Answer:
B - 34 years old
Step-by-step explanation:
First you have to multiply 42 times 3 to find the total age of the three people. Then multiply 40 times 4 to find the age of the four people in all. Subtract.
42 × 3 = 126
40 × 4 = 160
160 - 126 = 34

What is 3.6 = 2.4x step by step please
Answer:
x = 1.5
Step-by-step explanation:
3.6 = 2.4x
divide by 2.4 on both sides
you get 1.5
x = 1.5
Check it if u want
Answer:
x=1 1/2
Step-by-step explanation:
3.6 / 2.4 = x
Convert by factor:
3.6 = 1.2x3
2.4 = 1.2x2
3/2 = x
x = 1 1/2

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
a. f(–3) = –5
b. f(–3, –5) = –8
c. f(–5) = –3
d. f(–5, –3) = –2
Answer:
a. f(–3) = –5
Step-by-step explanation:
On a graph, point (x, y) can be also represented as function f (x) = y
it means that if f(x) has input value as x then its output value will be y.
Now given that in the problem that
The point (–3, –5) lies on the graph
it means that for function input value of of -3 has the out put value of -5
which can also be written as
f(-3) = -5
Hence the correct choice is a. f(–3) = –5.

Answer:
153/20
Step-by-step explanation:
We want to have the mixed fraction turned into a improper fraction to make adding them both easier. We would change 5 2/8 to 42/8 and 2 4/10 to 24/10.
We now need to get them a common denominator. The LCM (least common multiple) of 8 and 10 is 40, so we multiply 42/8 by 5/5 getting us 210/40 and 24/10 by 4/4 to get 96/40.
Finally, we add them then simplify. 96/40 + 210/40 is 306/40. We then simplify that to 153/20.

Below is the graph of a polynomial function F with real coefficients. Use the graph to answer the following questions about F. All local extrema of F are shown in the graph.
(For the last question, the multiple choice answers are ‘4,5,6,7,8,9’ I am allowed to choose more than one if needed)
(a) (-∞, -8) U (-4, 0) U (5, 9)
To find the intervals of decreasing, you just pay attention to where the graph is angled downward, when looking at it from left to right.
I usually do this by drawing lines on the x value where there is a local max/min and looking to see what the values are at that line.
You then make an ordered pair out of the two numbers.
This is the same process for finding both the increasing and decreasing intervals.
(b) -4, 5
A common mistake for this problem could be that you put the maximum and minimum x values in for this function, but the problem is only asking for the maximums.
If you look at the graph and find the point, the x-values are what you will use for this problem.
(c) +
For these kinds of problems, I draw an imaginary vertical line through the middle of the function.
If the far right and left parts of the function are going up, then the function is positive. If the far right and left parts of the function are going down, then the function is negative. If the far left part of the function is going down while the far right part of the function is going up, then the function is positive. If the far left part of the function is going up while the far right part of the function is going down, then the function is negative.These positives/negatives belong to the leading coefficient of f.
(d) 6
The degree of f relies on the number of times the function touches the x-axis.
Multiplicity: the number of times any given x-intercept appears in the equation
If an x-intercept passes through the x-axis, then that intercept has a multiplicity of 1If an x-intercept bounces off of the x-axis, then that intercept has a multiplicity of 2If an x-intercept passes through the x-axis, but flattens out when it touches the x-axis, then that intercept has a multiplicity of 3Adding up the multiplicities of all of the x-intercepts gives you the degree of the function.
In this problem, there are x-intercepts that simply pass through the x-axis at -9, -6, 8, and 10, and an x-intercept that bounces off of the x-axis at 0, which makes it a function of degree 6.
(a) The function f is decreasing over the intervals (-∞, -8), (-4, 0), and (5, 7)
(b) The function f has local maximum at x = -4, and x = 5
(c) The sign of the leading coefficient is (positive) +
(d) The possibility for the degree of the polynomial is 6
The reasons for the above selected values are as follows:
(a) A function is decreasing over an interval where the values of the function decreases simultaneously as the input value increases
From the graph, in the region for the input x-values of -∞ to -8, we have;
The output y-value decreasing from infinity to -3
Therefore, the function decreases over the interval (-∞, -8)
Similarly, between the points (-4, 2), and (0, 0), we have:
The input x-values is increasing from x = -4 to x = 0
The output y-values is decreasing from y = 2 to y = 0
Therefore, the function is decreasing over the x-interval (-4, 0)
The output y-values of the function also decreases as the input values increase between the points (5, 4) and (7, -2), which is the interval (5, 7)
Therefore, the function decreases over the interval (5, 7)
The intervals over which the function decreases are;
(-∞, -8), (-4, 0), and (5, 7)
(b) A local maxima is a point that has a larger y-value, compared to other surrounding points
The point x is a local maximum if f(x) ≥ f(z) for all z in (a, b), where a < x < b
In the interval (-8, 0), f(-4) =2 > f(-8) = -3, and f(-4) = 2 > f(0) = 0
Therefore, the point (x, f(x)) = (-4, 2) is a local maximum point
Similarly, in the interval, (0, 9), we have; f(0) = 0 < f(5) = 4 > f(9) = -2 therefore, the point (x, f(x)) = (5, 4) is a local maxima
The local maxima are (-4, 2), and (5, 4), and the function f has local maximum at x = -4, and x = 5
(c) The leading coefficient is the numerical value that multiplies the variable having the highest exponent
The sign and number type of the leading coefficient determines the end behavior
[tex]\begin{array}{cll} \mathbf{Degree \ of \ the \ polynomial}&& \mathbf{Leading \ coefficient}\\\\&\mathbf{Positive (+)}&\mathbf{Negative(-)}\\\\Even&f(x) \rightarrow \infty \ as \ x \rightarrow \pm \infty&f(x) \rightarrow -\infty \ as \ x \rightarrow \pm \infty\\\\Odd &f(x) \rightarrow \infty \ as \ x \rightarrow \infty&f(x) \rightarrow \infty \ as \ x \rightarrow -\infty\\\\Odd&f(x) \rightarrow -\infty \ as \ x \rightarrow -\infty&f(x) \rightarrow -\infty \ as \ x \rightarrow \infty\end{array}[/tex]
The end behavior of the given graph is as x → ±∞, f(x) → ∞, therefore, the
sign of the leading coefficient is positive (+)
(d) The degree of the polynomial is given by the number and nature of the graph crossing of the x-axis
The graph crosses the x-axis and appears straight across the intercept at 4 points given 4 zeros
The graph bounces of the x-axis at (0, 0), giving 2 zeros
Therefore, the total number of zeros = 4 + 2 = 6 = The degree of the polynomial
The possible degree of the polynomial = 6

Step-by-step explanation:
cos x= 3/4, s in quadrant 1
Answer: x = 41.4°
Step-by-step explanation:
We want to solve:
Cos(x) = 3/4
Such that this is on quadrant 1.
(if x is in degrees, the possible values of x will be: 0° ≤ x ≤ 90°)
To solve this we need to remember the inverse functions.
If we have two functions f(x) and g(x), these functions are inverses if:
f( g(x) ) = x
g( f(x) ) = x
Then the inverse of the cosine function (this function is "arcos(x)") is such that:
Arcos( cos(x) ) = x
Then in our equation:
Cos(x) = 3/4
We can apply the inverse function to both sides to get:
Arcos(Cos(x)) = Arcos(3/4)
x = Arcos(3/4)
(To find the Arcos function in your calculator, you need to use the button "inv" and then the "cos" button, and remember to have your calculator in deg mode)
x = Arcos(3/4) = 41.4°
C - d/x = e
Make x the subject
Answer:
x = -d(e - c)
Step-by-step explanation:
To make the x a subject, you just need to separate the x from everything else.
-d / x = e - c (subtract c from both sides)
x = -d(e - c) (multiply -d from both sides)
