Answer:

x = 8

Step-by-step explanation:

Solve for x:

6 x + 9 = 4 x + 25

Subtract 4 x from both sides:

(6 x - 4 x) + 9 = (4 x - 4 x) + 25

6 x - 4 x = 2 x:

2 x + 9 = (4 x - 4 x) + 25

4 x - 4 x = 0:

2 x + 9 = 25

Subtract 9 from both sides:

2 x + (9 - 9) = 25 - 9

9 - 9 = 0:

2 x = 25 - 9

25 - 9 = 16:

2 x = 16

Divide both sides of 2 x = 16 by 2:

(2 x)/2 = 16/2

2/2 = 1:

x = 16/2

The gcd of 16 and 2 is 2, so 16/2 = (2×8)/(2×1) = 2/2×8 = 8:

Answer:

-12.25

Step-by-step explanation:

Let's investigate what happens when negative values appear under the radical symbol (as the radicand) for cube roots and square roots.

In some situations, negative numbers under a radical symbol are OK. For example, radnegnew14is not a problem since (-2) • (-2) • (-2) = -8, making the answer -2. In cube root problems, it is possible to multiply a negative value times itself three times and get a negative answer.

Difficulties, however, develop when we look at a problem such as radnegnew214. This square root problem is asking for a number multiplied times itself that will give a product (answer) of -16. There simply is no way to multiply a number times itself and get a negative result. Consider: (4) • (4) = 16 and (-4) • (-4) = 16.

CUBE ROOTS:

radnn1

BUT

SQUARE ROOTS:

n2

Yes, (-2) x (-2) x (-2) = -8.

No problem.

Nope!   (4) x (4) ≠ -16.

Nope!   (-4) x (-4) ≠ -16.

bullet Square roots are the culprits! The difficulties arise when you encounter a negative value under a square root. It is not possible to square a value (multiply it times itself) and arrive at a negative value. So, what do we do?

statement

The square root of a negative number does not exist among the set of Real Numbers.

When problems with negatives under a square root first appeared, mathematicians thought that a solution did not exist. They saw equations such as x2 + 1 = 0, and wondered what the solution n3 really meant.

In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545.

def The imaginary number "i" is the square root of negative one.

neg i

An imaginary number possesses the unique property that when squared, the result is negative.

irad1

Consider: irad2a

The process of simplifying a radical containing a negative factor is the same as normal radical simplification. The only difference is that the irad4 will be replaced with an "i ".

As research with imaginary numbers continued, it was discovered that they actually filled a gap in mathematics and served a useful purpose. Imaginary numbers are essential to the study of sciences such as electricity, quantum mechanics, vibration analysis, and cartography.

When the imaginary i was combined with the set of Real Numbers, the all encompassing set of Complex Numbers was formed.

Answer:1. 0.35. 0.35

Step-by-step explanation:

I did the question on edgenuity

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35

The table that displays the height of water when a pool is being filled against time is shown in the image attached. (See attachment).

Recall:

Rate of change can be calculated as: change in output / change in input

Change in output = difference between consecutive outputs

Change in input = difference between consecutive inputs

In the question given,

Time is input

Height is output

Thus:

Change for each consecutive input (time):

Therefore, the change of each consecutive input (time) is: 1

Change for each consecutive output (height):

Therefore, the change of each consecutive output(height) is: 0.35

Rate of change of the relationship between time and height:

Rate of change = change in height / change in time

Rate of change = 0.35/1 = 0.35

In summary:

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35

Step-by-step explanation:

The cost per message is $0.15

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, a graph,

The graph is showing a straight line,

Considering a coordinate (3, 20),

That means, they cost $20 for 3 messages.

Therefore, for 1 message = 3/20 = 0.15

Answer:

y=9

Step-by-step explanation:

5(y-10)=-5

We move all terms to the left:

5(y-10)-(-5)=0

We add all the numbers together, and all the variables

5(y-10)+5=0

We multiply parentheses

5y-50+5=0

We add all the numbers together, and all the variables

5y-45=0

We move all terms containing y to the left, all other terms to the right

5y=45

y=45/5

y=9

The value of y = 9 is correct. Therefore, the solution is y = 9.

To solve the equation 5(y - 10) = -5 for y, follow these steps:

Step 1: Distribute the 5 on the left side of the equation:

5y - 50 = -5

Step 2: Move the constant term to one side by adding 50 to both sides:

5y - 50 + 50 = -5 + 50

Step 3: Simplify the left side and evaluate the right side:

5y = 45

Step 4: Isolate y by dividing both sides by 5:

5y / 5 = 45 / 5

Step 5: Simplify and calculate y:

y = 9

The solution to the equation is y = 9. To verify, substitute y with 9 in the original equation:

5(9 - 10) = -5

5(-1) = -5

-5 = -5

Since both sides are equal, the value of y = 9 is correct. Therefore, the solution is y = 9.

Step-by-step explanation:

Differentiate using the product rule

Given y = f(x)(g(x) , then

[tex]\frac{dy}{dx}[/tex] = f(x)g'(x) + g(x)f'(x)

Here f(x) = sinx ⇒ f'(x) = cosx

g(x) = 3x² ⇒ g'(x) = 6x

Let's let A, B, C represent the sides of the triangle from shortest to longest, then:

A = ?

B = A + 2

C = A + 3

To find the perimeter we add all the sides p = A + B + C, and based on the problem

p = A + B + C

26  = A + (A + 2) + (A+3)

26 = 3A + 5

21 = 3A

7 = A

Now we can use the fact that A = 7 in, which is the shortest side, to find all three sides:

A = 7

B = 7 + 2 = 9

C = 7 + 3 = 10

The lengths  of the sides are 7 in, 9 in, and 10 in.

The equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

To determine which of the given equations has a graph with a y-intercept of -8.

We will compare the equations with the slope-intercept form of the equation of a straight line.

The slope-intercept form of the equation of a straight line is

y = mx + c

Where m is the gradient or slope

and c is the y-intercept

By comparing with y = mx + c

m = 3 and c = -8

∴ The y-intercept here is -8

By comparing with y = mx + c

m = -8 and c = 3

∴ The y-intercept here is 3

This can be written as

y = (3/8)x + 5/8

By comparing with y = mx + c

m = 3/8 and c = 5/8

∴ The y-intercept here is 5/8

This can be written as

y = (8/3)x - 5/3

By comparing with y = mx + c

m = 8/3 and c = - 5/3

∴ The y-intercept here is -5/3

Hence, the equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8
