Leave the answer as an improper fraction

Ghella [55]

Hey there!

ANSWER: $\frac{23}{20}$

EXPLANATION:

To find the answer to your question, you will need to add.

$\frac{3}{4}+\frac{2}{5}$

First, multiply the denominator.

$5*4=20$

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

$5*3=15$

Now multiply 4 bu 2.

$4*2=8$

If you want to get the numerator, add what you got after multiply.

$15+8=23$

The numerator is 23. So now let's complete the fraction.

$\frac{23}{20}$

This is your answer!

Hope this helps!

Use the order pairs to find the linear equation in slope intercept form (0,10) & (3,2)

Virty [35]

$y = \frac{-8}{3}x + 10$ is the equation in slope intercept form

Solution:

Given points are (0, 10) and (3, 2)

We have to find the slope intercept form

Let us first find the slope of line

The slope of line is given as:

$m = \frac{y_2-y_1}{x_2-x_1}$

Here,

$(x_1, y_1) = (0, 10)\\\\(x_2, y_2) =(3,2)$

Substituting the values we get,

$m = \frac{2-10}{3-0}\\\\m = \frac{-8}{3}$

The equation of line in slope intercept form is given as:

y = mx + c ------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

Substitute $m = \frac{-8}{3}$ and (x , y) = (0, 10) in eqn 1

$10 = \frac{-8}{3} \times 0 + c\\\\c = 10$

$Substitute\ m = \frac{-8}{3}\ and\ c = 10\ in\ eqn\ 1$

$y= \frac{-8}{3}x + 10$

Thus the equation of line in slope intercept form is found

Below there are graphs of some inverse proportions. What function each one represent?

AysviL [449]

Answer:

y = 15/x

Step-by-step explanation:

An inverse proportion has the equation ...

y = k(1/x) . . . . k is the constant of proportionality

Solving for k, we find ...

k = xy

The coordinates of the given point can be used to find k:

k = (3)(5) = 15

Then the equation of the graph is ...

y = 15/x
