Answer:

y=-3x+14

Step-by-step explanation:

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

m=(-4-26)/(6-(-4))

m=-30/(6+4)

m=-30/10

m=-3

y-y1=m(x-x1)

y-26=-3(x-(-4))

y-26=-3(x+4)

y=-3x-12+26

y=-3x+14

NikAS [45]

Answer:

Geometric sequence

Step-by-step explanation:

Since the accidents increase by 5% this represents that the number is increasing exponentially . So the sequence is geometric sequence. The geometric sequence can be represented by: a, ar, ar^2, ar^3...

Six plus four times a number plus four times four minus four times the number no

zalisa [80]

Answer:

The resultant expression would be 22 - 12x

Step-by-step explanation:

Let x be the unknown number,

Six plus four times a number = 6 + 4x

Four times four minus four times the number number = 4(4 - 4x)

Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)

Using distributive property,

6 + 4x + 16 - 16x

Combining like terms,

22 - 12x

The scatter plot shows the amount of sunlight some tomato plants received and the amount of each plant grew

Studentka2010 [4]

Answer:

Option D

Step-by-step explanation:

The complete question is attached herewith.

Also the options for the same are as follows -

What is the meaning of the slope of the trend line shown on the scatterplot?

A A plant grows about 3 inches for every 2 hours of sunlight it receives.

B A plant grows about 2 inches for every 3 hours of sunlight it receives.

C A plant grows about 3 inches for every 1 hour of sunlight it receives.

D A plant grows about 1 inch for every 3 hours of sunlight it receives.

Solution

If we look at the graph, we can see that in 6 hours the tomato plant grew by 2 inches.

At the X axis, when x = 6 hours, the y co-ordinate at X = 6 hours is 2 inches.

Hence, It can be interpreted that 1 inch of the tomato plant grows in 3 hours.

Hence, option D is correct

Find all the values of x where the tangent line is horizontal.<br> 2x^3+36x^2+192x+12

Afina-wow [57]

At x = -4 and -8
Take the derivative of the given equation to find rate of change of the graph.
f'(x) = 6x^2 + 72x + 192
At a horizontal tangent, f'(x) = 0, so set the equation equal to 0 and solve. Eventually you get x = -4 and -8
