Answer:

Step-by-step explanation:

lets replace x with 3

f(3)= -2(3)^3+3(3+2)=-2*27+15=-54+15=-39

The graph of a line passes through the points (0,-2) and (6,0). What is the equation of the line?

Dima020 [189]

Answer:

y=1/3x-2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-(-2))/(6-0)

m=(0+2)/6

m=2/6

simplify

m=1/3

y-y1=m(x-x1)

y-(-2)=1/3(x-0)

y+2=1/3(x)

y+2=1/3x

y=1/3x-2

Alan compared the slope of the function y=3x+2 to the slope of the linear function that fits the values in this table. Which cho

Anastaziya [24]

OPTIONS:

*The slope of the graph of the table is 1 more than the slope of the graph of the equation.

*The slope of the graph of the table is 2 more than the slope of the graph of the equation.

*The slope of the graph of the equation is 2 more than the slope of the graph of the table.

*The slope of the graph of the equation is 1 more than the slope of the graph of the table.

Answer:

The slope of the graph of the equation is 1 more than the slope of the graph of the table.

Step-by-step explanation:

The slope in the equation of the function, y = 3x + 2, is identified as 3.

We know this because, the equation for the function was given in the slope-intercept form, y = mx + b, where m represents the slope.

Therefore, the slope of the function is 3.

The slope of the function represented by the table of values can be calculated using any two given pairs on the table.

Using (1, 6) and (3, 10):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_2} = \frac{10 - 6}{3 - 1} = \frac{4}{2} = 2$

Slope of the function represented by the table of values is 2.

Therefore, comparing the slope of both functions, we can conclude that:

✅"The slope of the graph of the equation is 1 more than the slope of the graph of the table."

You roll a number cube. Find the probability and write your answer in the simplest form. P(4)= ---------------------------------

alina1380 [7]

Answer:

$P(4) = \frac{1}{6}$

$P(\text{not a 2}) = \frac{5}{6}$

$P(\text{3 or 5}) = \frac{1}{3}$

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Number cube:

A number cube is a dice, which has six sides, numbered 1 to 6.

P(4)

One the sides is a 4, thus:

$P(4) = \frac{1}{6}$

P(not a 2)

Of the 6 sides, one is a 2, and the other 5 are not 2. So

$P(\text{not a 2}) = \frac{5}{6}$

P(3 or 5)

One sides is 3, other is 5, 1 + 1 = 2. So

$P(\text{3 or 5}) = \frac{2}{6} = \frac{1}{3}$
