Which value of y mAkes the equation below true. 3y+8-7y=11

victus00 [196]

We have
$3y+8-7y=11$
First, we can combine like terms 3y and -7y to get -4y.
Then, we have $-4y+8=11$ We could then subtract 8 on both sides to get $-4y=3$
Finally, we isolate y completely by dividing both sides by -4, to get
$y=- \frac{3}{4}$

Answer: $f'(1)=\dfrac{4}{2y+1}$

<u>Step-by-step explanation:</u>

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given: 0 = 2x² - xy - y²

Derivative: 0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

y'(2y + 1) = 4x

$y'=\dfrac{4x}{2y+1}$

$\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}$

If f(x)=3^x+10x and g(x)=4x-2, find (f+g)(x)

Vikentia [17]

Hi there!

First we need to remember the following.
$(f + g)(x) = f(x) + g(x)$

Now substitute both of the formulas.
$(f + g)(x) = ({3}^{x} + 10x)+ (4x - 2)$

Work out the parenthesis.
$(f + g)(x) = {3}^{x} + 10x + 4x - 2$

And finally collect terms.
$(f + g)(x) = {3}^{x} + 14x - 2$

~ Hope this helps you!

Grace folded clothes for 25mins then she worked on a puzzle for 45mins she started folding clothes at 8:20am what time did she f

Wittaler [7]

Answer:

9:30am

Step-by-step explanation:

Given data

Start time= 8:20am

Folding time= 25min

Time spent on Puzzle= 45min

Total time = 25+45= 70min= 1:10 min

Therefore the time she finishes is

8:20+ 1:10= 9:30 am

Hence she finished by 9:30am
