Answer:

The equation of the line in point slope form is equal to

(y-4)=\frac{4}{3}(x+2)

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a line in point-slope form is equal to

y-y1=m(x-x1)

we have

3y-12=4x+8

Convert to point slope form

Factor 3 left side and factor 4 right side

3(y-4)=4(x+2)

Divide by 3 both sides

(y-4)=\frac{4}{3}(x+2)

In this equation

the point is (-2,4)

the slope is m=\frac{4}{3}

using a graphing tool

The graph in the attached figure

Find the average rate of change of the function between the given values of x. y = 9+ 5x + 0.5x2 between x = 2 and x = 4.
svet-max [94.6K]

Answer:

The average rate of change is 8.

Step-by-step explanation:

The formula to calculate the average rate of change of a function F(x) is:

\frac{F(b)-F(a)}{b-a}

In this case, F(x) = 0.5x^{2} +5x+9

a=2 and b=4

You have to evaluate x=2 (which is a in the formula) and x=4 (which is b in the formula) in the function.

In order to obtain F(b) and F(a) you have to replace x=4 and x=2 in the given function:

F(b) = (0.5)4^{2} + 5(4) +9= 37

F(a) = (0.5)2^{2} + 5(2)+9=21

\frac{F(b)-F(a)}{b-a} = \frac{37-21}{4-2}=\frac{16}{2} = 8

The answer is 8.

Plz help asap !! The high school jazz band is selling homemade leather bracelets at a local craft fair to raise money for a trip
torisob [31]

Answer:

y = 2x - 200

Step-by-step explanation:

The function type that would model this relationship is linear because for each bracelet sold, the jazz band would increase their profit by $2.  Since it has a consistent rate, it is linear.  Using the slope-intercept formula of y = mx + b, where 'm' is the rate and 'b' is the initial value, you can use $2 for the rate or cost per bracelet and -$200 for the initial value or cost of supplies:

y = 2x - 200, where '2' is the cost per bracelet, 'x' the number of bracelets sold, '-200' is the cost for supplies and 'y' is the profit.
