Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form.

IRINA_888 [86]

Answer:

$3x-4y=-40$

Step-by-step explanation:

The standard form of a linear equation is $ax+by=c$ .

The given line has equation:

$y-4=\frac{3}{4}(x+8)$

This is the point-slope form of the given line.

To find the standard form, we clear the fraction

$4y-16=3(x+8)$

We expand the parenthesis now to get:

$4y-16=3x+24$

We group the variables on the LHS and the constants on the RHS.

$4y-3x=24+16$

$-3x+4y=40$

Multiply through by -1

$3x-4y=-40$

This is of the form: $ax+by=c$ .

Last year Lira earned $12,000 less than her husband Todd. Together they earned $75,000. How much did Lira earn last year?

nexus9112 [7]

Given:

Last year Lira earned $12,000 less than her husband Todd.

Together they earned $75,000.

To find:

The amount earned by Lira in last year.

Solution:

Let x be the amount earned by Lira's husband inn last year.

Last year Lira earned $12,000 less than her husband Todd.

Amount earned by Lira = $x-12000$

Total amount earned by Lira and her husband = $x+(x-12000)$

= $2x-12000$

Together they earned $75,000.

$2x-12000=75000$

$2x=75000+12000$

$2x=87000$

$x=\dfrac{87000}{2}$

$x=43500$

Now,

Amount earned by Lira = $x-12000$

= $43500-12000$

= $31500$

Therefore, the amount earned by Lira in last year is $31500.

Write an explicit function for f(x) <br> Can anyone help me with this please I’ll mark as brainliest

stiv31 [10]

Answer:

Explicit Function:

Any function which when expressed in terms of the independent variable is called an explicit function. For example, if we write y=f(x)

, then the dependent variable y is given in terms of the independent variable x by the function f(x). Thus y=f(x) is an explicit function. But, g(x,y)=c

is not explicit as it is a combination of both x and y. Such a function is called implicit.

Step-by-step explanation:

What is meant by implicit function?

An implicit function is a function that is defined by an implicit equation. That means the equation contains several variables, including dependent and independent. In other words, it is an equation that relates one of the variables, recognized as the value of the function, with the others regarded as the arguments.

What is an explicit function?

An explicit function is a function that is represented in terms of an independent variable. For example, y = 4x – 7 is explicit where y is a dependent variable and is dependent on the independent variable x.

How do you know if a function is implicit?

If a function is written in the form f(x, y) = 0, we can say that the given function is implicit.

What is implicit function differentiation?

We differentiate or find the derivative for both sides of the equation in implicit function differentiation.

What is explicit and implicit?

In general, “explicit” means clearly stated, whereas “implicit” refers to proposed and not stated directly.
