Which intervals is this function graph decreasing? Select 2 answers. *
[ -5.5, -5]
[ -5, -4]
[ -3, 1]
[1,2]
Choice B. [-5, -4]
Choice D. [1, 2]
===================================================
Explanation:
We're looking for portions when the graph goes downhill when we move from left to right.
The first portion is from x = -5 to x = -4. So we write [-5, -4] which represents [tex]-5 \le x \le -4[/tex]
The second portion is [1, 2] which goes downhill since the interval starts at x = 1 and stops at x = 2.
The portions are highlighted in the diagram below.
As you can see, we only care about the x values for any given interval. The y values don't matter as long as they decrease along the interval.

which of the following is an equation of the line that passes through the point (2,2) and is parallel to the graph of the equation y = 3x-1?
Answer:
y=3x-4
Step-by-step explanation:
2=3(2)+b
2=6+b
-4=b
parallel lines have the same slope, so 3/1 would be slope
y=mx+b
y=3x-4
Find the radian measure of the angle with the given degree measure. Round your answer to three decimal places.
Answer:
-0.663rad
Step-by-step explanation:
The angle in question is -38°
Using the conversion formula
πrad = 180°
xrad = -38°
Cross multiply
180 × x = -38π
x = -38π/180
x = -19π/90
x = -0.6632251158
Hence the radian measure of the angle to three decimal place is -0.663rad

F. P(E)/P(E') = 1
G. P(E') = 1/P(E)
Answer:
Options A, C & E
Step-by-step explanation:
For the probability of an event E which is denoted by: P(E).
In complementary events, the complement of E is denoted by: P(E').
Now, the complement means the outcome that Event E does not occur.
This means that the sample space is 1.
Thus;
P(E) + P(E') = 1
It can be rewritten as;
P(E') = 1 - P(E)
It can also be written as;
P(E) = 1 - P(E')
The correct options are; A, C & E

Plot two points that are 6 units from Point B and also share the same y-coordinate
as Point B.
Please help
Answer:
2 9 and 2 -3
Step-by-step explanation:
ggs in the chat
The two points that are 6 units from Point B (1, 3) and share the same y-coordinate are (-5, 3) and (7, 3).
To plot two points that are 6 units from Point B (1, 3) and share the same y-coordinate, we need to find the points that are located 6 units to the left and right of B while having the same y-coordinate of 3.
Point to the left of B: (1 - 6, 3) = (-5, 3)
Point to the right of B: (1 + 6, 3) = (7, 3)
So, the two points that satisfy the conditions are (-5, 3) and (7, 3).

Which ordered pair is a solution of the equation?
7x-2y= -5
Answer:
Neither
Step-by-step explanation:
To check whether an ordered pair (a,b)(a,b)left parenthesis, a, comma, b, right parenthesis is a solution of an equation, substitute these values into the equation and determine if the resulting equality is true or false.
To check whether (\blue{1},\pink{5})(1,5)left parenthesis, start color #6495ed, 1, end color #6495ed, comma, start color #ff00af, 5, end color #ff00af, right parenthesis is a solution of the equation, let's substitute \blue{x}=\blue{1}x=1start color #6495ed, x, end color #6495ed, equals, start color #6495ed, 1, end color #6495ed and \pink{y}=\pink{5}y=5start color #ff00af, y, end color #ff00af, equals, start color #ff00af, 5, end color #ff00af into the equation:
\begin{aligned}7\blue{x}-2\pink{y}&=-5\\ 7\cdot\blue{1}-2\cdot\pink{5}&=-5\\ 7-10&=-5\\ -3&=-5\end{aligned}
7x−2y
7⋅1−2⋅5
7−10
−3
=−5
=−5
=−5
=−5
Since -3\neq-5−3
=−5minus, 3, does not equal, minus, 5, we obtained a false statement, so (1,5)(1,5)left parenthesis, 1, comma, 5, right parenthesis is not a solution of the equation.
Hint #33 / 4
To check whether (\blue{-1},\pink{1})(−1,1)left parenthesis, start color #6495ed, minus, 1, end color #6495ed, comma, start color #ff00af, 1, end color #ff00af, right parenthesis is a solution of the equation, let's substitute \blue{x}=\blue{-1}x=−1start color #6495ed, x, end color #6495ed, equals, start color #6495ed, minus, 1, end color #6495ed and \pink{y}=\pink{1}y=1start color #ff00af, y, end color #ff00af, equals, start color #ff00af, 1, end color #ff00af into the equation:
\begin{aligned}7\blue{x}-2\pink{y}&=-5\\ 7\cdot(\blue{-1})-2\cdot\pink{1}&=-5\\ -7-2&=-5\\ -9&=-5\end{aligned}
7x−2y
7⋅(−1)−2⋅1
−7−2
−9
=−5
=−5
=−5
=−5
Since -9\neq-5−9
=−5minus, 9, does not equal, minus, 5, we obtained a false statement, so (-1,1)(−1,1)left parenthesis, minus, 1, comma, 1, right parenthesis is not a solution of the equation.
Neither of the ordered pairs is a solution of the equation.
Neither of the ordered pairs (1, 5) and (-1, 1) is a solution to the equation 7x - 2y = -5. The correct option is 4.
An ordered pair is a pair of numbers that represents a point in a coordinate system. It is written in the form (x, y), where 'x' is the horizontal value (abscissa) and 'y' is the vertical value (ordinate). The order of the numbers is essential, as switching their positions creates a different point.
equation: 7x - 2y = -5
For (x = 1, y = 5):
7(1) - 2(5) = 7 - 10 = -3 (Not equal to -5).
(x = -1, y = 1):
7(-1) - 2(1) = -7 - 2 = -9 (Not equal to -5).
Since neither ordered pair satisfies the equation 7x - 2y = -5, the correct answer is 4. neither.

The art club decides to sell calendars as a fundraiser. The initial cost to
make the calendars is $605 for equipment with an additional materials cost
of $2.50 per calendar. If the club plans to sell the calendars for at least $8
a piece, how many would they need to sell to break even?
Answer:
I got 106 calendars
Step-by-step explanation:
605 divided by 2.50 = 242. Next you have to add what you got to the initial cost. Then we get 847. Next you have to divide this by 8 and round up, and i got 106. I might be wrong XD
They need 110 calendars to reach $1200.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
The initial cost to make the calendars is $605 for equipment with an additional materials cost of $2.50 per calendar.
We have to raise at least 1200$.
let x be the number of calendars.
Then, the inequality is,
8x - 2.5 x + 600 ≥ 1200
Solving we get,
5.5x≥ 600
x ≥ 109.09
x ≥ 110

What are the first 4 terms of an arithmetic sequence with a pattern of -6 if the first term is 76
Answer:
76, 70, 64, 58.
Step-by-step explanation:
By pattern I guess you mean common difference.
The first term is 76 so the second is 76-6 = 70, then we have 70-6 = 64 and so on.
The first 4 terms in an arithmetic sequence are 70, 64, 58, 52.
What is an arithmetic sequence?
An arithmetic sequence is a sequence where every two consecutive terms have the constant difference between them.
Here the first term = 76 and the common difference is = -6.
Therefor,
The 2nd term is = 70.
The 3rd term is = 64.
The 4th term is = 58.
The 5th term is = 52.

Let sin(2x) = cos(x), where 0° ≤ x < 180°. What are the possible values for x?
30° only
90° only
30° or 150°
30°, 90°, or 150°
Double angle identity for sine:
sin(2x) = 2 sin(x) cos(x)
So rewrite the equation as
sin(2x) = cos(x)
2 sin(x) cos(x) = cos(x)
2 sin(x) cos(x) - cos(x) = 0
cos(x) (2 sin(x) - 1) = 0
There are two cases,
cos(x) = 0 or 2 sin(x) - 1 = 0
cos(x) = 0 or sin(x) = 1/2
In the interval 0º ≤ x < 180º, we have cos(90º) = 0 and sin(30º) = sin(150º) = 1/2, so the possible values are 30º, 90º, or 150º.

Sarah accepted a new job at a company with a contract guaranteeing annual raises.
Sarah's salary after working for n years can be determined using the equation
S = 90000 + 3500n. What is the slope of the equation and what is its
interpretation in the context of the problem?
Answer:
The answer is below
Step-by-step explanation:
A linear equation is in the form of y = mx + b, where y is a dependent variable (that is it depends on other variable), x is an independent variable (that is it does not depend on any variable), m is the slope (rate of change) and b is the value of y at x =0
Given that S is salary, n is number of working years. It is given by:
S = 90000 + 3500n
the slope = 3500
The equation means that Sarah's beginning salary is 90000 and the salary increases by 3500 each year
