f(a) = 2a - 1
g(a) = 4a
- 1
Find f(a) + g(a)
Answer:
[tex]f(a)+g(a)=6a-2[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(a)=2a-1\text{ and } g(a)=4a-1[/tex]
And we want to find f(a) + g(a).
So, substitute:
[tex]f(a)+g(a)[/tex]
This is the same as:
[tex]=(2a-1)+(4a-1)[/tex]
Combine like terms:
[tex]=(2a+4a)+(-1-1)[/tex]
Add or subtract:
[tex]=6a-2[/tex]

Find the equation of the line with slope -2 which goes through the point (-6,-9).
The equation of the line with slope -2 which goes through the point (-6,-9) is y=-2x-21.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, the line with slope -2 which goes through the point (-6,-9).
Substitute m=-2 and (x, y)=(-6,-9) in y=mx+c, we get
-9=-2×(-6)+c
-9=12+c
c=-21
Substitute m=-2 and c=-21 in y=mx+c, we get
y=-2x-21
Therefore, the equation of the line with slope -2 which goes through the point (-6,-9) is y=-2x-21.

Find the coordinates of the point 3/10 of the way from A to B.
Answer:
[tex] (\frac{3}{13}, -3) [/tex]
Step-by-step explanation:
Apply the formula following formula to find the coordinate pair of the point that is 3/10 of the way from A(-3, -6) to B(11, 7):
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] A(-3, -6) = (x_1, y_1) [/tex]
[tex] B(11, 7) = (x_2, y_2) [/tex]
[tex] m = 3, n = 10 [/tex]
Finding the x coordinate:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{3(11) + 10(-3)}{3 + 10} [/tex]
[tex] x = \frac{33 - 30}{13} [/tex]
[tex] x = \frac{3}{13} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{3(7) + 10(-6)}{3 + 10} [/tex]
[tex] y = \frac{21 - 60}{13} [/tex]
[tex] y = \frac{-39}{13} [/tex]
[tex] y = -3 [/tex]
The coordinates of the point 3/10 of the way from A to B are [tex] (\frac{3}{13}, -3) [/tex]

At the beginning of a study of individuals, 10% were classified as heavy smokers, 20% were classified as light smokers, and 70% were classified as nonsmokers. In the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively. A randomly selected participant died over the five-year period: calculate the probability that the participant was a nonsmoker.
Answer: 0.39
Step-by-step explanation:
Given the following classification :
Heavy smokers (H) = 10%
Light smokers (L) = 20%
Non smokers (N) = 70%
Given that :
The death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively
Let probability of death = D
P(D | N) = d
P(D | H) = 5d
P(D | L) = 3d
Hence,
P(D) = [P(H) * P(D | H) + P(L) * P(D | L) + P(N) * P(D | N)]
P(D) = [0.1 * 5d + 0.2 * 3d + 0.7 * d]
P(D) = [0.5d + 0.6d + 0.7d]
P(D) = 1.8d
A randomly selected participant died over the five-year period: calculate the probability that the participant was a nonsmoker.
P(N | D) = [P(N) * P(D | N)] / P(D)
P(N | D) = 0.7d / 1.8d
P(N | D) = 0.3888
= 0.39
What is formed when polyatomic ions bond with other ions? ionic compounds neutral compounds ionic elements neutral elements
Answer:
iconic compounds
Step-by-step explanation:
Ionic components are formed up of ions, which are charged particles formed whenever an atom (or group of atoms) acquires or loses electrons.
Polyatomic ions were covalently bonded groupings of atoms. It has a positive or negative charge as little more than a result of an ionic bond with the other ion. Polyatomic positive ions are formed from certain ion combinations, however, the polyatomic ion acts as just a single unit.Therefore, the final answer is "ionic compounds".

Jim had 360 stamps he sold 1/3 of them on Monday and 1/4 of the remainder on Tuesday how many stamps did he sell on Tuesday
Answer:
60
Step-by-step explanation:
Since Jim sold 1/3 of his stamps on Monday, the remainder would be 2/3 of his total stamps.
Divide 360 stamps by 3. Minus the stamps sold on Monday from 360 to get the remainder.
stamps sold on Monday = 360 ÷ 3 = 120
remainder = 360 - 120 = 240
He sold 1/4 of the remainder on Tuesday.
Divide the remainder by 4.
stamps sold on Tuesday = 240 ÷ 4 = 60
He sold 60 stamps on Tuesday.

What is the equation of the line if slope is -2 and y-int is 9
Answer:
y = -2x + 9
Step-by-step explanation:
Let's start from the -2x, the slope is -2. The x is basically what says, this is the slope. The plus nine is the y-intercept. If you think in graph terms (which is how you solve this problem) you will see that on the y-axis the line will intercept at the 9. The every x integer it goes down it goes that times two. For example, if you go sideways 1 spot, the line will be at y=11.
The area of a rectangle that has a length of 10 and a width of w.
Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.

Find the area of a triangle with a base of 27 ft and a height of 14 ft. 41 ft2 82 ft2 189 ft2 378 ft2
Answer:
The answer is 189 ft²Step-by-step explanation:
The area of a triangle can be found by using the formula
[tex]A = \frac{1}{2} \times bh[/tex]
where
b is the base
h is the height
From the question
b = 27 ft
h = 14 ft
Substitute the values into the above formula and solve
That's
[tex]A = \frac{1}{2} \times 27 \times 14 \\ = \frac{1}{2} \times 378 [/tex]
We have the final answer as
189 ft²Hope this helps you
