Solve this system of equations: What is the value of x?

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

Substitute y=2x in the first equation into the second.

The second equation then becomes;

x = -(2x)+6

x = -2x+6

Collectiing like terms, more -2x to the left,

x+2x =6

3x=6

x= $\frac{6}{3}$

x= 2

B) Express 0.6363......as a rational number in its lowest term.

bulgar [2K]

Answer:

$\frac{7}{11}$

Step-by-step explanation:

We require 2 equations with the repeating digits (63) placed after the decimal point.

let x = 0.636363..... (1) multiply both sides by 100

100x = 63.6363... (2)

Subtract (1) from (2) thus eliminating the repeating digits

99x = 63 ( divide both sides by 99 )

x = $\frac{63}{99}$ = $\frac{7}{11}$ ← in simplest form

What is -15x=-240?????????

Vlad [161]

You divide -15 on both sides to keep the x alone
-240/ -15=16
A negative divided by a negative is a positive so x=16

Remember that an exponent means repeated multiplication.

The exponent of 4 means you have four $\big(b^2\big)$ 's mutiplied together:

$\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)$

And then each exponent of 2 inside means you have two $b$ 's multiplied inside each set of parentheses.:

$\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)$

There are 8 b's there when you expand this out.

A car tire is spinning a complete revolution every 0.60 seconds. The valve stem is 2 inches above ground at its lowest point and

finlep [7]

Answer:

Step-by-step explanation:

What is the amplitude, ||, of the height and co-height functions for this car tire

|| = 6

Let () represent the co-height function after rotation by radians, and let () represent the height function after rotation by radians. Write functions for the co-height and for the height in terms of .

() = ()

The co-height graphs are the same but translated 2 inches upward

so our function is:

() = () + 2 or

() = () + 2
