Evaluate the expression when c= -4 and y= 3 c-5y
Dmitry_Shevchenko [17]

Answer:

-19

Step-by-step explanation:

If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: <em>(-4) - (5 * 3).</em>

Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.

Now the expression is <em>(-4) - (15).</em> Then, you do the subtraction. -4 - 15 is equal to -19.

Does that help?

(V+5)9 use distributive property to remove parentheses
mina [271]
Hello there!

The Distributive Property allows us to multiply the number outside of the parenthesis by all inside numbers.

An example;

2(3 + 4)
2(3) + 2(4)
6 + 8
14.

Let's apply this to our current expression.

9(V + 5)
9(v) + 9(5)
9v + 45 is your expression.

I hope this helps!

Please help this is my last question and I've been waiting 40 minutes

Check the picture below.

now, notice, each square in the grid is 2 units, so, x = 8, y = 10 and x = 13, y = 5

\bf slope = {{ m}}= \cfrac{rise}{run} \implies &#10;\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby &#10;\begin{array}{llll}&#10;average\ rate\\&#10;of\ change&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;\qquad &#10;\begin{cases}&#10;x_1=8\\&#10;x_2=13&#10;\end{cases}\implies \cfrac{f(13)-f(8)}{13-8}\implies \cfrac{5-10}{13-8}\implies \cfrac{-5}{5}\implies -1

-1 or -1/1, or -(vertical distance) / (horizontal distance)

the negative means is dropping, and 1/1 means, for every foot going down, it moves farther away from the kicker by 1 foot.

Abby is adopting kittens from the pet store. if there are 18 kittens, how many ways can she choose 2 kittens? **the answer isnt
Arturiano [62]

Answer:

153 ways.

Step-by-step explanation:

The answer is the number of combinations of 2 from 18

= 18! / 2! (18-2)!

= 18! / 2! 16!

= 18*17*16! / 2! 16!

= 18 * 17 / 2*1

= 9 * 17

= 153 ways.
