Which inequality has a dashed boundary line when graphed? A y>=3/5x+1 B y>= -1/3x+1 C y>3x+1
Ket [755]

Answer: C y>3x+1

Step-by-step explanation:

  • When we graph an  inequality with strictly greater of less than sign ('<' or '>'), then the graph has a dashed boundary line .
  • Further it indicates that it does not include the points on the line.

From all the given options , only C contains inequality with '>' sign .

Hence, y>3x+1 is the inequality has a dashed boundary line when graphed.

hence, the correct option is C.

Consider this system of equations:
alexandr1967 [171]
<span>"For which value of k does the system have no real number solutions?"
The answer is 4, because 4+4</span>≠16.
<span>
"For which value of k does the system have one real number solution?"
</span>The answer is -0.25, because the linear line because tangent with the parent function.


<span>"For which value of k does the system have two real number solutions?"
</span>The answer is 2, because the linear function intercepts the parent function 2 times.

a line of best fit for the data is y=0.9x-4.5, where x represents age in year, and in years, and y represents hourly pay, in dol
Wittaler [7]

Answer:

$18

Step-by-step explanation:

Given:

y = 0.9x - 4.5

Where,

x = age in years

y = hourly pay in dollars

what is the best prediction for the hourly pay of a 25 year old?

That is, find y when x=25

y = 0.9x - 4.5

= 0.9(25) - 4.5

= 22.5 - 4.5

= 18

y = $18

The prediction for the hourly pay of a 25 year old is $18

5. Sara has a photo that is 5 inches by 7 inches. When she adds a frame
stiv31 [10]

Answer:

  1 inch

Step-by-step explanation:

Factors of 63 are 7 and 9, each of which is 2 more than the dimensions of the photo. Sarah's frame is 1 inch wide.

_____

A 1-inch wide frame adds 2 inches to length and width.

_____

<em>Solution using an equation</em>

If you let w represent the width of the frame, the area of the framed photo is ...

  (5+2w)(7+2w) = 63

  4w^2 +24w -28 = 0 . . . . write in standard form

  w^2 +6w -7 = 0 . . . . . . . . divide by 4

  (w -1)(w +7) = 0 . . . . . . . . factor

The positive solution to this equation is w=1.

The width of the frame is 1 inch.
