Can somebody please help me with this.!
Answer:
1260
Step-by-step explanation:
First you will need to find the amount of sides of the polygon:
(After looking it is 9)
Each angle of the side of a nonagon is 140 degrees.
Multiply by 9 since you can make 9 triangles:
140 x 9 = 1260
Find the inverse of the function f(x) = 2x - 4.
Answer:
f⁻¹(x) = 1/2 x + 2
Step-by-step explanation:
f(x) = 2x - 4 y=2x - 4
swap x and y: x = 2y - 4
solve y: 2y = x + 4
y = 1/2 x + 2
Inverse notation: f⁻¹(x) = 1/2 x + 2
(-3, 11) a solution to the systems of equations: x – 3y = -36 and 3x + 4y = 48
true or false
Answer:
TRUE and FALSE (please look at step-by-step)
Step-by-step explanation:
How to know if it's true or false, you just simply plug in the given numbers to the x and y values.
x = -3
y = 11
for the x - 3y = -36 equation:
-3 -3(11) = -36
-3 - 33 = -36
This equation is true.
for the 3x + 4y = 48 equation:
3(-3) + 4(11) = 48
-9 + 44 = 35
This equation is false.

Therefore B. 10 ounces of hot Cheetos for $2.70
Find the value of x.
Answer:
110 degrees
Step-by-step explanation:
The sum of all the interior angles of a polygon is always equal to 180(n-2) where n is the number of sides. In this figure, there are 7 sides. This means that the sum of all the interior angles is 180(7-2) = 180 * 5 = 900.
Now, add up all the angles that you know and subtract that from 900 to find the value of x.
900 - (105 + 150 + 140 + 135 + 125 + 135) = 900 - 790 = 110 degrees

Taylor purchased 9 pints of ice cream for a party. If each guest will be served exactly 1 2 2 1 pint of ice cream, how many guests can Taylor serve?
Complete question :
Carly purchased 9 1/2 pints of ice cream for a party. If each guest will be served exactly 3/5 pint of ice cream, what is the greatest number of gusts that Carly can serve
Answer:
15 guests
Step-by-step explanation:
Given that:
Total pints of icecream = 9 1/2
Fraction of ice cream pints per guest = 3/5 pints
Number of guest that can be served :
Total pints / fraction per guest
9 1/2 ÷ 3/5
19/2 * 5/3
95 / 6
= 15.8 guest
Hence, greatest Number of guest that can be served = 15

Some number was divided into 42. This quotient was then multiplied by 8,after which the resulting product was added to 10. Given this sum totalled to 34,find the initial number.
Answer:
126
Step-by-step explanation:
In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.
(((x / 42) * 8) + 10) = 34 ... subtract 10 from both sides
((x / 42) * 8) = 24 ... divide both sides by 8
(x / 42) = 3 ... multiply both sides by 42
x = 126
Finally, we can see that the initial value was 126

Which value of x is a solution of the inequality 25x - 100 < 250?
Answer:
inequality form: x<14
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
The solution of the given inequality is set of all x such that x < 14.
What are Inequalities?Two or more expressions connected with symbols of inequality like ≥, ≤, > and < is called the inequalities.
There are different kinds of inequalities like polynomial inequalities which includes linear inequalities and quadratic inequalities, rational inequality and so on.
Linear inequalities will have the highest degree of the variable equals 1.
Given a linear inequality,
25x - 100 < 250
Adding both sides of the inequality with 100,
25x - 100 + 100 < 250 + 100
25x < 350
Dividing both sides of the inequality by 25,
25x / 25 < 350 / 25
x < 14
Hence the value of x in the inequality is all the values of x which are less than, < 14.

Line segment AB is divided by point C in the ratio 1:2. Point A is at (-6, 6) and point C is at (2, 4). What are the coordinates of point B?
9514 1404 393
Answer:
B(10, 2)
Step-by-step explanation:
The division by point C means ...
B -C = 2(C -A)
B = 3C -2A . . . . . add C and simplify
B = 3(2, 4) -2(-6, 6) = (3·2 -2(-6), 3·4 -2(6)) . . . . fill in the coordinate values
B = (6+12, 12-12)
B = (18, 0)
