3 0

Answer: User got this. x=50+6/7 is the Answer.

Step-by-step explanation:

Step 1) Move all terms to the left:

(x+4)7/3-(128)=0

2) Multiply all the terms by the denominator

(x+4)7-128*3=0

3) Add all the numbers together, and all the variables

(x+4)7-384=0

4) Multiply parentheses

7x+28-384=0

5) Add all the numbers together, and all the variables

7x-356=0

6) Move all terms containing x to the left, all other terms to the right

7x=356

x=356/7

x=50+6/7

Tom [10]

We are given that

Max's grade on the first math exam was a 94

so, first exam grade =94

His grade on his seond math exam was an 89

so, second exam grade =89

change in grade=(first exam grade)-(second exam grade)

change in grade=94-89

change in grade=5

Percentage = ( change in grade)/( first exam grade) *100

so, percentage is

=\frac{5}{94}\times 100

so,

the percent of change in Max's grade to the nearest whole percentage was 5%..........Answer

The following function represents the value of a house, in dollars, after x years: f(x) = 242,000(1.04)x What does 1.04 represen
zmey [24]
The number 1.04 represents the rate at which the house appreciates, or increases in its price annually.

As according to the values of an exponential equation, which is represented by this: y=ab^x, the a value represents the original price, the b value represents the rate of growth/decay (if growth, you add 1 to the rate, if decay, you subtract the rate from 1), and x represents the amount of times it decays or grows.

As according to the function <span> f(x) = 242,000(1.04)^x, 242,000 is the original price and 1.04 is the rate of growth since 1 has been added to the the 4% annual growth.</span>
