An electric utility company determines the monthly bill for a residential customer by adding an energy charge of 7.32 cents per

Sedaia [141]

Answer:

$y(x) = 0.0732x + 17.32$

Step-by-step explanation:

The equation for the monthly charge has the following format

$y(x) = ax + b$

In which y(x) is the cost in function of the number of kilowatt-hours used(x), a is the price of each killowatt hour and b is the fixed(base) charge.

Base charge of $17.32 per month.

This means that $b = 17.32$

charge of 7.32 cents per kilowatt-hour

Our answer is in dollars. Each dollar is 100 cents. So 7.32 cents is $a = 0.0732$

Write an equation for the monthly charge y in terms of x, the number of kilowatt-hours used.

$y(x) = ax + b$

$y(x) = 0.0732x + 17.32$

What equation is parallel to the line 3x+y=5

Alex_Xolod [135]

Answer:

Any equation with the slope -3 and a y intercept that does not equal 5

Step-by-step explanation:

a line is parallel if the line have the same slope, and different y intercepts

3x+y=5

in slope intercept form is

y=-3x+5

slope : -3

y intercept 5

pllllllls I need help right triangle and trigonometry special right triangles find the value of each variable

yanalaym [24]

$\huge {\mathfrak{Answer : }}$

we know,

$\boxed{\cos( \theta) = \dfrac{base}{hypotenuse}}$

so,

$\cos(30) = \dfrac{24}{x}$

$\dfrac{ \sqrt{3} }{2} = \dfrac{24}{x}$

$x = \dfrac{24 \times 2}{ \sqrt{3} }$

$x = 8 \sqrt{3} \times 2$

$x = 16 \sqrt{3}$

now,

$\boxed{ \tan( \theta) = \frac{perpendcular}{base} }$

$\tan(30) = \dfrac{y}{24}$

$\dfrac{1}{ \sqrt{3} } = \dfrac{y}{24}$

$y = \dfrac{24}{ \sqrt{3} }$

$y = 8 \sqrt{3}$

Linear equation are the equation which has the highest power of the unknown variable is 1.The expressions given in the option 1, 2, and 3 are equivalent to $7x - 14$ .

The equations given in the problem are the linear equations.

<h3>Linear equation</h3>

Linear equation are the equation which has the highest power of the unknown variable is 1.

Given-

1) The given expression in the problem is,

$f(x)=7x-14$

Rewrite the equation as,

$f(x)=(7x-14)$

Take out the negative sign from the bracket,

$f(x)=-(-7x+14)$

Rewrite the equation with positive terms first.

$f(x)=-(14-7x)$

Hence the given equation is equivalent to the option 1.

2) The given equation,

$f(x)=7x-14$

On solving further take out the 7 common from the bracket,

$f(x)=7(x-2)$

Thus the given equation is equivalent to the option 2.

3) The given equation,

$f(x)=7x-14$

Split the term of <em>x,</em>

Rewrite the equation,

$f(x)=3x-14+4x$

Hence the given equation is equivalent to the option 3.

4) The given equation,

$f(x)=7x-14$

Split the term of <em>x </em>and constant term,

Rewrite the equation,

$f(x)=2x-10+5x-4$

Hence the given equation is not equivalent to the option 4.

Thus the expressions given in the option 1, 2, and 3 are equivalent to $7x - 14$ .
