QUESTION POSTED AT 10/10/2019 - 07:33 PM

Pick 2 exact points on the line, then use the slope formula to get your answer.

(3,0) , (0,-3)

m = slope

m = y₂-y₁ / x₂-x₁

Plug in the numbers.

m = -3-0 / 0-3

Simplify.

m = -3 / -3

m = 1

So, your slope is 1

**Answer:**

Lets say that you're bisecting segment AB.

**Step-by-step explanation:**

1. Place the compass on point A, and open it wider than half the distance of the segment.

2. Swing an arc above and below the segment.

3. Keeping the compass the same width, place the compass on point B, and swing an arc above and below the segment.

4. Place points C and D on the intersection of the arcs created above and below segment AB.

5. Draw a line from point C to point D.

Basically, we need to isolate y

Assuming 0 is unnecessary:

x + 19y = 38

19y = -x + 38

Assuming that 0 is necessary:

0x+19y = 38

0•x is equivalent to 0 so that cancels out x leaving us with

19y = 38

y = 38/19

y = 2

If the 0 is necessary, your answer is**y = 2**.

If the 0 is unnecessary, your answer is**y = -(x/19)+2**

Assuming 0 is unnecessary:

x + 19y = 38

19y = -x + 38

Assuming that 0 is necessary:

0x+19y = 38

0•x is equivalent to 0 so that cancels out x leaving us with

19y = 38

y = 38/19

y = 2

Part1

there are 360° in a circle (clock), and thus if we check how many degrees in a clock with 60minutes, then it'd be 360/60, or 6° per minute

now, the clock went from 3:35 to 3:55, 20 minutes, how many degree is that? 6*20

The shaded region is the area of the circle minus the area

of the pentagon.

A circle = pi * r^2

A circle = pi * 15^2

A circle = 706.5 cm^2

A regular pentagon = (a * p)/2 where a is the apothem, p is the perimeter.

The apothem id the perpendicular height from the midpoint of a side to the center of the pentagon.

To find the apothem you have to use a trig ratio.

A pent = (8.3 * 12*5)/2

A pent = 249 cm^2

Shaded region: circle - pentagon 706.5 - 249 = 457.5

of the pentagon.

**Answer:**

The midpoints of the EF is (2a,a) .

**Step-by-step explanation:**

Definition of midpoints.

The midpoint is the point lie in middle of a line segment. It is equidistant from both endpoints .

Formula

Quadrilateral EFGH has coordinates E(a, a), F(3a, a), G(2a, 0), and H(0, 0).

Now find out the midpoints of the E(a, a) and F(3a, a) .

Midpoints of EF = (2a,a)

Therefore the midpoints of the EF is (2a,a) .

This is the concept of probability and statistics, we are required to calculate the probability of getting a red, blue and black respectively, given that there are 3 red, 8 blue and 7 black beads;

Probability of an event occurring=(Number of ways it can occur)/(Total number of outcomes )

The total number of outcome in our situation is:

3+8+7=18

P(Red)=3/18=1/6

P(Blue)=8/17

P(Black)=7/16

since these occurrence are such that the selection is without replacement, that means they are dependent. The probability of them occurring in that order will be:

P(x)=1/6*8/17*7/16=7/204

The answer is d. dependent; 7/204

- Both pairs of opposite angles in an isosceles trapezoid are supplementary which means their sum add up to 180°.

**Therefore; **

**∠ B + ∠ A = 180° and ∠T + ∠O = 180°**

**Hence; ∠O = 180 -∠T**
