What is the y-intercept Of the function Represented by the table of values belowX -2 1 2 4 7 y 15 6 3 -3 -12

Kipish [7]

Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-15=\dfrac{6-15}{1-(-2)}(x-(-2))$

$y-15=\dfrac{-9}{1+2}(x+2)$

$y-15=\dfrac{-9}{3}(x+2)$

$y-15=-3(x+2)$

Adding 15 on both sides, we get

$y=-3x-6+15$

$y=-3x+9$

Putting x=0, we get

$y=-3(0)+9$

$y=0+9$

$y=9$

The y-intercept is 9. Therefore, the correct option is C.

Solve these arithmetic: 2.75+0.003+0.158 =

olganol [36]

First, let's add 2.75 + 0.158. First, we add the thousandths places. Now, we have 2.758 + 0.15. Next, let's add the hundredths place. This is equal to 2.808+0.1. Finally, we have the tenths place. Now, our number is 2.908.

To finish this problem, we add 0.003. 2.908 + 0.003 = 2.911, so 2.911 is the answer to this problem.

Marcus needs to bike at least 80 mi this week for a training if he has already bike 25 mi this week then how many miles should h

Rashid [163]

Marcus needs to bike at least 11 miles each day.

Step-by-step explanation:

Given,

Distance to cover = 80 miles at least

Distance already biked = 25 miles

Number of days left = 5

Let,

x be the distance to cover in 5 days.

According to given statement;

Number of days left * Distance to cover + distance already bike ≥ Total distance to travel

$5x+25\geq 80\\5x+25-25\geq 80-25\\5x\geq 55$

Dividing both sides by 5

$\frac{5x}{5}\geq \frac{55}{5}\\x\geq 11$

Marcus needs to bike at least 11 miles each day.
