Answer:

<h3>Explain wether the graph represents a function.</h3>

<em>The graph represents a function because each x-value corresponds to exactly one y-value.</em>

For example, in the given graph you see that for x=2 there's only one corresponding value, which is, y=40, that's what defines a function. If you have a graph where a certain value of x has to y values, that means is not a function, because for one x-value would be more than one y-values, so that would be only a relation, not a function.

It's important to specify the right order, that is, if we say each y-value corresponds to exactly one x-value, that's not exactly de definition of a function, because it actually happens, because in a quadratic expression, 2 and -2 would be the same result 4, so one y-vale has two x-value, but it's still a function.

So, the right order is <em>The graph </em><em>represents</em><em> a function because each </em><em>x-value </em><em>corresponds to </em><em>exactly</em><em> one </em><em>y-value.</em>

14 less than 8 times a number is 3 more than 4 times the number. What is the number? ​
e-lub [12.9K]

Answer:

x = 17/4

Step-by-step explanation:

Let x = the number

8x-14 = 4x+3

Subtract 4x from each side

8x -14-4x = 4x+3-4x

4x-14 = 3

Add 14 to each side

4x-14+14 = 3+14

4x = 17

Divide by 4

4x/4 = 17/4

x = 17/4

Help what do I do do i just write y-3x+5 or solve it ​
Rina8888 [55]

Answer:

y=-3x+5

Step-by-step explanation: Yes you have it correct. The question is asking for you to put it into an equation that fits the slope and y-intercept which is slope-intercept form. Additional note, when you have a problem like this and it doesn't say what type of equation form to put it in, put it in slope-intercept form for simplicity's sake.

A line passes through (−1, 7) and (2, 10).
Murljashka [212]
The formula is y=mx+b
To get the slope or m, use this formula
(the second y minus the first y)/(the second x minus the first x)
Now set it up.
(10-7)/(2--1)
3/3=slope is 1.
y=1x+b

Insert one of the points for x and y.
i will do (-1,7)
7=1(-1)+b
7=-1+b
8=b
Insert this into the final equation:
y=1x+8

Try it out. If you're not sure, try both points. If it works, then you set it up correctly.
