Solve the system by the elimination method.<br><br> 2a + 3b = 6<br> 5a + 2b - 4 = 0
mariarad [96]
2a + 3b = 6 --> Equation 1
5a + 2b = 4 --> Equation 2
Equation 1 * 5 --> 10a + 15b = 30
Equation 2 * 2 --> 10a + 4b = 8
Equation 1 - Equation 2 --> 11b = 22 --> b = 2
Sub b=2 in Equation 1 (or 2, either works):
2a + 3b = 6
2a + 3(2) = 6
2a + 6 = 6
2a = 0
a = 0

b = 2, a = 0

In Exercise,find the horizontal asymptote of the graph of the function.<br> f(x) = 25/1+4x
const2013 [10]

Answer:

Horizontal asymptote of the graph of the function f(x) = 25/1+4x is y=0

Step-by-step explanation:

I attached the graph of the function. Graphically it can be seen that the horizontal asymptote of the graph of the function is y=0. There is also a <em>vertical</em> asymptote at x=-1/4

When denominator's degree (1) is higher than nominator's degree (0) then the horizontal asymptote is y=0

What is the value of arcsin(0) in degrees?<br><br> Enter your answer in the box.
melisa1 [442]

Answer:

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.

Step-by-step explanation:

To Find:

arcsin(0) in degrees =?

Solution:

' arcsin ' a mathematical function that is the inverse of the sine function.

Therefore, arcsin (x) is called the inverse sine function.

It is the angle whose sine is the number x.

So here we require angle in degree for which the Sine is '0'.

It is also written as

\sin^{-1}x

We Know that

\sin 0\°=0\\or\\\sin 180\°=0

Therefore,

\arcsin (0) = 0\°\\or\\\arcsin (0) = 180\°

Also integer multiples of 180° will have

\arcsin (0)=n\times 180\°

Where n = integer

Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on

Therefore,

The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.

last month, a bookstore ran the following at and sold 85 calculators, generating $4,083 in sales. How many of each type of calcu
Scilla [17]

Answer:

31 scientific calculators

54 graphing calculators

Step-by-step explanation:

X = number of $15 calculators

Y = number of $67 calculators

X+Y = 85   then X = 85-Y

15X+67Y = 4083

substitute for X

15(85-Y)+67Y = 4083

1275 - 15Y + 67Y = 4083

reduce

52Y = 2808

Y = 54

X = 31
