Novay_Z [31]

Answer:

y=3x-5

Step-by-step explanation:

step 1

Find the slope of the given line

we have

(-3,2) and (0,1)

The slope m is

m=(1-2)/(0+3)=-1/3

step 2

Find the slope of the line perpendicular to the given line

Remember that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of its slopes is -1)

so

The slope is

m=3

step 3

Find the equation of the line in point slope form

we have

m=3

point(3,4)

y-4=3(x-3) ----> equation in point slope form

Convert to slope intercept form

y=3x-9+4

y=3x-5

Let f(x)=e^x and G(x)=x+6. What are the domain and range of g(f(x))?
Lena [83]

Answer:

Domain and Range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively

Step-by-step explanation:

We have the functions, f(x) = eˣ and g(x) = x+6

So, their composition will be g(f(x)).

Then, g(f(x)) = g(eˣ) = eˣ+6

Thus, g(f(x)) = eˣ+6.

Since the domain and range of f(x) = eˣ are all real numbers and positive real numbers respectively.

Moreover, the function g(f(x)) = eˣ+6 is the function f(x) translated up by 6 units.

Hence, the domain and range of g(f(x)) are 'All real numbers' and {y | y>6 } respectively.

Marlina received her salary on Friday. She spent one-half of her salary on rent and then spent $338 on her electric and water bi
Alenkinab [10]

Answer:

$654

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent 1/2 of her salary on rent and then $338 on her electric and water bill. So, after this, she will have:

x-\frac{1}{2}x-338

Left of her salary.

Next, she spent one half of what was left. So, it will be one-half of the equation. Therefore, she will have spent:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)

Finally, she spent $56 for gas. So, we will subtract 56:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56

And we know that after all of the expenses, she will have $102 left. Therefore:

x-\frac{1}{2}x-338-\frac{1}{2}(x-\frac{1}{2}x-338)-56=102

We want to know how much Marlina spent on rent. So, let's find her salary x first.

First, let's distribute the 1/2:

x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102

Combine like terms:

(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x)+(-338+169-56)=102

Evaluate:

\frac{1}{4}x-225=102

Add 225 to both sides:

\frac{1}{4}x=327

Multiply both sides by 4:

x=\$ 1308

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

r=\frac{1}{2}(1308)=\$ 654

And we're done!
