Solve for x..........

Answer:

11.1%

Step-by-step explanation:

percentage decrease is calculated as

[tex]\frac{decrease}{original}[/tex] × 100%

decrease = 18 - 16 = 2 , then

percent decrease = [tex]\frac{2}{18}[/tex] × 100% = 11.1% ( to the nearest tenth )

Answer:

Jenny drove for about 4.93 hours

Step-by-step explanation:

Jenny uses 7/9 gallons of gas per hour.

She used a total of 3 5/6 gallons.

If x is the number of hours she drove, then she used 7x/9 gallons.

X* 7/9 = 3 5/6

3 5/6 can be converted to an improper fraction.

((3*6)+5) / 6 = 23/6 gallons

=> x * 7/9 = 23/6

=> x = (23/6) / (7/9)

=> x = (23/6) * (9/7)

=> x = 69/14

=> x = 4.928571429 hours.

The rate of change  is the same amount of meat from Thursday to Friday is 14 Kilograms of meat

Here, the line graph shows the amount of meat in kilograms fed to the lions on each day of the week.

From the line graph the amount of meat fed to the lines on Thursday is 58 kilograms

And the amount of meat fed to the lines on Thursday is 72 kilograms

Let x represents the rate of change in the amount of meat from Thursday to Friday.

So, the value of x would be,

x = 72 - 58

x = 14 kilograms

Thus, the rate of change in the same amount of meat are fed to the alliance between Thursday and Friday = 14 kilograms

Discriminant:  in mathematics, a parameter of an object or system calculated as an aid to its classification or solution.

Answer: Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2

Step-by-step explanation:

Answer:

It makes more sense to apply the zero product property on x² + 11x + 30 = 0.

Step-by-step explanation:

The zero product property simply states that if ab = 0, then a = 0 or b = 0 or both are zeros.

Given 4x² – 2 = 15, 2x² + 2x – 9 = 0, x² + 11x + 30 = 0, x² + 2x = 119; let's see which of the above is easiest to apply the zero product property.

1. 4x² – 2 = 15

4x² – 2 – 15 = 0

4x² – 17 = 0

It's not so easy to express the result as a product equal to zero.

2. 2x² + 2x – 9 = 0

This is not factorisable easily and can't be expressed as a product equal to zero easily.

3. x² + 11x + 30 = 0

This is factorisable easily. On factorising we have:

x² + 5x + 6x + 30 = 0

(x + 5)(x + 6) = 0. The zero product property can be applied here easily since x = 5 or x = 6 or both.

4. x² + 2x = 119

x² + 2x – 119 = 0

This is not easily factorisable and cannot be expressed easily as a product equal to zero.

Therefore, it makes more sense to apply the zero product property on

x² + 11x + 30 = 0

Answer:

x=-2

Step-by-step explanation:

Answer:

The numbers can be written as x and x + 1. Set the product of the numbers equal to 1,332 to get x(x + 1) = 1,332. You can solve the quadratic equation by using the quadratic formula, completing the square, or factoring. When you solve the quadratic equation, you find that x = –37 and 36. Since the question asked for positive integers, the only viable solution is x = 36. To solve for the larger integer, you add 1 to 36 to get an answer of 37.

Step-by-step explanation:

sample response

The first consecutive number is 36 and the second consecutive number is 37.

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers.

Let the first consecutive number be x and the second consecutive number be (x+1).

The product of two consecutive positive integers is 1,332.

[tex]\rm x\times (x+1)=1332\\\\x^2+x=1332\\\\x^2+x-1332=0\\\\x^2+37x-36x-1332=0\\\\x(x+37)-36(x+37x)=0\\\\(x+37)(x-36)=0\\\\x+37=0, \ x=-37\\\\x-36=0, \ x=36[/tex]

(Ignoring the negative value of x).

The first consecutive number = x = 36

The second consecutive number = x+1 = 36 + 1 = 37

Hence, the first consecutive number is 36 and the second consecutive number is 37.

Answer:

Number of onion rings in the combination = x = 6

Number of sliders in the combination = y = 2

Step-by-step explanation:

At a particular restaurant, each onion ring has 45 calories and each slider has 325 calories. A combination meal with onion rings and sliders is shown to have 920 total calories and 3 times as many onion rings as there are sliders. Write a system of equations that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.

Let

Number of onion rings in the combination = x

Number of sliders in the combination = y

45x + 325y = 920 (1)

3 times as many onion rings as there are sliders

x = 3y (2)

Substitute x = 3y into (1)

45x + 325y = 920

45(3y) + 325y = 920

135y + 325y = 920

460y = 920

y = 920/460

y = 2

Substitute y = 2 into (2)

x = 3y

x = 3(2)

x = 6

Number of onion rings in the combination = x = 6

Number of sliders in the combination = y = 2
