Answer:
x = 48
Step-by-step explanation:
equation:
180 - x = 132
subtract 180 from each side:
180 - 180 - x = 132 - 180
-x = -48
divide both sides by -1:
[tex]\frac{-x}{-1} = \frac{-48}{-1}[/tex]
x = 48
to check, substitute 48 for x:
180 - x = 132
180 - 48 = 132
132 = 132

write an equation with slope of negative 2 for (3, -4)
Answer:
y = - 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = - 6 + c ⇒ c = - 4 + 6 = 2
y = - 2x + 2 ← equation of line

Solve the inequality. (Enter your answer using interval notation.)
x^2 ≤ 81
Answer
the answer is -9≤x≤9
Answer:
x = (-9,9)
Step-by-step explanation:
|x |< 9 - seperate the inequality into 2 possible cases
1. x<9, x>0 -x<9, x<0
find the intersection
x = (0,9) -x<9, x<0
find the intersection again
x = (0,9) x = (-9,0)
find the union
x = (-9,9)

Step-by-step explanation:
f(x) = 1 - x²
g(x) = [tex]\sqrt{11-4x}[/tex]
[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]
[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]
[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]
= [tex]\frac{1-1}{\sqrt{15}}[/tex]
= 0
(g + f)(x) = g(x) + f(x)
= [tex]\sqrt{11-4x}+1-x^2[/tex]
(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]
= [tex]\sqrt{3}-3[/tex]
(g - f)(x) = g(x) - f(x)
= [tex]\sqrt{11-4x}-(1-x^2)[/tex]
= [tex]\sqrt{11-4x}-1+x^2[/tex]
(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]
= [tex]\sqrt{15}[/tex]
(g . f)(x) = g(x) × f(x)
= [tex](\sqrt{11-4x})(1-x^2)[/tex]
(g . f)(2) = [tex](\sqrt{11-4(2)})(1-(2)^2)[/tex]

What is the arc length of the partial circle?
Answer:
pi/2
Step-by-step explanation:
The arc length is based on the circumference
c = 2 * pi *r
C = 2 * pi *1 = 2pi
This is 1/4 of the circle so the arc length given is 1/4 of the arc length
arc length = 1/4 ( 2pi)
= pi /2

This graph represents a linear function.
Enter an equation in the form y = mx + b that represents the function described by the graph.
Answer:
y=2x-2
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the line y=mx+b we need two points. I choose (0,-2) and (1,0)
Since y=mx+b where m=slope and b=y intercept (value of y when x=0)
We have the point (0,-2) so we know b=-2
Now we find the slope which is defined as
m=(y2-y1)/(x2-x1), in this case
m=(0-(-2))/(1-0)
m=2, so the line is
y=2x-2
cuatro amigos compraron una pizza:leo se comio 1/2 adan 1/4,joel 1/8 evelio se comio la que sobro.dibuja la pizza.dividela como se la repartieron y contesta las preguntas
a) quien comio mas?
b) quienes comieron menos?
c)quienes comieron igual?
d)cuantas pizzas se comieron en total?
Answer:
A) Leo comió más, ya que comió 1/2 de la pizza.
B) Joel y Evelio comieron menos, ya que comieron 1/8 de la pizza.
C) Asimismo, Joel y Evelio comieron igual, ya que cada uno comió 1/8 de la pizza.
D) En total, entre todos comieron una pizza.
Step-by-step explanation:
Dado que cuatro amigos compraron una pizza, de la cual Leo se comió 1/2, Adán 1/4, Joel 1/8 y Evelio se comió lo que sobró, para determinar quién comió más, quién comió menos, quiénes comieron igual y cuántas pizzas se comieron en total se deben realizar los siguientes cálculos:
1/2 + 1/4 + 1/8 + X = 1
4/8 + 2/8 + 1/8 + X = 1
7/8 + X = 1
X = 1 - 7/8
X = 1/8

In what time a certain sum of money will be 2.5 times at 10% rate of interest
Answer:
Step-by-step explanation:
It takes 15 years to get 2.5 times the sum at 10% p.a.
Let the principal be 'P'.
Let the amount be '2.5P'
Rate = 10%
Amount = Principal - Interest
2.5 P = P - Interest
Interest = 1.5 P
So, we get that
[tex]1.5P =\frac{P*R*T}{100} \\1.5 * 100 = 10 * T\\T = 15 years[/tex]

Quick question, did you find the answer?
You and your friend go to an amusement park. You buy t tickets and spend $8 on food.Your friend buys t tickets and spends $12 on food. Is it possible that you and your friend spent the same amount at the amusement park.
Answer:
In the case of 4 tickets it can be possible
Step-by-step explanation:
Let us assume the number of tickets be t
Now as per the question the equations would be
For you = t + $8
For your friend = t + $12
In the case when you both spend the same amount so the above equations would be equivalent to each other
t + $8 = t + $12
So here the tickets would be 4 so this is possible that you both spend the same amounts

Answer:
Step-by-step explanation:
y=mx+b where m=slope and b=y intercept
m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)
m=(12-0)/(4-0)=12/4=3
y=3x+b, using point (4,12) we can solve for b
12=3(4)+b
12=12+b
b=0 so the line is
y=3x
