Is the function an exponential function?
y=(-2)^x
Answer:Yes
Step-by-step explanation:
the normal exponential function is ab^x, where a represent the growth( sometimes you don't need this part), b is average rate of growth and x is the number of times we exponate. [tex]-2^{x}[/tex] is a exponetital function because it includes the b and x part. The a part is someetimes used but not always.
A function is a relationship between inputs where each input is related to exactly one output.
An exponential function is a function in the form
y = [tex]a^{x}[/tex]
Where a = constant and x = variable.
y = [tex](-2)^{x}[/tex] is an exponential function.
Where -2 is a constant and x is a variable.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
y = [tex](-2)^{x}[/tex]
An exponential function is a function in the form
y = [tex]a^{x}[/tex]
Where a = constant and x = variable.
Example:
y = [tex]3^{x}[/tex]
y = [tex]5^{x}[/tex]
We see that,
y = [tex](-2)^{x}[/tex]
-2 is a constant
x is a variable
Thus,
y = [tex](-2)^{x}[/tex] is an exponential function.
Where -2 is a constant and x is a variable.

Answer:
x = 5, x = -7
Step-by-step explanation:
If you mean find the roots, then x = 5 and x = -7
Because roots makes the equation equal to 0 and 5 - 5 = 0 and -7 + 7 = 0

-6y + 2 = -4x
y – 2 = x
Answer:
x=-5 and y=-3
Step-by-step explanation:
-6y+2=-4x convert this into standard form
y=x+2
plug in the slope intercept form in to y
-6(x+2)+4x=-2
-6x-12+4x=-2
-2x-12=-2 now solve for x
-2x-12+12=-2+12
-2x=+10
x=-5 now solve for y
y=-5+2
y=-3
so basically x=-5 and y=-3

Answer:
Area of rectangle = [tex]\mathbf{x^2-4x}[/tex]
Perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]
Step-by-step explanation:
We are given:
Length of rectangle = x
Width of rectangle = x-4
We are not given if we want to find area of rectangle or perimeter of rectangle.
So, I will be finding both
Area of rectangle
The formula used is: [tex]Area\: of\: rectangle=Length \times Width[/tex]
Putting values and finding area
[tex]Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x[/tex]
So, we get area of rectangle = [tex]\mathbf{x^2-4x}[/tex]
Perimeter of rectangle
The formula used is: [tex]Perimeter \: of\: rectangle=2(Length+ Width)[/tex]
Putting values and finding perimeter
[tex]Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8[/tex]
So, we get perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

PLEASE HELP!!!!!! what is the purpose of arithmetic and geometric sequences?
Answer:
An arithmetic sequence has a constant difference between each term. ... A geometric sequence has a constant ratio (multiplier) between each term. An example is: 2,4,8,16,32,… So to find the next term in the sequence we would multiply the previous term by 2.

Answer:
23a) x=-y+9/2
23b) x=1/2 y+3/2
Step-by-step explanation:
23a:
Let's solve for x.
2x+2y=9
Step 1: Add -2y to both sides.
2x+2y+−2y=9+−2y
2x=−2y+9
Step 2: Divide both sides by 2.
2x/2 = -2y+9/2
x = -y+9/2
23b:
Let's solve for x.
2x−y=3
Step 1: Add y to both sides.
2x−y+y=3+y
2x=y+3
Step 2: Divide both sides by 2.
2x/2=y+3/2
x = 1/2 y+3/2

I need to find the missing angle thank you
Answer:
The missing angles measure is 70 degrees
Step-by-step explanation:
First we must complete the left triangles last measure:
60+65+x=180
x=55
Then we have to make all of those three middle angles equal 180:
55+50+y=180
105+y=180
y=75
Now we add 75 to 35 to the missing angle to get 180:
75+35+z=180
110+z=180
z=70
The missing angles measure is 70 degrees

What is the answer??
Answer:
13.14
Step-by-step explanation:
First you would solve what is in the parentheses.
0.9 - 0.14 = .76
After that you would solve the exponent
3^2 = 9
Now the equation should look like: 9 · 0.76 + 6.3
Multiply 9 and 0.76 to get: 6.84
6.84 + 6.3 = 13.14

Tessa likes to carve bird and cat figures out of wood. She has carved 4 times as many bird figures as cat figures. If Tessa has carved 24 bird figures, how many figures has she carved altogether?
Tessa carved a total of 30 figures including bird and cat figures.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
let, The number of cat figures is 'x'.
Given, She has carved 4 times as many bird figures as cat figures.
Therefore, 4x = 24.
x = 24/4.
x = 6.
So, Tesaa carved 6 cat figures and hence she carved a total of

what is the length of side c if side A is 7 and side b is 9 and angle c is 79
Answer:
C is approximately 10.3
Step-by-step explanation:
To get the length of c, we use the cosine rule
This is;
The square of the missing side is equal the sum of the squares of the other sides minus 2 multiplied by the product of the two other sides and the cos of the angle facing the missing side
We have this as;
c^2 = 7^2 + 9^2 - 2(7)(9) * Cos 79
c^2 = 49 + 81 - 126 cos 79
c^2 = 130 - 24.042
c^2 = 105.96
c = √105.96
c = 10.29 which is approximately 10.3
