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
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.
El triángulo que usamos en las funciones trigonométricas es
Trigonometric functions are commonly defined as the quotient between two sides of a right triangle, associated with its angles. Trigonometric functions are functions whose values are extensions of the trigonometric reason concept in a right triangle plotted in a unit circumference (radius unit).
What are the angles of this shapes?

Answer:
For shape 1, the angle would be 360/8 = 45 degrees
For shape 2, as it doesn't have rotational symmetry, it would just be 360 degrees.

[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 fractionsFrom 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 6/9Dividing both the numerator and denominator by 3, we get
2/3
∴ 6/9 is not equivalent to 4/7
For 8/14Dividing both the numerator and the denominator by 2, we get
4/7
∴ 8/14 is equivalent to 4/7
For 2/3This is the lowest form of this fraction and it is not equivalent to 4/7
For 8/21This 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.

Answer:
Area of original shape: x1
Area of zoomed shaped: x4
Perimeter of original shape: x1
Perimeter of zoomed shaped: x2
Step-by-step explanation:
Since the image is zoomed in by 2, it means that all measurements are doubled. When calculating the area, the zoomed shape had an area 4 times greater than the original shape! With perimeter, instead of the same multiplier, the perimeter of the zoomed shape was only doubled of the original shape.

Answer:
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.

X-2 = 2?
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.

The probability of her catching a trout is 6/25
What is probability ?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
According to the question
based on given condition , formulate
24 ÷ (23 + 12 + 24 + 41)
Calculate sum or difference = 24/23 + 12 + 24 + 41
Calculate sum or difference = 24/59 + 41
Calculate sum or difference = 24/100
Reduce the fraction = 6/25
Hence, the probability of her catching a trout is 6/25
