Answer:

(A) and (C)

Step-by-step explanation:

Slope is defined as The slope is a measure of the steepness of a line, or a section of a line, connecting two points.

consider two points (x_{1},x_{2}) and (y_{1},y_{2}), then the slope formula is given as "rise over run", because the fraction consists of the "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).

Also, the slope formula is given as:

Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Hence, the correct statements are:

(A) statement A and (C) statement C

I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coin
Alenkinab [10]

Answer:

(35k + 20) cents

Step-by-step explanation:

First of all, let us have the value of each unit:

1 quarter = 25 cents

1 nickel = 5 cents

1 dime = 10 cents

Given that number of quarter = k

Quarters are 5 lesser than Nickels, so number of nickels = k+5

One more than twice as many dimes as quarters:

k = 2 \times Number of Dimes + 1

So, number of dimes = \frac{1}{2}(k-1)

Value of quarters = 25 \times k cents

Value of nickels = 5 \times (k+5) = (5k+25)\ cents

Value of dimes = \frac{1}{2}(k-1) \times 10 = (5k-5)\ cents

So, total value of coins =

25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents

Use the elimination to solve this equation. <br><br> 2x+3y=55 <br> 9x+4y=105
seropon [69]
X=5 y=15 (5,15). 
This is how you do it:
-4(2x+3y=55): -8x-12y=-220
3(9x+4y=105):27x+12y=315

You add the two new equations together, canceling out the y values, and get the x value. Then, you go back and plug in the x value in the original equation to get the y value.
