Answer:

x = ± 6

Step-by-step explanation:

1: Subtract both sides by -54

[tex]-1.5x^2=-54[/tex]

2: Divide both sides by -1.5

3: Take both sides to the 1/2 power

[tex]x= 6, -6[/tex]

Step-by-step explanation:

the usual line equation is

y = mx + b

I personally rather write it

y = ax + b

but really, all letters are possible as needed (particularly, if certain letters are already used for other parts of the problem definition).

what is important is to understand the messaging of the parts of such equations independently of what letter is used for what.

the factor of x (usually m in these equations) is the slope of the line, its incline. it is expressed as the ratio "y coordinate change / x coordinate change" when going from one point on the line to another.

the constant term (often called b in these equations) is the y-intercept (the y value when x = 0, indicating where the line is intercepting the y-axis).

I guess the equation in your problem actually looks like

2 + 3x + 5 - 2x = y

so, let's combine similar terms

3x - 2x + 2 + 5 = y

x + 7 = y

and now compare this to the general line equation, and we find

m = 1

b = 7

the surface area of a cone: πr²+πLr

L = the slant height

r = radius of the base

r = 40 in : 2 = 20 in

L = 50 in

The surface area:

=π.20² + π.50.20

=1256+3140

=4396 in²

Positive,

because 2*12 equals to 24, and 24 is positive!

it is 10 first subtract 40 from 25 percent and then subtract 15 from 5

Answer:The y intercept would be 55.

Step-by-step explanation:Wherever the y-axis is touched at with the x-value at 0 (in this case, its 55) that would be the y-intercept.

Answer:

[tex]\huge\boxed{\sf{55}}[/tex]

Step-by-step explanation:

Hello.

In order to determine the y-intercept, just look at the y-coordinate (If we have a point like (0, b)

b --> y-intercept

Therefore, b (the y-intercept) is equal to 55.

I hope it helps.

Have a great day.

The reading of the books are illustrations of linear equations

The term that describes the scenario is linear equations

From the question, we have:

Logan

Books = 14

Rate = 1 per week

Mariko

Books = 12

Rate = 1 per week

So, the equations that represent the number of books read in x weeks are:

Logan: y =14 + x

Mariko = 12 + x

The above equations are linear equations

Using a geometric sequence, it is found that the rule for the number of matches played in the nth round is given by:

[tex]a_n = 64\left(\frac{1}{2}\right)^n[/tex]

The rule makes sense for values of n of at most 6, as in the last round, which is the 6th and final round, 1 game is played.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem, we have that:

Thus, the rule is:

[tex]a_n = 64\left(\frac{1}{2}\right)^n[/tex]

The last round is the final, in which 1 game is played, hence:

[tex]1 = 64\left(\frac{1}{2}\right)^n[/tex]

[tex]\left(\frac{1}{2}\right)^n = \frac{1}{64}[/tex]

[tex]\left(\frac{1}{2}\right)^n = \left(\frac{1}{2}\right)^6[/tex]

[tex]n = 6[/tex]

Hence, the rule makes sense for values of n of at most 6, as in the last round, which is the 6th and final round, 1 game is played.

Answer:

decrease of 80%

Step-by-step explanation:

See image.

Use variables for the fraction.

Numerator means the top number.

Denominator means the bottom number.

Change percents to decimals to calculate.

.8 is 80%.

80% will make the whole fraction smaller.

see image

Answer:

The fraction will decrease by 20%.

You can suppose other fractions too you will get the same answer though.

Step-by-step explanation:

Let the fraction be 1/2

Now,

1/2

=> 1 + 20% of 1 => 1 + 20/100 => 6/5

=> 2 + 50% of 2 => 2 + 1/2 * 2 => 2 + 1 => 3

so,

6/5/3 => 2/5

Now,

1/2 - 2/5 => 1/10

Now,

1/10/1/2 * 100%

= 1/5 * 100%

= 20%

Answer:

The slope-intercept form of a linear equation is y = mx + b. In the equation, x and y are the variables. The numbers m and b give the slope of the line (m) and the value of y when x is 0 (b). The value of y when x is 0 is called the y-intercept because (0,y) is the point at which the line crosses the y-axis.

Answer:

-6 5/7

Multiply the denominator by the number that doesn't exceed -47. Here, it would be -6.

7 x (-6) = -42

Then, subtract the difference to get the mixed number.

-42-5 = -47

The numbers used are found in the improper fraction: -6 5/7

Answer:

[tex]-6\frac{5}{7}[/tex]

Step-by-step explanation:

Given the following question:

[tex]-\frac{47}{7}[/tex]

To convert an improper fraction into a mixed number we simply have to divide the numerator by the denominator.

[tex]-\frac{47}{7}[/tex]
[tex]-\frac{47}{7}=47\div7=-6\frac{5}{7}[/tex]
[tex]=-6\frac{5}{7}[/tex]

Let 6 represent how many times 7 does into 47
Let 5 represent the remainder
Let 7 represent the denominator which remains the same.

what are we sloving

The expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π

The function is given as:

f(x) = 5sin(x/12) + 14.5

When the temperature is 17°C, the equation becomes

5sin(x/12) + 14.5 = 17

Subtract 14.5 from both sides

5sin(x/12) = 2.5

Divide both sides by 5

sin(x/12) = 0.5

Take the arc sin of both sides

x/12 = π/6

Multiply both sides by 12

x = 2π

Hence, the expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π
