Complete the following problems.
Amy has $50 in her lunch account. Amy spends $3 a day for lunch. Amy's mother receives a notification when Amy's
account balance reaches $5 or lower. How many lunches can Amy purchase until her mother receives a notification? And what is the equation in slope intercept form

Answers

Answer:

Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.

Step-by-step explanation:

The balance Amy has in her lunch account is a function of the number of lunches she has consumed.

The initial balance is $50 and it decreases by $3 for every lunch Amy has. Thus, the function that models the balance in her lunch account is:

[tex]B(x)=50-3x[/tex]

Where x is the number of lunches.

Her mother receives a notification when the balance goes at $5 or lower, thus the condition that triggers the notification is:

[tex]B(x) \le 5[/tex]

Or, equivalently:

[tex]50-3x\le 5[/tex]

Subtracting 50:

[tex]-3x\le 5-50[/tex]

[tex]-3x\le -45[/tex]

Multiplying by -1 (and flipping the sign):

[tex]3x\ge 45[/tex]

Solving:

[tex]x\ge45/3[/tex]

[tex]x\ge 15[/tex]

Amy can purchase up to 14 lunches until her mother receives the notification. When she has the 15th lunch, the notification will be sent.

Which is the first step in solving
X-2 = 2?

Answers

Answer:

The first step is to find a number that when subtracted from 2 gives you 2.

Step-by-step explanation:

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

first x-2=2, then x-2(+2)=2(+2)  which would give us,

x=4

*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.

Which of the following fractions is 4/7 equivalent to ?

6/9
8/14
2/3
8/21

Answers

Answer:

8/14

Step-by-step explanation:

8/14 simplifies to 4/7.

[tex]\frac{8}{14}=\frac{8/2}{14/2}=\frac{4}{7}[/tex]

Hope this helps.

The fraction that is equivalent to 4/7 among the given set of fractions is 8/14

Equivalent of fractions

From the question, we are to determine the fraction that is equivalent to 4/7

To determine this, we will reduce each of the given fractions to their lowest terms where possible

For 6/9

Dividing both the numerator and denominator by 3, we get

2/3

∴ 6/9 is not equivalent to 4/7

For 8/14

Dividing both the numerator and the denominator by 2, we get

4/7

∴ 8/14 is equivalent to 4/7

For 2/3

This is the lowest form of this fraction and it is not equivalent to 4/7

For 8/21

This is the lowest form of this fraction and it is not equivalent to 4/7

Hence, the fraction that is equivalent to 4/7 among the given set of fractions is 8/14.

D. rectangle

Step-by-step explanation:

The slopes of 2 lines are perpendicular when they are the negative reciprocal of each other. In this case, that is true, because 3 is the negative reciprocal of -1/3 and vice versa. This means it's either a rectangle or a square.

The lengths of the lines are not all the same, meaning it cannot be a square.

Therefore, the best name for the quadrilateral MATH is rectangle.

Answer to The model represents the quotient of two fractions equation does this model represent

A.) 5x-1=-6
B.) 5x=-5 -5/5=-1 so x=-1
The answer is x=-1 because in order to solve the equation, you have to remove the -1, which means you add 1 to each side, because the -6 was negative, when you add 1 it goes to -5, at this point it should look like 5x=-5. Now you divide by 5 on both sides since the coefficient of x is 5, leaving you with the answer, x=-1
