how many solutions are in the equation -(4x+7)= - 2+4x
Answers
-(4x + 7) = -2 + 4x
We're trying to solve for "x," so let's first simplify this equation.
**Remember : a negative times a positive is a negative!**
-4x - 28 = -2 + 4x
Now, we need to get "x" onto its own side of the equal sign.
So, let's add 28 to both sides.
-4x - 28 (+28) = -2 + 4x (+28)
Simplify.
-4x = 4x + (28 - 2)
Then, subtract 4x from both sides.
-4x - 4x = (28 - 2)
Simplify!
-8x = 26
Divide both sides by -8.
-8x ÷ -8 = 28 ÷ -8
Simplify.
x = -28/8
Simplify.
x = -14/4
Simplify again.
x = -7/2
So, because x has a solution, this particular equation only has 1 solution!

Without graphing estimate the x-intercepts of the graph of f(x)=7x^2+9x+1 to the nearest tenth.
Answers
at x-intercept f(x)=0, thus when f(x)=0
f(x)=7x^2+9x+1
we shall have:
0=7x^2+9x+1
solving the above using quadratic formula the above we get:
x=[-b+/-sqrt(b^2-4ac)]/2a
from the function, a=7, b=9 and c=1
thus plugging the values in the formula we obtain:
x=[-9+/-sqrt(9^2-4(7*1))]/(2*7)
x=[-9+/-sqrt(53)]/14
x=-9/14+√54/14
or
x=-9/14-√54/14

Matrix is handing out treats at a local protest to promote his new detective agency. He allows each participant to reach into his bag of goodies and select a treat. Then he replaces it with the same treat and shakes the bag before offering a treat to another person. Matrix’s bag bag of goodies contains the treats below.
Which model shows the probability of selecting each type of treat from his bag?
Answers
Answer:
D. Swordfish treat: 20%
Lizard Lollies : 50%
Puffer pops: 30%.
Step-by-step explanation:
We are told that Matrix is handing out treats at a local protest to promote his new detective agency.
Since he replaces the chosen treat each time with the same treat, so number of each treat remains same and it will not affect the probability for next person to choose the treat.
We know that [tex]\text{Probability}=\frac{\text{The number of favorable outcomes}}{\text{Total number of possible out comes}}[/tex].
Let us find probability of choosing each type of treat one by one.
[tex]\text{Probability of choosing swordfish treat}=\frac{\text{Number of swordfish treat}}{\text{Total number of treats}}[/tex]
[tex]\text{Probability of choosing swordfish treat}=\frac{4}{4+10+6}[/tex]
[tex]\text{Probability of choosing swordfish treat}=\frac{4}{20}[/tex]
[tex]\text{Probability of choosing swordfish treat}=0.20[/tex]
Therefore, the probability of choosing swordfish treat is 0.20 or 20%.
[tex]\text{Probability of choosing lizard Lollies}=\frac{\text{Number of lizard lollis}}{\text{Total number of treats}}[/tex]
[tex]\text{Probability of choosing lizard Lollies}=\frac{10}{20}[/tex]
[tex]\text{Probability of choosing lizard Lollies}=0.50[/tex]
Therefore, the probability of choosing lizard Lollies is 0.50 or 50%.
[tex]\text{Probability of choosing puffer pops}=\frac{\text{Number of puffer pops}}{\text{Total number of treats}}[/tex]

Therefore, the probability of choosing puffer pops treat is 0.30 or 30%.

jamaal spent x minutes today practicing his guitar and y minutes today on homework. If the total time he spent on both is 45 minutes or more, which inequality best represents his practice time?
Answers
Jamaal spent x minutes on guitar and y minutes on homework, and the inequality representing his total practice time is x + y ≥ 45.
Explanation:The student, Jamaal, spent x minutes practicing his guitar and y minutes on homework. The fact that he spent 45 minutes or more on both activities combined is represented by the inequality x + y ≥ 45. This inequality states that the sum of the time spent practicing guitar and the time spent on homework is equal to or greater than 45 minutes. To solve this inequality, you would ensure that when you add the minutes spent on each activity, the total does not fall short of 45 minutes, which is the minimum amount of time Jamaal has to spend on these activities.
The inequality representing Jamaal's total practice and homework time is x + y ≥ 45, meaning the total time spent on both activities is at least 45 minutes.
Explanation:Jamaal spent x minutes today practicing guitar and y minutes on homework. If the total time he spent on both activities is at least 45 minutes, the inequality that best represents his practice time is x + y ≥ 45.

Answers
Option: C is the correct answer:
C. 2:3
Step-by-step explanation:The odds in favor of an outcome is the ratio of number of ways the outcome could occur to the number of ways it could not occur.
Here we are asked to find the odds in favor of drawing a green marble.
Hence, it is the ratio of the number of ways the green marble will come up to the number of ways it could not come up.
The probability of drawing a green marble from a marble bag is 40%.
This means that the probability of not drawing a green marble from the bag is: 60%

Jim’s dog weighs 18 pounds 10 ounces. His cat weighs 6 pounds 3 ounces. How many more ounces does Jim’s dog weigh than his cat? PLEASE HELP HARD!
Answers
convert cat and dog's weights to ounces; multiply dog or cat's weight by
16 ounces per pound and then add the additional ounces each weighs
1 pound= 16 ounces
DOG
= (18 pounds * 16 oz/lb) + 10 ounces
= 288 + 10
= 298 ounces
CAT
= (6 pounds * 16 oz/lb) + 3 ounces
= 96 + 3
= 99 ounces
STEP 2:
subtract the difference in the dog's and cat's weights from step 1
= 298 oz dog - 99 oz cat

Hazel eyes = x
Blue eyes = x - 2
Brown eyes = 2(x - 2)

4x - 6 = 34
4x = 40
x = 10
Hazel eyes = x = 10
Blue eyes = x - 2 = 8
Brown eyes = 2(x - 2) = 16
Answer: (a) , (b) , (d)
Out of the given options, the number of students with blue eyes, brown eyes, and hazel eyes can be determined using the information provided in the question.
Explanation:Let's assume the number of students with hazel eyes is x. According to the given information, the number of students with blue eyes is 2 less than x, so it is x - 2. Additionally, there are twice as many students with brown eyes, so the number of students with brown eyes is 2x. The total number of students in the class is given as 34, so we can set up an equation:
x + (x - 2) + 2x = 34
Simplifying this equation, we get 4x - 2 = 34. Adding 2 to both sides, we have 4x = 36. Dividing both sides by 4, we find that x = 9.
Therefore, the number of students with blue eyes is 9 - 2 = 7, the number of students with brown eyes is 2(9) = 18, and the number of students with hazel eyes is 9. Thus, the correct options are a. 8, c. 12, and f. 34.

So the domain is [tex] 0\leq x\leq 10 [/tex]
Answer:
0 ≤ x ≤ 10
Step-by-step explanation:
We cannot take the square root of a negative number. This means we cannot use negative numbers in this equation; this means the lower end is 0.
We can only use x values until the value of the negative square is greater than the value of 10 times the x.
10(1) = 10, which is greater than -(1(1)) = -1.
10(2) = 20, which is greater than -(2(2)) = -4.
10(3) = 30, which is greater than -(3(3)) = -9.
10(4) = 40, which is greater than -(4(4)) = -16.
10(5) = 50, which is greater than -(5(5)) = -25.
10(6) = 60, which is greater than -(6(6)) = -36.
10(7) = 70, which is greater than -(7(7)) = -49.
10(8) = 80, which is greater than -(8(8)) = -64.
10(9) = 90, which is greater than -(9(9)) = -81.
10(10) = 100, which is equal to -(10(10)) = -100. This means this is the cutoff point for this function.
The population of Linton is 12 times as great as the population of Elmore the combined population of both towns is 9,646 people what is the population of Linton
Answers
Since that the population of Linton is 12 times as great as the population of Elmore, then it is considered to be "12x".
Since that the sum of both Elmore and Linton is 9.646, then "X + 12x = 9464" x+12x is 13x , so it should be "13x = 9464". Now, it is easy to find the population of Elmore which is 9464 / 13 = 742. Since that the population of Linton is 12 times the population of Elmore, then the population of Linton is "742 * 12 = 8904".
Final answer:
The population of Linton is 8,904 people, calculated by first finding the population of Elmore (x) and using the fact that Linton's population is 12 times that of Elmore's.
Explanation:
The question involves solving a proportion to determine the population of Linton, given that the population of Linton is 12 times as great as the population of Elmore and that their combined population is 9,646 people.
Let the population of Elmore be represented by x. Therefore, the population of Linton, which is 12 times greater than Elmore's, would be 12x. The combined population of Linton and Elmore, which is given as 9,646, can be represented by the equation:
x + 12x = 9,646
Simplify the equation:
13x = 9,646
Now, divide both sides of the equation by 13 to solve for x:
x = 742
Since we are looking for the population of Linton, we multiply x by 12
12 * 742 = 8,904
Therefore, the population of Linton is 8,904 people.

Find the area. The figure is not drawn to scale
Answers
Answer: The area of the figure is (D) 704 in².
Step-by-step explanation: We are given to find the area of the figure.
We can see that the given figure is a parallelogram with two sets of parallel and congruent sides 22 in and 40 inch. And the height of the parallelogram is 32 in.
The area of a parallelogram with base 'b' units and height 'h' units is given by
[tex]A=b\times h.[/tex]
In the given figure,
base, b = 22 in and height, h = 32 in.
Therefore, the area of the parallelogram is
[tex]A=b\times h=22\times 32=704~\textup{in}^2.[/tex]
Thus, the area f the figure is 704 in².
Option (D) is correct
The parallelogram's area can be found by multiplying the base and height, resulting in 704 in² (option D).
The given figure is a parallelogram with two sets of parallel and congruent sides, measuring 22 inches and 40 inches, and a height of 32 inches. To find the area of the parallelogram, we use the formula A = b * h, where 'b' is the base length and 'h' is the height.
Given:
Base, b = 22 inches
Height, h = 32 inches
Using the formula, the area (A) of the parallelogram is:
A = 22 * 32
A = 704 square inches
So, the area of the figure is 704 square inches. Option (D) is the correct answer.
In conclusion, the parallelogram's area can be found by multiplying the base and height, resulting in 704 in². This confirms that option (D) is the correct answer to the problem.

The vending machine in the school cafeteria usually dispenses about 6 ounces of soft drink. Lately, it is not working properly, and the variability of how much soft drink it dispenses has been gettin greater. The amounts are normally distributed with a standard deviation of 0.2 ounces.
1. What percent of the time will you get between 5.6 and 6.4 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%
2. What percent of the time will you get between 6 ounces and 6.2 ounces?
(a) 13.5%
(b) 34%
(c) 50%
(d) 95%
Answers
#2) B, 34%
Explanation
#1) The mean is 6 and the standard deviation is 0.2. 5.6 is 0.4 away from the mean; 0.4 is 2 standard deviations. 6.4 is 0.4 away from the mean; again, 0.4 is 2 standard deviations.
The empirical rule states that 95% of data will be within 2 standard deviations of the mean, so 95% is our answer.
#2) 6.2 is only 1 standard deviation away from the mean. However, this is only half of the percentage from the empirical rule, since we are only considering numbers larger than the mean. The empirical rule states that 68% of data will fall within 1 standard deviation from the mean, so we have
68/2 = 34%.
The percentage of the time you will get between 5.6 and 6.4 ounces is about 68%, closest to option (b) 34%. The percentage of the time you will get between 6 and 6.2 ounces is 34%, or option (b).
Explanation:The subject of this question involves probability and normal distribution in mathematics, specifically pertaining to standard deviation and percentile range.
For the first question, the range you seek (5.6 to 6.4 ounces) is precisely within one standard deviation (0.2 ounces) both above and below the mean (6 ounces). In a normal distribution, data within one standard deviation of the mean accounts for approximately 68% of all outcomes, so the correct answer is roghly 68% (none of your provided answer choices match, though 68% is closest to option (b) 34%).
For the second question, the range you seek (6 to 6.2 ounces) is within 0.2 ounces above the mean. Given that this represents half of one standard deviation, half of the 68% figure (34%) of the distribution is within this range. So, the correct answer is 34%, which corresponds to option (b).
