Answer:
y = -25x + 170
Step-by-step explanation:
For the graph equation y = ax + b, we have to find a and b.
Pick two points that are on the grid for best accuracy.
e.g., (2,120) and (6,20)
Then a = (20-120)/(6-2) = -25
b is the y coordinate of the line with the y axis: 170
So the formula is:
y = -25x + 170

Which of the following illustrates the Distributive Property?
A. 3(2x + 4) = 5x + 4
B. 3(2x + 4) = 5x + 7
C. 3(2x + 4) = 6x + 4
D. 3(2x + 4) = 6x + 12
Answer:
I think that the correct answer is D 3(2x + 4) = 6x + 12
3(2x + 4) = 6x + 12 illustrates the Distributive Property. Correct option is D.
The Distributive Property states that when you multiply a number by a sum or difference inside parentheses, you distribute the multiplication across each term inside the parentheses.
The correct illustration of the Distributive Property among the given options is:
D. 3(2x + 4) = 6x + 12
This is because when you distribute 3 across 2x and 4, you get 6x for the first term (3 * 2x) and 12 for the second term (3 * 4), resulting in 6x + 12.

A quantity with an initial value of 750 decays continuously at a rate
of 8.5% per hour. What is the value of the quantity after 147 minutes,
to the nearest hundredth?
Answer:
749.79
Step-by-step explanation:
147 minutes = 2 and 27/60 hours
8.5% times 2 and 27/60 = 0.20825 or 833/4000
750 - 0.20825 = 749.79175
749.79175 to the nearest hundredth = 749.79

Answer:
"?" = 3
Step-by-step explanation:
The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:
7 - 4 = 3
Therefore, the "?" = 3
Hope this helps :)
Answer:
?=3
Step-by-step explanation:
Okay so with exponents, when multiplying exponents with the same base, you add them.
In your case, we have a^? * a^4=a^7 (this is the only part you need to solve)
so ?+4=7
?=7-4=3

A 147 days
B200 days
205 days
D233 days
Answer:
Step-by-step explanation:
It's 205
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

You are controlling an unmanned aerial vehicle (UAV) for surveillance. The table shows the height y (in thousands of feet) of the UAV x minutes after you start its descent from cruising altitude.
Answer: y=-1/2x+58, decreases 500, begins, 58k
Step-by-step explanation:
I'm not too sure about my equation for the word problem but I can explain how I got it.
The equation is in y=mx+b format, so we need to find the slope. They gave us the graph for a reason. You would take each side of the table and subtract/add. For example: 58-53=-5 (y), 0+10=10 (x).
Then, just put that in rise over run (-5/10).
Simplify. Which gives you -1/2.
They already gave us the y-intercept, so just put it into the equation. y=-1/2x+58.
Keep in mind I don't know if you need to add the 0's because it's thousands of feet, I would just in case though. Hoped this helped!
The equation can be given as [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].
Given to us,
x is time in minutes
y is the height (in thousands of feet) of the UAV
x y
0 58
10 53
20 48
30 43
The equation can be given as y = mx+ c
where,
x is time in minutes,
y is the height,
m is the slope,
c is the constant,
Substituting the values of x and y to get m and c,
Equation 1:
[tex]y = mx+ c\\ 58 = m(0) + c \\ c = 58[/tex]
Substituting the values of c to get m,
Equation2:
[tex]y = mx+ c\\53 = m(10) + 58\\m\times (10) = - 58 + 53\\m\times (10) = -5\\m =- \frac{1}{2}[/tex]
[tex]y= -\frac{1}{2}x +58[/tex]
Therefore, the equation can be given as [tex]y= -\frac{1}{2}x +58[/tex], and slope for x and y is m that is [tex]\dfrac{-1}{2}[/tex].

The lcm of 120 and n is 2520. Find the smallest value of n.
Please explain the answer. Thank you.
Answer: The smallest value of n is:
n = 21
Step-by-step explanation:
We know that the LCM (least common multiple) between 120 and n is 2520.
We want to find the smallest value of n.
The smallest value of n will be such that n does not share any prime number with 120, then the greatest common factor between 120 and n is 1.
Remember that the LCM between A and B is:
LCM(A, B) = A*B/(GCM(A, B))
Then if the greatest common factor between A and B is 1, we will have:
LCM(A, B) = A*B
Then if the greatest common factor between 120 and n is 1, we have that:
LCM(120, n) = 120*n = 2520
then:
n = 2520/120 = 21
The smallest value of n is n = 21.

The monthly rent during the 8th year of living in the apartment will be $2160.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.
Then the monthly rent during the 8th year of living in the apartment will be
Let y be the monthly rent and x be the number of years.
Then we have
y = 170x + 800
The rent after 8 years, then the rent will be
y = 170 × 8 + 800
y = 1360 + 800
y = $ 2160
Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.
