Answer:
n< 7/2 or n< 3.5
Step-by-step explanation:
3n -11 > 5n -18
subtract 3n on both sides:
-11 > 2n-18
Add 18 on both sides:
7 > 2n
7/2 > n
n< 7/2

Consider the equation below. log Subscript 4 Baseline (x + 3) = log Subscript 2 Baseline (2 + x) Which system of equations can represent the equation?
Answer:the second one
Step-by-step explanation:
y1= log 3 etc so it the second one
The correct system of equations which can represent the equation are,
⇒ y₁ = log (x + 3) / log 4
⇒ y₂ = log (2 + x) / log 2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ log₄ (x + 3) = log₂ (2 + x)
Now, We know that;
The formula is,
logₐᵇ = log b / log a
Hence, By using above rule we get;
The correct system of equations which can represent the equation are,
⇒ log₄ (x + 3) = log (x + 3) / log 4
⇒ log₂ (2 + x) = log (2 + x) / log 2
Thus, The correct system of equations which can represent the equation are,
⇒ y₁ = log (x + 3) / log 4
⇒ y₂ = log (2 + x) / log 2

Choose 3 values for x that would make this inequality true. 24>2 (x+2)
Answer:
9, 2, 0
Step-by-step explanation:
Solving the inequality
24 > 2(x + 2) ← divide both sides by 2
12 > x + 2 ( subtract 2 from both sides )
10 > x
Thus we require values of x that are less than ( but not equal to ) 10
These are 9, 2 and 0
what is the rate of change of y with respect to x for this function?
Answer:
Given the function: y=f(x) = 3x+2
when x=-2 at the beginning of the interval [-2, 5],
then;
y = 3x+2 begins at
y= 3(-2)+2 = -6+2= -4.
and
when x=5 at the end of the interval [-2, 5],
y = 3x+2 ends up at
y= 3(5)+2 = 15+2= 17.
So,
y has changed -4 to 17, which is a change of 17-(-4)= 17+4 = 21
and x has changed from -2 to 5, which is a change of 5-(-2)=5+2=7
So, the average rate of change of y with respect to x over the interval
[-2, 5] is given by ;
=
Therefore, the average rate of change y with respect to x over the interval is, 3

Find each unit rate, A car travels 210 mi in 14 h.
Hint: How many miles per hour?
Answer:
15 miles per hour
Step-by-step explanation:
Since we're looking for miles per hour ([tex]\frac{miles}{hour}[/tex]) we can just replace the variables in the fraction. So, 210 divided by 14.
[tex]\frac{210}{14} \\=15 miles per hour[/tex]

2. The local Farm Market sells peppers at five for $2.25. Complete the rate table Number of Peppers 1 2 4 5 10 15 20 100 Cost 2.25 What is the constant of proportionality? How do you know?
Answer:
K = $0.45
1____ 2__ 4 __5___10__ 15__ 20__ 100
0.45_0.9_1.8_2.25_4.5_6.75__9___45
Step-by-step explanation:
Given the data:
Number of pepper: 1 2 4 5 10 15 20 100
Cost :
Cost of 5 pepper = 2.25
Using variation :
Cost = number of pepper * k
K = CONSTANT of proportionality
k = cost / number of pepper
k = 2.25 / 5
k = 0.45
Hence,
Cost of pepper = k * number of pepper
Number of pepper:
Cost :
1____ 2__ 4 __5___10__ 15__ 20__ 100
0.45_0.9_1.8_2.25_4.5_6.75__9___45
Does anyone know how to do this?
Answer:
yes
Step-by-step explanation:
the angle that is equal to 57 and angle y are supplementary angles meaning that the two values added together will equal 180. So all you have to do is subtract 57 from 180 to get 123. So y = 123

A 7th grade math class is having a year end party. So far, 16 students have paid a total of $132.
Write an equation for the cost c for s students.
Explain how the equation was created. If all 25 students turn in money, how much will be collected?
The class teacher contributes $25. How does this contribution affect the equation made in Part A?
Pls hurry
Answer:
A) 8.25c + 25s = 206.25
B)This contribution affects the equation because it adds money and a person and because she is adding more than the normal amount that each student pays
Step-by-step explanation:
132/16= 8.25
each student paid $8.25
Suppose that $8000 is placed in an account that pays 11% interest compounded each year what's the amount after 1 year ? What's the amount in the account after 2 years
Answer:
A = $9,760.00
Step-by-step explanation:
I = A - P = $1,937.50
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year.
Solving our equation:
A = 10000(1 + (0.03875 × 5)) = 11937.5
A = $11,937.50
The total amount accrued, principal plus interest, from simple interest on a principal of $10,000.00 at a rate of 3.875% per year for 5 years is $11,937.50.

Kiran says that -2<-5 do you agree with Kiran
Answer:
No it is not possible
Step-by-step explanation:
If two triangles are congruent then they are similar.
Answer:
False.
Step-by-step explanation:
Note the signs:
< is less than
> is greater than
= is equal too
≤ is less than or equal too
≥ is greater than or equal too
~
In this case, Kiran says that -2 is less than -5. However, if you look at a number line (in which the further left it is, the smaller the digit in value, while to the right, the greater the value), -5 is found to the left of -2. Therefore, -2 > -5.
Attached is a number line.

Which inequality represents the following number line?
+
-10-9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
Select one:
a. x < -6
b.X > -6
C.XS-6
d. x > -6
Answer:
b. x > -6
Step-by-step explanation:
> [greater than], and < [less than] inequalities are not filled in because the value is not included, but is only greater or less than.
≥ [greater than or equal to], and ≤ [less than or equal to] inequalities are filled in because the value is included, and it is greater than or less than.
Given that there is an empty circle with an arrow moving in the positive direction from -6, the inequality must be a greater than, and since the value is -6, x > -6.
