Answer:
x = 1
Step-by-step explanation:
6x + 6x - 7 = 5
combine like terms
12x - 7 = 5
add 7 to both sides of the equation
12x - 7 + 7 = 5 + 7
12x = 12
divide both sides of the equation by 12
12x/12 = 12/12
x = 1

1 Two functions are shown below. Function A Function B x 0 3 5 y 5 3x 1 2 y 3 9 13 Which statement correctly describes the rates of change of the two functions? A The rate of change is 2 for both Function A and Function B. B The rate of change is 3 for both Function A and Function B. C The rate of change is greater for Function A than for Function B. D The rate of change is greater for Function B than for Function A.
Answers
Answer:
D The rate of change is greater for Function B than for Function A
Step-by-step explanation:
A function shows the relationship between a dependent variable and an independent variable. A linear function is given as y = mx + b, where m is the rate of change, y is the dependent variable, x is the independent variable and b is the value of y when x = 0.
Function B is given by y = 3x + 2. Comparing with y =mx + b gives m = 3. Therefore the rate of change of function B is 3.
Function A has x: 0, 3, 9 and y:3, 9, 13. Using the points (0,3) and (3, 9), we an get the equation of the function. The formula is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{9-3}{3-0}(x-0)\\ \\y-3=2x\\\\y=2x+3[/tex]
Function A is given by y = 2x + 3. Comparing with y =mx + b gives m = 2. Therefore the rate of change of function A is 2.
The rate of change is greater for Function B than for Function A
F&J Farms sells super egg-laying chickens that historically weigh on average 3 pounds with a standard deviation of 0.4 pounds. However, it has been discovered that the chickens actually weigh twice as much as they used to. What is actual the mean and standard deviation of the chickens?
Answers
Answer:
Mean of chicken = 6 pounds, Standard Deviation of chicken = 0.6 pounds
Step-by-step explanation:
Given : Chickens mean & standard deviation = 3 & 0.4 pounds respectively. Chickens considered weigh twice actually now.
If all numbers in the series are multiplied by a constant, the mean gets multiplied by that constant. So, new mean = 3 x 2 = 6
If all numbers in the series are multiplied by a constant, the standard deviation gets multiplied by that constant. So, new standard deviation = 0.4 x 2 = 0.8

solution for 3/4x - 12 = -18?
Answers
Answer:
x = -8
Step-by-step explanation:
Add 12 on both sides
You get 3/4x = -6
Multiply 4/3 on both sides
You get x = -24/3
Simplify and you get -8.
Answer:
x=-8
Step-by-step explanation:
The reason why x is -8 is because
The first step is to isolate the x
To isolate the x you got to add 12 to both sides
[tex]\frac{3}{4}[/tex]x-12+12=-18+12
the -12 gets canceled out by the positive twelve so all thats left now is
[tex]\frac{3}{4}[/tex]x=-18+12,-18+12 is -6 so its [tex]\frac{3}{4}[/tex]x=-6
The second step is to divide
now you have to divide by [tex]\frac{3}{4}[/tex] on both sides
[tex]\frac{\frac{3}{4} x}{\frac{3}4} } =\frac{-6}{\frac{3}{4} }[/tex]
which [tex]\frac{3}{4}[/tex] is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8

What is the increasing and decreasing intervals of this graph?
Answers
Answer:
A function is increasing on an interval if its slope is positive on that interval. That is, if you follow it to the right, it'll go up.
The graph increases at 3 and decreases at 1
A function is decreasing on an interval if its slope is negative on that interval. That is, if you follow it to the right, it'll go down.
Step-by-step explanation:
hope this helped
The function is increasing at (1, 0) and decreasing at (3, 0).
Given is a graph we need to determine what is the increasing and decreasing intervals of this graph,
If a function's slope is positive on an interval, the function is increasing on that interval. That is, it will go up if you follow it to the right.
The graph goes up at 3 and down at 1.
If a function's slope is negative on an interval, the function is declining on that interval. That is, it will descend if you follow it to the right.
Hence the function is increasing at (1, 0) and decreasing at (3, 0).
