Write the slope-intercept form of an equation of the line that passes through (a, - 4) is parallel to the graph of 4x - y = 2 y = - 1/4 * x + 4 y = 1/3 * x - 4 y = 4x - 4 D y = - 4 - 4

Answers

The first questionsanswer:

Given (0, -4), 4x - y = 7. I converted the equation into slope intercept form and I got: y = 4x - 7. Once I had gotten that I put (0, -4) and the equation into Point-Slope Form and solved it: y - (-4) = 4(x + 0),  y + 4 =  4x,  y = 4x - 4 is the slope intercept form of your equation and point :)

2. Suppose the measures of the interior angles of a convex octagon are eightnumbers, each separated by a value of 1 degree from its neighbors. Find
the measure of the second smallest angle.
118°
131°
132.5°
142°
None of these answers are correct.

Answers

Answer:  132.5 degrees  (choice C)

=====================================================

Explanation:

The interior angles are consecutive numbers such as 1,2,3,... or 7,8,9... and so on. The gap between any two adjacent neighbors is 1.

For any polygon with n sides, the interior angles add up to 180(n-2)

We have n = 8 sides so the interior angles sum to 180(n-2) = 180(8-2) = 1080 degrees.

Any octagon has its interior angles add up to 1080 degrees.

-----------------------------

Let x be the smallest angle. The next angle up is x+1. After that is x+2 and so on until we reach x+7 as the 8th angle.

Add up those 8 angles, set the sum equal to 1080 and solve for x

x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)+(x+7) = 1080

8x+28 = 1080

8x = 1080-28

8x = 1052

x = 1052/8

x = 131.5

This is the smallest angle. The next angle up or the second smallest angle is x+1 = 131.5+1 = 132.5 degrees  (choice C)

Ms. Terry's class is hosting a fundraisingchallenge. The students in her class are
divided into 4 teams. Each team has an
equal number of students. Do you have
enough information to find how many
students are on each team? Explain.

Answers

In being able to find out whether it is possible to know the number of students on each team, there simply isn't enough information to do so.

In order to find out the number of students on each team, the following formula is necessary:

= Number of students in general / Number of teams

The number of teams is 4 so the denominator is present.

We however, do not have the number of students in general so we are unable to find out the number of students in each team.

In conclusion, we do not have enough information to find out the number of students in each team.

You do not have enough information because you need to know how many students are in the class to be able to divide them into 4 equal groups we do know that it has to be a positive integer that can be evenly divided by 4

Calculate the rent of a decreasing annuity at 8% interest compounded quarterly with payments made every quarter-year for 7 years and present value $78,000.

Answers

The general Formula for a decreasing Annuity is:
P = ( ((1+i)^n -1)/(i (1+i)^n)) R
For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02

After substituting you can find value for R, rent.

Unit 4 linear equations homework 12

Answers

Answer:

There's no questions or worksheet attached.

Final answer:

This question pertains to linear equations, a topic in high school level algebra. Linear equations produce a straight line when graphed and can be solved using algebraic methods. Completing the homework might involve solving for variables, graphing the equations, or interpreting the graphs.

Explanation:

The subject of this question is about Unit 4 Linear Equations Homework 12 which falls within the scope of Mathematics, specifically in the field of algebra. A linear equation is an equation between two variables that produces a straight line when graphed out. Solving such equations involves procedures such as simplification, addition, subtraction, multiplication and division.

As for homework, it might involve solving for variables, graphing the linear equations, or interpreting such graph. For example, the equation of a line could be form such as 'y=mx+b', where 'm' is the slope of the line and 'b' is the y-intercept. One might be asked to determine the slope and y-intercept from a given equation or to write an equation given certain information.

When tackling this kind of homework, one should carefully review his/her class materials and notes. Once the concept and the procedure is clear, practice with some example problems is a great way to increase confidence and proficiency in solving linear equations.
