What is the equation of the line that passes through (0, 3) and is perpendicular to y = = x + 5?
5
Answers
D
when you're doing a perpendicular line, you want the exact opposite of your original.
take, for example, a line with a slope of 2. the line perpendicular to it would have a slope of -2.
With a fraction, its pretty tricky. Let's say you have 2/7 as your slope. you want the EXACT opposite so
First, make it negative
Next, flip it around.
You get -7/2 as your slope perpendicular to your original line.
For the point passing through, if x equals 0, y equals your y intercept. your y value is 3 therefore b (y-intercept) equals 3.
For questions that are less simple than a plain y-intercept, (which you are guaranteed to encounter in the future) you simply input the y and x values into your y=mx+b equation.
Say we have an example here of a line with a slope of 4, and it passes through (5,-3). We have to find our B, or y-intercept, so we input the values.
-3=4(5)+b
Now, simplify
-3=20+b
-23=b
Your example equation is now y=4x-23

We are given that:
variables x and y vary directly, this means that:
y = kx where k is the constant of proportionality
Now, we are also given that:
y = 45 at x = 40.
We will use these values and substitute in the above relation to get k as follows:
y = kx
45 = 40k
k = 45/40 = 9/8 = 1.125
Based on the above calculations, the equation that relates x and y is:
y = 1.125x

7 weeks * 7 days per week = 49 days49 days * 2 meals per day = 98 total meals98 meals * 31 grams per meal = 3038 grams after 7 weeksAnswer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
