Write the algebraic expression 9r+2 as a verbal expression
Answer:
We conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.9 times a number, r, increase by 2.Step-by-step explanation:
Given the algebraic expression
9r+2
We know that 9r is the product of 9 and 3.
Thus,
9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.
or it can be also verbally expressed such as:
9 times a number, r, increase by 2.
Therefore, we conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.9 times a number, r, increase by 2.Directions: Find the value of x. Round your answer to the nearest tenth.

Simplify the expression (3.5x - 2.7y) + (-12.8x + 15.8y)
Answer:
-9.3x + 13.1y
Step-by-step explanation:
(3.5x - 2.7y) + (-12.8x + 15.8y) = 3.5x - 2.7y - 12.8x + 15.8y =
= 3.5x - 12.8x - 2.7y + 15.8y = (3.5 - 12.8)x - (2.7 - 15.8)y =
= -(12.8 - 3.5)x + (15.8 - 2.7)y = -9.3x + 13.1y
because
-(-a) = a
-(a + b) = -a - b
-(a - b) = -a + b = b - a
a + (-b) = a - b

Write and graph an equation in two variables that shows the relationship between the time and the distance.
Moves 15 meters in 1 second.
Answer:
The relation between the time and the distance will be:
y = 15x
The graph of the equation y = 15x is attached below.
Step-by-step explanation:
We know that the equation of linear function in two variables in the slope-intercept form is
y = mx+b
where
m is the rate of change or slope b is the y-interceptLet y be the distance
Let t be the time
Given that the object moves 15 meters in 1 second.
Thus, the rate of change or slope = m = 15
As there is no initial condition in our case.
Thus the y-intercept b = 0
Now, substituting m = 15 and b = 0 in the linear function
y = mx+b
y = 15x + 0
y = 15x
Therefore, the relation between the time and the distance will be:
y = 15x
The graph of the equation y = 15x is attached below.
Examples:
Calculate the distance in 1 second
put x = 1 in the equation
y = 15(1) = 15 meters
Calculate the distance in 10 second
put x = 10 in the equation
y = 15(10) = 150 meters
Solve each equation.

Which of the following x-values are approximate solutions to the equation f (x) = g(x) ? Select ALL that apply.
A) x = -3.3
B) x = -2
C) x = 2
D) x = 5.2
E) x = 6.5
Answer:
A and D
Step-by-step explanation:
I could be wrong but the solutions are the points of intersection between the two functions. By looking at it. I can see that its about -3.3 and 5.2
Hope this helps!
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.,Functions which repeats their values after a fixed interval, are called periodic function.
WE have been given the function x as
f (x) = g(x)
Therefore,
3(17x-6.5) = 108
Then Divide each side by 3;
3/3(17x-6.5) = -108/3
17x - 6.5 = -36
Add 6.5 to each side;
17x-6.5+6.5 = -36+6.5
17x = 42.5
Divide by 17;
17x/17 = -42.5/17
x = -3.3
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.

out of these numbers which of them differ by 46. 29,17,38,71,35,63,24
Answer:
71
Step-by-step explanation:
Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd
71
We do not need to look at all differences.
We need to find two numbers fairly far appart,
and not all look promising.
You could look at approximate differences,
or you could look at the last digit.
71-35 and 63-17 are the only promising differences,
because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,
and when you calculate the last digit you calculate
11-5=6 and 13-7=6.
71-35=36

Which of the following is a solution to this inequality?
y > 1/2x + 2
Answer:
We conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.
Step-by-step explanation:
Given the inequality
y > 1/2x + 2
FOR (1, 4)
y > 1/2x + 2
substituting x = 1, and y = 4
4 > 1/2(1) + 2
4 > 1/2+2
4 > 5/2
TRUE!
Reason: It is true because 4 is indeed greater than 5/2
Thus, (1, 4) satisfies the inequality.
Therefore, (1, 4) is a solution to this inequality.
FOR (-1, 1)
y > 1/2x + 2
substituting x = -1, and y = 1
1 > 1/2(-1) + 2
1 > -1/2+2
1 > 3/2
FALSE!
Reason: It is false because 1 can not be greater than 3/2
Thus, (-1, 1) DOES NOT satisfy the inequality.
FOR (2, 3)
y > 1/2x + 2
substituting x = 2, and y = 3
3 > 1/2(2) +2
3 > 1+2
3 > 3
FALSE!
Reason: It is false because 3 can not be greater than 3.
Thus, (2, 3) DOES NOT satisfy the inequality.
FOR (0, 2)
y > 1/2x + 2
substituting x = 0, and y = 2
2 > 1/2(0) +2
2 > 0+2
2 > 2
FALSE!
Reason: It is false because 2 can not be greater than 2.
Thus, (0, 2) DOES NOT satisfy the inequality.
Therefore, we conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.

All you have to do is write the function!
A software CD can be manufactured for $0.10 each. The development cost to produce the CD is $500,000. The first 200 CDs were used by testers to test the functionality of the software and were not sold.
Write a function, f, for the average cost, in dollars, of a saleable software CD where x is the number of saleable software CDs.
Answer:
The function that represents the average cost in dollars of saleable software CD is given as follows;
f(x) = 500,020/x + 0.10
Step-by-step explanation:
The given parameters are;
The cost of manufacture of each software CD = $0.10
The development cost to produce the CD = $500,000
The number of CDs that are not sold = The first 200 CDs
The total cost of production. 'C', of the the CD is given as follows;
C = $500,000 + $0.10×200 = $500,020
The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;
f(x) = (C + 0.10·x)/x = C/x + 0.10
∴ f(x) = 500,020/x + 0.10.
