Answer:
x ≥ 16 or x < 0
Step-by-step explanation:
You want ...
(x -4)/x ≥ 3/4
4(x -4) ≥ 3x . . . . . . multiply by 4x (requires x > 0)
4x -16 ≥ 3x
x ≥ 16 . . . . . . . . . . add 16-3x
__
For x < 0, multiplying by 4x gives ...
4(x -4) ≤ 3x
4x -16 ≤ 3x
x ≤ 16 . . . . . and x < 0
__
There are two sets of solutions:
x < 0 or x ≥ 16

The sum of two positive numbers is 4 and the sum of their cubes is 28. What is the product of the two numbers?
Answer:
3
Step-by-step explanation:
system of equations:
[tex]a+b=4[/tex]
[tex]a^3+b^3=28[/tex]
[tex]a=4-b[/tex]
plug in for a in other equation and solve
[tex](4-b)^3+b^3=28[/tex]

[tex]0=3-4b+b^2[/tex]
[tex]0=(b-3)(b-1)[/tex]
[tex]b = 3[/tex]
or
[tex]b=1[/tex]
plug into other equation to get a
[tex]a=4-b=4-3=1[/tex]
or
[tex]a=4-b=4-1=3[/tex]

Elizabeth drove 2 fifths of a mile in 30 seconds. What is Elizabeth’s speed
Answer:
0.8 miles in a minute, which would be 40 miles a hour.
Step-by-step explanation:
2/5 = 0.4
0.4 times 2 = 0.8
30 seconds times 2 = 60 seconds or 1 minute
60 times 0.8 = 40
60 times 1 minute = 60 minutes or 1 hour
40 miles in an hour or known as 40 miles a hour.

Transfer into algebraic symbols: 11 less than the square of a number. Use x to represent the number.
Answer:
[tex]11-x^2[/tex]
Step-by-step explanation:
"11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².
What is inequality?An inequality compares two numbers or expressions. For example, we can write -
2x + 3 > 5
2x + 9 < 1
Given is the mathematical statement as -
" the square of a number is greater than 11"
We can write the mathematical statement as an algebraic inequality as follows. Let the number be {x}. We can write -
11 < x²
Therefore, "11 less than the square of a number" can be written as an algebraic inequality as → 11 < x².

Bob needs to read 3 novels each month. Let N be the number of novels Bob needs to read in M months, Write an equation relating N to M. Then use this equation to find the number of novels Bob needs to read in 17 months.
Answer:
Equation: n=3m; Bob needs to read 51 novels over 17 months.
Step-by-step explanation:
Since the number of novels Bob needs to read (n) depends on the amount of months (m) we can say that n is the dependent variable and m is the independent. Since x is always independent and y is always independent we can say that m is going to stand for x and n is going to stand for y. Each month Bob reads 3 novels so we can write the equations as n=3m. To find out how many books he needs to read in 17 months plug it into the equation. n=3(17) -------------------> n=51

What is the value of p if the expression 4(n+7) is equivalent to (n+p)4?
Answer:
p = 7
Step-by-step explanation:
set the expressions = to each other
4(n+7) = 4(n+p)
distribute the 4 on both sides(multiplying the numbers on the inside)
4n+28 = 4n+4p
subtract the 4n from the right and left
28 = 4p
divide by 4
p = 7
