Please answer the correct answer I will give brainliest. Use the graph to write a linear function that relates y to x. y=
Mumz [18]

Answer:

y = 3

Step-by-step explanation:

We need to find the slope. We do so by choosing any two points and dividing the change in the y-coordinates (their difference) by the change in the x-coordinates (their difference). Let's just choose (1, 3) and (0, 3). The slope is:  . So, the slope is 0.

We want to write a line in slope-intercept form, which is: y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y-axis). Here, the slope m = 0. Looking at the graph, we see that the y-intercept is (0, 3), so b = 3. Then, our line is: y = 0x + 3  ⇒  y = 3.

Another note is that this is a horizontal line. One thing to remember is that all horizontal lines have slopes of 0, so their function is simply y = k, where k is a constant through which the line cuts through.

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?
Alex Ar [27]

Answer:X+9=11

9-9|11-9

X=2

Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.

Factor x2 + 16 completely.
Dmitry_Shevchenko [17]
<h3>Answer:</h3>

Prime

<h3>Solution:</h3>
  • Let's factor this expression.
  • x^2+16
  • The expression is prime.
  • Let's see why all the other options are wrong.
  • Option A) (x+4)(x+4)
  • x*x
  • x*4
  • 4*x
  • 4*4
  • This makes x^2+8x+16, not x^2+16.

Hope it helps.
