(-2,4),, the x axis is on the negative side so you just count how many sides back it is. I might be wrong about the number check before you write it down. And 4 is the y axis :)

Y=2x+4
Slope is 2 and the y-intercept is 4

As a salesperson at Roaring Waves Beach Supplies, Carissa receives a monthly base pay plus commission on all that she sells. If

Pani-rosa [81]

Base pay + (rate * sales) = total pay

b + r(400) = 388
b + r(700) = 454

b = 388 - 400r
now sub into 2nd equation
388 - 400r + 700r = 454
-400r + 700r = 454 - 388
300r = 66
r = 66/300
r = 0.22...22% is the rate

substitute for r
b + 400r = 388
b + 400(0.22) = 388
b + 88 = 388
b = 388 - 88
b = 300

so ur equation is : y = 0.22x + 300
y = 0.22(2600) + 300
y = 572 + 300
y = 872......so her salary when selling $2600 worth of stuff is $872

I need help on question 2 i need the simplified answer and the restrictions

Anastaziya [24]

Answer:

x cannot be 5 or -3.

$\frac{x+5}{x+3}$

Step-by-step explanation:

The restrictions for a fraction is that the bottom cannot be 0.

So if we find when the bottom is 0 we have found the values that x cannot be.

Let's solve x^2-2x-15=0.

Since the coefficient of x^2 is 1 all we have to do is find two numbers whose product is -15 and whose sum is -2.

Those numbers are -5 and 3 since (-5)(3)=-15 and (-5)+(3)=-2.

So the factored form of the equation is:

(x-5)(x+3)=0

This means either x-5=0 or x+3=0.

We do have to solve both.

x-5=0 can be solved by adding 5 on both sides.

x-5+5=0+5

x+0=0+5

x=5

x+3=0 can be solved by subtracting 3 on both sides.

x+3-3=0-3

x+0=0-3

x=-3

So x can be any number except x=5 or x=-3.

We already factored the bottom as (x-5)(x+3).

The top is a difference of squares, x^2-a^2,

which can be factored as (x-a)(x+a).

So the top factors as (x-5)(x+5).

The fraction can then be written as:

$\frac{x^2-25}{x^2-2x-15}=\frac{(x-5)(x+5)}{(x-5)(x+3)}$

This can further simplified assuming x is not 5 we can write it as $\frac{x+5}{x+3}$ . I canceled the common factor of (x-5).

Need help lol

GaryK [48]

We need to read the graph to see which are the two quantities related and how these are related.

The two quantities on the graph are:

Distance from Elena's house
Time.

Such that the distance from Elena's house is a function of the time.

<h3>How to read the graph?</h3>

We need to only read graph A, notice that she is coming back from school and going home, the graph starts at a high value and ends at zero. So we can assume that the vertical zero represents her home.

We know two events, first, she goes home and needs to come back to search for something, this is represented with the first "inverted peak" of graph A, then we have a constant line, that represents the time she is in the school looking something in her locker.

Then she goes home again, this time she finds a friend and goes to the library (this is why the line goes up again) and then she stops at the library for some time (this is why the line is horizontal for some time). Finally, she goes home, represented by the last segment of the line that intercepts the horizontal axis.

Then the two things represented in the graph are:

Distance from Elena's house (in the vertical axis) and time (in the horizontal axis).

This means that the distance from Elena's house is a function of time.

(The quantity in the vertical axis is a function of the quantity in the horizontal axis).
