How do you solve the equation<br> x-2y-1=0<br> y-5x+14=0

Tcecarenko [31]

The solution is x= 3 and y = 1

Step-by-step explanation:

Given equations are:

$x-2y-1 = 0\ \ \ \ Eqn1\\y-5x+14 = 0\ \ \ \ Eqn2$

From equation 1:

$x = 2y+1$

Putting in equation 2:

$y - 5(2y+1)+14 = 0\\y-10y-5 +14 = 0\\-9y-5+14 = 0\\-9y+9 = 0\\-9y+9-9 = 0-9\\-9y = -9$

Dividing both sides by -9

$\frac{-9y}{-9} = \frac{-9}{-9}\\y = 1$

Putting y = 1 in equation 1:

$x - 2(1)-1 = 0\\x -2-1 = \\x-3 = 0\\x-3+3 = 0+3\\x = 3$

Hence,

The solution is x= 3 and y = 1

If f(x)=3x^2-1 and g(x)=x+2, find (f+g)(x)

algol13

Answer:
(f+g)(x) = 3x^2 + x + 1

Explanation:
We are given that:
f(x) = 3x^2 - 1
g(x) = x + 2
To find (f+g)(x), all we have to do is add the above to functions as follows:
(f+g)(x) = f(x) + g(x)
= 3x^2 - 1 + x + 2
= 3x^2 + x + 1

Hope this helps :)

Use the counting principle to determine the number of elements in the sample space. Two digits are selected without replacement

kicyunya [14]

Answer:

if the order of the digit matters, we have:

options: 1, 2, 3, 4.

We want to select two digits.

First selection: we have 4 options

Second selection: we have 3 options (because we already selected one in the first selection)

The total number of elements in the sample space, or the total number of combinations, is equal to the product of the number of options in each selection, this is:

P = 4*3 = 12

Given that √5 ≈ 2.2360679775 and ???? ≈ 3.1415926535, find the sum √5 + ???? to an accuracy of 10−8 without using a calculator.

muminat

Answer:

√5 + π = 537766063.1 × $10^{-8}$

Step-by-step explanation:

given data

√5 ≈ 2.2360679775

π ≈ 3.1415926535

to find out

√5 + π

solution

√5 + π = 2.2360679775 + 3.1415926535

√5 + π = 5.3776606310

√5 + π = 5.3776606310 × $\frac{10^{-8}}{10^{-8}}$

√5 + π = 537766063.1 × $10^{-8}$
