The written and solved equation to determine the cost of the desserts, d is 5(9.75 + d) = 63.75; d = 3.00
How to solve an equations?Five friends ate lunch and spent a total of $63.75.
They each bought the same meal for $9.75, and they each bought the same dessert.
The equation to determine the cost of the dessert, d can be represented as follows:
Hence,
5 (9.75 + d) = 63.75
48.75 + 5d = 63.75
Therefore, let's use the equation to solve for d.
48.75 + 5d = 63.75
subtract 48.75 from both sides of the equation
63.75 - 48.75 = 5d
15 = 5d
divide both sides of the equation by 5
15 / 5 = 5d / 5
d = 3

The functions f and g are defined as follows.
f (x) = -2x^3 - 3 g (x) = 2x + 4
Find f (-2) and g (-6).
Simplify your answers as much as possible.
If the function are f(x) = [tex]-2x^{3}-3[/tex] and g(x)= 2x+4, then the values of
f(-2) = 13
g(-6) = -8
The functions are
f(x) = [tex]-2x^{3}-3[/tex]
g(x) = 2x+4
The function is an expression that represents the relationship between one variable and another variable. if one variable is independent variable another variable will be dependent variable.
First we have to find the value of f(-2)
Substitute the value of x= -2 in the given function
f(-2) = [tex]-2(-2)^3-3[/tex]
= -2×-8-3
= 16-3
= 13
Next we have to find the value of g(-6)
Substitute the value of x= -6 in the given function
g(-6) = 2×-6+4
= -12+4
= -8
Hence, if the function are f(x) = [tex]-2x^{3}-3[/tex] and g(x)= 2x+4 then the values of
f(-2) = 13
g(-6) = -8

Which inequality is represented by the number line below?
The inequality that is represented by the number line is C. x ≤ 7.
What is an inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The most frequent application is to size-compare two numbers on a number line. A difference between two values indicates whether one is smaller, larger, or simply not equal to the other.
It should be noted that from the number line, we can see that the arrow starts from -7 and then moves backwards. This shows that it's x ≤ 7.

4/5 is the probability that jack will win at least 30 points in a throw.
What do we mean by probability?The probability is the likelihood that something will happen, to put it simply.The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out.The study of events that fit into a probability distribution is known as statistics.The probability is determined by dividing the total number of outcomes by the total number of potential events.Odds and probability are two different concepts.Calculating odds involves dividing the probability of an event by the probability that it won't happen.So, the probability formula:
P = favourable events/Total number of eventsFavorable events: (At least 30 points) ⇒ 30 + 40 + 50Total events: (Sum of all points) ⇒ 150Now, insert values in the formula as follows:
P = favourable events/Total number of eventsP = 120/150P = 12/15P = 4/5Therefore, 4/5 is the probability that jack will win at least 30 points in a throw.

Harlan is preparing a dip for a party the recipe calls for 4 cups of sour cream and three packages of onion soup mix he doesn’t want to prepare that my street decides to use only 2 cups of sour cream and one and a half packages of onion soup mix is this a proportional relationship
Yes!, This is a proportional relationship.
A proportional relationship means that the ratios of two variables are equal.
According to the question, the requirements of the recipe are
Number of cups of sour cream required be x1 = 4
Number of packages of onion soup mix required be y1 = 3
Used products by Harlan,
Cups used by Harlan of sour cream be x2 = 2
Packages of onion soup mix used by Harlan be y2 = 1.5
As we can see that,
x1/x2 = y1/y2
4/2 = 3/1.5
2 = 2
L.H.S = R.H.S ( ratio is same)
Therefore, we conclude that the above case is a proportional relationship.

You invested $28,000 in two accounts paying 3% and 6% annual interest, respectively. If the total interest earned for
the year was $1590, how much was invested at each rate?
The amount invested at 3% is $
The mount invested at 6% is $
Answer: 6000 at 3% and 22000 at 6%
Step-by-step explanation:
x + y = 28,000
0.3x + 0.6y = 1500
multiply everything in the first equation by 0.3 since we want to be able to eliminate the variable x from both equations.
0.3x +0.3y = 840 then subtract second equation to just get one variable
0.3x + 0.6y =1500
-0.3y = -660
y = 22000
28000 - 22000 = 6000 which is x
So 6000 is invested at 3% and 22000 is at invested at 6%
