-5x + 11 = -8(4 + 6x) What are the steps?
Answer:
[tex]x = - 1[/tex]
Step-by-step explanation:
[tex] - 5x + 11 = - 8(6x + 4)[/tex]
[tex] = > - 5x + 11 = - 48x - 32[/tex]
Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.
[tex] = > 48x - 5x = - 32 - 11[/tex]
[tex] = > 43x = - 43[/tex]
Lets divide 43 on both the sides.
[tex] = > \frac{43x}{43} = \frac{ - 43}{43} [/tex]
[tex] = > x = - 1[/tex]
Circle O has a radius of 5 centimeters and central angle AOB with a measure of 60°. Describe in complete sentences how to find the length, in terms of a radian measure, of AB.
Answer:
We can use the formula for finding arc length given ccx central angle and radius.(insert formula below) We then substitute 5 in for r and and 60 for x. We multiply 2 pi times 5 which gives us 10. We then reduce the fraction of 60/360 to 1/6. We multiply 10 pi by 1/6 and that gives us
10 pi/6 or 5 pi/3
Step-by-step explanation:
We can use the formula
[tex]2\pi \times r( \frac{x}{360} )[/tex]
to find the arc length where r is the radius.
and x is the arc measure.
Plug it in for the numbers
[tex]2\pi \times 5( \frac{60}{360} )[/tex]
Multiply 2 pi times 5=10 pi
[tex]10\pi( \frac{60}{360} )[/tex]
Simplify 60/360 to 1/6
[tex]10\pi \times \frac{1}{6} = \frac{10\pi}{6} [/tex]
Reduce it to
[tex] \frac{5\pi}{3} [/tex]

Write a reclusive rule for the sequence, then give the next two numbers in the sequence 6,1,7,8,15,23
Answer:
aₙ = aₙ₋₁ + aₙ₋₂
where:
a₁ = 6
a₂= 1.
Step-by-step explanation:
We have the sequence:
6, 1, 7, 8, 15, 23, ...
Is easy to see that this sequence works as follows:
You take 2 consecutive numbers, and the next number is the sum of these two.
Then we have:
6 + 1 = 7
1 + 7 = 8
7 + 8 = 15
8 + 15 = 23
Then the n-th term is equal to the sum of the (n - 1) term and the (n - 2) term.
This is written as:
aₙ = aₙ₋₁ + aₙ₋₂
Because in the recursive rule needs two previous terms, we need to specify the two first terms of the sequence.
Then we need to write also:
a₁ = 6
a₂= 1.

Given:
The graph of a quadratic function [tex]y=x^2-4x+3[/tex].
To find:
(a) The coordinates of the turning point.
(b) The roots of the equation [tex]y=x^2-4x+3[/tex]
Solution:
(a)
From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.
The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.
Therefore, the coordinates of the turning point are (2,-1).
(b)
The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.
From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.
Therefore, the roots of the given equation are 1 and 3.

Which of following is an example of a quadratic inequality?
Answer:
B
Step-by-step explanation:
Quadratic inequalities are inequalities involving quadratics.
A is not an inequality.
B is an inequality and we can rewrite B as:
[tex]x^2+x<0[/tex]
So, B is a quadratic inequality, and is the answer.
C is not a quadratic. The x terms are not squared.
Likewise, D is not a quadratic either since no x terms are being squared.
Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?
A 2
B 6
C 8
D 10
Answer:
6 miles.
Step-by-step explanation:
To solve this problem, lets make an equation in slope-intercept form (y = mx + b)
The initial fee is $6. This is our y-intercept (b) as it is unchanging.
Our slope (m) would be $3, as it changes value per mile, which will be represented by x.
$24 was the total fare, so this is our y.
We have:
24 = 3x + 6
Subtract 6 from both sides.
24 - 6 = 3x + 6 - 6
We get:
18 = 3x
Divide by 3 on both sides.
18/3 = 3x/3
We get:
6 = x
So, Mike traveled 6 miles.

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.
A. c(p) = p + 0.42
B. c(p) = 42p
C. c(p) = p/0.42
D. c(p) = 0.42p
Answer:
D. c(p) = 0.42p
Step-by-step explanation:
total cost = .42(P)
Example: 5 lbs
$2.10 = $.42(5)
c(p) = 0.42p <== ur function
Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:
c(p) = 0.42p
Where: c(p) = total cost of sugar bought
p = pounds of sugar
c(p) is a function of p, because c(p) depends on p.
Answer: The function rule that gives the total cost is given by
Step-by-step explanation:
Let the number of pounds of sugar be 'p'.
Let the total cost would be C(p).
Cost of each pound = $0.42
So, the function rule would be
Hence, the function rule that gives the total cost is given by

Sports of the 25 baseball players on the baltimore orioles 2005 roster, 17 threw right handed, 12 were over 30 years old, and 9 both threw right handed and were over 30 years old. How many players on the team neither threw right handed nor were over 30 years old?
Answer: 5
Step-by-step explanation:
Let R be the event that players threw right-handed.
Let O be the event that players were over 30 years old.
Given: Total players = 25
n(R) = 17 , n(O) = 12 , n(R and O)=9
According to the probability formula,
n(R or O) = n(R)+n(O)-n(R and O)
⇒ n(R or O) =17+12-9
⇒ n(R or O) = 20
Now , n(neither R nor O) = Total - n(R or O)
= 25-20
=5
Hence, the number of players on the team neither threw right-handed nor were over 30 years old = 5

-9 - 12
-12 - 9
12 - (-9)
Answer:
Answer is - 9 + 12 because they have different signs in front of each integer. (if that is what the question means)
Step-by-step explanation:
Negative sign x negative sign = positive sign
-9 - (-12) = -9 + 12
-9 - 12
-12 - 9 = -9 - 12
12 - (-9) = 12 + 9 = 9 + 12
