Answer:

X = 5

Step-by-step explanation:

Input the y into the equation:

-3 = -2x + 7

Subtract 7 on both sides:

-10 = -2x

Divide -2 on both sides:

5 = x

Hope this helps :)

Margarita [4]

Answer:

a, the first option

Step-by-step explanation:

You solve the inequality equation just like any other equations. The only difference is that you gotta flip the sign whenever you multiply or divide by a negative number.

The result is p>32, which is an open-circle at 32 that points toward all values greater than 32

A strain of bacterial cells doubles inpopulation every 2 days. A single cell is placed in a dish with sufficient nutrients to su
ArbitrLikvidat [17]

The equation that will calculate the number of days after which there will be 256 bacterial cells in the dish is 2^(d/2) = 256

<h3>How to determine the equation of the number of days?</h3>

The given parameters are:

Rate, r = doubles every two days

Initial number of strain, a = 1

This means that the function is an exponential function.

An exponential function is represented as:

A(d) = a * r^d

Since the strain doubles every two days, we have:

A(d) = a * r^(d/2)

Substitute the known values in the above equation

A(d) = 1 * 2^(d/2)

Evaluate the product

A(d) = 2^(d/2)

When there are 256 bacterial cells, the equation becomes

2^(d/2) = 256

Hence, the equation that will calculate the number of days after which there will be 256 bacterial cells in the dish is 2^(d/2) = 256

Identify the properties<br><br> 5+(2+7)=(5+2) +7<br> ^2 + ( + ) = ^2+ ( + )<br> h+0=h
TiliK225 [7]
1) 5 + ( 2 + 7) = (5 + 2) + 7

It is the associative property of the addition.

This property states that when adding 3 numbers, the grouping or association of the numbers does not change the result.

2) <span>The second expression is unreabable
</span>

<span>3) h + 0 = h
</span>

<span>It is the identity property.
</span>

This property states that 0 is the identity element of the addition and any number added to  it is equal to the same number.

AS  you know, 5 + 0 = 5, 1234 + 0 = 1234; 0 + 2548 = 2548.

Natalka [10]

Answer:

0.267mm^3

Step-by-step explanation:

Radius of the Bubble = 0.7 mm

Volume of the bubble is given by the formula :

r=\sqrt[3]{\frac{3V}{4\pi } }

Taking cube on both sides

V=\frac{4\pi\times r^3 }{3}\\\\ V=\frac{4\times3.14\times(0.7)^3}{3}\\\\V=\frac{12.56\times 0.064}{3}\\\\ V=\frac{0.804}{3}\\\\V=0.267mm^3
