Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y [1st Equation]:                                                                           -10x = -7x + 6[Addition Property of Equality] Add 7x on both sides:                                   -3x = 6[Division Property of Equality] Divide -3 on both sides:                                x = -2

Step 3: Solve for y

Substitute in x [2nd Equation]:                                                                         y = -10(-2)Multiply:                                                                                                             y = 20
Answer 2
1) Substitute y for y in the equation and set them equal to each other.

-10x=-7x+6

*Combine like terms*

2) add 7x to both sides

-3x=6

*isolate x: divide by -3*

3) x=-2

Answer:

A = 100 pi cm^2

Step-by-step explanation:

A = pi(r^2)

A = pi(10^2)

A = pi(100)

A = 314.16 '

Convert to pi units.

314.16 ---> 100pi cm^2

Answer:

Half of 20 is 10(New radius)

10^2(radius squared) = 100

100pi is your next step, which is 100π cm2

Answer:

h = 0

Step-by-step explanation:

Ok, I got you.

To begin, everyone knows that y = mx + b is the equation for any slope-intercept form problem.

y = the y - value of a point

m = the slope

x = the x - value of a point

b = the y - intercept (or where the line starts)

So, you are given the slope, and you're given the y - value. But, you don't have the x - value in the second point.

That mean's you're going to have to use the first point, because you're given both the x and y values, to find the y - intercept.

Simply, plug in the y and x values where they belong.

2 = 6 (-1) + b

(Remember the 6 is the slope)

Now, solve for b.

2 = -6 + b

8 = b

Now, you know the y - intercept.

So, you can find the value of h in the second point. Since you don't know the x - value, plug in what you do know and solve for y.

So...

8 = 6 (x) + 8

(Remember 6 is the slope and 8 is the y - intercept)

Now, solve for x.

8 = 6x + 8

0 = 6x

0 = x

The value of h is 0.

If the fifth term of an arithmetic sequence is 11 and the common difference is​ 4, then the sixth term of the sequence is​ _______.

Answers

Answer:

15

Step-by-step explanation:

11+4=15

The sixth term of an arithmetic sequence with fifth and common difference of 11 and 4 respectively is 15

Arithmetic sequence formula

aₙ = a + (n - 1)d

where

a = first termd = common differencen = number of terms

Therefore,

11 = a + 4d

d = 4

Hence,

11 = a + 4(4)

11 = a + 16

a = 11 - 16

a = -5

Therefore, the sixth term is as follows

a + 5d = a₆

-5 + 5(4) = a₆

a₆ = -5 + 20

a₆ = 15

eligible according to the means test. Help the Osbornes through the steps of the means test to
see if they qualify.
Part I: What is the Osbornes' monthly income?
I
Part II: What is the Osbornes' monthly income minus monthly expenses?
Part III: What is 60 times the answer to Part II?
Part IV: Is the answer to Part III greater than or less than $10,000?
Part V: Are the Osbornes eligible for Chapter 7 bankruptcy according to the means test?

Answers

A family qualifies for bankruptcy if the difference between their monthly income and expenditure, multiplied by 60 is greater than $10,000. So, The Osbornes qualify for chapter 7 bankruptcy.

We have the following parameters:

[tex]Annual\ Income = \$66000[/tex]

[tex]Monthly\ Expenses = \$5300[/tex]

To calculate the monthly income, we simply divide the annual income by 12 (12 is the number of months in a year)

So, we have:

[tex]Monthly\ Income = \$66000 \div 12[/tex]

[tex]Monthly\ Income = \$5500[/tex]

The difference between the monthly income and the expenses is:

[tex]Difference = Monthly\ Income - Monthly\ Expenses[/tex]

[tex]Difference = \$5500 - \$5300[/tex]

[tex]Difference = \$200[/tex]

The above result multiplied by 60 is:

[tex]Product = Difference \times 60[/tex]

[tex]Product = \$200 \times 60[/tex]

[tex]Product = \$12000[/tex]

$12000 is greater than $10000

Since $12000 is greater than $10000, then they are eligible for chapter 7 bankruptcy.

Write the standard form equation (Ax + By + C =0) for a line that is perpendicular to

y= 2x + 7 and has the same y-intercept as the line y=5x - 5.

Put only the coefficients for A, B and C

Answers

Answer:

A = 1

B = 2

C = 10

Step-by-step explanation:

slope intercept form is

y = mx + b

m is the slope

b is the y-intercept

The slopes of parallel lines are negative reciprocals

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

y = 2x + 7

slope  = 2

slope of perpendicular line is the negative reciprocal of 2

slope = -1/2

y = 5x - 5

y-intercept is -5

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

slope intercept form of perpendicular line

using slope = -1/2 and y-intercept  = -5

y = -(1/2)x - 5

Change to standard form:

multiply both sides by 2

2y = -x - 10

Add x + 10 to both sides

x + 2y + 10 = 0

Therefor

A = 1

B = 2

C = 10

arithmetic sequences

Answers

Answer:

For 1, you'd have 14, 7, 0, -7

Step-by-step explanation:

Remember arithmetic sequences are adding the same thing (the difference) over and over and over. So in this case, you have the following:

1st blank: 14 + d

2nd blank: 1st blank + d OR (14 + d) + d = 14 + 2d

the -7 then is the 2nd blank + x OR [(14 + d) + d] + d

So you are adding 3d to the 14 to get to the -7. Set that up as the equation:

14 + 3d = -7.

When you solve for d, you get -7. That's what you'll add to 14 to get the first number, then add it again to get the second, etc.

The coefficient in front of d will always be one more than the number of spaces since you are adding the difference to find each blank IN ADDITION TO the last number in the sequence. So #4 would be setup like this:

2 + 5d = 57
