Answer:

x = - 2√2

x = -2

Step-by-step explanation:

A . 5 + x² = 2 x² +13

    5 + x² - 2 x² - 13 = 0

      - x² -8 = 0

      - x² = 8

         x² = -8

         x = - √8

          x = - 2√2

B . 5 + x³ = 2 x³ + 13

    5 + x³- 2 x³ - 13 = 0

       - x³ -8 = 0

        -x³ = 8

         x³ = -8

      x = - ∛8

         x = -2

Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.

Step-by-step explanation:

Given: Change in water level in [tex]1 \dfrac23[/tex]  week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes

To find : The average rate at which the water level changed every week.

i.e. Change in water level per week.

As [tex]1\dfrac23 = \dfrac52[/tex]

Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]

Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.

We want to find the average rate of change at which the water level changed in a given time period.

We will find that the average rate of change is:

[tex]r = - 0.9 in/week[/tex]

We define the average rate of change as the quotient between the total change and the time it takes.

Here we have:

total change = -(1 + 1/2) in

Time = (1 + 2/3) weeks

Then the average rate of change is:

[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]

This means that the water level decreases, in average, 0.9 inches per week.

y+3 = 5(x+5)

y+3 = 5x+25 ... distribute

y = 5x+25-3 ... subtract 3 from both sides

y = 5x+22

y-5x = 22 ... subtract 5x from both sides

-5x+y = 22 .... is one possible answer

5x-y = -22 ... is another possible answer

The difference is that I multiplied both sides by -1 so that the A term becomes positive.

Rewriting the whole as an Equivalent Fraction

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 4 as the denominator :

28 28 • 4

28 = —— = ——————

1 4

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (28 • 4) x - 112

When a fraction equals zero

4.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

x-112

————— • 4 = 0 • 4

4

Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

x-112 = 0

Solving a Single Variable Equation:

4.2 Solve : x-112 = 0

Add 112 to both sides of the equation :

x = 112

One solution was found :

x = 112

Answer:

m<7 = 95 degrees

Step-by-step explanation:

Angle 1 = 3x + 10

Angle 4 = 4x-15

Because of the verticle angles theorum, Angle 1 and 4 are congruent.

So:

3x+10 = 4x-15

    +15       +15

3x+25 = 4x

-3x         -3x

25 = x

Angle 1 = 3x + 10

But now we know what x is so now its (3 times 25) + 10 which is 85

Angle 1 and 3 are a linear pair so they are supplementary (add up to 180)

180-85=95

So, Angle 3 is 95 degrees

Because of the corresponding Angles postulate, 7 and 3 are congruent

So m<7 = 95 degrees

Step-by-step explanation:

Evaluating expressions involve solving and simplifying the expression

The expressions are given as:

[tex]\mathbf{(a)\ -12 - 27}[/tex]

[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]

[tex]\mathbf{(a)\ -12 - 27}[/tex]

Subtract 27 from -12

[tex]\mathbf{-12 - 27 = -39}[/tex]

Hence, the result of [tex]\mathbf{-12 - 27}[/tex] is -39

[tex]\mathbf{(b)\ 8 + 53 * 0.4 - ( 23-3.2)}[/tex]

Start by evaluating the expression in brackets

[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 53 * 0.4 - 19.8}[/tex]

Evaluate the products

[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 8 + 21.2 - 19.8}[/tex]

Add and subtract

[tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2) = 9.4}[/tex]

Hence, the result of [tex]\mathbf{8 + 53 * 0.4 - ( 23-3.2)}[/tex] is 9.4

Answer:

x = 16

Step-by-step explanation:

3(x-4)=36

First we will distribute:

3x - 12 = 36

Add 12 to both sides:

3x = 48

Divide both sides by the coefficient:

x = 16

Check your work:

3 (x - 4) = 36

3 (16 - 4) = 36

3 (12) = 36

36 = 36

The answer is -2.3328

Answer:

x = 3 and x = -2/7

Step-by-step explanation:

you can multiple -6 by 7 = -42

and then find what adds into -19 but can multiply together to get -42.

In this case (x-21)(x+2) would work

then you have to divide out your 7 from both numbers,

(x-21/7)(x+2/7)

then you have to make them equal to zero

x-21/7 = 0                =   x = 21/7 = 3

x+2/7 = 0                 =   x = -2/7

so your final answer is x = 3 and x = -2/7
