Answer:
x = 8
Step-by-step explanation:
5(x-2)=30
Distribute
5x- 10 = 30
Add 10 to each side
5x-10+10 = 30+10
5x= 40
Divide by 5
5x/5=40/5
x = 8
Answer:
x=
Step-by-step explanation:
using distributive property, you multiply 5 by x and by 2, which gets you 5x and 10
5(x-2)=30
5x-10=30
5x=40
x=8
Write the equation of the line that passes through the points (3,5) and
(-5,0). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.
Answer:
5/8
Step-by-step explanation:
solution
x1,y1= 3 , 5
x2,y2= -5,0
slope= y2-y1÷x2-x1
what is the value of x?
Answer:
80
Step-by-step explanation:
The sum of the measures of the interior angles of a triangle is 180 degrees, so:
x+(x-15)+(x-45)=180
x+x-15+x-45=180
3x-60=180
3x=240
x=80

Let's add the following polynomials.
How to add them? Just combine like terms. :)
[tex]\bold{2x^2-10x+1 ~and~x^2+15x-8}[/tex]
[tex]\bold{2x^2+x^2-10x+15x+1-8}[/tex]
Hence, the answer is

b i your answer i know it
Step-by-step explanation:
The 3rd Box-and-Whisker Plot correctly depicts the data given.
What is a expression? What is a mathematical equation? What is a box and whisker plot?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. In descriptive statistics, a box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles.We have the Box-and-Whisker Plots for the data -
{22, 24, 24, 25, 26, 26, 27, 28, 28, 30} shown in the image.
We can identify the boxplot by the median calculation easily. We can find the median of the given data set as -
[M] = (26 + 26)/2 = (2 x 26)/2 = 26
Therefore, the 3rd Box-and-Whisker Plot correctly depicts the data given.

103/8-9/14*14/17 please help thx
Answer:
12.3455882353
Step-by-step explanation:
(103/8) = 12.875
(9/14) = 0.64285714285
0.64285714285 x 14 = 9
(9/17) = 0.5294117647
12.875 - 0.5294117647 = 12.3455882353

Please Help! locks in 30 min! Will give brainlest!
Answer:
Step-by-step explanation:
cos(2θ) - cosθ + 1 = 0
2cos²θ - 1 - cosθ + 1 = 0
2cos²θ - cosθ = 0
2cosθ(cosθ - 1/2) = 0
cosθ = 0, θ = π/2, 3π/2
cosθ = 1/2, θ = π/3. 5π/3

The first question I got 1056.25
Step-by-step explanation:
Consider a Poisson distribution with a mean of two occurrences per time period. a. Which of the following is the appropriate Poisson probability function for one time period? 1 2 3 - Select your answer - b. What is the expected number of occurrences in three time periods? c. Select the appropriate Poisson probability function to determine the probability of occurrences in three time periods. 1 2 3 - Select your answer - d. Compute the probability of two occurrences in one time period (to 4 decimals). e. Compute the probability of six occurrences in three time periods (to 4 decimals). f. Compute the probability of five occurrences in two time periods (to 4 decimals)
Answer:
F(k) = 2k e-2 / k!
Mean =µ = 2 x 3 = 6
f(k) = 6k e-6 / k!
F(2) = 22 e-2 / 2!
= 0.2707
F(6) = 66 e-6 / 6!
= 0.1606
f(5) = 45 e-4 / 5!
= 0.1563
Step-by-step explanation:
Solution:
Given:
Mean = µ = 2 per time period
Poisson probability:
F(k) = µk e-µ / k!
(a) Poisson probability for one time period.
Put µ = 2 in formula, we get:
F(k) = 2k e-2 / k!
(b) Expected number of occurrence in three time period.
Mean of one time period is multiply with number of time period.
Mean =µ = 2 x 3 = 6
(c) Probability of occurrence in three time period.
Put the value of µ = 6 in the given formula, we get:
f(k) = 6k e-6 / k!
(d) Probability of two occurrences in one time period.
Put k = 2 in given formula:
F(2) = 22 e-2 / 2!
= 0.2707
(e) Probability of six occurrences in three time period.
Put k = 6, in given formula, we get:
F(6) = 66 e-6 / 6!
= 0.1606
(f) Probability of five occurrences in two time period.
Mean of one time period is multiply by the number of time periods.
µ = 2 x 2 = 4
put k = 5 and µ = 4 in formula, we get:
f(5) = 45 e-4 / 5!
= 0.1563

What is the equation of the line that passes through the point (-6,-4) and has a slope of 1/3
Answer:
[tex]y=\frac{1}{3}x-2[/tex]
Step-by-step explanation:
Given the information, we can use the point-slope form to find the equation for the line: [tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-(-4)=\frac{1}{3}x(x-(-6) )[/tex]
Isolating y and combining like terms gives us [tex]y=\frac{1}{3}x-2[/tex]
Identify the quadratic function(s). (Select all that apply). y(y + 4) - y = 6 (3x + 2) + (6x - 1) = 0 4b(b) = 0 3a - 7 = 2(7a - 3)
Answer:
[A] y(y + 4) - y = 6
[C] 4 b (b)=0
Step-by-step explanation:
First let know what is a quadratic functions(s):
A function is called Quadratic if it consist of only one variable, maximum of three terms, and highest degree of the variable in that Polynomial is 2.
Now let's go through the answer choices:
[A]
y *(y+4) - y =6
y² + 4 y - y -6=0
y²+3 y -6=0
Thus, This is Quadratic Function.
[B]
3 x +2 + 6 x -1=0
9 x-1=0
Thus, This is not Quadratic Function
[C]
4 b*(b)=0
4 b²=0
Thus, This is Quadratic Function.
[D]
3 a- 7 =2 * (7 a-3)
3 a - 7=14 a - 6
3 a - 14 a = 7 -6
-11 a =1
Thus, This is not a Quadratic Function.
Hence, [A] and [C] are quadratic functions.

Algebraically, an ordered pair is a solution to a system of two linear inequalities if and only if it __________.
A.
makes both the top and bottom inequalities false
B.
makes the top inequality true and the bottom inequality false
C.
makes the top inequality false and the bottom inequality true
D.
makes both the top and bottom inequalities true
Answer:
D. Makes both the top and bottom inequalities true
Step-by-step explanation:
System of linear inequalities
Consider these two inequalities:
2x+3y > 20
3x-2y > 5
The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because
2*3+3*5=21 and it's effectively greater than 20.
But that pair makes the second inequality false, since
3*3-2*5=-1 is not greater than 5.
Thus, the pair (3,5) is not part of the solution.
If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.
Thus, the correct answer to the question is
D. Makes both the top and bottom inequalities true

find the rate of change from the equation y=-7/8x+3
Answer:
-7/8
Step-by-step explanation:
rate of change is the same as slope so -7/8
Answer:
-7/8Step-by-step explanation:
find the rate of change from the equation:
y = -7/8x + 3
use the formula: y = mx + b
where:
y = how far up the line goes
m = slope
x = how far along
b = Y-intercept
so the rate of change is the same as the slope
therefore, the slope = -7/8
