Answer:

**Answer: It takes him 1 minute and 25 seconds**

**Step-by-step explanation:**

**5 divided 4**

**4 times 1 = 4**

**5-4=1**

**put the decimal and make 1=10 Ans.: 1.25**

**4 times 2 = 8**

**10-8=2**

**put the 0 = 20**

**4 times 5 =20**

**20-20=100**

The following dot plot shows the number of cavities each of Dr. Vance's 63 patients had last month. Each dot represents a different patient. Which of the following is a typical number of cavities one patient had?

**Answer:**

The value of x any y are "**-5.29 and 0.79**" and "**3.79 and -2.29**"

**Step-by-step explanation:**

**Given values:**

**After solve equation (a) we get**

**After solve equation (b) we get**

**put the value of x in to equation (x)**

The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29

**Answer:**

D Edg

**Step-by-step explanation:**

all real numbers except 2 and 4

**Answer: **(-∞, 2)∪(2, 3]∪(4, ∞)

**Step-by-step explanation:**

Domain is the allowed x values in the function. The numerator, x + 1 will be defined for all numbers. But that fraction wont be, the minute that fractions denominator is equal to zero, your entire function becomes undefined.

So lets figure out what number will make this undefined. Then we'll know the functions domain is everywhere but that x value.

Make x^2 - 6x + 8 = 0

What two numbers multiply to equal +8 but add to equal -6? Thats -4 and -2.

(x - 4)(x - 2) = 0 This means the function is undefined when x equals 4 and 2

(-∞, 2)∪(2, 3]∪(4, ∞)

**Step-by-step explanation:**

(2x-y+3)(2x-y-3)=

4x²-2xy-6x-2xy+y²+3y+6x-3y-9=

4x²-4xy+y²-9=

(2x-y)²-9

the solution.

Willow must work

hours this week.

Multiply the number of hours worked (h) by earnings per hour $10 to get

10h

This needs to be more than ( Greater than) 200

Now you have 10h > 200

Solve for h by dividing both sides by 10:

h >20

This means she needs to work more than 20 hours this week.

**Answer:**

10h=200

h=20

**Step-by-step explanation:**

**10h=200**

**10h/10=200/10**

**h=20**

**Answer:**

cool

**Step-by-step explanation:**

The **distance **covered by the **train **in 3.5 **seconds **will be 1575 **feet**.

The **distance **covered by the **particle **or the body in an **hour **is called speed. It is a **scalar quantity**. It is the **ratio **of distance to time.

We know that the **speed **formula

Speed = Distance/Time

A **train **travels 45 **feet **in 1/10 in a **second**.

Then the **speed **will be

Speed = 45 / (1/10)

Speed = 45 x 10

Speed = 450 feet per second

The **distance **covered by the **train **in 3.5 **seconds **will be

Distance = 450 x 3.5

Distance = 1575 feet

More about the **speed **link is given below.

#SPJ2

**Answer:**

1575 ft

**Step-by-step explanation:**

Convert 1/10 to decimal to make the math simpler.

1/10 = 0.1

Divide 3.5 by 0.1.

3.5/0.1 = 35

Multiply 35 by 45.

35 × 45 = 1575

The train will travel 1575 feet in 3.5 seconds.
