Equation: y=20x+450

Use Desmos to graph it
Luda [366]3 years ago
5 0

Answer:

y=-20x+450

Step-by-step explanation:

Since Lori has 450$ initially, this can be modeled as our y-intercept of our function, or the <em>b </em>in y=mx+b. Since she's withdrawing 20$ a month to pay for the membership, she's losing 20$, which is why the 20 is negative in the equation. Let <em>x</em> be any amount of months, and <em>y</em> will be the balance of Lori's account at that month <em>x</em>.

Which percent is equal to the given fraction?
Gemiola [76]
D) 60%. an easy way to do this would be to multiply the denominator and the numerator by the same thing to make the denominator equal 100, and the numerator is the percent. For example, this question, how many time can 5 go into 100? 20 times. multiply 20 by 3, because what you do to the denominator you have to do to the numerator; so 20 x 3 = 60, 60%.

3/8, multiply by 12.5, since 8 goes into a hundred 12.5 times, to get 8 x 12.5 = 100 and 3 x 12.5 = 37.5, 37.5%
