All you have to do to solve this problem is to put it into fraction form: if for every $4 Jo makes, Leila makes $3, then the fraction would be 3/4.

To solve this divide 60 by 4 to get 15 and then multiply 15 by 3 to get Leila's pay. 15*3=45

Check it by putting it into simplest form as a fraction to see if it checks:

45/60=3/4 and 3/4=3/4 so therefore Leila makes $45 in profit

write equation that has base of 3 stretched vertically by factor of 2/3 reflected in y axis, asymptote of y=2 and passes through

madam [21]

The exponential equation is $y = \frac23(3)^{-x+0.74} + 2$

<h3>How to determine the equation?</h3>

An exponential function is represented as:

$y = b^x$

The base is 3.

So, we have:

$y = 3^x$

It is stretched vertically by 2/3.

So, we have:

$y = \frac23(3)^x$

When reflected over the y-axis, we have:

$y = \frac23(3)^{-x}$

An asymptote of y = 2, makes the function becomes

$y = \frac23(3)^{-x} + 2$

Lastly, it passes through the point (0, 3.5).

So, we have:

$y = \frac23(3)^{-x+h} + 2$

This gives

$3.5 = \frac23(3)^{-0+h} + 2$

$3.5 = \frac23(3)^{h} + 2$

Subtract 2 from both sides

$1.5 = \frac23(3)^{h}$

Multiply by 3/2

$2.25 = (3)^{h}$

Take the logarithm of both sides

log(2.25) = h * log(3)

Solve for h

h = 0.74

Substitute h = 0.74 in $y = \frac23(3)^{-x+h} + 2$

$y = \frac23(3)^{-x+0.74} + 2$

Hence, the exponential equation is $y = \frac23(3)^{-x+0.74} + 2$

300-297+294-291+288-285+...+6-3

vladimir2022 [97]

300 - 297 = 3

294 - 291 = 3

288 - 285 = 3

So, that is a sequence of sums of number 3: 3 + 3 + 3 + .... + 3

How may times will the number 3 be added?

Note that 300 is reduced in 6 units each time => 300 / 6 = 50 => 3 will be added 50 times.

=> 50 * 3 = 150

Answer: 150

(PLEASE! I NEED HELP! ASAP)

belka [17]

Answer:

74.4°F?

Step-by-step explanation:

It started at 65°F and they recorded the change. So 65 + 2.5 = 67.5 - 1.7 = 65.8 + 5.5 = 71.3 + 3.1 + 74.4? I think that is how it is solved. I could be wrong... it's been a while haha

^^That is finding the full temp. overall. If you are looking for the change, it is 9.4

Please help me! I have a test and I really wanna pass it!!!

Dahasolnce [82]

Answer:

Step-by-step explanation:

We have the expression 3n - 5, which we know the value of n is 4. We are asked to solve.

Since we know that n = 4, we can substitute 4 with n in the expression :

3(4) - 5

12 - 5

What is 3-2x>-5 in an inequality form

Annette [7]

Answer:

$\displaystyle 4 > x$

Step-by-step explanation:

3 - 2x > −5

- 3 - 3

_________

$\displaystyle \frac{-2x}{-2} > \frac{-8}{-2} \\ \\ x < 4$

Whenever you divide\multiply by a negative, you reverse the inequality symbol.

** The above answer is written in reverse, which is the exact same result.

I am joyous to assist you anytime.
