To find x:
Triangles are in total 180 degrees. The two triangles are basically 1 triangle split in half. If the triangle share the same side, has similar angles (shown by the curves on both sides at the top(Angle BAC and CAB), and has similar sides(shown by the hashes made in the lines AC & AB), you can conclude 'x' as a 90 degree angle.
To find y:
The measurment of the angle DCA is 47 degrees. For x, we concluded the answer to be 90 degrees, making the other side of the line 90 degrees as well.Since a triangle is 180 degrees, we can add 47 and 90 to get 137. Taking that answer, we subtract it from the value of 180 degrees to get 43 degrees. So y equals 43.

Answer:

x-int (2, 0)

y-int (0, 3)

General Formulas and Concepts:

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis.

Step-by-step explanation:

Step 1: Locate x-intercept

x-int (2, 0)

Step 2: Locate y-intercept

y-int (0, 3)

Q12.

SVEN [57.7K]

Answer:

Step-by-step explanation:

1l ........8.5 miles

x l .......6 miles

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

x=6*1/8.5

x=0.70 l

2*0.7=1.4 l petrol/day ( to work and come back home)

5*1.4=7 l/week ( 5 days works in a week)

7*1.26=8.82 L /week

8.82>8.5

The petrol costs more

So the answer is NO

How much will it cost to borrow $2,500 for a year at a simple interest rate at 14% please explain

Mariana [72]

Principle (P) = $ 2,500

Rate (R) = 14%

Time (T) = 1 year

Simple Interest (SI) = $\frac{PRT}{100}$

SI = $\frac{2500 * 14 * 1}{100} = \frac{25 *14}{1} = 350$

Hence, the answer is $350.

Multi step equations 4-5x=29

Gemiola [76]

Answer: x = -5

Step-by-step explanation:

1) subtract 4 from both sides (-5x = 25)

2) divide -5 from both sides (x = -5)

Then you have the answer!

What is the greatest common factor of 32 and 48

Bond [772]

Turn each number into the product of it's prime factors.

32=16x2=2x2x2x2x2=2^5

48=24*2=6x4x2=2x3x2x2x2

Pick the highest number that occurs. In this case it is 2. Now we have to see how many times it appears in both. It appears 5 times in 32 and 4 times in 48. 4 is the highest number of times it appears in the numbers so:

2^4=2x2x2x2=16

The Greatest Common Factor (GCF) of 32 and 48 is 16.
