The slope is 2

Step-by-step explanation:

Pick two points.

ex: (0,-1) and (2,3)

do the equation below where 0=x1, -1=y1, 2=x2, 3=y2

y2-y1 divided by x2-x1

3-(-1) divided by 2-0

sorry this was kind of hard to explain on a computer :/

Answer:

632 square feet

Step-by-step explanation:

Surface area of the prism = 2(lw+wh+lh)

L is the length = 12feet

w is the width = 8feet

h is the height = 11feet

Substitute

S = 2(12*8 + 12*11 + 8*11)

S = 2(96+132+88)

S = 2(316)

S = 632 square feet

Hence the surface are of the prism is  632 square feet

Answer:

Ok if you get this worng im so sorry but I got $6.21

Step-by-step explanation:

Answer:

10 feet = 120 inches

120 / 7 = 17.1428571429

So, the scale is 17.1428571429 to 1.

Answer:

(7,8)

Step-by-step explanation:

The point D is (7, 8) for which the given coordinates of A(3, 6), B(5, 2), and C(9, 4), make a square.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.

Line AB and CD are parallel to each other.

Line AB:

(y- 6) = -2(x-3)

y - 6 = -2x+6

2x+y = 12

Line CD:

2x + y = d

Plug (9,4)

18+4 = d

d = 22

2x + y = 22 ...(1)

Line BC:

(y - 2) = 1/2(x-5)

2y -4 = x-5

-x + 2y = -1

x - 2y = 1

Line AD:

x - 2y = e

3 - 12 = e

e = -9

x-2y = -9 ...(2)

The intersection point of (1) and (2)

x = 7 and y = 8

Thus, the point D is (7, 8) for which the given coordinates of A(3, 6), B(5, 2), and C(9, 4), make a square.

Answer:

the second one

Step-by-step explanation:

Hello There!

The area of a triangle can be found using this formula

[tex]A = \frac{1}{2} (a+b)h[/tex]

where a and b = bases and h = height

The trapezoid shown has the following dimensions

top base = 9cm

bottom base = 14 cm

height = 12 cm

slant height = 13 cm

using this information, we plug in the values into the formula

So [tex]A = \frac{1}{2} (9+14)12[/tex]

the equation we created matches the 2nd equation therefore the second one is your answer

A circle is a curve sketched out by a point moving in a plane. The area of the circular paper is more than the area of the square.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The arc length of radius 6 inches is equal to,

Length of the Arc of a quarter = 2πr×(1/4) = 2×π×6×0.25 =0.9448 inches

The area of the circular paper = πr² = π×6×6 = 113.097²

The area of the square with a side of 6 inches = 36 in²

Therefore, the area of the circular paper is more than the area of the square.

Answer: 17.75p + 8 ≤ 150    OR    p ≤ 8

Step-by-step explanation:

(0, 0) is a solution to the equation y = 9x

Given the equation y = 9x, we are to determine whether (0, 0) is a solution to the equation

To do that, we will substitute x = 0 into the expression and determine if the value of y is 0.

If x = 0

y = 9x

y = 9(0)

y = 0

Since the resulting value of y is zero, hence (0, 0) is a solution to the equation y = 9x

Answer:

filled in dot on -2 and shade the rest to the right (see below)

Step-by-step explanation:

This can also be read as "x is equal to or greater than -2." The "alligator" mouth, aka the inequality sign, is "eating" the x, meaning it's greater than the -2.

First graph the -2. Because it's also equal to, the dot on the -2 is filled in.

The inequality also acts as an arrow. It's pointing to the right, so the rest of the number line to the right is shaded.

This arrow method works only when the variable is on the left side so that is read "x is greater/less than a number."
