What are the solutions of the system? y=6x+6y=−x2+5x+6
Answer:
Given the system of equations:
[tex]y = 6x+6[/tex] .....[1]
[tex]y = -x^2+5x+6[/tex] .....[2]
Equate these two equations we have;
[tex]-x^2+5x+6 = 6x+6[/tex]
Subtract 6 from both sides we have;
[tex]-x^2+5x= 6x[/tex]
Subtract 6x from both sides we have;
[tex]-x^2-x= 0[/tex]
⇒[tex]-x(x+1) = 0[/tex]
By zero product property we have;
⇒x = 0 and x+1= 0
⇒x = 0 and x=-1
Substitute these values in [1] we have;
For x = 0
y = 6(0)+6 = 6
for x = -1
y =6(-1)+6 = -6+6= 0
Therefore, the solutions of the given systems are, (0, 6) and (-1, 0)

I need to increase my sales by 35% this month I’m currently at 45 sales how many sales do I need to meet my goal ?
Answer:
61 sales.
Step-by-step explanation:
Let x represent present sales.
We have been given that you need to increase your sales by 35% this month. You are currently at 45 sales.
To find the number of sales to meet the goal, we will find 35% of 45 and add to 45 as:
[tex]\text{The number of sales to meet the goal}=45+\frac{35}{100}*45[/tex]
[tex]\text{The number of sales to meet the goal}=45+0.35*45[/tex]
[tex]\text{The number of sales to meet the goal}=45+15.75[/tex]
[tex]\text{The number of sales to meet the goal}=60.75[/tex]
[tex]\text{The number of sales to meet the goal}\approx 61[/tex]
Therefore, you need to make 61 sales to meet you goal.
kim has a scale drawing of a car with a scale of 1 in : 3 ft. what is the scale factor
Final answer:
The scale factor for the scale drawing of a car with a scale of 1 inch : 3 feet is 1:36, or the fraction 1/36.
Explanation:
The student has a scale drawing of a car with a scale of 1 inch : 3 feet. To find the scale factor for this drawing, you need to convert feet into inches since the scale is given in inches to feet. There are 12 inches in a foot, so 3 feet is the same as 36 inches. Therefore, the scale for the car drawing is 1 inch on the drawing for every 36 inches of the actual car.
The scale factor is the ratio of the dimension in the drawing to the actual dimension of the object. In this case, the scale factor is 1:36, which can be written as the fraction 1/36. This means that every inch on the scale drawing represents 36 inches on the actual car.

(06.02)A six-sided number cube labeled 1 through 6 is rolled 500 times. An odd number is rolled 325 times. Compare the experimental probability of rolling an odd number with the theoretical probability of rolling an odd number and select one of the statements below that best describes the situation.
The experimental probability and theoretical probability are the same.
The experimental probability is larger than the theoretical probability.
The experimental probability is smaller than the theoretical probability.
There is not enough information to determine the relative frequency.
Answer: Second option is correct.
Step-by-step explanation:
Since we have given that
Number of times a die rolled = 500
Number of times an odd number occurs =325
so, the experimental probability would be
[tex]\dfrac{325}{500}\\\\=0.65[/tex]
And we know that
Number of outcomes in a die = 3
Number of total outcomes = 6
So, The theoretical probability would be
[tex]\dfrac{3}{6}=\dfrac{1}{2}=0.5[/tex]
So, The experimental probability is larger than the theoretical probability.
Hence, Second option is correct.

0 is greater than or equal to 7n
Final answer:
To solve the inequality 0 is greater than or equal to 7n, divide both sides by 7 to get n ≤ 0. This implies n can be any number less than or equal to zero.
Explanation:
The question asks us to solve the inequality 0 is greater than or equal to 7n. This involves understanding inequalities and basic algebraic manipulation. To solve for n, we divide both sides of the inequality by 7, keeping in mind the rules regarding dividing by a positive or negative number. Since 7 is positive, the direction of the inequality remains the same. Thus, we get n ≤ 0.
This means that n can be any number less than or equal to zero for the inequality to be true. It's an important fundamental of algebra that assists in understanding how to work with inequalities and solve them correctly.

If were to walk 15 miles today and stoped every 0.5 how many stops will I stop and rest?
If i= √-1 what is the value of i^3
Final answer:
To calculate i^3, we use the powers of i, where i = √-1. We find that i² = -1, and thus i³ = i² × i = -1 × i = -i.
Explanation:
The value of i to the power of 3, denoted as i3, can be determined by understanding the fundamental properties of the imaginary unit i, where i is defined as i = √-1. To find i3, we start by considering the powers of i:
i1 = i,
i2 = -1,
i3 = i2 × i = -1 × i = -i,
i4 = (i2)2 = (-1)2 = 1.
Therefore, the value of i3 is -i.

Which of the following statements is true? A 15 kg box has more inertia than a 10 kg box. Forces occur in equal and opposite force pairs. Objects in motion will keep moving at the same velocity unless acted upon by an outside force. All of the above.
Answer:
All of the above
Step-by-step explanation:
A 15 kg box has more inertia than a 10 kg box. --TRUE
Inertia is a property of matter related to its mass. The more mass an object has, the greater its inertia. S o the statement is correct since 15 kg is greater in mass than 10 kg therefore it has more inertia.
Forces occur in equal and opposite force pairs. -- TRUE
This statement is correct and is known as Newton's third law. Which tells us that for every force of action there is a reaction force that is equal in magnitude but opposite in direction.
Objects in motion will keep moving at the same velocity unless acted upon by an outside force. -- TRUE
This is Newton's first law of motion, it tells us that an object will retain its state of rest or movement as long as there is no resulting force or external force acting on it.

What plus what equals 24
Final answer:
Different pairs of numbers can add up to 24.
Explanation:
The sum of two numbers that equals 24 depends on the specific values of the two numbers. However, here are a few examples:
12 + 12 = 24
20 + 4 = 24
15 + 9 = 24
These examples show that different pairs of numbers can add up to 24. The sum can be found by adding the two numbers together.
Laticia randomly selected 25% of the seventh grade students in her school and asked them their favorite season. Of the students surveyed, 51 chose summer as their favorite season. Based on the data, what is the most reasonable prediction of the number of seventh grade students in her school who would choose summer as their favorite season?
A) 15
B) 75
C) 150
D) 200
The most reasonable prediction of the number of seventh grade students in her school who would choose summer as their favorite season is 75.
To predict the number of seventh-grade students in Laticia's school who would choose summer as their favorite season, we can use the fact that she surveyed 25% of the seventh-grade students and found that 51 of them chose summer.
First, we need to find out how many seventh-grade students there are in total. Since Laticia surveyed 25%, we can set up a proportion:
[tex]\[\frac{51}{25\%} = \frac{x}{100\%}\][/tex]
Solving for x, the total number of seventh-grade students, we get:
[tex]\[x = \frac{51 \times 100\%}{25\%} = 204\][/tex]
Now, since 51 students chose summer as their favorite season out of 204 seventh-grade students, to find out how many students might choose summer if all seventh-grade students were surveyed, we can set up another proportion:
[tex]\[\frac{51}{204} = \frac{y}{100\%}\][/tex]
Solving for y, the number of students who might choose summer if all seventh-grade students were surveyed:
[tex]\[y = \frac{51 \times 100\%}{204} = 25\%\][/tex]
This comes out to (y = 51), which means if all seventh-grade students were surveyed, we could reasonably predict that 51 of them would choose summer as their favorite season. Therefore, option B) 75 is the most reasonable prediction.
