Which of the following is NOT a solution to the system of inequalities?

a. (0, 4)
b. (1, 2)
c. (2, 1)
d. (1, 5)

Answer:

76%

Step-by-step explanation:

First do 700 - 168 which is 532

Next we see that 700 is 100% in this scenario

Then we will use the value we seek as ‘x’

So, x% = 532

We can put the two equations, 100%/x% = 700/532

they both have LHS

We can take the inverse from both sides yields

Therefore, the answer is 76%

Answer:

V ≈ 160 ft³

Step-by-step explanation:

V = [tex]\frac{\pi r^2h}{3}[/tex] ( r is the radius and h the height )

Here the diameter = 8 then r = 8 ÷ 2 = 4 and h = 10 , then using π ≈ 3

V ≈ [tex]\frac{3(4)^2(10)}{3}[/tex] ( cancel 3 on numerator/ denominator )

   = 4² × 10

   = 16 × 10

   = 160 ft³

Answer:

The factored form of the quadratic expression 2x³ + 4x² - x is x(2x² + 4x - 1).

The correct option is D.

The greatest number can divide the numbers into equal parts.

It is called the greatest common factor.

To factor 2x³ + 4x² - x, we can first factor out the greatest common factor, which is x:

2x³ + 4x² - x = x(2x² + 4x - 1)

Now, we need to factor the quadratic expression 2x² + 4x - 1. We can use the quadratic formula to find its roots:

x = (-b ± √(b² - 4ac)) / 2a

where a = 2, b = 4, and c = -1:

x = (-4 ± √(4² - 4(2)(-1))) / 2(2)

x = (-4 ± √(20)) / 4

x = (-4 ± √(5)) / 4

x = (-2 ± √(5)) / 2

Therefore, the factored form of 2x³ + 4x² - x is:

2x³ + 4x² - x = x(2x - (-2 + √(5)))(2x - (-2 - √(5)))

Answer:

(1 gallon)/(100 ft^2)

Step-by-step explanation:

(1 gallon)/(100 ft^2) is a good conversion factor.  We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:

(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons  [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.

Answer:

Step-by-step explanation:

Equating the expressions for y will give a quadratic in x:

  4x^2 +x = 3x +5

  4x^2 -2x = 5 . . . . . . collect x-terms on the left

  4(x^2 -1/2x) = 5 . . . .factor out the leading coefficient

  4(x^2 -1/2x +1/16) = 5 4/16 . . . . complete the square

  4(x -1/4)^2 = 84/16 . . . . write the quadratic as a square

  x -1/4 = (±√21)/4 . . . . . divide by 4 and take the square root

  x = (1 ±√21)/4 . . . . . . . add 1/4

  y = 3x +5 = 3(1 ±√21)/4 +5 = (23 ±3√21)/4 . . . . use the linear equation for y

The solutions are ...

  x = (1 -√21)/4; y = (23 -3√21)/4 ≈ 2.31

  x ≈ -0.89, y ≈ 2.31

  x = (1 +√21)/4; y = (23 +3√21)/4

  x ≈ 1.40, y ≈ 9.19

Answer:

  48°, 53°, and 79°

Step-by-step explanation:

The sum of angles of a triangle is 180 (degrees), so you have ...

  2x +(2x +5) +(3x +7) = 180

  7x +12 = 180

  7x = 168

  x = 24

Then the measures of the angles are ...

  2(24) = 48

  2(24) +5 = 53

  3(24) =7 = 79

The angles are 48°, 53°, and 79°.

Answer:

2.5

Step-by-step explanation:

X × 3=7.5

divide by 3

x=2.5

The required equation to describe the situation is x × 3 = 7.5, and the number is 2.5.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation to describe the situation is:

x × 3 = 7.5

Where x is the number.

This equation states that the product of a number (x) and 3 is equal to 7.5. This equation can be read as "x multiplied by 3 equals 7.5."

To find the value of x, we can solve for x by dividing both sides of the equation by 3:

x = 7.5/3

x = 2.5

So, the number is 2.5.

You can check this by substituting the value of x back into the equation:

x × 3 = 7.5

2.5 × 3 = 7.5

7.5 = 7.5

So, it holds true.

Answer:

△ABC is similar to △JEL by ​AA Similarity Postulate​.

Step-by-step explanation:

First, find out the y-intercept(s).

For 5, it is 6. For 6, it is 150. For 7, it is 20. For 8, it is 0.

Now we need to find the slopes.

For 5, it goes down one and right 2, so it would be -1/2 (rise/run).

For 6, it goes up 100 and right 2, so it would be 100/2 (rise/run) or 50.

For 7, it goes up 10 and right 3, so it would be 10/3 (rise/run).

For 8, it goes up 25 and right 1, so it would be 25/1 (rise/run) or 25.

Then you plug into the equation: y = mx + b

5: y = -1/2x + 6.

6: y = 50x + 150.

7: y = 10/3 + 20.

8: y = 25x + 0 which would be y = 25x (since add 0 is useless).
