Answer:
D. y²/5² - x²/8² = 1
Step-by-step explanation:
A and B are both incorrectly oriented, and D is the only hyperbola that contains the points (0,5) and (0,-5).
Verification (0,5) and (0,-5) are in the hyperbola:
First replace x and y with corresponding x and y values (We will start with x=0 and y=5)
Then simplify.
If the result is an equation (where both sides are equal to each other) then the original x and y values inputted are valid. The same is true with x and y inputs x=0 and y=-5, or any other point along the hyperbola.
Answer:
-5/3
Step-by-step explanation:
Parallel lines are lines which have the exact same slope but different y-intercepts. We can find the slope by converting to slope-intercept form, y=mx+b from standard form.
We convert by using inverse operations to isolate y.
5x+3y=7
5x-5x+3y=7-5x
0x+3y=-5x+7
3y=-5x+7
.
The slope is -5/3. SInce parallel lines have the same slope, the slope for a parallel line will be -5/3.
Answer:
250 readers
Step-by-step explanation:
1. 4% = 10
2. 100% = 250
a. 4% x 25 = %100
b. 10 x 25 = 250
I hope this helps!
Answer:
the slope is over 3 then down 3 or 3/-3
step explanation: first find the y-intercept (9) then normal you just count the number of spaces over or back then up or down
Profit = revenue - expenses
250 = 25x - (12x + 60)
250 = 25x - 12x - 60
250 = 13x - 60
250 + 60 = 13x
310 = 13x
310/13 = x
23.85 = x....so she would have to sell 24 purses
