When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.

Then when you look at the second one, it goes right one and up four.

As rise over run, it would be 4 / 1 or simply 4.

The slope is 4 and the y-intercept is -2

Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.

y = 4x -2

Which equation represents a line that is perpendicular to the line whose equation is -2y=3x+7

notsponge [240]

Answer:

Any line with the slope of 2/3 would be perpendicular.

Step-by-step explanation:

To find this, first solve the equation for y.

-2y = 3x + 7

y = -3/2x - 7/2

Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/2 becomes -2/3) and then we change the sign (-2/3 becomes 2/3)

Monica took a survey of her classmates' hair and eye color. The results are in the table below.

jolli1 [7]

Answer:

let R represent red hair

let G represent green eyes

from Baye's theorem:

$P( \frac{R}{G} ) = \frac{P(RnG)}{P(G)}$

P(RnG) = 5

$P(G) = { \sum}(green \: hair) \\ = (3 + 5 + 5) \\ = 13$

Therefore:

$P( \frac{R}{G} ) = \frac{5}{13} \\ = 0.385$

The conditional relative frequency = 0.385

The number of users of a cell tower in a small, developing town increased by a factor of 1.5 every year from 2010 to 2019. The f

polet [3.4K]

Answer:

Step-by-step explanation:

From the statement, we are given a function that shows the number of cell tower users f(x) after x years, from the year 2010 to 2019, so, to solve the problem, we need to remember that the domain is equal to all the values that the variable (x for this case) could take making the function itself exist.

So, the given function is a function of years, and we know that "x" represents the years from 2010 (starting value), to 2019 (ending value) meaning that the domain is located between those two values.

Hence, the correct option is:

B. 0 ≤ x ≤ 5,000
