Xy - 5 = k (move the known term to the right with changed sign)

xy = k + 5

Now we have x multiplied for y...to delete the y, divide both terms for y.

xy/y = (k+5)/y

x = (k+5)/y

3y + 5x = 7

Move 3y to the right with changed sign (this to make x the variable for which we solve the equation)

5x = 7 - 3y

Divide every term for 5

5x/5 = 7/5 - 3y/5

x = 7/5 - 3y/5

m/n = p-6

Multiply both terms for n, since we should delete the fraction m/n

m = pn-6n

Factor...

m = n(p-6)

to find n, move m to the right with changed sign.

Divide both for p-6

m/p-6 = n

n = m/p-6

F = 9c/5 + 32

9c/5 + 32 = F

Move 9c/5 to the left (don't change sign) to make it the default variable. And move all the rest to the right but changing sign.

9c/5 = f - 32

To delete the fraction, multiply every term for 5

9c = 5(f) + 32(5)

9c = 5f - 160

Divide both for 9

c = 5f/9 - 160/9

Tomas wrote the equation y = 3x +y equals 3 x plus StartFraction 3 over 4 EndFraction.. When Sandra wrote her equation, they dis
BaLLatris [955]

Answer:

-6x+2y=\frac{3}{2}

Step-by-step explanation:

The equation Thomas wrote is:

y=3x+\frac{3}{4} ...equation 1

Let us subtract 3x from both sides to get:

-3x+y=\frac{3}{4}

We now multiply through by 2 to get:

-6x+2y=\frac{3}{2} ....equation 2

We can see that equation one and two are equivalent and hence have the same solution.

Therefore Sandra's equation is -6x+2y=\frac{3}{2}

Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)
SIZIF [17.4K]

Answer:

f(-1)=19

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

f(x)=3x^2+16

Find f(-1):

f(-1)=3(-1)^2+16

f(-1)=3(1)+16

f(-1)=3+16

\boxed{f(-1)=19}

<h3>What is a graph?</h3>

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The graph for the given question is attached below.

As it can be seen that the y-axis shown the distance between Eli's location and his home, since the distance is starting to decrease when the time is 120 seconds, therefore, it can be concluded that Eli rode his bicycle home from the library.

Hence, the correct option is C.
