When solving the equation 3x + 9 = 17x - 11, the first step is to?
Step-by-step explanation:
The first step is to move the like terms to same side of equation
3x + 9 = 17x - 11 ➡ 9 + 11 = 17x - 3x
then we add like terms
20 = 14x simplify if needed
10 = 7x and x = 10/7

The slope of the line is
The y-intercept is at
The graph represents the function
(3, 4)
(0, -3)..
Answer:
1. The slope of the line is 7/3
2. y intercept is -3
3. y= 7/3x -3
Step-by-step explanation:
To find the slope of the line you use the equation y2-y1/x2-x1
y2 and y1 are y coordinates of the 2 coordinates on the same line that you want to find the slope of and the same with x2 and x1
The y-intercept is the point where the line crosses the y axis and x= 0
the equation of a line is y= mx+b
m= slope
b= y intercept

Eight businesses were asked how many employees they have. Here is the data: 4, 5, 6, 5, 4, 6, 3, 8. Find the mean / A ocho empresas se les preguntó cuántos empleados tienen. Aquí están los datos: 4, 5, 6, 5, 4, 6, 3, 8. Encuentre la media * A.5 B.5.125 C.4 D.6
Answer:
B. 5.125
Step-by-step explanation:
When you add the numbers, you get 41. Then, you divide by how many numbers there are and you would get 5.125.
Answer:
B. 5.125
When you begin to add the numbers your total will be 41 but you would need to divide by the total amount of numbers in the data and your answer would be 5.125
When you add the numbers, you get 41. Then, you divide by how many numbers there are and you would get 5.125.
Step-by-step explanation:
Given the equation (x - 13) ^ 2 + y ^ 2 = 64 identify the center and radius
Answer:
radius is 8; center is at (13, 0).
Step-by-step explanation:
Compare the given (x - 13) ^ 2 + y ^ 2 = 64 to:
(x - h)^2 + (y - k)^2 = r^2. (h, k) represents the center
and r the radius.
Since 64 = r^2, r = the radius = 8 units = r
We also see that h = 13 and k = 0.
Thus, the center of the given circle is (13, 0).

1. Mr. Smith visited the park one sunny afternoon. He noticed that only
dogs and people were in the park that day. While he was resting on a park
bench, he observed that there were 15 heads and 50 legs in the park.
Which pair of system of equations can be used to determine the number
of dogs and the number of people in the park that day (use x = # of people;
y = # of dogs)?
x + y = 50: 2x + 4y = 15
x + y = 15, 4x + 2y = 50
X + y = 15:2x + 4y = 50
x + y = 50; 4x + 2y = 15
Answer:
x+y=15 ; 2x+4y=50
Step-by-step explanation:
Let x be the number of people
Let y be the number of dogs.
Equation regarding Total Heads:Total number of heads = 15
As
1 person has 1 head
1 dog has 1 head
Total no. of heads of people = 1 * x = x
Total number of heads of dogs = 1*y = y
Equation becomes:
x+y=15
Equation regarding Total Legs:Total number of legs = 50
As
1 person has 2 legs
1 dog has 4 legs
Total no. of legs of people = 2 * x = 2x
Total number of legs of dogs = 4*y = 4y
Equation becomes:
2x+4y=50

С

D
360°
need help please
Answer:
Not widely used. If you continue to increase an angle it will eventually 'double back' on itself and form a full 360° angle. This is the Full Angle. One could argue that this is the same as a zero-sized angle. But we generally mean the reflex angle and so it is a full circle or 360°. Adjust the angle above and try to create the full angle going around in both directions.

/ / * ANSWER PLS * / / MK and ML are tangent to circle J. If MK = 6x – 15 and ML = 2x + 9, find x.
Answer:
x=6
Step-by-step explanation:
As MK and ML are tangent to the circle, they are also congruent (MK = ML). Thus we can set the equation:
6x-15 = 2x+9
Now solve for x:
6x-2x = 9+15
4x=24
x=6
Answer:
B.
Step-by-step explanation:
MK and ML are tangents to a circle and " originating from the same point" so
MK=ML
Since MK = 6x-15 and ML = 2x+9
So,
6x-15 = 2x+9
6x-2x = 9+15
4x = 24
Dividing both sides by 4
So, we'll get
x = 6
The probability that a person has immunity to a particular disease is 0.6. Find the mean number who have
immunity in samples of size 12.
Answer:
Step-by-step explanation:
This is a binomial probability problem. There are only two outcomes. It is either a chosen person has immunity to a particular disease or he does not. The probability of success in this case, p is the probability that a chosen person has immunity to a particular disease. Thus
p = 0.6
The probability of failure, q is q = 1 - p
Thus, q = 1 - 0.6 = 0.4
Mean = np
Where n represents sample size. Thus,
Mean = 12 × 0.6 = 7.2

Prove that
[tex]x {}^{2} - 2[/tex]
will never be divisible by 3.
Answer:
Any integer x can be represent in form of 3k, 3k+1, or 3k + 2 (k is integer).
Case 1: x = 3k => x^2 - 2 = 9k^2 - 2, which will not be divisible by 3
(notice that 2 is not divisibble by 3, but 9k^2)
Case 2: x = 3k + 1 => x^2 - 2 = 9k^2 + 6k + 1 - 2 = 9k^2 + 6k - 1, which will not be divisible by 3
(notice that 1 is not divisibble by 3, but 9k^2 + 6k)
Case 3: x = 3k + 2 => x^2 - 2 = 9k^2 + 12k + 4 - 2 = 9k^2 + 12k - 2, which will not be divisible by 3
(notice that 2 is not divisibble by 3, but 9k^2 + 12k)
=> x^2 - 2 will never be divisible by 3

Denice had 236 yellow stars and 196 blue stars. She wants to arrange them in rows of 4. How many rows of stars would Denice have?
Answer:
108
Step-by-step explanation:
236 + 196 = 432 (total stars)
432 / 4 = 108 rows.
Answer:
108 rows.
Step-by-step explanation:
236 stars + 196 stars = 432 stars in total
So if you're putting 432 stars in 4 rows, you have to divide 432/4, which equals 108 rows with 4 stars in each row.
Hope this helped you :)

If p(x) is a quadratic function and p(-1) = p(7) = 2,

the vertex of the parabola formed when y = p(x) is
graphed in the xy-plane?
PLEASE EXPLAIN- I really don’t know:,)
(0,8)
(4,3)
(6,7)
(3,9)
Answer:
3,9
Step-by-step explanation:
hint: quadratic function
the form can be x² or x²+b or x²+bx+c
when p(-1)= 2 it means if we take x-axis = -1 the result (y-axis) will be 2. Same thing happen if we take x = 7
the vertex will always in the middle. So the middle of x = -1 and x = 7 is 3
-1, 0, 1, 2, 3, 4, 5, 6, 7
the vertex will occured when x = 3
the only answer with x = 3 is the fourth one (3,9)
