Answer:
x<-11.25
Step-by-step explanation:
you treat it like its 12x-3=-138, your goal is to isolate the x. first you subtract the 3 from both sides (12x<-135) and then divide both sides by 12 giving you 11.25 on one side and x on the other.
Answer:
x < -45/4 or it can be written as ( -infinity, -45/4 )
Step-by-step explanation:
12x - 3 < -138
12x < -135
x < -45/4
or x < -11.25
Al vender una computadora, un vendedor descuenta el 15%, y aun así gana el 35%, del costo. ¿qué %del costo es el precio de venta?
Veremos que el precio de venta es el 158% del costo.
¿Que porcentaje del costo es el precio de venta?
Sabemos que con el descuento del 15%, el vendedor gana 35% del costo.
Es decir, si el costo es C, entonces el precio al que se vende la computadora es:
P' = (1 + 0.35)*C = 1.35*C
Pero, esto es con un 15% de descuento. Entonces si el precio de venta es P, tendremos:
P' = (1 - 0.15)*P = (0.85)*P
Reemplazando esto arriba tenemos:
(0.85)*P = 1.35*C
Resolviendo para P:
P = 1.35*C/0.85 = 1.58*C
Para obtener el porcentaje, multiplicamos el coeficiente por 100%.
1.58*100% = 158%.
Es decir, el precio de venta es el 158% del costo.

Select all the expressions that are equivalent to 4 ^ - 3
Answer:
B. 2^-6
C. 1/4³
D. (1/4) (1/4) (1/4)
Step-by-step explanation:
4^-3 is the same as 1/4³ so it is equivalent
46-3 = 1/64 so (1/4) (1/4) (1/4) is equivalent because it also equals 1/64
2^-6 is the same as 1/2^6 which equals 1/64 so it is also equivalent

8/15 as a decimal rounded to the nearest hundreth
Answer:
0.53
Step-by-step explanation:
A fraction bar can also mean division. So 8/15 the fraction also means 8÷15.
8÷15 = 0.5333333...
Rounding to the nearest hundredth means there should be only two numbers to the right of the decimal point.
8/15 ~= 0.53

Answer:
x=40 m∠A=100° m∠B=80° m∠C=65°
Step-by-step explanation:
Step 1: Find relationships between the angles (corresponding, alternate exterior, alternate interior, consecutive interior, or consecutive exterior)
Step 2: m∠A + m∠B = 180°
So, (3x-20)° + (2x)° = 180°
Step 3: Solve for x (x=40)
Step 4: Plug in x to the angles
m∠A= 3(40) - 20
m∠B= 2(40)
m∠C= 2(40)-15

What is the equation of a hyperbola with a = 8 and c = 20? Assume that the transverse axis is horizontal.
Answer:
[tex]\frac{x^{2} }{64} -\frac{y^{2} }{336} =1[/tex]
Step-by-step explanation:
The equation of hyperbola is given by:
[tex]\frac{x^{2} }{a^{2} } -\frac{y^{2} }{b^{2} }[/tex]
Where [tex]c^{2} =a^{2} +b^{2}[/tex]
∵ [tex]a=8,c=20[/tex]
∴ [tex]b^{2} =c^{2} -a^{2}[/tex]
⇒ [tex]b= \sqrt{20^{2} -8^{2} } =4\sqrt{21}[/tex]
Now, [tex]\frac{x^{2} }{a^{2} } -\frac{y^{2} }{b^{2} } =1[/tex]
⇒ [tex]\frac{x^{2} }{8^{2} } -\frac{y^{2} }{y(4\sqrt{21} )^{2} } =1[/tex]
⇒ [tex]\frac{x^{2} }{64} -\frac{y^{2} }{336} =1[/tex]
Hence, equation is [tex]\frac{x^{2} }{64} -\frac{y^{2} }{336} =1[/tex]

Which expression is equivalent to i 233?
1
–1
i
–i
Step-by-step explanation:
i¹ = i
i² = i×i = -1
i³ = -1 × i = -i
i⁴ = -i×i = - -1 = 1
i⁵ = 1×i = i
...
so, when the exponent of i modulo 4 (the remainder when dividing by 4) = 0, then the result is 1.
= 1, then the result is i
= 2, then the result is -1
= 3, then the result is -i
233 modulo 4 = 1 (233/4 = 58, remainder 1).
so, the result is i (the third answer option).

The cone has a height of 6 and a diameter of 3 inches. What is the volume?
Answer:
14.14
Step-by-step explanation:
We know that to calculate volume of a cone you must do π r^2*h/3
so we can divide the diameter by 2 to find the radius and just input the radius and height into the formula to get 14.14
A bag of apples weighs 6 2/7 pounds . A crate of bananas is 4 times as heavy as the apples. How much heavier are the bananas than the apples
Call the weight of the bag of apples as x (x = 6 2/7)
Since the crate of bananas is 4 times as heavy as the apples -> the crate of bananas = 4x
So, to find the weight difference, we minus those : 4x - x = 3x
Now we convert this : 3x = 3 x 6 2/7 = 132/7
Convert to :
Mixed : 18 6/7

Why do you replace y with 0 when finding the x-intercept of a graph?
Here’s what you need to know about intercepts. The x intercept of a graph has y coordinate zero. The y intercept of a graph has x coordinate zero.
AN EXAMPLE OF THIS IS:
So if you have a function y = 2x + 8 you would set x = 0 to find the y intercept. So we would get y = 8. To find the x intercept we would set y = 0 and get 0 = 2x + 8
or -8 = 2x or x = -4
Now if you have a more difficult like function y = 3x^2 + 10x - 4 we proceed the same way. To find the y intercept we would set x = 0 and get y = -4 so the y intercept is (0,-4)
To find the x intercept we would set y = 0 and get 3x^2 + 10x - 4 = 0. If you know the quadratic formula you could solve this by:
x = [-b +- SR(b^2 - 4*a*c] / 2a
so in our case x = [-10 +- SR(100 - 4*3*(-4))] / (2*3)
x = [-10 +- SR(100 + 48)] / 6
x = [-10 +- SR (148)] / 6
x = [-10 +- 12.2] / 6 approximately
x = [-10 - 12.2] / 6 or [-10 + 12.2 / 6]
x = -22.2/6 or 2.2/6

Factor the polynomials completely, then solve 48x² - 75 = 0
Answer:
[tex]x=\frac{5}{4} \text { or } x=-\frac{5}{4}[/tex]
Step-by-step explanation:
48 = 3 × 16
75 = 3 × 25
_________
Then, a Complete factorization of 48x² - 75 is :
[tex]\begin{aligned}48 x^{2}-75 &=3 \times\left(16 x^{2}\right)-3 \times(25) \\&=3 \times\left(16 x^{2}-25\right)\end{aligned}[/tex]
_____________________
Now let’s solve our equation 48x² - 75 = 0
48x² - 75 = 0 means 3 × (16x² − 25) = 0 means 16x² − 25 = 0
[tex]\begin{array}{l}16 x^{2}-25=0 \\\\\Leftrightarrow 16 x^{2}=25 \\\\\Leftrightarrow x^{2}=\frac{25}{16} \\\\\Leftrightarrow x=\sqrt{\frac{25}{16}} \text { or } x=-\sqrt{\frac{25}{16}} \\\\\Leftrightarrow x=\frac{5}{4} \text { or } x=-\frac{5}{4}\end{array}[/tex]

John Travolta flew his plane last weekend. What would be the angle measure of∠x when his plane reached an altitude of 2500m?
Answer:
67°
Step-by-step explanation:
Ignore the 2500m for now.
To find angle x, we know that the sum of the degrees in a triangle is 180. We see that under the 2500m there is a square, indicating that the angle is 90 degrees.
So we can do 180-23-90 = 67.
Therefore, the angle measure of ∠x is 67°
