Answer:

The answer to the far left/the Blue Answer.

Step-by-step explanation:

The reason why is because if 1 magazine was the price of $5, that would mean that the total of the erasers AND the magazine equals 25 dollars, as said in the statement. This means that when subtracting 5 dollars from 25 dollars, there are 20 dollars left. This means that if there were 4 erasers, that means that 20 dollars divided 4 erasers equals 5 dollars. This means that each eraser costs 5 dollars, making the Blue Answer/Statement true.

Answer:

5+4x=25

Step-by-step explanation:

You already know you bought 1 $5 magazine so that is the constant. And the question asks how many erasers you bought to equal $25. So to write the equation you know it equals 25 and the 5 is constant, if each eraser is $4 then the x goes with the 4 making it, 5+4x=25

Which of the following is written as a rational function? a. G(x)=-4x b. P(x)=7x 1 c. F(x)=x-5/3x d. Q(x)=x^2 6x-3.

slavikrds [6]

The function can be expressed as a rational function is $\rm\dfrac{x-5}{3x}$ .

We have to determine

Which of the following is written as a rational function?

According to the question

A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.

A rational function can be expressed as;

$\rm Rational \ function =\dfrac{p(x)}{g(x)}$

Then,

The required rational function is expressed as;

$\rm Rational \ function =\dfrac{p(x)}{g(x)}$

Where p(x) is (x-5) and g(x) is 3x.

Therefore,

The function is,

$\rm Rational \ function =\dfrac{x-5}{3x}$

Hence, the function can be expressed as a rational function is $\rm\dfrac{x-5}{3x}$ .

You were billed $17.60 for water usage at a rate of $0.55 per gallon. Three choices are correct ways to calculate the the number

nalin [4]

We know that total bill = rate per gallon times numbers of gallons used

So 17.60 = 0.55 times g

which get match to option (a) this is correct .

Now if we divide both sides by 0.55 we would be getting :

17.60 / 0.55 = g which is slightly different than option (b) ( because it is 55 in option b but actually it should be 0.55) so this one is incorrect .

let us now come back to option (a) 17.6 = 0.55 g

if flip the sides it becomes 0.55g = 17.6 which is same as option c option c is also correct .

Let us now divide both sides of option a by g^2 which makes it

17.6/ g^2 = 0.55 /g or 0.55/g = 17.6 /g^2 which matches only left side of option d but not right side of it so this is also not a correct option

Answer : only (a) and c are correct answer .

Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line.

Harrizon [31]

Answer:

Equation of the line that passes through the given point and is (a) parallel is: $\mathbf{y=-2x+11}$

Equation of the line that passes through the given point and is (b) perpendicular is: $\mathbf{y=\frac{1}{2}x+1}$

Step-by-step explanation:

We need to Write an equation of the line that passes through the given point and is (a) parallel and (b) perpendicular to the given line.

First we will find slope of the line given in graph

The slope can be found using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have points (1,6) and (2,2)

Slope is:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2-6}{2-1}\\Slope=\frac{-4}{2}\\Slope=-2$

Part a)

Write an equation of the line that passes through the given point and is (a) parallel

When the lines are parallel, they have same slope. So, slope of required line: m = -2

Using slope m =-2 and point(4,3) we can find y-intercept b

$y=mx+b\\3=-2(4)+b\\3=-8+b\\b=3+8\\b=11$

The equation of line will be:

$y=mx+b\\y=-2x+11$

Equation of the line that passes through the given point and is (a) parallel is: $\mathbf{y=-2x+11}$

Part b)

Write an equation of the line that passes through the given point and is (b) perpendicular

When the lines are perpendicular they have opposite slope. So, slope of required line: m = 1/2

Using slope m =1/2 and point(4,3) we can find y-intercept b

$y=mx+b\\3=\frac{1}{2}(4)+b\\3=2+b\\b=3-2\\b=1$

The equation of line will be:

$y=mx+b\\y=\frac{1}{2}x+1$

Equation of the line that passes through the given point and is (b) perpendicular is: $\mathbf{y=\frac{1}{2}x+1}$
