Mathematics
1 answer:
wolverine [178]3 years ago
3 0

Answer:

150%

Step-by-step explanation:

this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!

Find the range of the function f(x)=x2+5 given the domain (-2,-1,0,1,2)?
iren2701 [21]

Answer:

(5, 6, 9)

Step-by-step explanation:

The domain is basically the set of all x values while the range is the set of all y values, in this case, it's the values of f(x). To find the range, we can plug the x values into the equation:

f(-2) = 9

f(-1) = 6

f(0) = 5

f(1) = 6

f(2) = 9

Since we can't have repeats in the range, it would be: (5, 6, 9)

Slope and y intercept
morpeh [17]

Answer:

y=\frac{25}{1}x+75

The beginning balance of Sophie's account is 75

Step-by-step explanation:

Using the slope intercept form aka y=mx+b

The slope of a line describes how steep a line is.

  • We can see that the y-axis goes up by 25.
  • 25, 50, 75, 100, 125, 150 etc

<u>$ is how much you have in your bank account.</u>

<em>We can see that Sophie starts off with 75 dollars.</em>

In the first week, we see that Sophie has 100 dollars. In the second week, we see that Sophie has 125.

<h3>how to find the slope</h3>

slope formula\\m=\frac{rise(y)}{run(x)}=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

The first week (1, 100)

The second week (2,125)

(x_{1}, y_{1})= 1, 100\\(x_{2}, y_{2})= 2, 125\\m=\frac{125-100}{2-1}=\frac{25}{1}    \\Up 25 (aka, 1 line), over 1(aka 2 lines)
