I’m having trouble finding angle DCE, I figured out the angles in the kite (I hope), how do I find the angle next to it, it does

n’t equal 180, does it?

Answer:

180 -angle BCD

Step-by-step explanation:

if you've found angle BCD you should be able to find angle DCE as angles on a straight line equal 180°

two runners start 30kilometer apart and run toward each other. they meet after 3hours. One Runner runs 2 kilometers per hour fas
belka [17]

Let the slower runners speed be X kilometers per hour.

Then the faster runners speed would be X+2 kilometers per hour.


The formula for distance is Speed times time.

The distance is given as 30 kilometers and time is given as 3 hours.


Since there are two runners you need to add the both of them together.

The equation becomes 30 = 3x + 3(x+2)

Now solve for x:

30 = 3x + 3(x+2)

Simplify:

30 = 3x + 3x +6

30 = 6x + 6

Subtract 6 from each side:

24 = 6x

Divide both sides by 6:

x = 24/6

x = 4


The slower runner ran at 4 kilometers per hour.

The faster runner ran at 4+2 = 6 kilometers per hour.

The width of a rectangle is 5 feet shorter than its length. If the area of the rectangle is 24 square feet, find the dimensions
Amiraneli [1.4K]

Lets look at the possible factors of 24. 24*1, 12*2, 8*3, and 6*4. Only 8 and 3 have a difference of 5, so the rectangle has the dimentions of 8 by 3.

Whats the best answer for this ???
Romashka-Z-Leto [24]
Just simplify the given equation
y = 7.2 + 4(x-2)
y = 7.2 + 4x - 8
y = 4x - 0.8

Now they want to know the answer if X = 2
y = 4(2) - 0.8
y = 8 - 0.8
y = 7.2

Mr. shaw graphs the function f(x) = –5x 2 for his class. the line contains the point (-2, 12). what is the point-slope form of t
True [87]

y - 12 = -5(x + 12) is the required equation.

f(x) = -5x + 2

let f(x) = y

y = -5x + 2

y = -5x + 2

comparing it to y = mx + c

m = -5

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The equation of a line is an equation that is satisfied by each and every point on the line. This means that a linear equation in two variables represents a line.

The point slope equation formula is

y - y₁ = m(x - x₁)

Now the equation of line containing (-2,12) is

y - {y}_1= m(x - {x}_1)\\

y - 12 = -5(x + 12)
