Which inequality represents the graph shown below?
Answer:
x>-2
since the arrow goes to the right from -2 it is definitely greater than -2. now see that the line does not include the value -2 itself.. thus, we say it is greater than -2
Answer:
x > -2
Step-by-step explanation:
Details understood from the graph :
Open dot from starting pointIncreases from -2Hence,
Open dot means > or <Greater means ⇒ >The inequality is : x > -2Enter the number that belongs in the green box.
Answer:
B. 2
Step-by-step explanation:
Here we need to the find the value in the green box.
Hence, only evaluate the part to the left of the operation sign.

Step-by-step explanation:
to solve this equation you can distribute the two throughout the equations
an easy way to see which one is correct is to check the symbols and what they multiply to
the first expression is obviously wrong as it has a negative symbol
we can now look at the second to last ones
the third one is wrong because 4x and 2 multiply to 6x
the last one is wrong because 2 and 8 do not multiply to 8
the answer is the third one

what is the y-intercept of this line y= x/5-12
Answer:
(0, -12)
Step-by-step explanation:
The y-intercept of a line can be found when taking x = 0.
Therefore,
y = 0 - 12y = -12The y-intercept of the line is (0, -12)

a. Histogram
b. Pie graph
c. Bar graph
d. Picto graph
A graph that uses bars of various heights to represent the frequencies is a Histogram
A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.
Therefore, a graph that uses bars of various heights to represent the frequencies is a Histogram

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Each horse ride lasts 5 minutes, with a 1-minute pause in between the next ride. After every hour and a half, the horse is given a rest.
Let's assume the number of children that rides the horse is x
Then we can frame a linear equation in one variable:
5x + 1x = 60+30 (After every hour and a half, the horse is given a rest.)
After solving we get:
6x = 90
x = 15 rides
Thus, the 15 children get an opportunity to ride a horse before they rest if the horse ride lasts 5 minutes with a 1-minute pause in between the next ride. After every hour and a half, the horse is given a rest

f(x) > 0 for (-2.203, -1) U (2.203, ∞)f(x) < 0 for (-∞, -2.203) U (-1, 2.203)Step-by-step explanation:
A graph shows real zeros at ±2.203 and -1. The value of f(x) changes sign at each of these.
The positive leading coefficient indicates the graph trends generally upward, so the function will be positive in intervals with an even number of zeros to the right.
f(x) positiveThere are an even number of zeros to the right of x = 2.203 and the interval (-2.203, -1).
f(x) is positive in the intervals (-2.203, -1) or (2.203, ∞).
f(x) negativeThe function will be negative where it is not positive (except at the zeros)
f(x) is negative in the intervals (-∞, -2.203) or (-1, 2.203).
_____
Additional comment
The graph shows the only rational real root of the function is x=-1. Using synthetic division to reduce the polynomial, we find ...
f(x) = (x +1)(x^4 -3x^2 -9)
The remaining factor is a quadratic in x^2, which has roots ...
x = ±√(1.5 ±√11.25)
The real roots are approximately ±2.20320266118. The value 2.203 used above is a stand-in for the exact value √(1.5 +√11.25)).

Suppose that a gated community consisting of 40 houses requires:
500 liters of water everyday for common utilities of the community, and
a certain amount of water everyday per house.
Assuming that the water tanker supplies no more than 4500 liters of water per day to this community, what is the maximum amount of water that can be used by each house on a daily basis?
liters
The maximum amount of water that can be used by each house on a daily basis is 100 liters.
How to calculate the amount of water?From the information given, the gated community consists of 40 houses and requires 500 liters of water everyday for common utilities of the community.
The maximum amount of water that can be used by each house on a daily basis will be:
4500 = 40x + 500
40x = 4500 - 500
40x = 4000
x = 4000/40
x = 100

At lunch, Kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium. Her doctor told her to reduce her sodium to no more than 4,000 milligrams per week. Which inequality represents x, the number of microwave burritos, and y, the number of peanut butter sandwiches, she can eat each week?
490x + 700y < 4000
490x + 700y ≤ 4000
490x + 700y > 4000
490x + 700y ≥ 4000
Answer: 490*x + 700y ≤ 4000
It is ≤ as it can either be equal to 4000 per week or less than.

Total cost, 3 orders of fries and 4 drinks:
Total cost, ff orders of fries and dd drinks:
Answer:
$7.43
Step-by-step explanation:
f (fries) = 1.01
d (drinks) = 1.07
1.05f + 1.07d = ?
To solve this problem, you need to replace the variable with the amount of each item.
1.05(3) + 1.07(4) = ?
Now we can solve by multiplying and adding:
3.15 + 4.28 = ?

Mrs. Smith gave two classes the same quiz. She randomly selected 5 students from each class to compare the classes. The scores of the five students are shown below. Class A: 80, 82, 74, 92, 94 Class B: 82, 80, 88, 86, 82
What are the mean and range for each class ?
Class A- mean = 84.4 range = 14
Class B - mean = 83.6. range = 8
Using the information found in the question above which class mrs smith report had the more consistent performance on the unit test ?, explain what this means in terms of the situation
The mean and range for class A are 84.4 and 20 while the mean and range for class B are 83.6 and 8. Class B is more consistant then class A.
How to calculate the mean?We can see from the data that the consistency of class B is more becuase the repeatation of the same score is more in class B then class A and the range of class B is also less then the class A.
It should be noted that mean simply means average. It's the addition of the numbers divided by the total numbers.
In this case, the computation will be:
Class A: Mean = 422/5= 84.4.
Range: 94-74 = 20
Class B: Mean = 418/5 = 83.6.
Range= 88-80 = 8
