Answer:
y = - 4
Step-by-step explanation:
x = - 1 is the equation of a vertical line parallel to the y- axis
The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (8, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of perpendicular line
Answer:
(B)72 fluid ounces
Step-by-step explanation:
To convert cups to fluid ounces, Sari wrote the equivalent ratios.
![\dfrac{8 \text{ fluid ounces}}{1\text{ cup}} =\dfrac{\text{? fluid ounces}}{9\text{ cups}}](https://tex.z-dn.net/?f=%5Cdfrac%7B8%20%5Ctext%7B%20fluid%20ounces%7D%7D%7B1%5Ctext%7B%20cup%7D%7D%20%3D%5Cdfrac%7B%5Ctext%7B%3F%20fluid%20ounces%7D%7D%7B9%5Ctext%7B%20cups%7D%7D)
Let the question mark be represented by x.
We then have:
![\dfrac{8 \text{ fluid ounces}}{1\text{ cup}} =\dfrac{\text{x fluid ounces}}{9\text{ cups}}\\$Cross multiply\\x \times 1 = 8 \times 9\\x=72$ fluid ounces](https://tex.z-dn.net/?f=%5Cdfrac%7B8%20%5Ctext%7B%20fluid%20ounces%7D%7D%7B1%5Ctext%7B%20cup%7D%7D%20%3D%5Cdfrac%7B%5Ctext%7Bx%20fluid%20ounces%7D%7D%7B9%5Ctext%7B%20cups%7D%7D%5C%5C%24Cross%20multiply%5C%5Cx%20%5Ctimes%201%20%3D%208%20%5Ctimes%209%5C%5Cx%3D72%24%20fluid%20ounces)
We conclude that there are 72 fluid ounces in 9 cups.
Answer:
0.2
Step-by-step explanation:
y^t=3^2=9
x/y^t=2/9=0.2
r-12
substitute in r=7
so 7-12 = -5
Answer:
Loss %age = 25%
Step-by-step explanation:
<u><em>Cost Price of Item</em></u> = 250,000/-
<u><em>Loss </em></u>= 1/4 = 0.25 of 250,000
=> 62,500 /-
<u><em>%age Loss</em></u> = ![Loss*100/Cost Price](https://tex.z-dn.net/?f=Loss%2A100%2FCost%20Price)
=> 62,500 * 100 / 250,000
=> 6,250,000/250,000
=> 25 %
