Using proportions, it is found that the expression that tells how much greater the basketball score difference was on Wednesday than on Thursday is:
<h3>What is a proportion?</h3>
A proportion is a <u>fraction of total amount.</u> Then, to find how much greater an amount a is compared to an amount b, the expression is 
.
In this problem:
- The difference of scores on Wednesday is of 68 - 54 = 14.
- On Thursday, it is of 59 - 48 = 11.
Hence, the expression that tells how much greater the basketball score difference was on Wednesday than on Thursday is:

7. is (4x+9)/7=f(x) because you switch the x and y and then solve for y.
f(x)=y
y=(7x-9)/4
x=(7y-9)/4
4x=7y-9
4x+9=7y
(4x+9)/7=y
Answer:
slope-intercept form: y = x+2
The slope is 1
y-interspet is -2

Answer:
1
Step-by-step explanation:
You want to know the value of i^4.
<h3>Powers of i</h3>
The fourth power of i, √(-1), can be found the same way the value of any fourth power can be found: carry out the multiplication.
i^4 = i·i·i·i = -1·i·i = -i·i = -(-1) = 1
The fourth power of i is 1.

<em>Additional comment</em>
As you can see from the evaluation process, ...
i¹ = i
i² = -1 . . . . . definition of i
i³ = -i
i⁴ = 1
The sequence repeats for higher powers.
