You need to pay attention to see if the sides will be equal to each other or equal to 180

first picture on top left is x = -4

second picture on top right is x = 19/2

third picture on bottom left is x = -5

fourth picture on bottom right is x = 166/41

I don't under stand what is wrong.

MAXImum [283]

Answer:

In the first step, there is an issue when distributing the -3 to the terms inside of the parentheses. When multiplying the -3 to the -5, you would get an answer of +15, not -15.

The full correct process is:

(4m + 9) - 3(2m - 5) = 4m + 9 - 6m + 15

= 4m - 6m + 9 + 15

= -2m + 24

Graph the line that has a slope of 6 and includes the point (0,4).

faust18 [17]

Answer:

The equation of the line with slope 6 and containing the point (0, 4) will be:

$y = 6x+4$

The graph of the line y = 6x+4 is attached below.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

Given

The slope m = 6

The point (0, 4)

The y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

The point (0, 4) indicates that:

at x = 0, y = 4

Thus, the y-intercept b = 4

now substituting b = 4 and m = 6 in the slope-intercept form of the line equation

$y = mx+b$

$y = 6x+4$

Thus, the equation of the line with slope 6 and containing the point (0, 4) will be:

$y = 6x+4$

The graph of the line y = 6x+4 is attached below.

In a New York coupon experiment, the experiment was conducted to test the effects of the face value of coupons on the likelihood

steposvetlana [31]

Answer:

The correct approach will be "the likelihood of cashing the coupon".

Step-by-step explanation:

That what's being examined as well as calculated throughout the experiment or observational study seems to be the dependent variable (almost always widely recognized as that of the responding variable). As a consequence of the modifications to something like the independent variable, that's what modifications.
Whether large you are really at various ages would be an illustration of some kind of dependent variable.
