Answer:
Some possible expressions, since there's no answer choices provided:
-3(x + 3)
3(-x - 3)
Step-by-step explanation:
Expression 1:
This uses a GCF of -3, since -3x and -9 are divisible by this. Let's divide -3x and -9 by this first:
-3x / -3 = x
-9 / -3 = 3
So now, we can add these terms and multiply them by -3 to get our answer:
-3(x + 3)
And just to check, we can expand it:
-3x + -3(3) = -3x - 9
Expression 2:
This uses a GCF of 3, like the last one but it's negative. -3x and -9 are also divisible by this. Let's divide both terms by this GCF first:
-3x / 3 = -x
-9 / 3 = -3
Now, we can add these terms and multiply them by -3 to get our final answer:
3(-x - 3)
To check, once again:
-3x + 3(-3) = -3x - 9

Answer:
Divide both sides by L
Step-by-step explanation:
Because L is multiplied by W, to find W you would need to move the L to the other side by doing the reverse operation, which in this case is division.
The half life of a chemical element substance is 16 days, How long will it takes for the substance to decay from 120mg to 2 mg
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.
A triangle has two sides measuring 8 and 15. The included angle is 33°. What is the length of the side opposite the 33° angle?
Answer:
Measure of the side opposite to the angle measuring 33° is 9.37 unit
Step-by-step explanation:
If a, b and c are the sides of a triangle,
And 'a' = 8
b = 15
Measure of the Included angle C = 33°
By applying cosine rule in the given triangle,
c² = a² + b² - 2abcos(C)
c² = 8² + (15)² - 2(8)(15)cos(33°)
= 64 + 225 - 201.28
= 87.72
c = √87.72
c = 9.266
≈ 9.27
Therefore, measure of the side opposite to the angle measuring 33° is 9.37 units

First, we determine the cost function for all the three rides.
Ride A
From the graph, we have the following points
[tex](x_1,y_1) = (0,8)[/tex]
[tex](x_2,y_2) = (2,12)[/tex]
Calculate slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-8}{2-0}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex] --- This represents the rate per ride
The equation is the calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 2(x - 0) + 8[/tex]
[tex]y = 2(x) + 8[/tex]
[tex]y = 2x + 8[/tex]
So, the cost function is:
[tex]C(x) =2x + 8[/tex]
Calculate the cost of admission i.e. x=0
[tex]C(0) = 2*0+8 = 8[/tex]
So, we have:
[tex]C(0) = 8[/tex] --- Admission Charge
[tex]C(x) =2x + 8[/tex] --- Cost function
[tex]m =2[/tex] --- Rate per ride
Ride B
From the table, we have the following points
[tex](x_1,y_1) = (0,12)[/tex]
[tex](x_2,y_2) = (4,15)[/tex]
Calculate slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{15-12}{4-0}[/tex]
[tex]m = \frac{3}{4}[/tex]
[tex]m = 0.75[/tex] --- This represents the rate per ride
The equation is the calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 0.75(x - 0) + 12[/tex]
[tex]y = 0.75(x) + 12[/tex]
[tex]y = 0.75x + 12[/tex]
So, the cost function is:
[tex]C(x) = 0.75x + 12[/tex]
Calculate the cost of admission i.e. x=0
[tex]C(0) = 0.75*0 + 12=12[/tex]
So, we have:
[tex]C(0) =12[/tex] --- Admission Charge
[tex]C(x) = 0.75x + 12[/tex] --- Cost function
[tex]m = 0.75[/tex] --- Rate per ride
Ride C
No additional fee;
So, the cost function is;
[tex]C(x) = 30[/tex]
In summary, we have:
Ride A
[tex]C(x) =2x + 8[/tex] --- Cost function
[tex]m =2[/tex] --- Rate per ride
Ride B
[tex]C(x) = 0.75x + 12[/tex] --- Cost function
[tex]m = 0.75[/tex] --- Rate per ride
Ride C
[tex]C(x) = 30[/tex] --- Cost function
By comparison
Ride A has the highest rate per ride of (#2), followed by ride B with a rate of #0.75 per ride.
Ride C has no charges per ride
The impact on the total cost is that:
Ride A: People that opt for ride A will pay the least to get admitted (i.e #8) but they pay the most (i.e. #2) per each ride they take
Ride B: People that opt for ride B will pay #12 to get admitted, but they pay 0.75 per each ride they take
For A and B, the overall cost depends on the number of rides taken.
Ride C: Irrespective of the number of rides taken, people that opt for ride C will pay the same flat fee of #30

in the figure below, all lines intersect at point M. what is the measure of
Answer:
m∠GML= 65°
Step-by-step explanation:
m∠GML= 180°-(m∠GMH+m∠HMI)
= 180°-(85°+30°)

If all lines intersect at point M then the measure of GML is 65 degrees
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
We know that the vertical angles are equal
And the sum of angles on a line are 180 degrees
So 85+30+x=180
115+x=180
Subtract 115 from both sides
x=180-115
=65 degrees
Hence, if all lines intersect at point M then the measure of GML is 65 degrees

Answer:
80
Step-by-step explanation:
Look at the figure below. The perimeter is the same as if the corners were moved out to form a square. Then you have 4 congruent sides of length 20.
P = 4 * 20 = 80
The perimeter of a shape is the summation of the sides of the shape. The perimeter of the shape is 80 units.
From the attached figure, we have the following observations
All sides of the shape are either vertical or horizontal lineNone of the side lengths overlapsThis means that if the shape is drawn (see attachment) to have 4 sides, opposite sides of the shape will be congruent.
The first side length is:
[tex]Length = 20[/tex]
While the adjacent side length is:
[tex]Width = 12 + 8 =20[/tex]
The perimeter (P) of the shape is then calculated as follows:
[tex]P = 2 \times (Length + Width)[/tex]
[tex]P = 2 \times (20 + 20)[/tex]
[tex]P = 2 \times 40[/tex]
[tex]P = 80[/tex]
Hence, the perimeter of the shape is 80 units.
