2x + -10 = 10 + -3x

Explanation

Reorder the terms:

-10 + 2x = 10 + -3x

-10 + 2x = 10 + -3x

Solving for variable x

Move all terms containing x to the left, all other terms to the right

Add 3x to each side of the equation

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Answer

So your answer is x=4

The number of protozoa makes a series where every next term is double its previous term so on the slide now the number of protozoa is 16.

A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.

Number of protozoa 5 days ago = 1

Since protozoa double every 1.25 days.

Number of times protozoa doubles in 5 days ⇒

5 / 1.25 = 4 times.

So,

1 →2 → 4 → 8 → 16

Hence "The number of protozoa on the slide now is 16".

The equation of the line:

[tex]y=\frac{3}{2}x+9[/tex]

Step-by-step explanation:

Given

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2/3

perpendicular to m = -1/m

                                 [tex]=-\frac{1}{\left(\frac{-2}{3}\right)}=\frac{3}{2}[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 3/2 and the point (-4, 3)

[tex]y-3=\frac{3}{2}\left(x-\left(-4\right)\right)[/tex]

[tex]y-3=\frac{3}{2}\left(x+4\right)[/tex]

Add 3 to both sides

[tex]y-3+3=\frac{3}{2}\left(x+4\right)+3[/tex]

[tex]y=\frac{3}{2}x+9[/tex]

Thus, the equation of the line:

[tex]y=\frac{3}{2}x+9[/tex]

Answer:

49 miles

Step-by-step explanation:

Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.

Then the equation will be, y = 3.5x + 14

Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.

So, y = 3.5(10) + 14

y = 35+14

y=49

Using the segment addition postulate, the value of p = 5, and YZ = 9 units.

Since point Y lies between points X and Z, the three points are collinear, therefore, based on the segment addition postulate, XY + YZ = XZ.

Given the following:

XY = 3p

YZ = 2p - 1

XZ = 6p - 6

Substitute

3p + 2p - 1 = 6p - 6

Add like terms

5p - 1 = 6p - 6

5p - 6p = 1 - 6

-p = -5

p = 5

YZ = 2p - 1

Plug in the value of x

YZ = 2(5) - 1

YZ = 9 units.

The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).

The given function is f(x)=x+3.

To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.

From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.

To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.

Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.

So, f(-2.2) = −1 + 2

f(-2.2)  = 1.

Thus, the required value of f(-2.2) is 1.

0.7 is the growth factor

0.3 is the growth rate

Step-by-step explanation:

Here, we want to get the growth rate and the growth factor

Let us consider the general form of an exponential equation

That will be;

y = a(1 + r)^n

The growth rate is r

while the growth factor is the term (1 + r)

From the given exponential function;

-0.3 is the rate of increase

Growth rate is 1-0.3 = 0.7

Answer/step-by-step explanation:

We know that during their first year, the company caught 95,000 fish, and the amount of fish caught decreased 4% each year. First, let's calculate 4% of 95,000, by doing the equation: 95,000 x 0.04 = 3,800

So, each year, the company catches 3,800 less fish.

In order to find out how many fish the company caught in ten years, we need to multiply 3,800 x 10 and then subtract it from 95,000. Then we need to multiply that number by 10.

3,800 x 10 = 38,000

95,000 - 38,000 = 57,000 x 10 = 570,000.

Therefore, the company caught a total of 57,000 fish in the first ten years.

At the chili festival both restaurant (a) and (b) have the same record of winnings as they have equivalent fractions: 4/7

Information about the problem:

Calculating which restaurant has the better record, we get:

Rate (a) = Winnings restaurant a / Contest restaurant a

Rate (a) = 56/98

Simplifying, we get:

Rate (a) = 4/7

Rate (a) = 0.5714285

Rate (b) = Winnings restaurant b / Contest restaurant b

Rate (b) = 84/147

Simplifying, we get:

Rate (b) = 4/7

Rate (b) = 0.5714285

That means 56/98 and 84/147 are equivalent fractions.

Answer: x=8 and y=29

Step-by-step explanation:

Since the lines M and N are parallel to each other, the corners that are across from each other are equal. This is true for the corners formed by the lines on the top and bottom.

So, all of the given equations can be set equal to each other. ie: (5x+9)=(4x+17)=(y+20).

Now, since the first two expressions both have x as their only variable, set those equal to each other and do not include the y expression.

ie: (5x+9)=(4x+17)

Now solve for x by subtracting 4x from each side.

ie: x+9=17

Now subtract 9 from each side

ie: x=8

Now you have your X value

Use your X value to solve one of the x variable equations.

ie: 5(8)+9

This equals 49.

Use this answer to substitute it in the equation where we set them all equal.

ie: 49=y+20

Now solve for y using this equation

ie: y=29

Yes
