Question:

Give all the x and y intercept of the function

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30}

Answer:

The x intercepts are x = 5 and x = -4

The y intercept is at y = -2

Step-by-step explanation:

Factorizing the numerator of the expression we find the x intercepts as follows;

f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30} =\frac{3(x-5)(x+4)}{2x^3 + 2x^2-34x+30}

Therefore, the x intercept are

x = 5 and x = -4

To find the y intercept, we put x = 0 to get y = -2

Therefore, the y intercept is at y = -2

Factorizing the denominator we find the values for which the equation is undefined

2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives

x = 1, 3 and -5.

A used car dealer sells SUVs and cars. Of all the vehicles, 85% are cars. Of all the vehicles, 32% are red cars. What is the pro
oksian1 [2.3K]

Answer:

37.6%

Step-by-step explanation:

P(A|B) = P(A and B) / P(B)

P(red | car) = P(red and car) / P(car)

P(red | car) = 0.32 / 0.85

P(red | car) = 0.376

For each pair of points below, think about the line that joins them. For which pairs is the line parallel to the y-axis? Circle
zaharov [31]

Answer:

a) Not parallel to y-axis

b) Not parallel to y-axis

c) Parallel to y-axis

Step-by-step explanation:

The best way to check whether a line passing through two points is parlle to y-axis is by plotting them on graph.

The equation of line: (y-y_1) = \frac{y_2 - y_1}{x_2 - x_1}(x-x_1)

a) The line joining the points (4,12) and ( 6,12) is not parallel to y-axis.

It is parallel to x-axis.  Another two points that can lie on this line are : (5,12) and (\frac{9}{2},12).

b) The line joining the points (\frac{3}{5}, \frac{13}{5}), (\frac{1}{5} ,\frac{8}{5}) is not parallel to y-axis.

Equation of line: 5y - 7.5x = 5.5

Another points that could be lie on this line are (0.6,2) and (0.25,1.475)

c) The line joining the points (0.8, 1.9), (0.8,2.3) is parallel to y-axis because points have the same x-coordinate.

Another points that could be lie on this line are (0.8,2) and (0.8,2.1)
