vredina [299]

Answer:

equation of line

x-2y=8

Step-by-step explanation:

equation of line in slope intercept form

(y-y1)={(y2-y1)/(x2-x1)}(x-x1)

or,(y+3)={(-5+3)/(-2-2)}(x-2)

or,(y+3)=(1/2)(x-2)

or,2y+6=x-2

or,6+2 =x-2y

or,x-2y=8

Which scenario best matches the linear relationship expressed in the equation y = 13.50x + 300?

Fofino [41]

Answer:

Option C is correct.

Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.

Step-by-step explanation:

Slope intercept form: An equation of line is given by: $y=mx+b$ ......[1] where m is the slope and b is the y-intercept

Given the linear equation: $y = 13.50x+300$

Here, x represents the yearbook sold.

On comparing with the equation [1] we have;

m = $13.50

b =300

therefore, the best scenario best matches the linear relationship is:

Bobby has $300 in the yearbook fund and earns $13.50 for each yearbook sold.

Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d

Answer:

$x=\frac{7}{5}$

$y=-\frac{22}{5}$

Step-by-step explanation:

Given:

The given expressions are.

$6x+y=4$

$x-4y=19$

We need to find x and y values.

Solution:

Equation 1⇒ $6x+y=4$

Equation 2⇒ $x-4y=19$

First solve the equation 1 for y.

$6x+y=4$

$y = 4-6x$ --------(3)

Substitute $y = 4-6x$ in equation 2.

$x-4(4-6x)=19$

Simplify.

$x-(4\times 4 - 4\times 6x)=19$

$x-(16-24x)=19$

$x-16+24x=19$

Add 16 both side of the equation.

$25x-16+16=19+16$

$25x=35$

$x=\frac{35}{25}$

Divide Numerator and denominator by 5.

$x=\frac{7}{5}$

Substitute x value in equation 3 and simplify.

$y=4-6(\frac{7}{5})$

$y=4-\frac{6\times 7}{5}$

$y=4-\frac{42}{5}$

$y=\frac{5\times 4-42}{5}$

$y=\frac{20-42}{5}$

$y=-\frac{22}{5}$ .

Therefore, the value of $x=\frac{7}{5}$ and $y=-\frac{22}{5}$ .
