Solve (1/81)^x = 243^x-9
Answer:
x=5
Step-by-step explanation:
(1/81)^x=(243)^x-9
(1/3^4)=3^5(x-9)
3^-4x=3^5(x-9)
-4x=5(x-9)
-4x=5x-45
-4x-5x=-45
-9x=-45
x=5

Find the value of x and y. WILL MARK BRAINLIEST
Answer:
x=7
y = 4
Step-by-step explanation:
Since it is a parallelogram
2x-2 =12
and 2y =8
2x-2=12
Add 2 to each side
2x-2+2 =12+2
2x = 14
Divide by 2
2x/2 =14/2
x = 7
2y =8
Divide by 2
2y/2 =8/2
y =4
Answer:
x = 7
y = 4
Step-by-step explanation:
To find the values of x and y, you need to set them equal to its congruent pair. On the parallelogram, you can see that there are two pairs of sides that are the same length, so set them equal to one another, like so:
2x - 2 = 12
Add 2 to both sides:
2x = 14
Divide 2 by both sides:
x = 7
Solving for y:
2y = 8
Divide both sides by 2:
y = 4

Which function can be used to model the graphed geometric sequence?
f(x + 1) = Five-sixthsf(x)
f(x + 1) = Six-fifthsf(x)
f(x + 1) = Five-sixths Superscript f (x)
f(x + 1) = Six-Fifths Superscript f (x)
Answer:
f(x+1)=(5/6)f(x)on: Five-sixths Superscript f (x)
EXPLANATION:
The defining characteristic of a geometric sequence is that each term is a constant multiple of the previous term, called the common ratio denoted r in the rules for geometric equations.
625/750=750/900=etc=r=5/6
The function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).
What is the general equation of a Straight line? What is a Geometric sequence?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
A geometric sequence is a sequence such that -
a(n + 1)/a(n) = K {constant}
[K] is called common ratio.
Given is a graph representing a geometric sequence.
Now, for -
f(2) = 1080
and
f(1) = 1296
So -
f(2)/f(1) = 1080/1296 = 5/6
In general -
f(x + 1)/f(x) = 5/6
f(x + 1) = 5/6 f(x)
Therefore, the function that can be used to model the graphed geometric sequence is f(x + 1) = 5/6 f(x).

Gideon asked 50 students at his middle school which option they would like for lunch: pizza, sandwiches or burritos. Ten students said pizza, 4 said sandwiches and the remaining students answered burritos. What percent of students in the school would you predict would choose burritos based on this survey?
Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36
and then you would take that number and divide it by 50: 36/50=.72
turn that into a percent and you'd get 72%

Answer:
211°
Step-by-step explanation:
Since m∠ADB is 149°, that also makes arc AB 149°. So to find out the measure of arc AEB, all you need to do is subtract 149 from 360:
360 - 149 = 211

Step-by-step explanation:
6)Let the number be x
Product of a number and -4 = x * -4 = -4x
Product of a number and -4 increase by 3 : -4x + 3
-4x +3 = 9
Subtract 3 from both sides
-4x + 3 - 3 = 9 - 3
-4x = 6
Divide both sides by (-4)
-4x/-4 = 6/-4
x = -3/2
x = -1 1/2
7)Let the number be x
[tex]\frac{x}{6}-9=11\\\\[/tex]
Add 9 to both sides
[tex]\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\[/tex]
Multiply both sides with 6
[tex]\frac{x}{6}*6=20*6\\\\[/tex]
x = 120

The height of a fireworks rocket launched from a platform can be approximated by h=-5t+ 30t +35, where h is the height in meters and t is the time in seconds. Find the time it takes the rocket to reach the ground after it is launched.
Answer:
Step-by-step explanation:
h=-5t+ 30t +35, where h is the height in meters and t is the time in seconds.
Considering the fact that the launched Rocket will hit the ground, it implies that the height will be zero. Hence the equation will be .
0 =-5t+ 30t +35
-5t+30t = -35
25t = -35
To find t, divide both sides by 25
25t/25 = -35/25
t = - 7/5
t = -1.4secs
Hence the time for the launched rocket to hit the ground will be -1.4secs

B.(-3,0). D(3-6)
C.(20.3). D(3, 0)
D. (-1.5, 3), 011.5, 0)
Answer:
itsc c (0,3) ,d(3,0)
Step-by-step explanation:
If AB is divided into three equal parts then coordinates of C is (0, 3) and D coordinates are (3, 0)
What is Coordinate Geometry?A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
Divide AB into three equal parts
[tex]X_{c}-X_{a}=\frac{1}{3} (X_{B}-X_{D})[/tex]
=3
[tex]Y_{a}-Y_{c}=\frac{1}{3} (Y_{A}-Y_{B})[/tex]
=3
So C is (0, 3)
[tex]X_{B} -X_{D} =\frac{1}{3} \times 9[/tex]
=3
[tex]Y_{D} -Y_{B} =\frac{1}{3} \times 9[/tex]
=3
So D coordinates are (3, 0)
Hence, if AB is divided into three equal parts then coordinates of C is (0, 3) and D coordinates are (3, 0)

You are walking directly away from your house. You are 5 miles away from your house when you start walking, so you can determine your distance from your house by adding 5 to the number of miles you have walked. In the equation below, x represents the number of miles you have walked, and y represents your distance from home in miles. The relationship between these two variables can be expressed by the following equation: y = x + 5. Identify the dependent and independent variables. *
Answer:
The independent variable is the number of miles you walked.
Unfortunately, I do not know the dependant variable.
Step-by-step explanation:
Dependent variable is distance from home (y)
Independent variable is number of miles walk (x)
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
According to questions,
x represents the number of miles have walked
y represents distance from home in miles.
The relationship between these two variables can be expressed by the following equation: y=x+5
The dependent variable is that whose value changes whenever the value of the independent variable is changed.
From the equation above:
When x=2, y=2+5=7 miles
When x=4, y=4+5=9 miles
We can clearly see that y changes for different values of x.
Hence, dependent variable is distance from home (y)
Independent variable is number of miles walk (x)
