100 POINT HELP PLEASE !!!!!!!!!!! NO LINKS

NikAS [45]

y = log(3x + 4) + 2

__________________________________________________________

Y-INTERCEPT: set x = 0

y = log(3(0) + 4) + 2

y = log(0 + 4) + 2

y = log( 4) + 2

Using calculator,

y = log( 4) + 2

y ≈ 2.60 when x = 0

__________________________________________________________

X-INTERCEPT: set y = 0

y = log(3x + 4) + 2

0 = log(3x + 4) + 2

-2 = log(3x + 4)

(it's simple. Always remember that the base is 10, even though there seems to be no "smaller number" next to log)

= 3x + 4

$10^{-2}$ - 4 = 3x

[ $10^{-2}$ - 4 ] /3 = x

x = -1.33 when y = 0

__________________________________________________________

<h3>ANSWER: y-intercept is 2.60 and x-intercept is -1.33</h3>

What is the solution to the system of equations below? y = negative one-third x + 9 and y = two-thirds x minus 12 (21, 2) (21, –

lora16 [44]

Answer:

(21, 2 )

Step-by-step explanation:

Given the 2 equations

y = - $\frac{1}{3}$ x + 9 → (1)

y = $\frac{2}{3}$ x - 12 → (2)

Substitute (2) into (1)

$\frac{2}{3}$ x - 12 = - $\frac{1}{3}$ x + 9 ( add $\frac{1}{3}$ x to both sides )

x - 12 = 9 ( add 12 to both sides )

x = 21

Substitute x = 21 into either of the 2 equations and evaluate for y

Substituting into (2)

y = $\frac{2}{3}$ × 21 - 12 = 14 - 12 = 2

Solution is (21, 2 )

Muriel can do the laundry in 3 hours working alone. Rea has more experience and can do the laundry in 2 hours working alone. How

vagabundo [1.1K]

Here we have a problem of rates of work, where we want to find the rate at which two people would work together, so we can find the time it takes to complete a given job when these two work together..

We will find that they need to work for 6/5 hours to do the laundry together.

---------------------------------------

We know that:

Muriel can do the laundry in 3 hours.
Rea can do the laundry in 2 hours.

<em>Then we can define:</em>

M = rate at which Muriel works = 1/3h
R = rate at which Rea works = 1/2h

Where the rates are computed as the quotient between 1 (1 total laundry completed) and the amount of time it takes to do it.

If they work together, the rate just adds up, so we will have:

rate = (M + R) = 1/3h + 1/2h

Now we need to write that as a single fraction, so we get:

rate = 1/3h + 1/2h = 2/6h + 3/6h = 5/6h

Now we can write an equation of the form:

rate*time = 1

Where the 1 again, means "one complete laundry done".

Then we have:

(5/6h)*T = 1

T = (6/5)h

This means that they need to work for (6/5) hours to do the laundry together.
