Answer:

[tex]y> \frac{2}{3}x+3[/tex]

Step-by-step explanation:

we have the points

(-3,1) and (0,3)

step 1

Find the slope m of the line

The formula to calculate the slope between two points is equal to

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

substitute the values

[tex]m=\frac{3-1}{0+3}[/tex]

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

step 2

Find the equation of the line in slope intercept form

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

we have

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

[tex]b=3[/tex] ----> the y-intercept is the point (0,3)

substitute the values

[tex]y=\frac{2}{3}x+3[/tex]

step 3

Find the equation of the inequality

we know that

The slope is positive

Everything to the left of the line is shaded ( The inequality is of the form y > ax+b or y ≥ ax+b)

Is a dashed line (The inequality is of the form y > ax+ b or y < ax+b)

therefore

The equation of the inequality is of the form y > ax+b

The inequality is

[tex]y> \frac{2}{3}x+3[/tex]

Answer:

The equation has only one solution

Step-by-step explanation:

* Lets explain how to solve the problem

- There are three types of solutions for the equations

Case (1)

# Two sides of the equation have different coefficient of the variable

   and same or different numerical terms, then the equation has only

   one solution

- Ex: 2x + 5 = x + 5, lets solve it

∵ 2x + 5 = x + 5

- subtract x from both sides

∴ x + 5 = 5

- Subtract 5 from both sides

∴ x = 0

- Zero is a solution

∴ The solution of the equation is x = 0

- If the numerical terms are different x will be any other value, so the

 equation has only one solution

∴ The equation has one solution

Case (2)

# Two sides of the equation have same coefficient of the variable,

  and different numerical terms, then the equation has no solution

- Ex: 14x - 20 = 14x + 10, lets solve it

∵ 14x - 20 = 14x + 10

- Subtract 14x from both sides

∴ - 20 = 10

- The left hand side not equal the right hand side , then there is

  no value of x can make the two sides equal

∴ The equation has no solution

Case (3)

# Two sides of the equation have same coefficient of the variable,

  and same numerical terms, then the equation has infinitely

  many solutions

- Ex: 3x + 5 = 3x + 5, lets solve it

∵ 3x + 5 = 3x + 5

- Subtract 3x from both sides

∴ 5 = 5

- The left hand side is equal to the right hand side , then x can be

  any value because the two sides is already equal without x

∴ The equation has infinitely many solutions

∵ He will write two expressions simplified , not equal , have different

  coefficients on the variables and equate them, then it is like

  the first case

- That means not same coefficient of the variable, and may be not

 same numerical term

∴ The equation has only one solution

Answer:

One gallon of paint is not enough to paint the bedroom floor

Step-by-step explanation:

step 1

Find the area of the bedroom floor

The area is in the shape of rectangle

so

[tex]A=(11.4)(12.5)=142.5\ ft^2[/tex]

Remember that the bedroom floor will be painted with two coats of paint

so

Multiply the area by two

[tex]A=(2)142.5=285\ ft^2[/tex]

A gallon of paint will cover approximately 150 square feet

[tex]285\ ft^2 > 150\ ft^2[/tex]

therefore

One gallon of paint is not enough to paint the bedroom floor

Final answer:

No, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.

Explanation:

To determine if one gallon of paint will be enough to paint the bedroom floor with 2 coats of paint, we need to calculate the total area of the floor and then divide it by the coverage area of a gallon of paint.

The area of the bedroom floor is calculated by multiplying the length and width together: 11.4 feet * 12.5 feet = 142.5 square feet.

Since we need to apply 2 coats of paint, we need to double the area: 142.5 square feet * 2 = 285 square feet.

Since one gallon of paint covers approximately 150 square feet, one gallon of paint will not be enough to paint the bedroom floor with 2 coats of paint.

Answer:

- 21

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ], thus

[tex]S_{14}[/tex] = [tex]\frac{14}{2}[/tex][( 2 × 18) + (13 × - 3) ]

= 7 (36 - 39) = 7 × - 3 = - 21

The sum of the arithmetic series with the first term 18, common difference -3, and 14 terms is 231.

To find the sum, Sn, of an arithmetic series where a1 is the first term, d is the common difference, and n is the number of terms, you can use the formula:
Sn = ⅓n × (a1 + an)

First, find the nth term (an) using the formula:

an = a1 + (n - 1)d

For a1 = 18, d = –3, and n = 14:

an = 18 + (14 - 1)(-3)

an = 18 - 39 = –21
Sn = ⅓(14) × (18 + (–21))

Sn = 7 × (18 - 3) × 33

Sn = 231

So, the sum of the series is 231.

[tex]-7^{\circ}F[/tex]

Step-by-step explanation:

Let x represent temperature change per hour.

We have been given that the temperature is going to steadily drop over the next 4 hours and the temperature changes by the same amount each hour.

So temperature change in 4 hours would be [tex]4x[/tex].

We are also told that the temperature changes by a total of -28°F, so we can represent this information in equation as:

[tex]4x=-28^{\circ}F[/tex]

Let us solve for x.

[tex]\frac{4x}{4}=-\frac{28^{\circ}F}{4}[/tex]

[tex]x=-7^{\circ}F[/tex]

Therefore, the temperature changes [tex]-7^{\circ}F[/tex] each hour.

Answer:

The perimeter is 30 and the angle is 53.

Step-by-step explanation:

The perimeter is found by adding the length of all four sides. Two sides are 10 units and two sides are 5 units. 10+10+5+5 = 30.

The angle is found by subtracting angle ABC's value from 180.

180 - 127 = 53.

The perimeter of a parallelogram ABCD is 30 units and the measure of angle BCD is 53°.

A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram. A quadrilateral will be a parallelogram if its opposite sides are parallel and congruent.

Given that, from given parallelogram ABCD, m∠ABC=127°.

The length of BC Is 10 units, and the length of AB is 5 units.

Here, the perimeter of of a parallelogram is AB+BC+CD+DA

= 10+5+10+5

= 30 units

Here, m∠ABC+m∠BCD=180° (Sum of co-interior angles is 180°)

127°+m∠BCD=180°

m∠BCD=180°-127°

m∠BCD=53°

Therefore, the perimeter of a parallelogram ABCD is 30 units and the measure of angle BCD is 53°.

Answer: [tex]y=8[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

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

Where "m" is the slope and "b" is the y-intercept.

We know that this is a horizontal line. This means that:

[tex]m=0[/tex]

Knowing that this line contains the point (-4,8) we can substitute  this coordinates and [tex]m=0[/tex] into [tex]y=mx+b[/tex], and then solve for "b":

[tex]8=0(-4)+b\\\\b=8[/tex]

Therefore, the equation of this line in Slope-intercept form is:

[tex]y=(0)x+8\\\\y=8[/tex]

Final answer:

The equation of the horizontal line that contains the point (-4,8) is y = 8 and it demonstrates that for a horizontal line, the slope is 0 and the y-coordinate remains constant along the line.

Explanation:

The equation of a horizontal line that contains a given point can be determined by looking at the y-coordinate of that point. Since a horizontal line has a slope of 0, the y-coordinate of any point on the line does not change. Therefore, the equation of the horizontal line that contains the point (-4,8) is simply y = 8. This equation indicates that the y-value will always be 8, regardless of the x-value, which is characteristic of a horizontal line. In the slope-intercept form of the equation of a line, which is y = mx + b, the slope (m) is 0, and the y-intercept (b) is 8.

Answer:

$157.89

Step-by-step explanation:

The original price is x

you took away 5%, making the new price 95% of x, or .95x

Put it in an equation

.95x = 150

x = 150/.95

x = 30/.19

x = 3000/19

x=157 17/19

x is about $157.89

The amount Nat's paid at the club before the discount is $157.90

Given:

Total bill including discount = $150

Discount = $5

Amount before discount = x

Total bill including discount = Amount before discount - (Discount × Amount before discount)

150 = x - (5% × x)

150 = x - (0.05 × x)

150 = x - 0.05x

150 = 0.95x

divide both sides by 0.95

x = 150 / 0.95

x = 157.89473684210

Approximately,

x = $157.90

Therefore, amount Nat's paid at the club before the discount is $157.90
