13) = 72/360 x 2π x 25

The function f(x) = 1.50x – 30 gives the amount of money Amelia has to spend each week for x school lunches, after taking money
Naya [18.7K]
To find the inverse, switch the x and y, and then solve for y (f(x) is the same as y)

So we get:
x=1.50y-30 (add 30 to both sides)
x+30=1.50y (divide both sides by 1.5)
x/1.5+30/1.5=y
y=x/1.5+20

Hope this helps

What is the equation of the line that passes through (-5, 7) and is parallel to the line y = 4x + 5?
Marysya12 [62]

Answer:

y=4x+27

Step-by-step explanation:

If a line is parallel, it would have the same slope, so you already have that.

Now, you need the y-intercept of the second line. You already have one point, so use that point and the slope to find the y-int. What you can do (since you know you have to go up 4 and over 1, add a 1 to the -5 until you get to zero. your y-int would be 7+20 since you've gone up 5x4)

your final answer (i think) should be y=4x+27, but I could be wrong :))

Choose the expression that best represents the phrase below.
Arada [10]

20 more than the price of the meal is 20+p. Option-B is correct.

Given that,

The expression we have to get from 20 more than the price of the meal is.

Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both. There are four types of mathematical operations: addition, subtraction, multiplication, and division.

Take the price of the meal as p.

20 more than the price of the meal is 20+p.

Therefore, 20 more than the price of the meal is 20+p. Option-B is correct.
