Write an equation for line L in point-slope form and slope-intercept form.

Marianna [84]

Answer:

$y = -\frac{1}{4}x + c$ --- Slope intercept

$y - y_1 = -\frac{1}{4}(x - x_1)$ --- Point slope

Step-by-step explanation:

Given

Perpendicular to $y = 4x$

Required

Determine its equation

The general form of an equation is:

$y = mx + c$

Where

$m = slope$

By comparison:

$m = 4$

Next, we calculate the slope of L.

Because L is perpendicular to $y = 4x$ , the relationship between their slopes is:

$m_2 = -\frac{1}{m}$

Substitute 4 for m

$m_2 = -\frac{1}{4}$

The equation of L in slope intercept form is: $y = mx + c$

Substitute -1/4 for m

$y = -\frac{1}{4}x + c$

In point slope form, we have:

$y - y_1 = m(x - x_1)$

Substitute -1/4 for m

$y - y_1 = -\frac{1}{4}(x - x_1)$

A motorboat traveling with a current can go 120 km in 4 hours. Against the current, it takes 6 hours to go the same distance. Fi

Aleks04 [339]

Answer: Speed of motorboat= 25 km hr

Speed of current= 5km hr

Step-by-step explanation:

120/4= speed of motorboat with the current

120/6= speed of motorboat against the current

Get the average of those 2 numbers.

Motorboat=25 km hr

Speed of current= 5 km hr

Paul drove 225 miles to visit his parents. The graph below shows the distance traveled and the total time of the trip. Write and

ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

Average speed is the rate of change of total distance covered with time taken .

Average speed = $\frac{total distance }{time}$

To find the total distance covered;

Distance at time 1 = 75miles

Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

Average speed = $\frac{150}{3}$ = 50mph

(9·20+60)÷4−16+4·(20·5)

neonofarm [45]

$\text {Hello! Let's Solve this Problem!}$

$\text {The First Step is to Solve the Parentheses:}$

$\text {90*20=180+60=240}\\\text {20*5=100}$

$\text {Your new Problem should be: 240/4-16+4+100}$

$\text {The Next Step is to Divide:}$

$\text {240/4=60}$

$\text {Your new Problem should be: 60-16+4*100}$

$\text {The Next Step is to Subtract:}$

$\text {60-16=44}$

$\text {Now the Next Step is to Multiply:}$

$\text {4*100=400}$

$\text {The Final Step is to Add:}$

$\text {44+100=}$

$\text {Your Answer should be:}$

$\fbox {444}$

$\text {Best of Luck!}$
