Please help me because I don't understand how to do it.:)

Tanya [424]

Answer:

y = 1/4x+1

Step-by-step explanation:

We have 2 points so we can find the slope

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

= (1-2)/(0-4)

= -1/-4

= 1/4

The point (0,1) is the y intercept

We find the y intercept when x=0

We want to find the equation in slope intercept form

y= mx+b where m is the slope and b is the y intercept

y = 1/4x+1

A robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time. How long does it take the robot to complete

Vsevolod [243]

Answer:

Robot will take $\frac{3}{80}$ hour to complete each task.

The robot can complete $26\frac{2}{3}$ tasks in one hour.

Step-by-step explanation:

We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.

To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:

$\text{Time taken by robot to complete each task}=\frac{3}{10}\div 8$

$\text{Time taken by robot to complete each task}=\frac{3}{10}\div \frac{8}{1}$

Now we will convert division problem into multiplication problem by flipping the 2nd fraction.

$\text{Time taken by robot to complete each task}=\frac{3}{10}\times \frac{1}{8}$

$\text{Time taken by robot to complete each task}=\frac{3}{80}$

Therefore, robot will take $\frac{3}{80}$ hour to complete each task.

To find tasks completed by robot in one hour we will use proportions.

$\frac{x}{1\text{ hour}}=\frac{8}{\frac{3}{10}}$

$\frac{x}{1}=\frac{80}{3}$

$x=\frac{80}{3}$

$x=26\frac{2}{3}$

Therefore, the robot can complete $26\frac{2}{3}$ tasks in one hour.

What is the value of x in the circle on the right

german

To solve this we need to use Pythagorean theorem

${x}^{2} + {14}^{2} = (9 + x) ^{2} \\ {x}^{2} + 196 = 81 + 18x + {x}^{2} \\ 18x = 115 \\ x = 6.3(8) \simeq6.4$

Answer: x≈6.4
