Answer:
A
Step-by-step explanation:
the "-" sign simply turns everything upside-down. what was above the x-axis is now below it. and vice versa. hence, a reflection over the x-axis.
the "+6" moves then everything up by 6 units. which is a vertical shift up by 6 units.

What is the value of X?
Solution:
Note that:
3x + 50 = 6x - 10 (Vertically opposite angles)Simplify the equation to find x.
Add 10 both sides.
3x + 50 = 6x - 10=> 3x + 50 + 10 = 6x - 10 + 10=> 3x + 60 = 6xSubtract 3x both sides.
3x + 60 = 6x=> 3x - 3x + 60 = 6x - 3x=> 60 = 3xDivide 3 both sides.
60 = 3x=> 60/3 = 3x/3=> x = 20Answer:
x = 20Step-by-step explanation:
opposite angles = equal angles
we solve with a proportion
3x + 50 = 6x - 10
50 + 10 = 6x - 3x
60 = 3x
x = 60 : 3
x = 20

What is the area of the figure At the right explain how you found your answer use the formula A = 1/2 bh to find the area of the triangle and A = bh for the area of a parallelogram
By comparing the figure with simpler shapes (rectangles and triangles) we will see that its area is 30ft^2.
How to get the area?
The area of the figure will be equal to the difference between the area of a 5ft by 10 ft rectangle, and the area of the 3 triangles that can be formed.
The area of a 5ft by 10ft rectangle is:
A = 5ft*10ft = 50ft^2
For the 3 triangles we have:
2 triangles with a base of 5ft - 3ft = 2ft, and a height of 10ft/2 = 5ft.
(these are the two left triangles).
Remember that for a triangle of base b and height h, the area:
A = b*h/2
Then for each of these triangles, the area is:
A' = (2ft*5ft)/2 = 5ft^2
And we have two of these, so the areas add up to 10ft^2.
For the right triangle, we can see that its base measures 10 ft, and its height is of 2 ft, then its area is:
A'' = (10ft*2ft)/2 = 10ft^2
Then the area of the figure is:
Area = A - 2A' - A'' = 50ft^2 - 2*(5ft^2) - 10ft^2 = 30ft^2

Answer:
a for the fist c for 2 d for 3 and idontknow
4
Step-by-step explanation:
===================================================
Explanations:
Problem 1
v = 9i - 4j means we move 9 units to the right and 4 units down.
Another way to write this is v = <9, -4>
----------------------
Problem 2
R = (-19, 6)
S = (-35, 13)
Subtract x coordinates: xS - xR = -35 - (-19) = -16
Subtract y coordinates: yS - yR = 13 - 6 = 7
Those results form the vector v = -16i + 7j
This vector indicates we move 16 units left and 7 units up when going from point R(-19,6) to point S(-35,13).
----------------------
Problem 3
t = -5i + 12j
||t|| = sqrt( (-5)^2 + (12)^2 )
||t|| = 13
theta = arctan(12/(-5))
theta = -67.38
Add on 180 to get to the proper quadrant Q2
-67.38 + 180 = 112.62
Therefore,
[tex]t = 13\bigg\langle \cos(112.62^{\circ}), \ \sin(112.62^{\circ})\bigg\rangle[/tex]
----------------------
Problem 4
The x, y components are the coefficients of the linear form.
This allows us to go immediately from <-39,16> to -39i + 16j
----------------------
Problem 5
P = (-5,11)
Q = (-16,4)
Subtract x coords: xQ - xP = -16 - (-5) = -11
Subtract y coords: yQ - yP = 4 - 11 = -7
The component form of vector t is <-11, -7> and this vector is in Q3.
r = sqrt(a^2 + b^2)
r = sqrt( (-11)^2 + (-7)^2 )
r = 13.038 is the approximate length of the vector.
theta = arctan(b/a)
theta = arctan(-7/(-11))
theta = 32.471
Add on 180 so we get to Q3
32.471+180 = 212.471
Therefore, we have
[tex]x = r\cos(\theta) = 13.038\cos(212.471^{\circ})\\\\y = r\sin(\theta) = 13.038\sin(212.471^{\circ})\\\\t = xi + yj\\\\t = 13.038\cos(212.471^{\circ})*i + 13.038\sin(212.471^{\circ})*j\\\\[/tex]
in which you could write into this slightly more compact form
[tex]t = 13.038\bigg\langle\cos(212.471^{\circ}),\sin(212.471^{\circ})\bigg\rangle\\\\[/tex]

The probability of an event is 84%. Describe the likelihood of the event.
Answer:
Please read below.
Step-by-step explanation:
P(event)= favorable outcomes / total outcomes
0.84 * 100 = 84
100 - 84 = 16
84 favorable outcomes
16 unfavorable outcomes
100 total outcomes
Therefore there is a 84% chance of it happening.
Therefore there is a 16% chance of it not happening.
P(event) = 84/100
8.4 out of 10
Describe it how ever you want. 8.4 out of 10 is a pretty good bet to me. I would put my money on it. There isn't a lot of context to the question. But, I hope this helps!
It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.
What is probability?Probability is to measure the occurrence of an event.
It is given that
probability of an event = 84% or 0.84
This means, P(E) = 0.84
Number of favorable outcomes/ Total outcomes =84
Let us say Total outcomes are 1000
So favorable outcomes = 1000*0.84
Favorable outcomes = 840
Therefore, It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.

What is the LEADING COEFFICIENT of the polynomial: 2x^2y - 7x^2y^3 + 6xy^2
Answer:
-7
Step-by-step explanation:
Leading coefficient: the number written in front of the variable with the largest degree.
If a term has two or more variables, its degree is the sum of the exponents of its variables
For [tex]2x^2y - 7x^2y^3 + 6xy^2[/tex]
The degree of the first term of the polynomial is 3 (2 + 1 = 3)The second term of the polynomial is of degree 5 (2 + 3 = 5)The third term of the polynomial is of degree 3 (1 + 2 = 3)Therefore, the leading coefficient is -7 since the greatest sum of the exponents is of the second term.
[tex]\mathbb{FINAL\;ANSWER:}[/tex]
[tex]\huge\boxed{\sf{The\;coefficient\;is\;-7}}[/tex]
[tex]\mathbb{SOLUTION\;WITH\;STEPS:}[/tex]
Hi! Hope you are having a nice day!
The leading coefficient of the given polynomial is -7.
Why? Because the leading coefficient is the number written before the variable with the largest exponent.
In this case, it's -7, because it's written next to a term that's cubed, and that's the largest exponent in the polynomial.
Also, if a term has two variables (or more) then we add the exponents in that term in order to get the degree of the term.
In this case, it's 5.
Hope you could understand everything.
