What is the solution to the system of equations?

Mathematics
1 answer:
Elan Coil [88]3 years ago
5 0

Answer:

(7, 10.5)

Step-by-step explanation:

just going to use substitution here.

so you would substitute the y value in the equation x-2y=-14 with 2x-3.5.

it should look like: x-2(2x-3.5)=-14

solve the equation and you get x=7.

plug in 7 for x in either equation and you get y= 10.5.

Answer:

x = 960

or, x = √576×√1600

or, x = 24×40

or, x = 960

Identify the type of function represented by f(x)=1/2(3)^x
Firlakuza [10]

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

The independent variable in the function f(c) = 2c + 9 is c whereas the dependent variable is f.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

If b > 1, it is an exponential growth but if b < 1, it is an exponential decay.

Given the function:

f(x) = (1/2)(3)ˣ

since 3 > 1, it is an exponential growth.

The function represented by f(x) = (1/2)(3)ˣ is an exponential growth
