Answer:

The correct option is;

A vertical line can be represented using a table but not a function because the slope is undefined

Step-by-step explanation:

A function, f(x), representing a linear relationship can be presented as follows;

f(x) = m·x + c

Where;

m = The slope = Δy/Δx = (y₂ - y₁)/(x₂ - x₁)

c = The y-intercept

Whereby the line is a vertical line, x₂ = x₁ and x₂ - x₁ =

Therefore;

The slope of a vertical function, m =  (y₂ - y₁)/(x₂ - x₁) = (y₂ - y₁)/0 = ∞ from which we have;

f(x) = ∞·x + c = ∞ which is undefined and the vertical line can only be represented using a table but not a function because the slope is undefined

Answer:

D

Step-by-step explanation:

y-intercept or "b":

the line touches the y-axis at -4

slope:

the line rises 1, runs 1 every time

equation:

the y-intercept of -4 combined with the slope of 1/1 is the equivalent of

y=1x/1-4 OR in a more simplified format: D, y = x - 4

Answer: ion know i'm guessing 4

Step-by-step explanation: because it shows 8 at the top, so since it's full and it's 4,000 then that'll basically make 8 the 4000, so since 4 is half of 8 then we prolly have our answer right there

Answer:

$24.96

Step-by-step explanation:

Total number of gallons irede had in his tank = 6.4gallons

Price per gallon is $3.90

To get the cost of 6.4gallons;

If 1 gallon = $3.90

6.4gallons = $x

Cross multiply

1 * x = 3.90 * 6.4

x = 24.96

Hence Irene spent $24.96 on gas

Answer:

A is two; B is nine; C is one

Good Luck!

a) C has to be either one or zero (but I'm assuming the solution you're wanting is when C=1). This is because A+B + Whatever is carried can only be a number 0-19, meaning only a 1 can be carried to the third column.

b) if C is 1, then in the ones place, B+A must = 11

c) if the carried 1 + a + b = 10 + a, then a can be substituted and we find that b = 9; and a =2

Answer:

17 / 8

Step-by-step explanation:

sec A = [tex]\frac{1}{cos A}[/tex]

cos A = [tex]\frac{40}{85}[/tex] = [tex]\frac{8}{17}[/tex] ⇒ sec A = [tex]\frac{17}{8}[/tex]

Answer:

Solving equation [tex]13-715x=130x[/tex] we get [tex]x= \frac{1}{65}[/tex]

Step-by-step explanation:

We need to solve the equation [tex]13-715x=130x[/tex]

Combining like terms and solving

[tex]13-715x=130x\\Adding \ 715x \ on \ both \ sides:\\13-715x+715x=130x+715x\\13=845x\\Divide \ both \ sides \ by \ 845\\\frac{13}{845}=\frac{845x}{845}\\=>x= \frac{1}{65}[/tex]

So, solving equation [tex]13-715x=130x[/tex] we get [tex]x= \frac{1}{65}[/tex]

Answer:

7 days

Step-by-step explanation:

Bamboo plant A = 1.2 + 0.45d

Bamboo plant B = 0.85 + 0.5d

Where,

d = number of days

Equate the two growth

Bamboo plant A = Bamboo plant B

1.2 + 0.45d = 0.85 + 0.5d

Collect like terms

1.2 - 0.85 = 0.5d - 0.45d

0.35 = 0.05d

Divide both sides by 0.05

d = 0.35 / 0.05

d = 7 days

Plant B be taller than Plant A after 7 days

Answer:

Step-by-step explanation:

REF: 060309a

ANS:

(9,−2)

(x,y)-->(x+5,y-4)

Transformation involves changing the position of a point.

The image of the translation is (9,-2).

The point is given as:

[tex]\mathbf{A= (-2,3)}[/tex]

The image of the point is:

[tex]\mathbf{A'= (3,-1)}[/tex]

The translation rule is calculated as:

[tex]\mathbf{T = <x + 3--2,y-1-3>}[/tex]

[tex]\mathbf{T = <x + 5,y-4>}[/tex]

So, the image of (4,2) is:

[tex]\mathbf{Image = (4 + 5, 2 -4)}[/tex]

[tex]\mathbf{Image = (9, -2)}[/tex]

Hence, the image of the translation is (9,-2).

Answer:

Roman civilization lasted for 985 years.

Step-by-step explanation:

Given that Roman civilization began in 509 BC and ended in 476 A.

All we have to do is to subtract -579 from 476.

i.e.

[tex]476 - (-509)[/tex]

[tex]=476+509[/tex]

[tex]=985[/tex] years

Thus, Roman civilization lasted for 985 years.

Answer:

b=80-8t

Step-by-step explanation:

"b" represents the charge remaining

"t" represents the number of hrs that have passed.

"80" is the reference we will be subtracting the hours from.

"8" is the percentage per hour we will be subtracting

therefore, the equation b=80-8t would solve for the remaining battery after "t" number of hours.

Answer:

(x-2,y-4)

Step-by-step explanation:

Here, we want to calculate the rule for the translation

From the question, we can see that the new image was just formed as a movement of the old image by some particular units

The x-axis was move sideways while the y-axis was moved further down

The number of units is thus;

Y from 12 to 8

A movement of -4

For the x-axis

we have a movement of two units toward the left

So the rule is;

(x,y) to (x-2, y-4)

Answer:

x>-1

Step-by-step explanation:

first, you have to distribute. 12x+8-6>2x-16+8

then you have to combine like terms 12x+2>2x-8

you put the X's on one side 10x+2> -8

move the 2 to the -8 10x>-10

divide x>-1

Answer:

Number 2. x>-1

Step-by-step explanation:

4(3x+2) is 12x+8. 12x+8-6 is 12x+2.

12x+2>8+2(x-8)

2(x-8) is 2x-16. 2x-16+8 is 2x-8.

12x+2>2x-8

12x>2x-10

10x>-10

x>-1
