Answer:
x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.
Step-by-step explanation:
Let Lin works x hours per week.
Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.
And she has to work at least 5 hours a week to $175 per week.
So, the inequality that can be written from the above condition is x ≥ 5 .......(1)
And the equation that can be written that
8.25x + 10 = 175 ....... (2)
So now we can write x = 20 hours

The particular solution to the differential equation which describes the number of fish over time will be y = 40(0.99)^t.
<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 %
A population of endangered salmon, S(t), starts out with 40 fish and decreases proportionally at a rate of 0.01 fish per year. Let t be measured in years.
Let y be the number of fish over time (t).
Then we have

Then the particular solution to the differential equation which describes the number of fish over time will be y = 40(0.99)^t.

Answer:
3x²(4x-3)
Step by step explanation:
Factorise 12x³-9x²
first, find the HCF of the terms.
the HCF is 3x²
Then you can use the HCF to multiply all terms, each divided by the HCF.
3x²(12x³/3x²-9x²/3x²)
Dividing, we'll have
3x²(4x-3)
Answer:
It would be 40
Step-by-step explanation:
Answer:
y= -3/2x + 5
Step-by-step explanation:
You do the opposite reciprocal of the original equation's slope.
Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).
That gets your answer of -3/2x + 5.
