what happens to the graph when a zero is repeated vs when a zero is not repeated? Use y=(x-3)^2 and y=x-3 to explain.

1.- En la cooperativa escolar se vendieron 296 refrescos en total. Si los refrescos chicos vendidos fueron el triple de los

Allisa [31]

Answer:

222 small ones and 74 middle ones

Step-by-step explanation:

The computation is shown below:

Let us assume medium ones be x

so the small ones be 3x

And, the total is 296

So, the equation is

x + 3 x = 296

4x = 296

Medium ones = x = 74

And, the small ones is = 3 × 74

= 222

kherson [118]

Answer:

$48

Step-by-step explanation:

Ashton is saving money for a new bike. He needs 120$ But only has saved 60% so far. How much more money does he need to buy the scooter

Ashton needs money for new bike=120$

savings of ashton is 60 % of his bike cost

hence 60% of 120 dollar will be

His saving=(60/100)*120=7200/100=72$

remaining cost will be obtained by subtracting saved money from total cost

total cost=120 dollar

saved money=72dollar

hence

Remaining more money he needed is =120-72=48$

aksik [14]

Answer:

As x increases, y decreases and then increases

Step-by-step explanation:

You need only understand your own description of the graph:

begins above the x-axis, extends below the x-axis, and ascends above the x-axis

This is a description of <em>decreasing</em>, then <em>increasing</em>:

As x increases, y decreases and then increases

One year there was a total of 59 commercial and noncommercial orbital launches worldwide. In addition, the number of noncommerci

Lina20 [59]

Answer:

The number of commercial orbital launches is equal to 19 and the number of noncommercial orbital launches is equal to 40.

Step-by-step explanation:

IMPORTANT INFORMATION: The number of noncommercial orbital launches was two more than twice the number of commercial orbital launches.

Let's say that the number of commercial orbital launches is equal to x. Now, the number of noncommercial orbital launches is equal to 2x+2.

We are told that if we add the number of commercial and noncommercial orbital launches together we will get 59.

Therefore, if we add 2x+2 with x we should get 59:

2x+2+x=59

3x+2=59

3x=57

x=19

This is how we can come to the answer that the number of commercial orbital launches is equal to 19 and the number of noncommercial orbital launches is equal to 40 (2x+2=2*19+2=38+2=40).

Hope this helps!

The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on

hoa [83]

<h3><u>Question</u></h3>

The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?

<h3><u>Answer:</u></h3>

Charlie saved $ 28

<h3><u>Solution:</u></h3>

Given that amount of money that Charlie saves each week is directly proportional to the amount he earns

Let y represent of saved money and x represent amount of earned money

Therefore,

$\text{ Amount of money saved each week } $\propto$ amount he earns$

$y \propto x$

y = kx --- eqn 1

Where "k" is the constant of proportionality

<em><u>Last week Charlie saved $32 on his earnings of $512</u></em>

y = 32 and x = 512

Substituting in eqn 1, we get

$32 = k(512)\\\\k = \frac{32}{512} = 0.0625$

To find amount of saved money, we will substitute k = 0.0625 and x = 448 in eqn 1

y = 0.0625(448) = 28

Thus charlie saved $ 28
