Answer:

y<=-3x-3

Step-by-step explanation:

m=y2-y1/x2-x1

m=-6-3/1-2

m=-3

y-y1=m(x-x1)

y-3=-3(x-(-2))

y-3=-3x-6

y=-3x-6+3

y=-3x-3

we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x-3

Answer: 37/100

Step-by-step explanation:

The fraction of a kilometer that he walked in all would be the sum of 27/100 and 1/10.

To add them, first find the lowest common multiple of both denominators. This number is 100 so will be the denominator.

Divide 100 by each denominator and multiply it by the numerator:

= (27 + 10) / 100

= 37/100

Note: 100/10 = 10

= 10 * 1 = 10 which is the second numerator.

Answer:

C = 25 + 3n

Step-by-step explanation:

Andre has a summer job selling magazine subscriptions.

We are told that:

Andy earns $25 per week plus $3 for every subscription he sells.

Let us represent

C = Total amount of money he makes this week

n = the number of magazine subscriptions Andre sells this week.

Hence, Our Algebraic expression =

C = $25 + $3 × n

C = 25 + 3n

Answer:

[tex]150 km^{2}[/tex]

Step-by-step explanation:

Use the surface area equation of cylinder: [tex]A = 2\pi rh + 2\pi r^{2}[/tex]

The diameter is 6 km but you need the radius for the formula, so you divide the diameter by 2.

6÷2 = 3 --> r = 3

You already know h, aka the height.

Plug everything into the equation.

Answer:

150.72

Step-by-step explanation:

im usin 3.14 as pi btw

the term net means like imagine you unfold the shape like the walls of the shape are paper. its now a 2d net, which includes a rectangle and two circles.

so, surface area of a circle is pi r^2 so 3.14 * 3 * 3 = 28.26

times two cause theres two circles; top and bottom :3

56.52 = 28.26 * 2

rentangle surface area = h*l

the height of the rectangle is 5 and the length is the circumference of the circle

circumference is 2*3.14*r, which in this problem, is 3

2*3.14*3 = 18.84

now, h*l is 18.84*5 = 94.2

94.2 + 56.52 = 150.72

Answer:

Top right option: g(x) = (x+1)(x-3)

Step-by-step explanation:

x=-1 is the solution to x+1=0

x=3 is the solution to x-3=0

Therefore, your expression so far is (x+1)(x-3) or x²-2x-3.

Since the vertex must be (1,-4) we must check if x=1 satisfies the equation x=-b/2a:

x=-b/2a

1=-(-2)/2(1)

1=2/2

1=1

Both sides are equal to each other, so the final function is g(x) = (x+1)(x-3)

Answer:

∠C = 36

Step-by-step explanation:

2x + 2x +6x = 180

10x = 180

x = 18

∠C = 2x = 36

Answer: 85.2

Step-by-step explanation:

The answer is correct because, to find your grades your bassicaly just looking for the mean. To find the mean you have to take all the numbers and add them after you do that you have to divide how ever much numbers you added. So in this case we do 90 plus 76 plus 88 plus 80 plus 92. That equals 426, and since we added five numbers we divide the answer by 5 and that equals 85.2.

Hope This Helps!

Answer:

Below.

Step-by-step explanation:

As the 2 sides are both cut in half by the horizontal line,  7x-1 = 1/2 * the base line, so:

2(7x - 1) = 48

14x - 2 = 48

14x = 50

x = 50/14

= 25/7.

Answer:

x = [tex]\frac{25}{7}[/tex]

Step-by-step explanation:

A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is

7x - 1 = [tex]\frac{1}{2}[/tex] × 48 = 24 ( add 1 to both sides )

7x = 25 ( divide both sides by 7 )

x = [tex]\frac{25}{7}[/tex]

Where is the diagram???

Answer:

32.9 degrees

Step-by-step explanation:

cos (x) = 21/25

cos^1 (21/25)

= 32.856 --> round to 32.9

Answer:

32.9°

Step-by-step explanation:

You can see that relative to the angle that is x, we are given the side lengths that are adjacent and the hypotenuse. The trig function associated with this is cosine, and we get:

cos(x) = adj / hyp --> 21 / 25

To find x as the angle, we use the function arccosine,

x = arccosine(21/25)

x = 32.85988038°

And this rounds up to 32.9°

Answer:

64

Step-by-step explanation:

add them all up firstly to get 701

then divide by how many are there (11)

then you will get 63.72

and you need to round up since the decimal is a 7

which that gives you 64

Answer:

Option D

Step-by-step explanation:

Given expression has been given as,

[tex]\sqrt[5]{224x^{11}y^8}[/tex]

[tex]\sqrt[5]{224x^{11}y^8}=\sqrt[5]{2\times 2\times 2\times 2\times 2\times 7(x^{11})(y^8)}[/tex]

                 [tex]=\sqrt[5]{(2^5)\times (7)(x^{10}\times x)(y^5\times y^3)}[/tex]

                 [tex]=2^{\frac{5}{5}}\times 7^{\frac{1}{5}}\times x^{\frac{10}{5}}\times x^{\frac{1}{5}}\times y^{\frac{5}{5} }\times y^{\frac{3}{5} }[/tex]

                 [tex]=2\times 7^{\frac{1}{5}}\times x^2\times y\times x^{\frac{1}{5} }\times y^{\frac{3}{5} }[/tex]

                 [tex]=2x^2y\sqrt[5]{7xy^3}[/tex]

Option D will be the answer.

Answer:

A. y ≥ 2x – 2

Step-by-step explanation:

The difference in the height of the two trees is 15 feet

The height of the zip line on both trees is given as:

Height 1 = 25 feet

Height 2 = 10 feet

Calculate the difference in both heights

ΔHeight  = Height 1 - Height 2

This gives

ΔHeight = 25 - 10

ΔHeight = 15

The question cannot be solved further because the horizontal distance between the trees is not given.

Answer:

they look like their curved at about  70? 65? and they would be the same

Step-by-step explanation:

Answer: Both C and D are 76

Step-by-step explanation:

Because this is a isosceles triangle both C and D are the same. Subtract 28 from 180 and you get 152. So D and C combined equals to 152 so divide that by 2 an you get 76.
