Answer:

x=-2

Step-by-step explanation:

6(x+1)=-2(3x+9)

Distribute the 6.

6x+6=-2(3x+9)

Distribute the -2.

6x+6=-6x-18

Move the variable to the left-hand side and change the sign.

6x+6+6x=-18

Collect like terms

12x=-18-6

Calculate the difference.

12x=-24

Divide both sides by 12.

x=-2

Answer:

27[tex]x^{12}[/tex]

Step-by-step explanation:

Long way:  3x^4)^3 means that 3x^4 will be multiply by itself three times

[tex](3x^{4})^3 = (3x^{4})(3x^{4} )(3x^{4} ) =27x^{12}[/tex]  

Short way   [tex]3^{3}[/tex] ([tex]x^{4(3)}[/tex] ) = 27[tex]x^{12}[/tex]

Answer:  3 seconds

Step-by-step explanation:

h(t) = -16(t)^2 + 112(t)

Set h(t) = 192 feet

192 = -16(t)^2 + 112(t)

0 = -16(t)^2 + 112(t) - 192

Solve using the quadratic formula:  There are two solutions, 3 and 4 seconds.  Three seconds is the first time it reachers 192 feet,  At four seonds it's on its way down.

The function can also be graphed (attached).

Step-by-step explanation:

Formulas and Formats we'll be using:

Slope Formula: [tex]m=\frac{y2}{x2} -\frac{y1}{x1}[/tex]

Slope-Intercept form: [tex]y=mx+b[/tex]

m = slope

b = y-intercept

Substitute (-6, 10) and (-3, -2) into the slope formula:

[tex]m=\frac{-2}{-3} -\frac{10}{-6}[/tex]

Simplify:

[tex]m=\frac{-12 \div 3}{3 \div 3}=\frac{-4}{1}[/tex]

[tex]m=-4[/tex]

*Per every -4 y, x increases by 1.

Points Included:

(-6, 10)

(-5, 6)

(-4, 2)

(-3, -2)

(-2, -6)

(-1, -10)

(0, -14)

Y-intercept:

Y-intercept represents x when it's equal to 0.

Using our points, we can determine that the y-intercept is at the point:

(0, -14)

-14 is the y-intercept.

Create a Slope-intercept form equation:

Formula: [tex]y = mx + b[/tex]

Substitute the slope, and y-intercept into the equation:

[tex]y=-4x-14[/tex]

Your equation is: [tex]y=-4x-14[/tex]

$10.75 is the cost of an adult ticket

Answer:

£10.75

Step-by-step explanation:

6 tickets=£40.50

cost of adult=£6 more than a child's

let's form an equation!

x is the cost of children tickets and since we have 4 of them it leaves us with 4x. And an adult ticket is £6 more than a child's, so that leaves us with 6+x. And since we have 2 of them we get 2(6+x). So with this info, we can make an equation and solve it to find x:

2(6+x)+4x=40.50

12+2x+4x=40.50

12+6x=40.50

6x=28.50

x=4.75=the cost of a child ticket

adult ticket =£10.75

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Because the male teacher number is 2/3 of the female teachers, we can count the female teacher number as 3/3. and since we have a ratio of 2/3 to 3/3 we can take out the 3 and think of it as 2 to 3. Since it is 2 to 3, we have 5 in total and you can divide 75 by 5 which will get you 15 (how many teachers per unit in the ratio) and if you multiply 15 by 2, you will get the male teacher number which is 30, and when you multiply 15 by 3, you will get the female teacher number which is 45, and when you subtract them, you will get 15 more female teachers.

Hope it helped!

There are 15 more female teachers than the male teachers.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given that, The number of male teachers is 2/3 of the number of female teachers in a school and there are 75 teachers altogether,

Let there be 6x female and 4x male teachers in the school,

Establishing the equation,

6x + 4x = 75

10x = 75

x = 7.5

Number of more females = 6x-4x = 2x = 2(7.5) = 15

Hence, there are 15 more female teachers than the male teachers.

Hello!

After reading the question you have provided I have come up with the correct numerical expression:

4x5-1

Step-by-step explanation:

To come up with this solution you need to keep in mind some of the terminoloy being used.

The word "subtract" comes from the action of subtraction

The word "product" comes from the action of multiplication

Thus, using those terminologies correctly, you can then deduce that when the question says "the product of 4 and 5" means "multiplying 4 and 5 together".

So you get the first part being 4x5

Then, you add in the last part of "subract 1" from the "product of 4 and 5":

4x5-1

Remember to keep in mind the rule of "PEMDAS"

You always need to keep the multiplication portion of the equation in front of any subtraction, or addition in any given equation.

Here to form the numerical expression we will first do the product of 4 and 5 and then subtract 1 from their resultant and that is ou required answer.

A numerical expression is written in terms of numbers and their operations numerical expression can of many types for example arithmatic expression , alzebraic expression etc.

some examples of arithmatic operations are -

240+130 = 370

240÷12 = 20

Some examples of alzebraic expressions are

3x + 4y = 7

x² + 3x - 7 = 0

In the given question subtract 1 from the product of 4 and 5 can be expressed as (4x5) - 1 = 20 - 1 = 19
