What's the correct formula for this function?
Answer:
Option C. y = -2x + 3
Step-by-step explanation:
When we look at this function we see that it has a negative slope and the y-intercept is equal to (0,3). From this we know that the function we are looking for will be looking like...
y = mx + 3
And as I said earlier since the slope is negative, the only right option is this case will be Option C
Answer:
The correct anwer is (C) : y = - 2x + 3
A jar contains n nickels and d dimes. There are 22 coins in the jar and a total value of the coins is $1.50. How many nickels and how many dimes are in the jar?

23.5
Answer:
12 nickels. 9 dimes
Step-by-step explanation:
12 nickels is equal to 60 cents
9 dimes equals 90 cents
90 plus 60 equals 150 which is $1.50

Which graph shows only the solutions of the inequality that makes sense for this situation?
Answer:
its on the bottom of the first answer the third one
Step-by-step explanation:
The First graph shows only the solutions to the inequality that makes sense for this situation.
What is Inequality?
Relation between two mathematical identities which is not equal that is it can be either greater than or less than or greater and equals to or less and equals to etc, is called Inequality.
In the given problem the variable is the number of cars.
Let us assume that the variable c represents the variable quantity which is the number of cars for the inequality.
Now we know that number of cars is always a positive and whole number.
So the suitable inequality to represent the condition that the number of cars is not more than 7 that is less than or equals to 7 is,
[tex]c \leq 7[/tex]
So the solutions are c=0,1,2,3,4,5,6,7
Hence the first graph shows the correct solution for the given inequality condition.

The most common IQ tests have a standardized mean of 100 and a standard deviation of 15. Based on this information, use the empirical rule to answer the following question: If approximately 348 prospective college students are tested for their IQ, approximately what percentage of their scores will fall within one standard deviation of the mean
Answer:
Approximately 68% of their scores will fall within one standard deviation of the mean.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
By the Empirical Rule, approximately 68% of their scores will fall within one standard deviation of the mean.
A square and a rectangle have equal area.The rectangle is 64 cm by 81 cm. What is the perimeter of the square?
Answer:
2592 cm
Step-by-step explanation:
square area = x²
rectangle area = bh
so
x² = bh
since the areas are equal
b and h are in the problem as 64 and 81
x² = 64x81
x² = 5184
divide by 2
x = 2592 cm

An engineer makes a model of a bridge using a scale of 0.5 cm = 3 feet. The length of the actual bridge is 123 feet. What is the length of the model?
Answer:
20.5 cm
Step-by-step explanation:
Set up a proportion where x is the length of the model in cm:
[tex]\frac{0.5}{3}[/tex] = [tex]\frac{x}{123}[/tex]
Cross multiply and solve for x:
3x = 61.5
x = 20.5
So, the model's length is 20.5 cm
f (x)= 1/x-4 -6. Find the inverse of f(x) and its domain.
Answer:
B Or D
Step-by-step explanation:
The inverse function is [tex]f^{-1}(x) = \frac{1}{x + 6} + 4[/tex] and the domain is [tex]x \ne 6[/tex]
The function is given as:
[tex]f(x) = \frac{1}{x - 4} - 6[/tex]
Express f(x) as y
[tex]y = \frac{1}{x - 4} - 6[/tex]
Swap the positions of x and y
[tex]x = \frac{1}{y - 4} - 6[/tex]
Add 6 to both sides
[tex]x + 6= \frac{1}{y - 4}[/tex]
Multiply both sides by y-4
[tex](x + 6)(y -4) =1[/tex]
Divide both sides by x + 6
[tex]y - 4 = \frac{1}{x + 6}[/tex]
Add 4 to both sides
[tex]y = \frac{1}{x + 6} + 4[/tex]
Rewrite as:
[tex]f^{-1}(x) = \frac{1}{x + 6} + 4[/tex]
Hence, the inverse function is [tex]f^{-1}(x) = \frac{1}{x + 6} + 4[/tex] and the domain is [tex]x \ne 6[/tex]
