Answer:

y = 3x - 9

Step-by-step explanation:

First, find the slope using y2 - y1 / x2 - x1

36 - 21 = 15

15 - 10 = 5

15/5 = 3, so the slope (m) is 3.

Now, plug into point-slope form: y - y1 = m (x - x1)

y - 21 = 3 (x - 10)

Simplify

y - 21 = 3x - 30

y = 3x - 9

I hope this helps!!

Line AB is parallel to line CD. What is the measure of angle CFE?
Art [367]

Answer: c

Step-by-step explanation:

A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe

180-55=125

Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90

Can't be 180 because the whole thing equals 180

Help, please! ASAP!!​
In-s [12.5K]

Answer:

a) one solution

b) no solution

Step-by-step explanation:

Systems of equations can be described as having one solution, no solution or infinite solutions:

One solution:  'x' and 'y' are equal to only one value

No solution:  'x' and 'y' can not be solved with the given equations

Infinite solutions:  values for 'x' and 'y' include all real numbers

In order to evaluate the systems, putting them in the same format is your first step:

a) - y  = -5x - 6 or y - 5x = 6

   y - 5x = -6

Since both equations have the same expression 'y - 5x', but there are equal to opposite values, this system would have no solution, as this would not be possible to calculate.

b) y + 3x = -1

  y = 3x -1 or y - 3x = -1

Solving for 'y' by adding the equations and eliminating 'x', gives us:

2y = -2 or y = -1

Using y = -1 to plug back into an equation and solve for 'x':  -1 + 3x = -1 or x = 0.  Since 'x' and 'y' can be solved for a value, the system has just one solution.

Which one is the answer??
BARSIC [14]

Answer:

B

Step-by-step explanation:

City X = 3 * 10^5            Given

City Y = 6 * 10^6

Times larger

6 * 10^6

3 * 10^5

Do the division

6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5)   Note 10^5 will cancel

60/3 = 20 City y is 20 times City x

Population Difference

6,000,000

   300,000

5,700,000

Just from the numbers I've given you, A is incorrect. The answer is 20 not 2.

B is the answer

C is wrong. X is 5.7 million less.

D See the answer for C.

While walking in her neighborhood, Ashley found 3 dimes and 4 pennies on the ground. What percent of a dollar did Ashley find?
faltersainse [42]

Answer:

34%

Step-by-step explanation:

Dime = 10 cents, 10% of a dollar

Penny = 1 cent, 1% of a dollar

3 dimes = 30% of a dollar

4 pennies = 4% of a dollar

30% + 4% = 34%
