if f(x) = -3x - 5 and g(x) = 4x-2, find (f+g)(x)
Answer:
(f+g)(x) = x - 7
Step-by-step explanation:
it is simple - when adding 2 functions your simply add both expressions. and the result is then the function of the sum.
the same applies also to other arithmetic operations.
-3x -5 + 4x - 2 = x - 7

Find the image of (−3, 8) after a 270∘ rotation counterclockwise about the origin.
Answer:
(8, 3)
Step-by-step explanation:
For a 270° rotation, the rule is that (x, y) turns into (y, -x)
In (-3, 8), -3 represents x and 8 represents y.
Our answer is then (y, -x), or (8, 3)

Step-by-step explanation:
The base of a 40-foot ladder is placed 24 feet away from a wall. What is the
height of the wall if the other end of the ladder reaches the top of it?
A. 32 ft
B. 64 ft
C. 16 ft
D. 26 ft
Answer:
A. 32 ft
Step-by-step explanation:
Pythagoras for right-angled triangles (as that is what this is here - the floor from the base of the ladder to the wall, the wall up to where the ladder ends, and the ladder itself as the Hypotenuse).
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
so, we know,
c = 40 ft
a = 24 ft
we are looking for B
=>
40² = 24² + b²
1600 = 576 + b²
1024 = b²
b = 32 ft

Marina spent 1/5 of her money on a book. If she had $80 left after she brought the book, how much money did she have originally?
Answer:
Marina had 50$ originally
Step-by-step explanation:
80-1/5 of the money she spent for the books that she brought, The step by step process is how much money she had left behind from the books she brought seperate
Answer:
$100
Step-by-step explanation:
Step 1, setting up an equation:
If Marina spent [tex]\frac{1}{5}[/tex] of her money, she has [tex]\frac{4}{5}[/tex] of her money remaining. We also are given that she has $80 left. We can set her initial total amount of money as x to solve this problem:
[tex]\frac{4}{5}x=80[/tex]
Step 2, solving for x:
[tex]\frac{4}{5}x=80\\\\4x=400\\\\x=100[/tex]
We have set x as her original amount of money, so we have the answer!
Marina originally had [tex]\fbox{100}[/tex] dollars.

-11 + x = 7X - 5
I don't know what your looking for, so be more specific, but I'm assuming your solving for x, so that's would be
x = -1
Answer:
We can simply solve all of these by simplifying them :)
1 . 13 - 4x = 1 - x =
x = 4
2 . 7a - 3 = 3 + 6a =
a = 6
3 . 5 + 2x = -2x + 6 =
x = 1/4
4 . -11 + x = 7x - 5 =
x = -1

f(x) = 4 - 2x – 2x3
g(x) = x² + 7x-9
Find f(x) + g(x).
Answer:
-2x^3+x^2+5x-5
Step-by-step explanation:
f(x) = 4 - 2x – 2x^3
g(x) = x² + 7x-9
f(x) + g(x)=4 - 2x – 2x^3+ x² + 7x-9
Combine like terms
f(x) + g(x) = -2x^3+x^2+5x-5
12s + 10t = 54
6s + 10t = 42
What is a and what is t
Answer:
First equation has extra 6s and this extra 6s=54-42=12
6s=12. s=2
Step-by-step explanation:
6*2+10t=42 ........ 10t=30 t=3
Answer:
s = 2 and t = 3
Step-by-step explanation:
Assuming you were suppose to type s instead of a,
12s + 10t = 54 -- (1)
6s + 10t = 42 -- (2)
(1) - (2) : 6s = 12
s = 2 -- (3)
Substituting (3) into (2),
12 + 10t = 42
10t = 30
t = 3 -- (4)
Therefore, s = 2 and t = 3

Graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to xxx is 5/3 In other words, a change of 1 unit in x corresponds to a change of 5/3 units in y. Graph the line and write the equation of the line.
Use numbers 1-9 in the graph negative and positive THANK YOU
Answer:
The equation of the line is, "y = 5/3x."
Step-by-step explanation:
Here are the pictures of the graph and points attached:
If a line has an x-intercept at =
3 and a y-intercept at y = – 5, find its equation in the form
y = mx + b.
y
Answer:
y = 5/3x - 5
Step-by-step explanation:
y = mx + b
b = y-intercept
m = slope
y = mx - 5
plug in the x-intercept
0 = m(3) - 5
5 = 3m
m = 5/3
y = 5/3x - 5
graph is below, both intercepts are on the line

Step-by-step explanation:
Distribution of Sample Proportions
Susan really loves the lemon-flavored Fruity Tooty candies, but there always seems to be a lot of grape-flavored candies in each bag. To determine whether this is because grape candies are so popular or because each bag contains fewer lemon candies, Susan randomly picks a Fruity Tooty candy from her bag, records its flavor, and places it back in the bag. Each bag contains a mixture of cherry, grape, apple, lemon, and orange flavors. Which statement about Susan's distribution of sample proportions is true?
a) The distribution of the count of picking a cherry candy cannot be modeled as approximately normal if Susan picks candies over 200 times.
b) The distribution of apple candy can be modeled as normal if Susan picks candies over 75 times.
c) The sample proportion of drawing an orange candy is not a binomial distribution.
d) The distribution of lemon candy can be modeled as normal if Susan picks candies 10 times.
Answer:
Option B, The distribution of apple candy can be modeled as normal if Susan picks candies over 75 times
Step-by-step explanation:
The distribution of apple candies can be represented as normal curve and hence the sample proportion for this is true and can be drawn.
The rest other cases do not represent a normal distribution and hence it will not be easy to plot curve for these samples.
hence, option B is correct

Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10?
A. -10, -12, -14, -16, -18, ...
B. -2, 8, 18, 28, 38, ...
C. 8, 18, 28, 38, 48, ...
D. 10, 8, 6, 4, 2, ...
Not sure the answer
HELP!!
Answer:
D. 10, 8, 6, 4, 2, ...
Step-by-step explanation:
f(n + 1) = f(n) - 2
This means that each term is the previous term subtracted by 2,
f(1) = 10
This means that the first term of the sequence is 10.
Thus, the sequence is:
10, 8, 6, 4, 2, ...
Thus the correct answer is given by option D.
In a completely randomized design, experimental units were used for the first treatment, for the second treatment, and for the third treatment. Complete the following analysis of variance (to 2 decimals, if necessary). If the answer is zero enter "0". Source of Variation Sum of Squares Degrees of Freedom Mean Square F p-value Treatments Error Total At a level of significance, is there a significant difference between the treatments? The -value is - Select your answer - What is your conclusion?
Answer: hello your question is poorly written attached below is the complete question
answer:
i) Degrees of freedom : 2, 46 , 44
ii) Mean square : 650 , 13.4
iii) F = 47.65
Step-by-step explanation:
First treatment = 12 experimental units
Second treatment = 15 experimental units
Third treatment = 20 experimental units
completing the analysis
i) Degree of freedom
for Treatments = 3 - 1 = 2
for Total = ( 12 + 15 + 20 ) - 1 = 47 - 1 = 46
for error = 46 -2 = 44
ii) Mean square
for treatments = sum of squares / degree of freedom = 1300/2 = 650
for error = 600 / 44 = 13.64
iii) F
= Ms of treatment / Ms of error
= 650 / 13.64 = 47.65
