solve the equation. x^2+49=0
a.) no real solution.
b.) x= 7
c.) x= -7
d.) x= -7 and x= 7

Answers

Answer 1

Answer:

C

Step-by-step explanation:

-7 squared is -49, -49 plus 49 is 0.

Answer 2
(-7)^2=49 and 7^2=49
No matter what you plug in for x, squaring it will make it come back positive. Therefore it will be impossible to get -49+49=0. So there is no solution.

a) no real solution

Answer:

w(15)=112.5

Step-by-step explanation:

All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.

In this case, you make the equation w(15)=7.5(15) which you can rewrite as

                                                                                  w(15)= 7.5×15, which gives                        .                                                                                  you 112.5 as the product.

You will multiply both by 5 to get 20

So 3×5 is 15

20+15 = 35

Answer: 35 students

Explanation: Divide 4 into 20 to see how many sets of 4 girls there are. So there are 5 sets of four girls.

Five times three is 15.

In total (15 + 20), there are 35 students.

Which of these equations, when solved, gives a different value of x than the other three? 9.1 = -0.2x + 10 10 = 9.1 + 0.2x 10 – 0.2x = 9.1 9.1 – 10 = 0.2x To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining. Which equations could you use to find the price of one tire patch? Select all that apply. 4x – 1.9 = 22.2 4x – 22.2 = 1.9 4x + 1.9 = 22.2 4x + 22.2 = –1.9 22.2 – 4x = 1.9

Answers

Given:

Different equations are given.

Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan's gift card had $1.90 remaining.

To find:

The equation which gives a different value of x than the other three.

To find the equations that could you use to find the price of one tire patch.

Solution:

In option A,

[tex]9.1 = -0.2x + 10[/tex]

[tex]0.2x= 10-9.1[/tex]

[tex]0.2x= 0.9[/tex]

Divide both sides by 0.2.

[tex]x=\dfrac{0.9}{0.2}[/tex]

[tex]x=4.5[/tex]

Similarly,

In option B,

[tex]10 = 9.1 + 0.2x[/tex]

[tex]0.9= 0.2x[/tex]

[tex]4.5=x[/tex]

In option C,

[tex]10-0.2x = 9.1[/tex]

[tex]-0.2x = -0.9[/tex]

[tex]x = 4.5[/tex]

In option D,

[tex]9.1 – 10 = 0.2x[/tex]

[tex]-0.9 = 0.2x[/tex]

[tex]-4.5 = x[/tex]

Since option D has difference solution, therefore the correct option is D.

Let price of one tire patch be x.

So, price of 4 tire patches = 4x

Remaining amount in Rhyan's gift card = $1.90

Total amount = $22.20

Price of 4 tire patches + Remaining amount in gift card = Total amount

[tex]4x+1.9=22.2[/tex]

It can be written as

[tex]4x-22.2=-1.9,1.9=22.2-4x,22.2-4x=1.9[/tex]

Therefore, the correct options are C and E.

Mike sold half of his comic books and then bought 8 more. He now has 18. How many did he begin with? what is the impact of the word connotation, in the giver? Parkour is thought by many to be an extreme sportespecially when people see parkour practitioners (known as traceurs) climbing walls and jumping off buildings. However, it might be better to characterize parkour as a radical art form involving both the body and mind. Although this art form can be extreme, it does not involve the teamwork, structure, or competitiveness of organized sports. In addition, traceurs can be difficult to recognize, as they do not wear matching uniforms to identify themselves. Parkour and its practitioners are in a category of their own. The ultimate goal of parkour is for a person to mentally and physically prepare to overcome any obstacle he or she may face. Traceurs, who pit their bodies against various types of obstacles, often risk physical injury, and safety is an important concern. While practicing parkour, a traceur's route may take him or her over a large boulder, across several rooftops, or across the top of a wall. As dangerous as these acts may sound, most traceurs do attempt to learn the safest way to move, jump, and land. Parkour has become a popular art form in urban settings around the world due to the many obstacles located around the cityscape. This has led to concerns for traceurs' safety, as well as worries about traceurs trespassing on private property and attempting to jump from high buildings. As in most physical activities, safety for oneself and others should be paramount in the practice of parkour.Which sentence best states the main idea of the first paragraph? A. Parkour is only dangerous when traceurs are not careful. B. Parkour does not have many practitioners around the world. C. Parkour is a reinvention of the classic form of extreme sports. D. Parkour does not have much in common with extreme sports. How would this passage be different if it was told entirely from Harboro's point of view?1.
