At what point will 3y=4x-6 and 8x-6y=-30 intercept

Mathematics
1 answer:
tester [92]3 years ago
3 0

Answer:

The lines don't intercept

Step-by-step explanation:

we have

3y=4x-6

isolate the variable y

Divide by 3 both sides

y=\frac{4}{3}x-\frac{6}{3}

simplify

y=\frac{4}{3}x-2 -----> equation A

8x-6y=-30

Isolate the variable y

6y=8x+30

Divide by 6 both sides

y=\frac{8}{6}x-\frac{30}{6}

simplify

y=\frac{4}{3}x-5 -----> equation B

Compare equation A and equation B

The slopes are the same and the y-intercepts are different

Remember that

If two lines has the same slope, then the lines are parallel

therefore

In this problem line A and line B are parallel lines

The system of equations has no solution, because the lines don't intercept

Answer:

Quadratic Equation:

3x^2=2x +5

\text{Standard Form: } 3x^2-2x-5=0

From the standard form of a Quadratic Function, we get:

a=3,\:b=-2,\:c=-5

Discriminant:

\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)

\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5

\Delta=64

From the discriminant, we conclude that the equation will have two real solutions.

State that:

b^2-4ac

b^2-4ac =0:\text{The equation has 1 real solution}

b^2-4ac >0:\text{The equation has 2 real solutions}

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}  $

$x_{2}=\frac{-6}{6} =-1$

Different hotels in a certain area are randomly selected, and their ratings and prices were obtained online. Using technology, w
mash [69]

Answer:

Option C) The symbol y represents the predicted value of price.

Step-by-step explanation:

We are given the following in the question:

We find a regression equation with x representing the ratings and y representing price.

The equation has a slope of 130 and a y-intercept of 350.

Comparing with the slope intercept form:

y = mx + c\\\text{where m is the slope and c is the y intercept}

Thus, we can write the equation as:

y = 130x + 350

Here, y is the predicted variable that is the price, c is the price of hotel when a rating of 0 is given.

Thus, symbol y represents:

C) The symbol y represents the predicted value of price.
