How do you graph an inequality example?
Answers
The graph of an inequality is shown below -
What is an inequality equation?The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.
It's a line with a shaded side on one side to show which x-y pairings are the inequality's solutions.
Example -
Let us take a equation, 4x + 8y ≤ -24
Now, solve the above equation in the form of slope-intercept.
4x + 8y ≤ -24
or, 8y ≤ - 4x - 24
or, y ≤ -(1/2)x - 3
Now, the graph becomes according to the slope-intercept form is:
Here we noticed that,
This side of the inequality is shaded below (instead of above) because y is lower than (or equal to) the other side.
Because working with a "or equal to" inequality, draw a solid line rather than a dashed one. Points on the solid line denote locations where the inequality has been solved.

Jonathan is preparing for a triathlon he biked 3.5 miles on Thursday and 4.25 miles on Friday on Saturday he biked 12 miles how much farther did he bike on Saturday than he did on Thursday and Friday combined
Answers
Answer: 4.25 miles
Step-by-step explanation:
The distance he biked on Thursday and Friday combined is:
= 3.5 + 4.25
= 7.75 miles
On Saturday he biked 12 miles. The number of miles he biked over Thursday and Friday is:
= 12 - 7.75
= 4.25 miles

A number x is rounded to 1 decimal place and its 3.7
write down the error interval for x
Answers
The error interval for x would be (3.65, 3.75), indicating that the true value of x lies within this range.
Given that a number x is rounded to 1 decimal place and its 3.7.
We need to find the error of the interval for x,
To determine the error interval for the rounded number 3.7, we need to consider the possible range of values that could have been rounded to 3.7 when rounded to 1 decimal place.
When rounding to 1 decimal place, we look at the digit immediately to the right of the decimal point. If this digit is 5 or greater, we round up. If it is less than 5, we round down.
In this case, 3.7 is the rounded value, which means the original number could have been rounded up from a value greater than or equal to 3.65 or rounded down from a value less than 3.75.
Therefore, the error interval for x would be (3.65, 3.75).

Answers
Answer:
D. 16
Step-by-step explanation:
You first need to find the total percentage who liked vanilla, then subtract it from the total percentage of chocolate.
To find the total of those who liked vanilla you would have to add the given percentages and then subtract that from 100.
Chocolate: 42%
Strawberry: 18%
Coffee: 14%
Vanilla: x
42 + 18 = 60 + 14 = 74%
100 - 74 = x
Vanilla = x = 26%
To find how many more like chocolate than vanilla, you would subtract the two percentages.
Chocolate: 42%
Vanilla: 26%
42 - 26 = 16

What’s the equation
Answers
Answer:
The equation of the line is;
y = 0.8x + 1
Step-by-step explanation:
Here, we want to get the equation of the line
The general equation of a straight line is;
y = mx + b
m
is the slope and b is the y-intercept
The y-intercept is simply the point on the y-axis where the line crosses the y-axis
we have this point at (0,1)
so we have;
y = mx + 1
to get m, we get any other point on the line and substitute its coordinates before we solve for m
we can identify the point (-2.5, -1)
substituting the coordinates
-1 = -2.5(m) + 1
-2.5m = -1-1
-2.5m = -2
m= 2/2.5
m= 0.8
so we have the equation of the line as;
y = 0.8x + 1

Step-by-step explanation:
In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
The formula to solve the above question is
1/2absinθ
a = 100 inches
b = 740 inches
θ = 159°
The area of the triangle =
1/2 × 100 × 740 × sin 159°
= 13259.61 square inches
Approximately = 13260 square inches
Therefore, the area of DEF = 13260 square inches

If Cole flips a coin three times, what is the probability that he will flip three tails in a row? 4. Based on collected data from the past 5 basketball practices, Linda has a 32% for making her free throws. If she shoots 175 more times, how many will she expect to make based on her percentage? !!! DUE IN 18 MINS !!!
Answers
Answer:
1. The probability that she throws a multiple of 3 and flips tails is 1/6
2. The probability that Cymra draws a red marble put it back and draws a red marble again is 25/196
3. The probability that Cole flips three tails in a row, P(3T) is 1/8
4. The number of shots Linda is expected to make if she takes 175 shots is 56
Step-by-step explanation:
1. The number of sides on the special die Li rolls = 12 sides
The numbers on the die are 1 through 12
The number of faces on the penny = 2 (heads and tails)
The number of multiples of 3 on the die = 3, 6, 9, and 12 = 4
The probability that she throws a multiple of 3, P(3) = 4/12 = 1/3
The probability that she flips tails rather than heads = 1/2
∴ The probability that she throws a multiple of 3 and flips tails = 1/3 × 1/2 = 1/6
2. The number red marbles in the bag = 5
The number green marbles in the bag = 6
The number blue marbles in the bag = 3
The total number of marbles in the bag = 5 + 6 + 3 = 14
The probability that Cymra draws a red marble put it back and draws a red marble again is given as follows;
The probability with replacement of picking two red marbles = 5/14 × 5/14 = 25/196
3. The probability that Cole flips three tails in a row P(3T) = (1/2)×(1/2)×(1/2) = 1/8
The probability that Cole flips three tails in a row, P(3T) = 1/8
4. The percentage of times Linda makes her free throws in the past 5 basketball practices = 32%
The number of shots she is expected to make if she takes 175 shots = 175 × 32/100 = 56.

What is the equation of the parabola with focus(1, 1/2)

B. Y=-3/16x^2
C. Y=1/5x^2+2/5x+31/20
D. Y=-3/5x^2-14/31x+71/16
Answers
Given:
Focus of a parabola = [tex]\left(1,\dfrac{1}{2}\right)[/tex]
Directrix: [tex]y=3[/tex]
To find:
The equation of the parabola.
Solution:
The equation of a vertical parabola is:
[tex]y-k=\dfrac{1}{4a}(x-h)^2[/tex] ...(A)
Where, [tex](h,k)[/tex] is center, [tex](h,k+a)[/tex] is focus and [tex]y=k-a[/tex] is the directrix.
On comparing the focus, we get
[tex](h,k+a)=\left(1,\dfrac{1}{2}\right)[/tex]
[tex]h=1[/tex]
[tex]k+a=\dfrac{1}{2}[/tex] ...(i)
On comparing the directrix, we get
[tex]k-a=3[/tex] ...(ii)
Adding (i) and (ii), we get
[tex]2k=\dfrac{7}{2}[/tex]
[tex]k=\dfrac{7}{4}[/tex]
Putting [tex]k=\dfrac{7}{4}[/tex] is (i), we get
[tex]\dfrac{7}{4}+a=\dfrac{1}{2}[/tex]
[tex]a=\dfrac{1}{2}-\dfrac{7}{4}[/tex]
[tex]a=\dfrac{-5}{4}[/tex]
Putting [tex]a=\dfrac{-5}{4},h=1,k=\dfrac{7}{4}[/tex] in (A), we get
[tex]y-\dfrac{7}{4}=\dfrac{1}{4\times \dfrac{-5}{4}}(x-1)^2[/tex]
[tex]y-\dfrac{7}{4}=\dfrac{-1}{5}(x^2-2x+1)[/tex]
[tex]y-\dfrac{7}{4}=-\dfrac{1}{5}(x^2)-\dfrac{1}{5}(-2x)-\dfrac{1}{5}(1)[/tex]
[tex]y=-\dfrac{1}{5}x^2+\dfrac{2}{5}x-\dfrac{1}{5}+\dfrac{7}{4}[/tex]
On further simplification, we get
[tex]y=-\dfrac{1}{5}x^2+\dfrac{2}{5}x+\dfrac{35-4}{20}[/tex]
[tex]y=-\dfrac{1}{5}x^2+\dfrac{2}{5}x+\dfrac{31}{20}[/tex]
Therefore, the equation of the parabola is [tex]y=-\dfrac{1}{5}x^2+\dfrac{2}{5}x+\dfrac{31}{20}[/tex].
Note: Option C is correct but the leading coefficient should be negative.

If you were to flip a coin 500 times, how many times would you
theoretically expect the coin to land on heads?
Answers
Answer and Step-by-step explanation:
Theoretically, we should expect the coin to flip 250, or very close to 250 times, and land on heads.
This is because the probability of getting heads is [tex]\frac{1}{2}[/tex], or 50%.
There is a 50% chance of landing heads or tails, so that means it would land 250 times on heads out of 500 flips of the coin.
