Graph is incorrect.

Find points (x,y)

If x=#, what does y=?

Example:

Y=5x+4

Y=5•0+4

Y=0+4

Y=4

Points:

(0,4)

(-1,1)

(-2,-6)

Also, only draw the line in areas where x≤0

Meaning nothing should be on the right half of the square.

The range means what Y values are possible?

When draw properly, with nothing on the right half, the highest Y value will be 4.

So, the range is y≤4

Answer:

The range is  f(x) <= 4.

Step-by-step explanation:

The general form of a straight line is y = mx + c where m = the slope of the line and c = the y-intercept. If we compare this with y = 5x + 4 we see that the slope = 5 and the y-intercept is 4.

Your graph has got the wrong slope . The slope should be the coefficient of x which is 5. The slope of your graph ( rise / run) = 1. The y-intercept is +4 which you have correct.

Also since the domain is x <= 0 the line should stop

at the point (0, 4)  because the maximum value of y  is 4.

The price of a technology stock has dropped to $9.71 today. Yesterday's price was $9.80. Find the percentage decrease.
Vadim26 [7]

Answer:

The percentage decrease = 0.9%

Step-by-step explanation:

  • Initial value = $9.80
  • Final value = $9.71

Using the formula

Percentage Decrease = [ (Initial Value - Final Value) / |Initial Value| ] × 100

                                    = [(9.80 - 9.71 ) / (9.80)] × 100

                                    = [0.09 / 9.80] × 100

                                    = 0.009 × 100  

                                    = 0.9%

Therefore, the percentage decrease = 0.9%

HELP- PLS SOMEONE HELP ME SOB
BlackZzzverrR [31]

Answer:

150 degrees

Step-by-step explanation:

Use the equation below to find the sum of all the interior angles in this polygon:

(number of sides - 2)*180

number of sides = 6

(6-2)*(180) = 4*(180) = 720

Now that you know the total sum, subtract all other angles to find x:

720 - 90 - 162 - 101 - 96 - 121 = 150
