Answer:
There are 0.5 ounces in 14 grams.
Step-by-step explanation:
Ounce is a larger unit while gram is a smaller unit. When we have to convert from a smaller unit to a larger unit, division is used.
It is also given that
1 ounce = 28 grams
In order to find the number of ounces in 14 grams, it will be divided by 28 grams
So,
[tex]14\ grams = \frac{14}{28} = 0.5\ ounces[/tex]
Hence,
There are 0.5 ounces in 14 grams.

Which of the following statements best describes the value of the expression 7x + 6 when x = 5? A. The result is a fraction. B. The result is a prime number. C. The result is a composite number. D. The result is a whole number that is neither prime nor composite.
Answer: B) The result is a prime number
==================================================
Explanation:
Replace x with 5. Then use PEMDAS to simplify.
7x+6
7*5+6
35+6
41
The expression 7x+6 is equal to 41 when x = 5.
The value 41 is prime because its factors are only 1 and 41.

Step-by-step explanation: But what is the sum?
Given segment AB with points (-4, 8) and (6,3) respectively. Find the
coordinates of point P that partitions Segment AB in the ratio 3:2. The answer should be entered in the form (x,y) with out any spaces between characters.
Answer:
The answer is "Coordinates of point P= (2,5)"
Step-by-step explanation:
We are familiar with the internal division of AB by point P, i.e. 3:2, [tex]\frac{AP}{PB}= \frac{3}{2}[/tex]
Therefore, we use the internal division formula.
Points:
[tex]\to (-4,8) \ and \ (6,3)\\\\ x_1 = -4\\y_1 = 8\\x_2= 6\\y_2 =3 \\[/tex]
Formula:
[tex]\to x = \frac{(mx_2 + nx_1)}{(m + n)}\\\to y = \frac{(my_2 + ny_1)}{(m + n)}\\\\where,\\\\\to m = 3 \\ \to n = 2[/tex]
Replacing the x coordinate representations of A and B with x, we have
[tex]x = \frac{(3 \times 6 + 2 \times (-4))}{(3 + 2)}\\\\[/tex]
[tex]= \frac{(18 - 8)}{5}\\\\ = \frac{10}{5}\\\\ = 2[/tex]
Replacing the, y coordinate representations of A and B with y, we have
[tex]y = \frac{(3 \times 3 + 2 \times 8)}{(3 + 2)}\\\\[/tex]
[tex]= \frac{( 9 +16)}{(5)}\\\\= \frac{25}{5}\\\\=5[/tex]
The coordinates of point P= (2,5).

Let f(x) represent the weight of the jar when there are x marbles, where f(0)=10. Which equation correctly represents f(x) in terms of f(x−1) for all x>0?
A
f(x)=3⋅f(x−1)
B
f(x)=f(x−1)+3
C
f(x)=f(x−1)+3x
D
f(x)=f(x−1)+2x+1
Answer:
B
Step-by-step explanation:
We essentially have the sequence:
10, 13, 16, 19, 22,25...
This is an arithmetic sequence because each subsequent term differs only by a constant.
And this constant, the common difference, is +3 since each subsequent term is 3 more than the previous term.
Hence, we can write a recursive formula for our sequence.
We will first define our first term. The first term, at x=0, is 10. Hence:
[tex]f(0)=10[/tex]
Each term, x, is +3 the previous term (x-1). Therefore:
[tex]f(x)=f(x-1)+3[/tex]
Hence, our answer is B.
Answer:
B
Step-by-step explanation:
f(x)=f(x-1)+3x

Answer:
x = 9
Step-by-step explanation:
84 + (7x + 5) + (180 - (17x-1)) = 180
84 + 7x + 5 + (181 - 17x) = 180
270 + (-10x) = 180
90 = 10x
x = 9

Step-by-step explanation:
If the graph of the function f has a multiple zero at x = 2, what is a possible exponent of the factor x - 2? Justify your reasoning.
Answer:
[tex](x-2)^2[/tex]
The exponent is 2.
Step-by-step explanation:
Remember multiplicity rules:
If a factor has an odd multiplicity (e.g. it is raised to 1, 3, 5...) then it will cross the x-axis. If a factor has an even multiplicity (e.g. it is raised to 2, 4, 6...) then it will bounce off the x-axis.At x=2, we have the factor (x-2).
From the graph, we can see that the graph bounces off at that point.
Hence, the multiplicity of (x-2) must be even.
Therefore, a possible exponent for the factor (x-2) is 2. Any even number will suffice.
COMPLETE THE TABLE PICTURED: A robot is put into a maze, it can only go N, E, S, and West. The value i represents the north, and the magnitude is equal to 1. I have figured out that N= i, East= 1, South= -i, and West= -1. When programming the robot, let the complex number d represent the direction the robot is facing. As the robot changes direction, the value of d will also change; so, the value of d is dependent on where the robot is in the maze. When the robot makes a turn, it would be useful to have an operation to perform on d to represent this turn. This is because after making a turn, the new value of d will depend on the old value of d. Complete the table for the new values of d if the robot is turning left or right. Then determine an expression in terms of d that will give the new position if the robot turns left and another expression if the robot turns right. Type these expressions in the last row of the table.

Answer:
see attached
Step-by-step explanation:
A right turn represents a clockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by -i.
A left turn represents a counterclockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by i.
The attached table shows the desired values and expressions.
Step-by-step explanation:
[tex]\boxed{\begin{array}{c|c|c} \underline{Intial -d} & \underline {Left-turn} & \underline{Right-turn} \\ -1 & -i & i \\ 1 & i & -i \\ i & -1 & 1\\ -i & 1 & -1 \\ d & di & -di \end{array}}[/tex]

Answer:
Equation: x + 2 = 7/8x - 15
Solution: x = -136
Explanation:
x + 2 = 7/8x - 15
2 + 15 = 7/8x - x
17 = 7/8x - 8/8x
17 = -1/8x
17 × -8 = x
-136 = x
Slope is 2, and (5, 3) is on the line.
Answer:
3 = 2(5) + b
Step-by-step explanation:
Equation for a slope is y=mx+b.
Y = Y-value on the graph
M = The slope
X = X-value on the graph
B = Y-intercept
If the coordinates are ( x, y )
Then that must mean that x = 5 and y = 3 because the numbers would replace the variables in the same order
The B-value is unknown for now but you are able to find it by solving this algebraically.
3=2(5) + b
3 = 10 + b
-10 = -10 + b
-7 = b
Because the 10 and the -10 would cancel each other. Leaving you with only -10 on the other side.
I hope that this helps.

Answer:
Step-by-step explanation:
Since we don't know x, let's come up with our own.
Lets chose 6 for x.
Now, let's plug in 6: y = 2 * 6 - 7
Multiply: y = 12 - 7
Subtract: y = 5
So our first point is (6, 5)
Now lets choose a second x: 5
Plug it in: y = 2 * 5 - 7
Multiply: y = 10 - 7
Subtract: y = 3
So our second point is (5, 3)
Find both of these points and your answer should look like the attached image.

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.
Answer:
First, these angles are alternate interior angles.
[tex] 10x - 5 = 9x + 1 [/tex]
[tex] x = 6 [/tex]
Step-by-step explanation:
(10x - 5)° and (9x + 1)° are alternate interior angles. Thus, they are congruent to each other.
Thus, to find x, we will set each angle equal to the other.
[tex] 10x - 5 = 9x + 1 [/tex]
Solve for x. Collect like terms
[tex] 10x - 9x = 5 + 1 [/tex]
[tex] x = 6 [/tex]
