Yup correct :D
thrs a shorter method though

Imagine +4 flying over the = sign, and just change the sign (from + to -)
It is a lot shorter, as long as you can visualise. If for example -10 is flying over, it becomes +10

How does water help living things? Check all that apply.
Triss [41]
Hey there!

The answers would be

A. reproduction
B. temperature regulation
C. oxygen transportation
D. heat absorption
E. nutrient reproduction or ALL OF THE ABOVE

Water keeps all of your organs and cells functioning properly including the reproductive cells (egg, sperm) and reproductive organs (brain, ovaries, uterus, testes, thyroid). It also naturally flushes out toxins in the body. For men, semen production and semen volume can be reduced by not drinking enough water.

Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells.

Water has a high heat capacity (an ability to absorb heat) because for water to increase in temperature, water molecules must be made to move faster within the water; doing this requires breaking hydrogen bonds (the H2 in H2O) and the breaking of hydrogen bonds absorbs heat.

Living organisms need water to survive. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.

Hope this helps!

Find the Derivative y’ implicitly.
Brums [2.3K]

e^{x^2y} - e^y = e^y(e^{x^2} - 1) = x

<em>We should ISOLATE x</em>

<em />e^y= \frac{x}{e^{x^2} - 1}

<em>Find the Natural Log of Both Sides to Make the Left Side "y"</em>

<em />y = ln(\frac{x}{e^{x^2}-1})

<em>Now, FIND THE DERIVATIVE Using Chain Rule!!!</em>

<em />y' = \frac{1}{\frac{x}{e^{x^2}-1}} * \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2}= {\frac{e^{x^2}-1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2} = {\frac{1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)} =  {\frac{1}{x}}* \frac{(e^{x^2}-1 - 2x^2e^{x^2})}{(e^{x^2}-1)}

The pie chart below illustrates the future plans of 200members of St.Thomas graduating class.
ruslelena [56]

Answer:

<h2>a) approximately 133 graduates</h2><h2>b) approximately 120°</h2>

Step-by-step explanation:

a) the number of graduates planning to continue studying :

= (37 1/2% + 12 1/2% + 16 2/3%) × 200

=\frac{\left( 37\frac{1}{2} +12\frac{1}{2} +16\frac{2}{3} \right)  }{100} \times200

= (37.5 + 12.5 + 16.666666666667)×2

= 133.333333333334

…………………………………

b) the measurement of the angle representing those who plan to work :

= (360× 33 1/2)÷100

= (360× 33.333333333333)÷100

=119.999999999999

Solve the system of equations. Show your work.<br> y = x^2 -3x +4 <br> x + y = 4
sesenic [268]

Answer:

x + y = 2 ,  y = x 2 − 4 x + 4

Replace all occurrences of  

y

with  x 2 − 4 x + 4

in each equation.

x 2 − 3 x + 4 = 2 y = x 2 − 4 x + 4

Solve for  

x

in the first equation.

x = 2 , 1 y = x 2 − 4 x+ 4

Replace all occurrences of  

x  with  2

in each equation.

y=0 x = 2

Replace all occurrences of  x

with  1

in each equation.

y = 1 x = 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

( 2 , 0 ) ( 1 , 1 )

The result can be shown in multiple forms.

Point Form:

( 2 , 0 ) , ( 1 , 1 )

Equation Form:

x=2 , y = 0 x = 1 , y = 1
