A computer store buys a computer system at cost of 572.40 cents the selling price was first at 9:54 but then the store was advised at 20% markdown on the system answer parts a and b

Answer:

A, B, & D

Step-by-step explanation:

A: Linear functions are often written in point-slope form, y=mx+b.

B: The rate of change in linear functions is always a constant slope, the m value.

C: The initial value of a linear function could be zero. It depends on the line.

D: It makes sense that the graph of a linear function is a line.

E: A vertical line is not a function. You can do the vertical line test: if a vertical line were to hit more than one point at a single x-value, the line is not a function.

Step-by-step explanation:

5-3= 2

-5-5= -10

Answer:

y - 5 = - [tex]\frac{3}{5}[/tex](x + 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Given

5x = 3y , that is

3y = 5x ( divide both sides by 3 )

y = [tex]\frac{5}{3}[/tex] x ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{3} }[/tex] = - [tex]\frac{3}{5}[/tex] and (a, b) = (- 5, 5), then

y - 5 = - [tex]\frac{3}{5}[/tex] (x - (- 5) ), that is

y - 5 = - [tex]\frac{3}{5}[/tex] (x + 5) ← equation of perpendicular line

Answer

2/3, 7/10, 11/15

Step-by-step explanation:

Answer:

[tex]x^{4}[/tex] + x² + 1

Step-by-step explanation:

One way is to divide using Synthetic division

1 |  1    - 1    1    - 1    1    - 1

     ↓      1    0     1    0     1

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

     1      0     1     0    1    0 ← remainder

Since remainder is 0 then (x - 1) is a factor of the polynomial

The quotient is of degree 1 less than the dividend, that is

quotient = [tex]x^{4}[/tex] + x² + 1

Answer:

[tex]\boxed{x^4 + x^2 + x}[/tex]

Step-by-step explanation:

[tex]\frac{x^5 - x^4 + x^3 -x^2 + x - 1}{x - 1}[/tex]

[tex]= \frac{(x - 1)(x^4 + x^2 + x)}{x - 1}[/tex]

[tex]= x^4 + x^2 + x[/tex]

Answer:

x^7/y^7 (top right)

Step-by-step explanation:

Exponents are added together when multiplied, so it would equal x^7y^-7, but to get rid of the negative, the y would become the denominator in a fraction.

Answer:

x^7/y^3

Step-by-step explanation:

x^3+y^2+x^4+y^-5

re-arrange

x^4+x^3+y^-5+y^2

x^4+3+y^2-5

x^7+y^-3

let the minus(-)with the 3 be taken away

hence;

x^7/y^3

hence 3 is then possitive

Answer:

x=4

Step-by-step explanation:

3(x+2) = 2(x+5)

Distribute

3x+6 = 2x+10

Subtract 2x from each side

3x-2x+6 = 2x-2x+10

x +6 = 10

Subtract 6 from each side

x+6-6 = 10-6

x = 4

Answer:

x = 4

Step-by-step explanation:

Original Equation:

3(x + 2) = 2(x + 5)

Use distributive property

3 · x = 3x

3 · 2 = 6

Your equation should look like this now:

3x + 6 = 2(x + 5)

Use distributive property for the other side

2 · x = 2x

2 · 5 = 10

Your equation:

3x + 6 = 2x + 10

Subtract 6 from both sides

3x = 2x + 4

Subtract 2x from both sides

1x = 4

Divide both sides by 1

x = 4

Answer:

Lines J, K, and M are all parallel to each other.

Step-by-step explanation:

Parallel lines are two or more lines that are on the same plane but never intersect. Because they don't intersect they the same distance apart no matter what point you measure from on the line. Line N is the transversal for lines J, K, and M.

The time it will take for Teri's account to earn $6000 = 87 years

The total amount of money invested by Teri ( p) = $2500

The interest rate of the investment (r) = 2.75%

The simple interest is ( I) = $6000

Therefore the time to generate the interest of $6000

[tex] \frac{i \times 100}{p \times r \: } = t[/tex]

Therefore, time =

[tex] \frac{6000 \times 100}{2500 \times 2.75} [/tex]

[tex] \frac{600000}{6875} [/tex]

=87 years.

Therefore, the time it will take for Teri's account to earn $6000 = 87 years
