Which of the following lines is parallel to the given line?
Answer:
y=10x
Step-by-step explanation:
Find the slope of the original line and use the point-slope formula
y−y1=m(x−x1) to find the line parallel to y=10x−45
.
Vertical lines have an undefined slope.
True or False
Answer:
True
Step-by-step explanation:
The 'base' of the line has length zero.
Answer:
True.
Step-by-step explanation:
You take 2 points and find gradient of a line and if you get a constant. For example, m=5. Then 5 over 0 (the denominator is what matters, it must be 0) and that's how you know it's a vertical line and has undefined slope.
Which of the following gives a single solution of the inequality |x+3|-2<0 and shows a graph that can be used to determine the entire solution set of the inequality?
The solution to the inequality |x + 3| - 2 < 0 is -5 < x < -1 as shown in the graph attached
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Inequality is an expression used to show the non equal comparison of two or more numbers and variables.
Given that:
|x + 3| - 2 < 0
Hence:
(x + 3) - 2 < 0 and -(x + 3) - 2 < 0
x < -1 and x > -5
The solution to the inequality |x + 3| - 2 < 0 is -5 < x < -1 as shown in the graph attached

Answer:
about 8.2 cm
Step-by-step explanation:
The key is to realize that the volume never changes.
The formula for the volume of a sphere is (4/3)*pi*radius^3
22/7 is being substituted in place of pi in this problem
The volume of one of the small spheres is
(4/3)*(22/7)*2^3 is about 33.524 cm^3
64 of those spheres would have a volume of 33.524*64, or about 2145 cm^3
Now, the problem is to find a sphere with a volume of 2145 cm^3
Volume = (4/3)*(22/7)*radius^3
plug in and solve
2145 = 4.1905*r^3
r^3=511.87
r is about equal to 8.2 centimeters
What number is it that, when multiplied by 18,27,36,45,54,63,72,81, or 99, gives a product in which the first and last figures are the same as those in the multiplier, but which when multiplied by 90 gives a product in which the last two figures are the same as those in the multiplier?
The given multipliers are factors of 9, the possible number will have 1 as first and last digit which gives the number as 101
How can the correct number be found?The given numbers are;
18, 27, 36, 45, 54, 63, 72, 81, 99
Given that the first and the last figures are those of the multipliers, we have;
The first and last and last digit of the number can be 1, which gives;
Possible numbers includes; 11 and 101
By trying the possible numbers, the difference found is presented as follows;
99 × 11 = 1089 (The first and the last digit are not the same as the multiplier)
99 × 101 = 9999 (First and last digit are not the same as the multiplier)90 × 11 = 990
90 × 101 = 9090
The correct option is therefore 101

A. Started in Quadrant III and ended in Quadrant I.
B. Started in Quadrant I and ended in Quadrant II.
C. Started in Quadrant II and ended in Quadrant IV.
D. Started in Quadrant I and ended in Quadrant III.
Started in Quadrant II and ended in Quadrant IV.
==========================================================
Explanation:
Refer to the diagram below. It shows how the four quadrants are labeled using roman numerals. We start in the upper right corner (aka northeast corner) and work counterclockwise when labeling quadrant I, II, III, and IV in that order.
The green point A is located in quadrant II in the northwest. Meanwhile point B in red is in the southeast quadrant IV.
Therefore, we started in quadrant II and ended in quadrant IV which points us to choice C.
At a school book fair, 3/5 of the books are nonfiction books. of the nonfiction books, 1/4 are animal books. what fraction of the book fair books are animal books? move numbers to the boxes to show the fraction.
Answer:
Animal books make up (3/20) of all books
Step-by-step explanation:
Let X be the total number of books, made up of nonfiction, animal, and all others.
(3/5)X are nonfiction books.
Of the nonfiction books, 1/4 are animal books: (3/5)*(1/4)X = (3/20)X are animal books
[This means that Nonfiction, less animal books is: (3/5)X - (3/20)X]
Animal books make up (3/20) of all books.

Solve The Following
( Solving equations)
Answer:
a) x = 4
b) x = 1
Step-by-step explanation:
a) [tex]\frac{4x-1}{2} = x + 7[/tex] multiply both sides by 2 so we can simplify the fraction by getting rid of 2
4x - 1 = 2x + 7 transfer like terms to the same side of the equation
4x - 2x = 7 + 1
2x = 8 divide both sides by 2
x = 4
b) [tex]3x + 2 = \frac{2x+13}{3}[/tex] again, get rid of the fraction by multiplying both sides by 3
9x + 6 = 2x + 13 transfer like terms to the same side of the equation
9x - 2x = 13 - 6
7x = 7 divide both sides by 7
x = 1

First statement:
p + q is not a prime number.
Let p = 7
q = 9
= 7 + 9 = 16 (16 is not a prime)
= 7×9 = 63 (no factor of 63)
p = 7, q = 7

The purpose of statistical inference is to make estimates or draw conclusions about a _____. a. population based upon information obtained from the sample b. mean of the sample based upon the mean of the population c. sample based upon information obtained from the population d. statistic based upon information obtained from the population
a)The purpose of statistical inference is to make estimates or draw conclusions about a population based upon information obtained from the sample.
Statistical inference is the process of drawing conclusions about populations or scientific truths from data. There are many ways to make inferences, including statistical modeling, data-driven strategies, and the explicit use of designs and randomization in analyses.
Hypothesis testing is a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or population probability distribution.
First, a preliminary assumption is made about the parameter or distribution. This assumption is called the null hypothesis and is denoted H0.
An alternative hypothesis (denoted Ha) is then defined, which is the opposite of what is stated in the null hypothesis. The hypothesis testing procedure involves using sample data to determine whether or not H0 can be rejected. If H0 is rejected, the statistical conclusion is that the alternative hypothesis Ha is true.

When two musical notes are a "fifth" apart, the frequency of the lower note is 2/3 the frequency of the higher note. Using f as the frequency of the higher note, write an expression for the frequency
of the lower notes
Frequency is a physical quantity that relates to the number of cycles made by a wave per second. Therefore the required expression for the frequency of the lower note is: [tex]\frac{2}{3}[/tex] f
A wave is a phenomenon that propagates through a material medium without any permanent effect on the molecules of the medium. It transmits energy from one end of the medium to another. Examples are sound waves, light waves, electromagnetic waves, etc.
The propagation of a wave gives rise to frequency. Which can be defined as the number of cycles made by a wave per second. And it is measured in Hertz.
Let the frequency of the higher note be represented by f, and that of the lower note by [tex]f_{l}[/tex]. Thus, we have;
[tex]f_{l}[/tex] = [tex]\frac{2}{3}[/tex] f

every subscription that she sells. Sophie gets $3 per subscription sold, in addition to a base
wage of $4 per hour. If they each sell a certain number of subscriptions in an hour, they will
end up earning the same amount. How much would each one earn?
Write a system of equations, graph them, and type the solution.
Answer:
The each have to place 2 subscriptions
Step-by-step explanation:
Adriana
E (earnings) = 6 + 2*x where x is the number of subscriptions
Sophie
E (earnings) = 4 + 3x
For them to earn the same amount, their right sides must be equated.
4 + 3x = 6 + 2x Subtract 2x from both sides
4 + 3x - 2x = 6+ 2x - 2x Combine
4 + x = 6 Subtract 4 from both sides
4 - 4 + x = 6 - 4
