A pet store owner, Byron, needs to determine how much food he needs to feed the animals. Byron knows that he needs to order the same amount of bird food as hamster food. He needs four times as much dog food as bird food and needs half the amount of cat food as dog food. If Byron orders 600 packages of animal food, how much dog food does he buy? Let b represent the number of packages of bird food Byron purchased for the pet store.

Answers

Answer:

300 bags of dog food

Step-by-step explanation:

4b + 2b + b + b = 600

(dog) + (cat) + (bird) + (hamster) = 600

8b = 600

b = 75

Byron purchased 75 bags of bird food. He needs 4 times that of dog food. So, he purchased 300 bags of dog food.

The Johnson and Sloan families went to Taco Mania for lunch. The Johnsons bought 3 burrito meals and 4 taco meals for $48. The Sloans bought 6 burrito meals and 2 taco meals for $60. How much does each meal cost?

Answers

Answer:

Each burrito meal cost 8$

Each taco meal cost 6$

Step-by-step explanation:

Johnsons= 3b +4t =48

Sloans= 6b+2t=60

multiple johnsons by -2

so, now the johnsons are -6b+-8t=-96

add that to the sloans so, -6b+6b-8t+2t=-96+60

the b's cancel eachother out, so you are left with -6t= -36

divide each side by -6 and you will get t=6

then you can pick either formula, lets say sloans this time

so, 6b + 2(6)=60 so, 6b+12=60, subtract 12 from each side, to get 48

so 6b=48, divde each side by 6 and you will get b=8

Step-by-step explanation:

Answer:

Tacos-6

Burritos-8

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(3b+4t=48)

1(6b+2t=60)

Becomes:

−6b−8t=−96

6b+2t=60

Add these equations to eliminate b:

−6t=−36

Then solve−6t=−36for t:

−6t=−36

−6t

−6

=

−36

−6

(Divide both sides by -6)

t=6

Now that we've found t let's plug it back in to solve for b.

Write down an original equation:

3b+4t=48

Substitute6fortin3b+4t=48:

3b+(4)(6)=48

3b+24=48(Simplify both sides of the equation)

3b+24+−24=48+−24(Add -24 to both sides)

3b=24

3b

3

=

24

3

(Divide both sides by 3)

b=8

Answer:

b=8 and t=6

f(x) = 2(x + 3)^2 – 6
Find the standard form and the y intercept. Please

Answers

Answer:

f(x) = 2x² + 12x + 12; y-intercept is 12

Step-by-step explanation:

f(x) = 2(x + 3)² - 6

This equation is in point slope form. We want to put it in standard form.

According to PEMDAS (parentheses/exponents | multiplication/division | addition/ subtraction), we should solve the exponent first. (the expression in the parentheses is as simplified as possible).

(x + 3)² → (x +3)(x + 3)

To solve this, we need to FOIL (first | outer | inner | last)

F: x²

O: 3x

I: 3x

L: 9

Combine these terms.

x² + 3x + 3x + 9

x² + 6x + 9

Plug this expression back into your original equation.

f(x) = 2(x + 3)² – 6 → f(x) = 2(x² + 6x + 9) - 6

Next, we will distribute the 2 across the parentheses.

f(x) = 2x² + 12x + 18 - 6

Then, combine like terms. (18 & 6)

f(x) = 2x² + 12x + 12

This is your equation in standard form.

Now we want to find the y-intercept. The y-intercept is the y-value when x = 0. Therefore, we need to plug in x = 0 to the equation.

f(x) = 2x² + 12x + 12

f(x) = 2(0)² + 12(0) + 12

Follow PEMDAS again.

[exponents] → f(x) = 2(0) + 12(0) + 12

[multiplication] → f(x) = 0 + 0 + 12

[addition] → f(x) = 12

Your y-intercept is 12.

Hope this helps!

My grandfather sells,sell antiques 2. A Good Day for a Bad DecisionHave you ever noticed that some people always seem to make the right choices? They may be the person who always picks the right pitch to swing at, or the one who always picks the pair of shoes that quickly become a popular fad. On the other hand, some people never seem to make a good decision. They may be the kids who ride a bike down a steep hill and crash into a bush or the ones who step to the edge of a sidewalk in time to get splashed by a car. How do some always seem to be living the good life while others seem doomed to misery? Is this just a matter of luck?While luck probably has something do with it, the better explanation may be that the two groups have differences in the development of their brains. You see, most adult humans use their cerebral cortex to make decisions. The cerebral cortex is the part of the brain in the front of your head that deals with how you perceive the world and respond appropriately. It also helps you control your impulses. This part of the brain is still growing and developing connections well into your adult years. So for young adults and teenagers, the decision-making center of the brain is not completely formed yet.At the same time, the teenage brain is also experiencing growth in another part of the brainthe amygdala (a-mig-dala). This part of the brain is responsible for emotions. Specifically, the amygdala talks to other parts of the brain about events related to rewards and fear.In essence, our emotional brains are having growing spurts and our impulses are out of control at the same time our cerebral cortexes are not finished growing. We simply don't have the tools to control those emotions and impulses. As a result, teenagers feel overly emotional and wishy-washy when it comes to decisions. This development cycle is one reason society doesn't consider children to be adults until after they are 18. Biologically, the teenage brain is not generally ready for adult decisions.So the differences between those who seem to make good decisions and those who seem to make bad ones may be fewer than you think. In fact, if you study the people you think make only good decisions, you will likely find they also make some catastrophically bad ones as well. A person's ability to make a good decision increases with age and experience though we all develop at different rates. While you are young, you may want to take advantage of those around you with bigger cerebral cortexes: adults. Their advice may be just what is needed to counter your amygdala.Which line from the text best states the main idea of the text?
