q(x)= 1/2x - 3; q(x) =-4. Find the value of x

Answers

Answer 1

Answer:

[tex]q(x) =-5[/tex]

Step-by-step explanation:

I am solving this using Function Notation.

We are given:

[tex]q(x)= \frac{1}{2}x - 3[/tex]

While we are to find:

[tex]q(x) =-4[/tex]

In Function Notation, replace all the "[tex]x[/tex]" you see with the value you are given.

So, in this case,

[tex]q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}x - 3[/tex]

Would become

[tex]q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}(-4) - 3[/tex]

Now we can solve.

[tex]\frac{1}{2}(-4) - 3[/tex]

Use PEMDAS; Parenthesis first;

[tex]\frac{1}{2}(-\frac{4}{1})[/tex]

Cross divide: 1 cancels 1, -4 ÷ 2 = -2

Hence, we are left with

[tex](-2) - 3[/tex]

[tex]-5[/tex]

Therefore, the value of x is -5

6. What is the value of x in the solution to the systems of linear equations shown below?
2x - 2y+z=3
5y-z= -31
x+ 3y + 2z = -21

Answers

Step-by-step explanation:

[tex]1) \: \: 2x - 2y + z = 3 \\ 2x = 3 + 2y - z \\ x = \frac{3 + 2y - z}{2} \\ \\ 2) \: \: \: not \: any \: \: \: x \: \: \: available \: \: \\ \\ 3) \: \: x + 3y + 2z = - 21 \\ x = - 21 - 3y - 2z[/tex]

Answer:

x= -5

Step-by-step explanation:

5y-z= -31, add z and 31 to both sides

5y+31 = z, substitute z in the other two given equations

2x - 2y+z=3

2x-2y +5y+31 = 3, combine like terms and subtract 31 from both sides

2x+3y = -28

x+ 3y + 2z = -21

x+3y +2(5y+31) = -21, distribute 2 over the addition parenthesis

x+3y +10y+62 = -21, combine like terms and subtract 62 from both sides

x+13y = -83

Now we have 2 equations  with 2 variables x and y to solve

2x+3y = -28

x+13y = -83

Because we need to find x then from the first equation we can write that

3y = -2x-28, subtract 2x from both sides and the divide both sides by 3

y = (-2x-28)/3, substitute this in the second equation

x + [13(-2x-28)/3] = -83 , distribute 13 . over the subtraction parenthesis

(3x/3)+[(-26x - 364) /3= -83, find the common denominator

3x+[(-26x - 364) = -83*3 , cross multiply

3x -26x = -249 +364, add 364 to both sides

- 23x = 115, divide both sides by (-23)

x= -5

Three friends participated in a "Biggest Loser" weight loss competition. The table below shows their starting weight and the weight after two months:


Starting Weight

Weight After Two Months

Jacob

225 pounds

207 pounds

Timothy

200 pounds

188 pounds

Hamza

280 pounds

259 pounds



Who lost the biggest percentage of his starting weight?



You need to find the percentage of weight loss for each participant.



To find the percentage of weight loss use the formula



Starting weight – Weight after two months x 100

Starting Weight

Answers

Answer:

Jacob lost the biggest percentage of his starting weight.

Jacob: 8%

Timothy: 6.4%

Hamza: 7.5%

Formula: (initial weight - new weight)/initial weight times 100.

Step-by-step explanation:

Jacob: 225 pounds - 207 pounds = 12 pounds

x/100 = 12/225

= 1800/225

= 8%

Timothy: 200 pounds - 188 pounds = 12 pounds

x/100 = 12/188

= 1200/188

= 6.4%

Hamza: 280 pounds - 259 pounds = 21 pounds

x/100 = 21/280

= 2100/280

= 7.5%

For thousands of years, ice cream has been a decadent dessert loved by most people around the world.There is some argument about who first invented ice cream. Some believe that ice cream was invented by the Chinese people anywhere from 2,000 to 6,000 years ago. They created a recipe of frozen milk and rice that was served as a dessert. Persia has also been credited with first serving frozen desserts. Over 2,000 years ago, the wealthy people of Persia enjoyed shaved ice from the mountains, covered with grape juice. They later learned to freeze rosewater and add different fruit toppings. These desserts were considered delicacies that only the richest families could experience. About 1,000 years after this, there is evidence that suggested Nero, the Roman Emperor, also enjoyed frozen treats and demanded that a constant supply of ice from the mountains be available to him. He liked to add honey to the top of his dessert.Ice cream as we know it can be traced back to the 9th century in Arab cities, such as Baghdad, Damascus, and Cairo. Near the end of the 13th century, Marco Polo returned to Italy after his travels through China with news of a frozen creamed dessert. In Europe, ice cream could only be found in Italy. Then, in 1533, Italian noblewoman Catherine de'Medici of Italy married Henry II of France. As Queen, Catherine introduced ice cream to France. Soon, the popularity of the dessert spread across all of Europe.Why is there an argument about who really invented ice cream?a: Ice cream wasn't created until the ice cream cone was invented. b: Many people around the world disagreed about which flavor of ice cream would be recognized as the first. c: Only wealthy people were given credit for inventing ice cream. d:There were many people from different places experimenting with frozen desserts around the same time.
