If f(x) = 3x - 15, what is f(4)?
A. 3
B. -3
c. 12
D. -8

Answers

Answer:

B. -3

Step-by-step explanation:

f(x) = 3x - 15

f(4) means x=4, so you want to plug 4 into the equation.

f(4) = 3(4) - 15

f(4) = 12 - 15

f(4) = -3

Answer:

B

Step-by-step explanation:

f(4) has the same meaning (for this question ) as x = 4

Let x = 4

f(4) = 3*4 - 15

f(4) = 12 - 15

f(4) = - 3

Answers

Answer:

[tex]y=\frac{5+8x}{10} , x=x[/tex]

Step-by-step explanation:

y-0.8x=0.5

y*10-0.8x*10=0.5*10

10y-8x=5

10y-8x+8x=5+8x

10y/10=5/10+8x/10

y=5+8x/10

5*5+8x/10-2.5

8x+5/2-2.5=4x

y=5+8x/10, x=x

A motor travels 10 mph in still water. The boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream. Find the rate of the current.

Answers

Answer:

The rate of the current is 2 mph.

Step-by-step explanation:

When the boat travels upstream we have:

[tex] v_{T_{1}} = v_{b} - v_{c} [/tex]                      

[tex] \frac{x_{1}}{t_{1}} = v_{b} - v_{c} [/tex]    

Where:

[tex] v_{T}[/tex]: is the total speed

[tex]v_{b}[/tex]: is the speed of the boat = 10 mph

[tex]v_{c}[/tex]: is the speed of the current

x: is the distance

t: is the time

And when the boat travel downstream we have:

[tex]v_{T_{2}} = v_{b} + v_{c}[/tex]        

[tex] \frac{x_{2}}{t_{2}} = v_{b} + v_{c} [/tex]                              

Since the boat takes 4 hours longer to travel 48 miles going upstream than it does to travel 24 miles going downstream we have:

[tex] \frac{x_{1}}{t + 4} = v_{b} - v_{c} [/tex]   (1)

[tex] \frac{x_{2}}{t} = v_{b} + v_{c} [/tex]   (2)

By adding equation (1) with (2):

[tex] \frac{x_{1}}{t + 4} + \frac{x_{2}}{t} = 2v_{b} [/tex]

[tex] tx_{1} + (t+4)x_{2} - 2v_{b}t(t+4) = 0 [/tex]

[tex] 48t + 24(t+4) - 2*10t(t+4) = 0 [/tex]

By solving the above equation for t we have:

t = 2 h      

Now, by entering "t" into equation (2) we have:

[tex] \frac{24 miles}{2 h} = 10 mph + v_{c} [/tex]  

[tex] v_{c} = 2 mph [/tex]

               

Therefore, the rate of the current is 2 mph.

I hope it helps you!

Write an equation using slope intercept form when m=4 and b=12

Answers

Answer:

y = 4x + 12

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.

plug in 4 for m.

y = mx + b ⇒ y = 4x + b

plug in 12 for b.

y = 4x + b ⇒ y = 4x + 12

it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.

the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3
