The graph of the combined inequality, 1 < y + 7x ≤ 12, is shown below. The correct graph is graph b.

From the question, we are to graph the given inequality

The given inequality is

1 < y + 7x ≤ 12

First, we will separate the inequality

1 < y + 7x and y + 7x ≤ 12

1 < y + 7x

We will determine two points on the line

1 = y + 7x

When x = 0

1 = y + 7(0)

1 = y

y = 1

(0, 1)

When y = 8

1 = y + 7x

1 = 8 + 7x

1 -8 = 7x

-7 = 7x

x = -7/7

x = -1

(-1, 8)

We can use these two points to plot the line of 1 < y + 7x

Also,

We will determine two points on line y + 7x ≤ 12

y + 7x = 12

When x = 0

y + 7(0) = 12

y + 0 = 12

y = 12

(0, 12)

When y = 5

5 + 7x = 12

7x = 12 - 5

7x = 7

x = 7/7

x = 1

(1, 5)

We can use these two points to plot the line of y + 7x ≤ 12

The graph of the combined inequality, 1 < y + 7x ≤ 12, is shown below. The correct graph is graph b.

The time when the two total costs would be equal is 6 hours.

The equation that can be used to represent the total cost of renting a canoe is a linear function. A linear equation is an equation that has a single variable raised to the power of 1.  A linear equation increases by a predetermined constant. An example of a linear equation is 2x + 2.

The form that the equation would be is:

Total cost = rental fee + (cost per hour x number of hours)

Total cost at Shop A = $2 + $5h

Total cost Shop B = $8 + $4h

When the total costs are equal, the two above equations would be equal.

$2 + $5h = $8 + $4h

Combine similar terms: $$5h - $4h=  $8 - $2

Add similar terms: h = 6 hours

Answer: There are 12 volleyball players

Step-by-step explanation:

If the ratio of basket to volleyball players is 5:2 and there are 30 known basket ball players that means the ratio can be written as 30:x.

If 30 is 5 parts (5x) and volleyball players is 2 parts (2x)  we need to figure out the value of 1 part (x)

This can be done by

5x=30

x=6

Now we know what 1 part is, we can now use that two figure out 2 parts

2x or 2(6)

2(6) = 12

So the ratio is 30:12. This can be confirmed by dividing both sides of the radio by 6 to get 5:2

He will earn 2603.16 dollar in one year.

An expression is a collection of terms that have been joined together using the operations +, -, or x, such as 4 x 3 or x 2 - x y + 17.

Two expressions are said to be equal in value by an equation, such as 4 b 2 = 6.

Given:

A copy of the entire query is provided below:

45w+ 155

He will therefore save

so,  w=6.

Knowing that a year equals 52 weeks

Also,

w=52 and

w²/25+45w+155

Thus,

=52*52/25+45*52+155

=108.1602340+155

The given algebraic equation  formula i.e., [tex](a^{2} -b^{2} )=(a+b)(a-b)[/tex] is verified for the given values of a and b of -3 and -5 respectively.

As per the question statement, we are supposed to verify the algebraic equation formula

[tex](a^{2} -b^{2} )=(a+b)(a-b)[/tex]

We are given that a = -3 and b = -5

Now substituting the values of a and b in the  algebraic equation formula

[tex](a^{2} -b^{2} )=(a+b)(a-b)\\LHS = (a^{2} -b^{2} )\\LHS= ([-3]^{2} -[-5]^{2} )\\LHS=(9-25)\\LHS = -16[/tex]

LHS = Left hand side of the equation

Now considering RHS i.e., Right hand side

[tex]RHS = (a+b)(a-b)\\RHS = ([-3]+[-5])([-3]-[-5])\\RHS= (-8)(2)\\RHS = -16[/tex]

As Left Hand Side LHS = Right Hand Side RHS

Hence the equation, [tex](a^{2} -b^{2} )=(a+b)(a-b)[/tex] is verified for the given values of a and b and is true for all real values of a and b.

Step-by-step explanation:

Using the length of the perimeter of the Pacman is: 29.29 mm.

Length of an arc = ∅/360 × 2πr

The length of the perimeter of the Pacman = length of the larger arc formed + 2r

∅ = 360 - 55 = 305°

r = 4.00 mm

The length of the perimeter of the Pacman = ∅/360 × 2πr + 2r

Substitute

The length of the perimeter of the Pacman = 305/360 × 2π(4.00) + 2(4.00)

The length of the perimeter of the Pacman = 21.29 + 8.00

The length of the perimeter of the Pacman = 29.29 mm

Answer:

x - 7 = -25

Step-by-step explanation:

The value of x is,

→ x = -18

Then the value of x - 7 will be,

→ x - 7

→ -18 - 7

→ -25

Hence, the answer is -25.

The number can be -3, -2, -1, 0 ,1

Here, we are given that twice a number is increased by three and the result is between negative three and seven.

Let the number be x

Twice of the number = 2x

Four more than twice the number = 2x + 4

This number is between -3, 7

⇒ -3 < 2x +4 < 7

subtracting 4 from both sides we get

-3 -4 < 2x < 7 - 4

-7 < 2x < 3

Dividing both sides by 2 we get

-7/2 < x < 3/2

- 3.5 < x < 1.5

Thus the original number lies between -3.5 and 1.5

Answer:

#1 = -2

Step-by-step explanation:

First, we need to make -2 2/3 an improper fraction. An improper fraction is a fraction whose numerator is bigger than its denominator.

you first multiply the whole number (ignoring the negative sign for now) by the denominator:

2*3=6

then you add the numerator:

6+2=8

finally you put that number over the denominator and then put the negative sign back:

-8/3

Next, you can use keep change flip to solve the division

You keep the first fraction, change the division sign to a multiplication sign, and flip the numerator and the denominator of the second fraction:

-8/3 divided by 4/3 becomes -8/3 x 3/4

finally you multiply across as you would normally and simplify

-8/3 x 3/4= -24/12

-24/12 simplified is -2
