Answer:

See below.

Step-by-step explanation:

Substitute the value for the variable and solve.

a.)

⇒ y = -5(3) + 17

⇒ y = -15 + 17

⇒ y = 2

b.)

⇒ y = 3(3) - 22

⇒ y = 9 - 22

⇒ y = -13

c.)

⇒ y = 2(3) - 25

⇒ y = 6 - 25

⇒ y = -19

d.)

⇒ y = 6(3) - 39

⇒ y = 18 - 39

⇒ y = -21

Answer:

X changes to Multiply symbol

Step-by-step explanation:

A)

-5 X 3 + 17

-5 X 3 = -15

-15 + 17 = 2

B)

3 X 3 - 22

3 X 3 = 9

9 - 22 = 13

C)

2 X 3 -25

2 X 3 = 6

6 - 25 = 19

D)

6 X 3 - 39

6 X 3 = 18

18 - 39 = -21

Hey there! I'm happy to help!

Our question tells us that the number of packages is p and that the number of binders is b.

Each package is $3, so for every p we have, we will have 3 more dollars. So we have 3×p, which is written as 3p.

The same goes for binders. For every binder, we have 4 more dollars, so we have 4×b which is just written as 4b.

An expression is just a number sentence without an equal sign, so something like 1+1 or 7x². The variables are just the letters or symbols that represent an unknown quantity (so 7x² is a variable expression).

Our total cost is going to be the cost of our packages and our binders, so we combine the 3p and 4b we previously came up with, so our expression is 3p+4b.

Now, we can plug in our amounts of each thing into the equation. We will insert our 3 packages in plae of the p and our 8 binders in place of the b to find our cost.

In algebra, you can also write multiplication as a number outside of a number in parentheses so 4(2)=8 for example.

3(3)+4(8)

9+32

41

So, the total cost is $41.

Have a wonderful day and keep on learning! :D

Step-by-step explanation:

divide both side by 11 and you get 1:7

Answer:

A. 0.545454 - 1/4 = 0.295454  yes this is an irrational number

C. 3.4641016 - 1/4 = 3.2141016  yes this is an irrational number

Step-by-step explanation:

A. 0.545454 - 1/4 = 0.295454  is an irrational number as the closest fraction is shown below at 3 decimal points only

As this can be converted to a fraction 147727 /500000  ≈ 0.295

B. - 4/9 - 1/4 = -0.694444444 is not an irrational number so answer is no

As this can be converted to a fraction  -173611111 / 250000000

To write 0.694444444 as a fraction you have to write 0.694444444 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

0.694444444 = 0.694444444/1 = 6.94444444/10 = 69.4444444/100 = 694.444444/1000 = 6944.44444/10000 = 69444.4444/100000 = 694444.444/1000000 = 6944444.44/10000000 = 69444444.4/100000000 = 694444444/1000000000. Then divide by 470 and we know to use this some as 250000000/531915 = 470

C. 3.4641016 - 1/4 = 3.2141016  yes this is an irrational number

closest fraction is only   4 significant figures

4017627 /  1250000

=3 and 267627 over 12500003

267627  /1250000

≈3.214  so in closer proof it is an irrational number.

D. sq rt 4 - 1/4 = 1.75 is not an irrational number as this fraction is 7/4 = 1 3/4

= -2 + -7x3/ 8 x 3 + -1 x 4 / 6x4

= -2 + -21/24 + -4 / 24

= -2 + -21 + -24

2c) y = -83

2d) y = -50

Step-by-step explanation:

1a) y = x  + 11

-30 = x  + 11

-11           -11

------------------

-41 = x

1b) y = -2x - 32

-30 = -2x - 32

-1 = x

1c) y = -3x - 1

-30 = -3x - 1

+1             +1

-----------------

-29 = -3x

/-3     /-3

------------------

29/3 = x

9.66 = x

1d) y = 5x - 10

-30 = 5x - 10

+10         +10

----------------------

-20 = 5x

/5      /5

----------------------

-4 = x

------------------------

2a) y = x + 3

y = -6 + 3

y = -3

2b) y = -2x - 72

y = -2(-6) - 72

y = 12 - 72

y = -60

2c) y = 3x - 65

y = 3(-6) - 65

y = -18 - 65

y = -83

2d) y = 4x - 26

y = 4(-6) - 26

y = -24 - 26

y = -50

Answer: 47.25

Step-by-step explanation:

the equation for finding the area of a triangle is base times height divided by 2

10.5(9)= 94.5

94.5/2=47.25

Answer:

47.25 sq ft is the area. no idea what you want me to do with the 4% though

Step-by-step explanation:

area for traingles = (base×hight)÷2

so your equation would he (10.5ft×9ft)÷2

10.5×9= 94.5

94.5÷2÷47.25

so the answer is 47.25 ft^2 (or simply sq ft)

11/3 ÷ 2/3 = 5 1/2

Step-by-step explanation:

When doing divison of fractions, you do these steps

11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.

11/3 × 3/2. Now all you have to do is multiply

11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

Step-by-step explana

The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression of subtraction is,

E = 11.5−7.2

The expression in the form of addition will be converted by changing the sign of 7.2.

E= 11.5 - (-7.2)

E = 11.5 + 7.2

Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

There are five ways to colour the centre square.

Suppose we colour the left hand side. Since the colours of the strip are symmetrical, the number to colour the right hand side is 1.

For the left part where there are 14 squares, let's consider the most adjacent square to the centre. There are four ways to colour that square since it cannot have the same colour as the centre square.

The same goes with the other squares remaining.

So, the answer is 5×4^14.

Answer:

should be 16

Step-by-step explanation:

Two "factors" are multiplies together to product another number (the product).  So, for example, the prime factors of 10 are 2 and 5.  Prime factors that, themselves, have only factors of 1 and themselves.  Non-prime numbers, like 10, have prime factors.  Note that 1 is a factor of all integers.

If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root."

Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

Practice:

   What is the square root of 49?

   What is the square root of 100?

   What is the square root of 625?

   Memorize the squares of the numbers from 1 to 10, or 1 to 20  -- that will be very helpful in math classes.

Step-by-step explanation:

The correct answer is B).

The single solution is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].

The exponent to which the base of the logarithm should be raised in order to obtain the number N is the logarithm of any number N, if interpreted as an exponential form. Numerous astronomical and scientific calculations involving large numbers can benefit from its use. As an inverse of the exponential function, logarithmic functions are closely related to exponential functions.

Given Equation

[tex]4log_\frac{1}{2} w + (2log_\frac{1}{2} u - 3log_\frac{1}{2} v)[/tex]

[tex]mlog_an = log_an^{m}[/tex]

equation is

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} u^2 - log_\frac{1}{2} v^3)[/tex]

and [tex]log_an - log_am = log_a\frac{n}{m}[/tex]

and [tex]log_an + log_am = log_amn[/tex]

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} \frac{u^2}{v^3} )[/tex]

and [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex]

Hence the equation is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].
