If x is a number that is 7 more than y, how do you express x as a function of y?

Answers

Answer 1

Answer: Hi Mella,

So we basically have:
⇒ x = 7 + y

In order to write this in terms of y, then basically we just have to solve for y. To do this, let's look at the equation again to see how we can get y by itself.

⇒ x = y + 7

If we subtract 7 from both sides, we now have

⇒ x - 7 = y which is the same as y = x - 7.

x is now expressed as a function of y.

-Hope this helps!

Answer 2

Answer: I think that it's x=7+y

The line of best fit is reasonable because it goes through the largest cluster of points. The line of best fit is not reasonable because it does not go through any points. The line of best fit is not reasonable because it has more points below it than above it.

How many ways can a gymnastics team of 4 be chosen from 9 gymnasts?

Answers

You have 9 gymnasts and want to make a team of 4. Say one out of the nine is chosen; eight are left. Take one, then seven, and two more can be chosen. Keep doing this and your team is full. So, it's 9*8*7*6 which equals 3,024, since order doesn't matter.

Answer:

3,024 in not correct...it's 126

In a quadrilateral, three of the angles are obtuse. Which of the following could not be the angle measure of the fourth angle?20°
40°
60°
90°

Answers

If an angle it is obtuse it is between 90 and 180.

Angles in a quadrilateral add up to 360.

Therefore 3 obtuse angles must add up to AT LEAST 273 and if you then added the 90 it would get you to 363 which is too large so it cant be 90 :)

Margaritas is a very popular restaurant. Occasionally, the restaurant provides lunch and/or dinner for a local charity house. Each lunch costs $6.50. Each dinner costs $10.25. The restaurant's expenses for providing the meals cannot exceed $1,183 per trimester. If x represents the number of lunches and y represents the number of dinners, what domain best fits the situation

The y would = 115.4 and the x would = 182

Talia wants to write the equation of the graphed line in point-slope form. These are the steps she plans to use: Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
Step 4: Substitute those values into the point-slope form. y – y1 = m(x – x1) y – 3 = (x – 1) Which of Talia’s steps is incorrect? Step 1 is incorrect because it uses a point that is not on the line. Step 2 is incorrect because it uses a point that is not on the line. Step 3 is incorrect because it shows an incorrect ratio of the slope.
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

Answers

From the steps Talia chooses to find the equation of the line, we shall evaluate the incorrect step as follows:
Step 1:
Choose a point in the line such as (2,5)
Step 2:
Choose another point on the line, such as (1, 3)
step 3:
Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is.
(5-3)/(2-1)=2/2=1
step 4:
Substitute those values into the point-slope form
y-y1=m(x-x1)
y-3=2(x-1)
y=2x+1
Thus the answer is:
Step 4 is incorrect because it shows an incorrect substitution of (1, 3) into the point-slope form

just took the test the right answer is step 3 is incorrect
