The first one is the correct one. The attendance is 294 on both Play A and B. If you dont believe me, just plug in 30 as x in both equations, and you'll get 294 on both. Hope this helps! :)

11111nata11111 [884]

The two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c

<em><u>Solution:</u></em>

Given that,

Rick buys remote control cars to resell

He applies a markup of 21%

Let "c" be the original price of remote control cars

To find: Expression for retail price of car

We know that,

Retail price = original price + markup

Here, markup price = 21 % of original price

Markup price = 21 % of c

Therefore, substituting the given values we get,

Retail price = c + 21 % of c

$\text{ Retail price } = c + 21 \% \times c\\\\\text{ Retail price } = c + \frac{21}{100} \times c\\\\\text{ Retail price } = c + 0.21c\\\\$

This can also be expressed as,

$\text{ Retail price } = c + 0.21c = 1.21c$

Thus two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c

Divide the following fractions and reduce to lowest terms 2/3 divided by 4/5

pshichka [43]

Well to divide 2 fraction you first have to find a least common number between the 2 bottom numbers in the fractions, we know automaticall that 15 fits in both the 3 and the 5. now u have to find out what to multiply by each number to get 15, for example what number do you multiply by 3 to get 15?? well it will be 5, so go ahead and multiply it by the fraction (note that what you do in the bottom you have to do in the top) this will give you 10/15, because I multiplied the top and bottom number by 5... lets try the other one what number do you multiply by 5 to get 15?? well it will be 3 so go ahead and multiply that to get 12/15.. now add the top numbers (note that the bottoms always stay the same, you never add or subtract them) when you do you will get 22/15, now you have to see if you can simplify it any further in this case you can't so your final answer is 22/15

Hope this helps

Jack is trying to figure out a rule for this table. He comes to the conclusion that the rule is f(x)= 3x. Why is Jack's rule inc

Olegator [25]

He is incorrect because if a number is before a letter than the number is the coefficient. and the coefficient is always multiplied by the letter its next to. since f is being distributed to x (multiplied because of the parentheses) then fx=3x which means f = 3 which means 3x=3x

Answer:

y = 1/2 x + -5

Step-by-step explanation:

Slope-intercept form is y = mx + b

where m is the slope and b is the y-intercept

m is equal to change in y/ change in x ( aka horizontal change over vertical change), in the graph the horizontal change is 1 up for every 2 units right, which equals 1/2

b is the y-intercept (when x=0), if you look at the graph x=0 when y=-5

Lastly, you put in m and b into the equation to get y = 1/2 x + -5
