Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20
The exponential function will be the amount of the saving account after $75 is invested at a rate of 11% for x number of years. Then the correct option is D.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 ± r) ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The first options are examples of the linear system.
The amount of the saving account after $75 is invested at a rate of 11% for x number of years is modeled as,
Amount = 75 (1 + 0.11)ˣ
Then the correct option is D.

The three angles must add up to 180 degrees.
x - 39 + x - 29 + x = 180 Collect like terms on the left
3x - 68 = 180 Add 68 to both sides.
3x = 180 + 68
3x = 248
x = 248 / 3
x = 82.66667
Answer
x = 82,666667 for the largest angle
x - 29 = 53.666667 for the medium size angle
x - 39 = 43.666667 for the smallest size angle
