Answer:

x1 = -4

x2 = 3

Step-by-step explanation:

[tex]x^{2} + x = 12\\x^{2} +x-12=0\\x^{2} +4x-3x-12=0\\x*(x+4)-3(x+4)=0\\(x+4)*(x-3)=0\\x+4= 0 \\x-3=0\\x=-4 \\x=3\\x1=-4 \\x2=3[/tex]

Step-by-step explanation:

=> x² + x = 12

=> x² + x -12 = 0

=> x² + 4x - 3x -12 = 0

=> x ( x + 4)-3(x + 4) = 0

=> ( x + 4)(x-3)=0

=> x = 3 , -4

Step-by-step explanation:

Hi,

63 = 5x + 18 represents this situation.

63 = 5x + 18

45 = 5x

9 = x

So, the possible number of mins are 1, 2, 3, 4, 5, 6, 7, 8, and 9.

You can also write this as x ≤ 9

I hope this helps :)

Answer: A

Step-by-step explanation:

A) 50/ 45 = 1.111....

B) 65/60 = 1.08333...

C) 99/90 = 1.1

D) 90/120 = .75

Answer:

A

Step-by-step explanation:

Divide each amount by the number of minutes to find the rate per minute. Then multiply by 60 to find the hourly rate. Then compare the hourly rates.

A

$50 / 45 min * 60 = $66.66/hour

B

$65 / 1 hour = $65/hour

C

$99 / 90 min * 60 = $66/hour

D

$90 / 2 hours = $45/hour

Answer: A

Answer:

(3 x 10^3) / (12 x 10^6) = 0.00025

Answer:

15 cm

Step-by-step explanation:

Since the square's side length is 8 cm, and one of its sides is the short leg of the triangle, the short leg of the triangle is 8 cm

Using the pythagorean theorem, solve for b (the missing side length x)

a² + b² = c²

8² + b² = 17²

64 + b² = 289

b² = 225

b = 15

So, the missing side length is 15 cm

Step-by-step explanation:

a function that describes a set of points in Cartesian space by mapping each x-coordinate to a y-coordinate, then a circle cannot be described by a function because it fails what is known in High School as the vertical line test. A function, by definition, has a unique output for every input.

Answer: 0.0188

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the standard deviation of the sampling  distribution of p is 0.0144.

In this problem:

Then, the standard deviation is:

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{1012}} = 0.0144[/tex]

The standard deviation of the sampling  distribution of p is 0.0144.

Answer:

d = 15.8 m

Step-by-step explanation:

Apply the Pythagorean Theorem to find the length of the diagonal.  The correct equation for this particular rectangle is

d = √(9² + 13²) = √250 = √25·√10 = 5√10

To the nearest tenth, this comes to d = 15.8 m

Answer:

As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

Step-by-step explanation:

As the standard deviation for the past due amounts is 63

The sample size n= 67

1) Formulate the null and alternate hypothesis

H0: u ≤ 23 against the claim Ha: u > 23

2)  The test statistics is

Z= x- u / σ/ √n

z= 20- 23/ 63/ √67

z= 0.00581

z= 0.006

3) The significance level ∝= 0.1

4) The critical value for ∝= 0.1 is Z > ±2.33

5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

Answer:

D. 5

Step-by-step explanation:

Based on the midsegment theorem of a trapezoid, thus:

QR = ½(OP + MN)

Substitute

27 = ½((5x - 7) + (6x + 6))

27 = ½(5x - 7 + 6x + 6)

Add like terms

27 = ½(11x - 1)

Multiply both sides by 2

2*27 = 11x - 1

54 = 11x - 1

54 + 1 = 11x

55 = 11x

55/11 = x

Answer:

Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}

Step-by-step explanation:

Let regular non discounted price of 7 pizzas be x

x - 22.5 = 82.5

x = 82.5 + 22.5

x = 105 (Regular Non discounted price of 7 pizzas)

Regular Price of 7 pizzas = 105

Regular price of 1 pizza = 105 / 7 = 15
