Answer:
$6.3
Step-by-step explanation:
Original price = $18
Percentage Discount = 65%
Discount = 18*65% = 18*0.65 = $11.7
Sale Price = Original price - Discount
= $18 - $11.7
= $6.3
Answer:
A
Step-by-step explanation:
From what we have , it is expected that the parent function is a v-shaped graph that starts from the origin
The expected equation parent function should be;
y = |x|
Now, moving on, the transformed function is 1/2 of the parent function
This shows a direct compression of the initial partner function
So, it is expected that the transformed function is more compressed compared to the initial parent function
so, the correct choice of answer here is first option
Answer:
The constant of variation for the subscription cost based on the number of weeks is 4
Step-by-step explanation:
The equation of a line in intercept form is given by:
y = mx + c
Where c is the intercept on the y axis and m is the slope of the line which is constant.
In this problem, we are asked to find the constant of variation, this can be determined from the slope because the slope is the constant of variation.
The Ferry Ride Cost with Number of Persons on the x-axis and Total Cost in dollars on the y-axis. The equation of a line passing through two points is given by:
![y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29)
The points are (1, 2) and (5, 8), therefore using:
![y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y-2=\frac{8-2}{5-1}(x-1)\\ y-2=4(x-1)\\y-2=4x-4\\y=4x-4+2\\y=4x-2](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%28x-x_1%29%5C%5Cy-2%3D%5Cfrac%7B8-2%7D%7B5-1%7D%28x-1%29%5C%5C%20y-2%3D4%28x-1%29%5C%5Cy-2%3D4x-4%5C%5Cy%3D4x-4%2B2%5C%5Cy%3D4x-2)
Comparing y = 4x -2 and y = mx + c, m = slope = 4
The constant of variation for the subscription cost based on the number of weeks is 4
Answer:
x = the price of one coffee mug.
n = number of coffee mugs sold
115.50 = x × n
n = 115.50÷ x

Answer:
x = 48
Step-by-step explanation:
The sum of the angles in a pentagon is 540°, so you have ...
90° +100° +110° +2x° +3x° = 540°
5x = 240 . . . . . . . divide by °, subtract 300
x = 48 . . . . . . . . . divide by 5

<em>Additional comment</em>
The sum of angles in a convex n-gon is (n -2)×180°. For a pentagon, that's 3×180° = 540°.
