Answer:

I believe this question should have several options or else you can simply name a any equation that satisfy the following:

Step-by-step explanation:

since the line is perpendicular to y = 4/3x - 7, the products of their slopes will be = -1.

so, slope x 4/3 = -1

slope = -3/4

any equation that has gradient/slope = -3/4 would be correct

Choose the slope-intercept form of 3x + 2y = 5

wlad13 [49]

Answer:

y = -3/2x + 5/2

Step-by-step explanation:

slope intercept form is y = mx + b

so we have to solve the equation for y

2y = 5 - 3x

y = 5/2 -3/2x

y = -3/2x + 5/2

There are 820 people at a stadium. 65% of them are adults, 20% of them are boys, and the rest are girls. How many girls are ther

jasenka [17]

Answer:

Final answer is 123.

Step-by-step explanation:

Given that there are 820 people at a stadium.

Out of which 65% are adults, 20% of them are boys, and the rest are girls.

Now we need to find about how many girls are there at the stadium?

We know that total percent can be 100%

So percentage of girls in the stadium = (Total %) - (Adults %) - (Boys %)

= 100% - 65% - 20%

= 100% - 85%

= 15%

Then total number of girls at the stadium = 15% of 820

= 0.15 ( 820)

= 123

Hence final answer is 123.

Write two integers whose products is negative?

yKpoI14uk [10]

Answer:

Any negative integer and any positive integer.

Like -5 and 3.

Step-by-step explanation:

In multiplication, <u>a positive number and a negative number will result in a negative product</u>.

So, you can use any positive integer and multiply it by any negative integer to get a negative product.

Using the integers I gave:

$-5*3 = -15$

Consider the function g(x) = (x-e)^3e^-(x-e). Find all critical points and points of inflection (x, g(x)) of the function g.

Elden [556K]

Answer:

The answer is " $cirtical\ points \ (x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})$ "

Step-by-step explanation:

Given:

$g(x) = (x-e)^3e^{-(x-e)}$

Find critical points:

$g(x) = (x-e)^3e^{(e-x)}$

differentiate the value with respect of x:

$\to g'(x)= (x-e)^3 \frac{d}{dx}e^{e-r} +e^{e-r} \frac{d}{dx}(x-e)^3=(x-e)^2 e^{(e-x)} [-x+e+3]$

critical points $g'(x)=0$

$\to (x-e)^2 e^{(e-x)} [e+3-x]=0\\\\\to e^{(e-x)}\neq 0 \\\\\to (x-e)^2=0\\\\ \to [e+3-x]=0\\\\\to x=e\\\\\to x=e+3\\\\\to x= e,e+3$

So,

The critical points of $(x,g(x))\equiv (e,0),(e+3,\frac{27}{e^3})$
