Answer:

  1. line b is perpendicular to the other two, which are parallel

  2. line a is perpendicular to the other two, which are parallel

Step-by-step explanation:

1. The differences between coordinates (∆x, ∆y) are ...

  (-2, 3) -(1, -1) = (-3, 4) . . . line a

  (-3, 1) -(1, 4) = (-4, -3) . . . line b

  (0, 2) -(3, -2) = (-3, 4) . . . line c

When the (∆x, ∆y) values are identical, the lines are parallel. If the values are swapped, and one differs in sign, the lines are perpendicular.

  line b is perpendicular to lines a and b, which are parallel

__

2. When all of the equations are written in standard form, they are ...

As above, when the x- and y-coefficients are identical, the lines are parallel. If they are swapped and one is negated, the lines are perpendicular.

  line a is perpendicular to lines b and c, which are parallel

__

In the attached graph, the lines of part 1 are blue; those of part 2 are red.

Answer:

8. 504ft²

9. 4970yd² (rounded to 3 s.f.)  

Formulas (For easy reference):

Area of rectangle = length × breadth

Area of circle = pi×r×r

Circumference of circle = pi×r×2

-----------------------------------------------------------------------------------------------------------

Step-by-step explanation:

8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):

(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120

                                                   = 504ft²

9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).

2 Circles = 2×pi×24×24

                = 1152pi

Long sheet = 9×24×2×pi

                   = 432pi

Now we can add all of them together:

432pi+1152pi = 1584pi

                      = 4970yd² (rounded to 3 s.f.)

Answer:

Step-by-step explanation:

9.) Surface Area of Cylinders: A=2πrh+2πr^2

A=2πrh+2πr^2

A=2(3.14)(12)(9)+2(3.14)(12)^2

A = 678.24 + 904.32

A ≈ 1582.56

Answer:

x=1

Step-by-step explanation:

for y²=4ax

directrix is x=-a

for y²=4x ,directrix is x=-1

for y²=4(x-2), shift directrix 2 units right.

so directrix is x=-1+2=1

so for (y+4)²=4(x-2) directrix is x=1

Answer:

PB = 15

Step-by-step explanation:

A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.

Answer:

3 batches

Step-by-step explanation:

We have been given that a sports drink recipe calls for 5/3 tablespoons of powered drink mix for every 12 ounces of water.

We need to find out how many batches can be made with 5 tablespoons of drink mix and 36 ounces of water.

So, from the given information we see that to make 1 batch of sports drink we need 5/3 tablespoons of powdered drink mix for every 12 ounces of water.

So, we have 36 ounces of water. But we know that for 1 batch of sports drink we need to 12 ounces. So with 36 ounces of water we can make

= 3 batches

Therefore, we can make 3 batches of sports drink from 5 tablespoons of powdered drink mix and 36 ounces of water.

x=8

y= -6

Step-by-step explanation:

3(0)-4y=24

-4y=24

24÷-4

y = -6

----------------------

3x-4(0)=24

3x=24

24÷3

x = 8

to find the x-intercept, substitute the y for a zero "0", to find the y-intercept, substitute the x for a zero "0"

Answer:

20 percent

Step-by-step explanation:

Because there are 160 total people, you would divide 32 by 160 which gives you 0.2 multiply 0.2 by 100 then you get 20 percent

32/160 = 0.2

0.2*100 = 20

Answer:

53.3%

Step-by-step explanation:

(32/63)×100

=53.3%

The range of lengths the third piece of wood would be  3 < x < 37 .

Using triangle inequality theorems,  which states that the sum of two side lengths of a triangle is always greater than the third side.

Therefore,

A triangle with sides x, y  and z will be as follows;

x + y > z

x + z > y

y + z > x

Therefore, for the woods to form a triangular piece. The third length will be in the range 4 inches to 36 inches.  

Let's text the rules for the end points

20 inches + 17 inches > 4 inches

20 inches + 4 inches  > 17 inches

17 inches + 4 inches > 20 inches

20 inches + 17 inches > 36 inches

20 inches + 36 inches > 17 inches

17 inches + 36 inches > 20 inches

Therefore, the range of length for the third piece of wood  would be  

3 < x < 37

Answer: In 36 minutes both buses  will end up at the library.

Step-by-step explanation:

Given: Buses from one route stop at the library every 9 minutes.

Buses from the other route stop at the library every 12 minutes.

The number of minutes in which both buses will end up at the library= LCM(9,12)

Now , 9= 3 x 3

12= 2 x 2 x 3

LCM(9,12) = 2 x 2 x 3 x 3 = 36

In 36 minutes both buses  will end up at the library.

Answer:

y= 3x+62

Step-by-step explanation:

m= y₂-y₁/x₂-x₁

m= 80-62/6-0

m= 18/6

m=3

y-y₁=m(x-x₁)

y-62= 3(x-0)

y-62= 3x-0

y= 3x+62

Answer:

Second choice, 4/3

Step-by-step explanation:

With the two point already highlighted, find the difference they have in x and y.  (-1, 2) and (2, 2)

x = -1 - 2 = -3

y = -2 - 2 = -4

The slope is y/x so it would be -4/-3 or just 4/3 because the negatives cancel each other out and they mean the same anyway.

An easier way would to just draw a slope triangle from the two points and count the squares they have. 4 squares going up and 3 squares going to the right = 4/3
