Which of the following is an example of a linear equation in slope intercept form?

Answer:

the answer is d

Step-by-step explanation:

he swims 80 feet below so thats gonna be a negative number. he then swims up 40 feet so you would be adding . so -80+ 40 = -120

The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)

What is equation?

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.

Whale swims 80 ft below so it be a negative number.

Whale then swims up 40 ft so would be adding .

When the whale is 120 ft below the water's surface so it be a negative number.​

-80+ 40 = -120

Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120

m= -2/5

Step-by-step explanation:

Given:

Length of a rectangular monitor screen is 5 in more than it's width.

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

To find:

The length and width of the screen.

Solution:

Let width of the screen be x inches.

Length of a rectangular monitor screen is 5 in more than it's width. So,

Length of screen = (x+5) inches

Area of screen is

[tex]Area=length\times width[/tex]

[tex]A_1=(x+5)\times x[/tex]

[tex]A_1=x^2+5x\text{ in}^2[/tex]

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

New length = 2(x+5) inches

New width = (x-1) inches

So, new area is

[tex]A_2=2(x+5)(x-1)[/tex]

[tex]A_2=(2x+10)(x-1)[/tex]

[tex]A_2=2x^2+10x-2x-10[/tex]

[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]

Area increased by  170 in².

[tex]A_2-A_1=170[/tex]

[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]

[tex]2x^2+8x-10-x^2-5x=170[/tex]

[tex]x^2+3x-10=170[/tex]

Subtract 170 from both sides.

[tex]x^2+3x-10-170=0[/tex]

[tex]x^2+3x-180=0[/tex]

Splitting the middle term, we get

[tex]x^2+15x-12x-180=0[/tex]

[tex]x(x+15)-12(x+15)=0[/tex]

[tex](x+15)(x-12)=0[/tex]

[tex]x=-15,12[/tex]

Width cannot be negative. So, x=12.

Width = 12 inches

Length = 12+5 = 17 inches

Therefore, the length of screen is 17 inches and width is 12 inches.

Answer:

1. 30(8.75) + 11t = 400

2. 12.5 hours

Step-by-step explanation:

1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.

30 hours and $8.75 an hour would be equivalent to 30(8.75)

We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t

Finally, you want to earn a total of $400 a week, which means the sum equals 400

30(8.75) + 11t = 400

2. 30(8.75) = 262.5

400 - 262.5 = 137.5

137.5 / 11 = 12.5

0.833 pound of apples go into each pie.

Given Brianne has 2 and  half pounds of apples.

she can make 3 pies with no apples left.

Now total quantity of apples she has is 2.5 pound.

Since she can make 3 apple pies with 2.5 pound of apples, so each pie has equal amount of apples.

Now each pie has [tex]\frac{2.5}{3} =0.833[/tex] pounds of apples.

Hence 0.833 pound of apples go into each pie.

Answer:

y= 4x +4

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is 4, m= 4.

Substitute m= 4 into the equation:

y= 4x +c

To find the value of c, substitute a pair of coordinates.

When x= 1, y= 8,

8= 4(1) +c

8= 4 +c

c= 8 -4 (-4 on both sides)

c= 4 (simplify)

Thus, the equation is y= 4x +4.

Answer: 9/7

Step-by-step explanation:

Answer:

El primer número llamaremos = x

El segundo número llamaremos = x + 1

El tercer número llamaremos = x + 2

Calculamos

x + (x + 1) + (x + 2) = 519

x + x + 1 + x + 2 = 519

x + x + x + 1 + 2 = 519

3x + 3 = 519

3x = 519 - 3

3x = 516

x = 516/3

x = 172

El valor de "x" lo reemplazamos en: (x + 1 y x + 2)

x + 1 = 172 + 1 = 173

x + 2 = 172 + 2 = 174

Respuesta.

Los números son: 172, 173 y 174

172 + 173 + 174 = 519

Answer:

x = 9 ; 39 in. ; 156 in.

Step-by-step explanation:

Because it is a square, we know that all 4 sides are equal to each other.

This means we can take the two expressions and equal them to each other.

4x + 3 = 3(2x - 5)

4x + 3 = 6x - 15

-2x + 3 = -15

-2x = -18

x = 9

Now that we know the value of x, we can substitute it in to find the side length.

4(9) + 3

36 + 3

39 in.

Therefore, each side of the square is 39 in.

Finally, since we know all the side lengths are 39, we can find the perimeter by adding up all 4 side lengths.

p = 4(39) = 156 in.

Therefore, the perimeter of the square is 156 in.
