The value of y varies directly
Which function represents the
relationship between x and y if y =
14 when x =
7/2
Answer:
Step-by-step explanation:
Answer is 7/3
The function that represents the relationship between x and y is (y = 4x) and this can be determined by using the given data.
Given :
The value of 'y' varies directly with 'x'.If y = 14 when x = 7/2.The following steps can be used in order to determine the function that represents the relationship between x and y:
Step 1 - According to the given data, the value of 'y' varies directly with 'x'. So, the mathematical expression for this situation is:
[tex]y \; \alpha \; x[/tex]
y = kx --- (1)
Step 2 - It is also given that the value of y = 14 when x = 7/2.
Step 3 - Now, substitute the value of 'y' and 'x' in the above expression.
[tex]\rm 14=\dfrac{7}{2}\times K\\[/tex]
K = 4
Step 4 - Now, substitute the value of K in the expression (1).
y = 4x

Government data assign a single cause for each death that occurs in the United States. The data show that the probability is 0.27 that a randomly chosen death was due to heart disease, and is 0.23 that it was due to cancer. What is the probability that a death was due to either heart disease or cancer
Answer:
0.50
Step-by-step explanation:
To answer this question, we have the following data available:
Probability of randomly chosen death caused by a heart disease = 0.27
Probability of randomly chosen death caused by cancer = 0.23
We are to calculate the probability that the death was as a result of either cancer or heart disease.
P(cancer or heart disease)
= 0.27 + 0.23
= 0.50

What you're looking for is to simplyfy the like terms and then isolate the variable. So basically, write everything down and solve it like normal. We know that straight lines are worth 180° and right angles are 90° so that's what's gonna be on one side of the equal sign, and all the other numbers on the other side. Like this:
8.
180 = x + 1 + 3x + 9
180 = 4x + 10
170 = 4x
42.5 = x
If it's hard to see what I'm doing, just write the first part out and solve like regular algebra then check if you got the same answer.

A vine maple grows fast when it is planted under the cover of cedar trees. One month after it is planted it has grown 9 inches, and after eight weeks it had grown 14 inches.
Write an equation that models the growth, in inches, of the vine maple as a function of time, in weeks
Answer:
[tex]y=\frac{5}{4} x+4[/tex]
Step-by-step explanation:
Using y = mx+c
m= [tex]\frac{y^{2}-y^{2}}{x^{2}-x^{1}}[/tex]
m=[tex]\frac{14-9}{8-4}[/tex]
m=[tex]\frac{5}{4}[/tex]
c=y-intercept
The question says that at 8 weeks the maple had grown 14 inches
By using y=mx+c we can find the y-intercept using one of the points as the x and y values and by using the slope
[tex]14=8\times\frac{5}{4} +c[/tex]
14=10+c
14-10=10+c-10
4=c
y-intercept = 4
Therefore the full equation is
[tex]y=\frac{5}{4} x+4[/tex]

What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
The value of C = m + 1
The value of B = m + 5
To calculate the value of 2 C + 3 B , substitute the value of B and C in the expression , we get
2 C + 3 B = 2 ( m + 1 ) + 3 ( m + 5 )
= 2 m + 2 + 3 m + 15
= 5 m + 17
Therefore , 2 C + 5 B = 5 m + 17
Hence , the expression 2 C + 3 B equals 5 m + 17 in standard form

If y varies directly as x and as the square of z, and y =
25
when x = 5 and z = 1, find y when x = 1 andz = 4
9
Answer: The answr is y=5/36 If my math is correct
Since the question is y=25/9 and x was 5 and z was 1, I thought 5 x 5 is 25, so x is 5. and 1 x 9 is 9 so z is 9. so then i multiplied 9x4 for z and 5 x 1 for x
A function is defined by the set of ordered pairs {(-2,3),(-1,4),(0,5)}. Which ordered pair below, if added to this set, would create a set that no longer represents a function.
1) (1,5)
2) (3,-2)
3) (-1,-4)
4) (-4,-1)
Answer: 3) (-1,-4)
Step-by-step explanation:
We define a function as a relationship that maps elements from one set (inputs) into elements of another set (outputs).
The functions have one important rule, each element in the domain (the set of possible inputs) can be mapped into only one element in the range (set of possible outputs).
Then if we have:
a ≠ b
and for an input x0.
f(x0) = a
and
f(x0) = b
this is not a function, as it maps the value x0 into two different values.
Then we know that the points {(-2,3),(-1,4),(0,5)} define our function.
Then the option that makes this relation to not be a function, will be any point that has the same input as some of the above ones, and different output.
the correct one is 3) (-1, -4)
Then the set will be:
{(-2,3),(-1,4),(0,5), (-1, -4)}.
Now we have two times the input -1, and different outputs, then this is not a function.
(-1, -4) would create a set that no longer represents a function.
Note that a relation is a function if each value of x is matched to only one value of x.
A relation does not qualify to be a function if one value of x is matched to more than one value of y.
For a function defined by the set of ordered pairs {(-2,3),(-1,4),(0,5)}:
The addition of an x-value that is already in the function will make the x-value to be matched to more than one y-value. This will disqualify the relation from being a function.
By considering the options given:
The option (-1, -4) would create a set that no longer represent a function because at x = -1, the values of y will be 4 and -4, which will make the graph fail the vertical line test

Pedro opened a deli in December. The table shows his profits and losses during his first four months of business. Month Profit/Loss ($) December + 724.37 January + 3,912.26 February - 1,051.51 March - 4,023.02 What is the overall profit or loss for the first four months the deli was open?
Answer:
437.90
Step-by-step explanation:
you add the negative numbers together, then the positive numbers. you take the answers from those and subtract them from each other.
The overall loss for the first four months the deli was open is $-437.90.
A firm has a profit when its income is greater than the cost. A loss is recorded when income is less than the total costs. A profit is represented with a positive sign (+) and a loss is represented with a negative sign (-).
In order to determine the overall profit or loss for the first four months add profits and subtract losses.
+ 724.37 + 3,912.26 - 1,051.51 - 4,023.02 = $-437.90.
Costs exceeds revenue so the Deli earns a loss of $437.90.
