Graph each linear inequality. -x+y is greater than or equal to 2

1 answer:

6 0

-X+y is greater than or equal to 2... Multiply (1y) by 2 to get the answer for x which is 2.. and multiply (-1) by 2 to get y which is -2.. So to graph it you will put Y=-2 and X=2..

Find the volume and round to the nearest tenth as needed

monitta

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is $V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}$

The volume of the smaller cone is $V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi$ .

So, the volume is $\frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}$

Which expression can be used to calculateof formalin needed make this batch of 3200 pd the amount? The batch sugar 3% water 39%

Anit [1.1K]

The appropriate expression to identify the amount of formalin is: x = 3200 ÷ 100 × 44%

<h3>How to identify the amount of formalin?</h3>

To calculate the amount of formalin in this substance we must perform the following mathematical operation:

3200 ÷ 100 = 32
32 × 44% = 1,408

According to the above, the mathematical expression would be:

X = 3200 ÷ 100 × 44%

Write the inverse function, <br> f^-1 (x), for the function <br> f (x) = 2x + 3

cricket20 [7]

$f(x) = 2x + 3$

$y = 2x + 3$

Subtract the sides of the equation minus 3

$y - 3 = 2x$

Divided the sides of the equation by 2

$\frac{y - 3}{2} = x \\$

So ;

${f}^{ - 1}(x) = \frac{x - 3}{2} \\$
