Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Answer:
3.46 pounds6.92 pounds13.84 poundsStep-by-step explanation:
The most accurate ratio of pounds to dollars will be found using the given numbers that have the most significant figures. Those are found on the last row of the table:
pounds/dollar = 34.60/50 = 0.692
To find the other table values, multiply the dollar amounts by this constant of proportionality. The problem statement tells you to round the result to hundredths.
$5 ⇒ 5.00 × 0.692 = 3.46 pounds
$10 ⇒ 10.00 × 0.692 = 6.92 pounds
$20 ⇒ 20.00 × 0.692 = 13.84 pounds
_____
You can also fill in the table by recognizing that $5 is one tenth of $50, so the number of pounds will be one tenth of 34.60 = 3.46. Then each of the following rows doubles the amount on the previous row.
Factor the following polynomial x^2-9
Answer:
(x+3)(x-3)
Step-by-step explanation:
We know that [tex](a+b)(a-b)=a^2+b^2\\[/tex]
So, here we have x² and 9, which can be written as 3².
Therefore, we can have x=a and 3=b
So we get
(x+3)(x-3)
To check that we are correct, we can expand the brackets:
x²-3x+3x-9
=x²-9
Assume that adults have IQ scores that are normally distributed with a mean of ?=100 and a standard deviation ?=20. Find the probability that a randomly selected adult has an IQ less than 140.
Answer:
The probability that a randomly selected adult has an IQ less than 140 is 0.9772
Step-by-step explanation:
Given:
Standard deviation: σ=20
Mean: μ=100
P(X<140)=?
Calculate:
normalcdf(lower,higher,μ,σ) = normalcdf(0,140,100,20) = 0.9772496509 ≈ 0.9772 ≈ 97.72%
A toy rocket is launched from a platform 33 feet above the ground at a speed of 83 feet per second. The height of the rocket in feet is given by the polynomial −16t2 + 83t + 33, where t is the time in seconds. How high will the rocket be after 3 seconds?
a. 2586 feet
b. 234 feet
c. 138 feet
d. 105 feet
Answer:
c. 138 feet
Step-by-step explanation:
h(t) = −16t^2 + 83t + 33
At3 seconds
h(3) = -16(3^2) + 83(3) + 33
h(3) = -16(9) + 249 + 33
h(3) = -144 + 249 + 33
h(3) = 138
c. 138 feet

x + 4y = 23
-2x + 3y = -2
Answer:
(x, y) = (7, 4)
Step-by-step explanation:
I find a graphing calculator to give a solution quickly and easily.
(x, y) = (7, 4)
__
Here, we can solve the first equation for x, then substitute into the second.
x = 23 -4y
-2(23 -4y) +3y = -2 . . . . . substitute for x
-46 +8y +3y = -2 . . . . . eliminate parentheses
11y = 44 . . . . . . . . . . . collect terms
y = 4 . . . . . . . . . . . . divide by the coefficient of y
x = 23 -4·4 = 7 . . . . use the expression for x to find x
(x, y) = (7, 4)
