Answer: OPTION A
Step-by-step explanation:
You can convert 30 kilograms to grams (), then:
Then, if a book in the bookcase has a mass of 400 grams and you need to find the number of books of the same mass that would take to equal the mass of the bookcase, you can divide the weight of the bookcase (in grams) by the weigth of one of these books.
Therefore:
Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3
Step-by-step explanation: Hello! Well first the question says to find the GCF and you find that by finding prime factors in each number. Then you would want to subtract 96-72 and get the answer of 24 so you would be able to make 24 gift bags. Hope this helps!!
Given line : y = 5
=> y = 0×x + 5
Comparing it with y = mx + c
slope of line, m = 0
Thus, this line is parallel to x axis.
A line perpendicular to it will be parallel to y axis.
So the perpendicular line will be of the form: x = k
where k is a constant.
It passes through (-7,-5)
Thus
x = k
=> -7 = k
=> k = -7
Thus, equation of perpendicular line is x = -7
Any number power zero = 1
