Answer:
-x
Step-by-step explanation:
Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.
Subtract the coefficient of each terms:
1x - 2x = -1x
-x is your simplified form.

If a 50 kg object is at a location 25,600 km from Earth’s center, what is the gravitational force exerted by the object on Earth? In what direction does that force act?
Answer:
Approximately [tex]30\; \rm N[/tex] toward the center of the object.
Step-by-step explanation:
Look up the gravitational constant and the mass of the earth:
[tex]\begin{aligned}G &\approx 6.67 \times 10^{-11}\; \rm m^{3} \cdot kg^{-1} \cdot s^{-2} \\ &= 6.67 \times 10^{-11} \; \rm N \cdot m^{2} \cdot kg^{-2}\end{aligned}[/tex].
[tex]M \approx 5.97 \times 10^{24}\; \rm kg[/tex].
Convert the unit of distance to standard units:
[tex]\begin{aligned}r &= 25600\; \rm km \\ &= (25600 \times 10^{3})\; \rm m \\ &= 2.56 \times 10^{7}\; \rm m\end{aligned}[/tex].
Consider two spherical objects with mass [tex]m_{1}[/tex] and [tex]m_{2}[/tex]. Let [tex]r[/tex] denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:
[tex]\begin{aligned}F &= \frac{G \cdot m_{1} \cdot m_{2}}{r^{2}}\end{aligned}[/tex].
Thus, the size of the gravitational force between this object and the earth would be:
[tex]\begin{aligned}F &= \frac{G \cdot m \cdot M}{r^{2}} \\ &\approx \frac{1}{2.56\times 10^{7}\; \rm m} \\ &\quad \times 6.67 \times 10^{-11}\; \rm N \cdot m^{2}\cdot kg^{-2} \\ &\quad \times 50\; \rm kg \times 5.97 \times 10^{24}\; \rm kg \\ &\approx 30\; \rm N\end{aligned}[/tex].
Since gravitational force is attractive, the [tex]50\; \rm kg[/tex] object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this [tex]50\; \rm kg\![/tex] object.
Nicole is making tuna salad for her office colleagues. It takes 2/5 of a pound of canned tuna to make 5 portions of salad. She uses 6/5 pounds of canned tuna for every 2 onions used.
If Nicole uses a total of 4 onions, then how many portions of salad does she make?
A.
30 portions
B.
25 portions
C.
35 portions
D.
15 portions
Answer:
She makes 30 portions.
Step-by-step explanation:
To find, you would multiply the amount of tuna you need by the number of onions nicole used.
6/5x2 = 12/5
12/5 ÷ 2/5 = 6
6x5 = 30
She makes 30 portions.

Solve the following question:
Answer:
x = 2, x = 8
Step-by-step explanation:
reminder that f'(x) = [tex]m_{tangent}[/tex]
Differentiate f(x) term by term using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
f(x) = [tex]\frac{1}{3}[/tex] x³ - 5x² + 2x + 10
f'(x) = x² - 10x + 2
Equating f'(x) to - 14
x² - 10x + 2 = - 14 ( add 14 to both sides )
x² - 10x + 16 = 0 ← in standard form
(x - 2)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 8 = 0 ⇒ x = 8
What is the value of x?
Answer:
D. 16
Step-by-step explanation:
1. Because these are vertical angles (opposite pair of angles that are formed by intersecting lines), these are congruent. That means (8x-8) = (7x+8).
2. (Solving)
Step 1: Subtract 7x from both sides.
[tex]8x-8-7x=7x+8-7x[/tex] [tex]x-8=8[/tex]Step 2: Add 8 to both sides.
[tex]x - 8 + 8 = 8 + 8[/tex] [tex]x = 16[/tex]Step 3: Check if solution is correct.
[tex]8(16)-8=7(16)+8[/tex] [tex]128-8 = 112+8[/tex] [tex]120 = 120[/tex]Therefore, the answer is D. 16.
If Ann is traveling at 120 km/hr, what
distance does she travel in 10 minutes?
Answer:
20 km
Step-by-step explanation:
120 km an hour = 120 km in 60 minutes
120 = 60
x = 10
120/60 = 2
10*2 = 20
Answer:
20 km.
Step-by-step explanation:
120 km per hour.
An hour is 60 minutes.
To get from 60 to 10, divide 6.
Likewise, to find the distance travelled in 10 minutes, divide 120 by 6.
[tex]\frac{120}{6}= 20[/tex]
Therefore, Ann travels 20 km in 10 minutes.
9. Rashida bought 4 tickets to a concert for $80. At this rate, how much would 5 tickets cost?
Number of Tickets
4.
5
Money Spent (5)
80
Answer:
$100
Step-by-step explanation:
4 tickets cost $80.
We divide $80 by 4 to find the cost of 1 ticket.
$80/4 = $20
1 ticket costs $20.
Now we multiply $20 by 5 to find the cost of 5 tickets.
5 * $20 = $100
Answer: $100

Are the points (3,2) (8,16) (13,8) (14,14) (20,5) (24,8) (27,2) (31,6) (31,3) a function?
Answer:
No, The domains of a same number are said twice.
Step-by-step explanation:
If it is the range (y) it doesn't matter twice or not.
Answer:
The given relation is not a function.
Step-by-step explanation:
Given the relation: {(3,2) (8,16) (13,8) (14,14) (20,5) (24,8) (27,2) (31,6) (31,3)}
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? In this case, the answer is no. The input value (x = 31) goes with two output values, 6 and 3. It only takes one input or x-value to associate with more than one output value to be invalid as a function.Another way to find out whether a relation or a set of given points represent a function through the Vertical Line Test. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.
To use the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value. If you do this for the given set of points, every vertical line intersects the graph in at most one point, except for the x-value = 31, where the vertical line contains two points (in red dots) in it: (31,6) and (31,3). The given graph fails the Vertical Line Test, which means that it is not a function.
Attached is a screenshot of the graph where I performed the Vertical Line Test.
