solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

Step-by-step explanation:

We need to solve the equation: $-2(x + 3y) = 18$

Solving the equation:

$-2(x + 3y) = 18\\-2x-6y=18$

Simplifying and finding value of x:

$-2x-6y=18\\-2x=18+6y\\-2x/-2=18/-2+6y/-2\\x=-9-3y$

We can simplify and find value of y as well:

$-2x-6y=18\\-6y=18+2x\\-6y/-6=18/-6+2x/-6\\y=-3-1/3x$

So, solving equation in terms of x we get $x=-9-3y$

solving equation in terms of y we get $y=-3-1/3x$

<h3>What is the exponent or power?</h3>

The exponent or power of a number represent the multiplication of the that number to the power times.

Let suppose a number 2 has the power 2. Then it will be equal to,

$2^2=2\times2$

Similarly, 3 times of number 2 equal to the number 2 with exponent 3.

$2\times2\times2=2^3$

The expression is m times, m times, m times, m times, m. It can be written as,

$m\times m\times m\times m\times m\\$

The number m is total 5 time multiply by itself. Thus, the exponential form of the above equation is,

Find the equation of the exponential function represented by the table below:

Elden [556K]

Answer:

The equation of the exponential function represented by the table will be:

$f(x)= 2(4)^{x}$

Step-by-step explanation:

We know the equation of exponential function such as

$f(x) = ab^{x}$

Put x=0, and y=2 in the function

$2 = ab^{0}$

$2 = a$

Also x=1, and y=8 in the function

$8 = 2b^{1}$

$b=4$

Thus,

$f(x) = ab^{x}$

$= 2(4)^{x}$

Therefore, the equation of the exponential function represented by the table will be:

$f(x)= 2(4)^{x}$

Divide 100 in a ratio of 5:3

bixtya [17]

Answer:

62.5 : 37.5

Step-by-step explanation:

When we divide 100 into 5:3 ratio the parts we make need to add up to 100

5parts +3 parts = 8 parts

100/8 parts = 12.5 are in each part

12.5*5 : 12.5*3

62.5 : 37.5

check our answer 62.5+37.5 = 100 ✅
