Log(x + y) - logx = logx

By laws of logarithm, logA - logB = log(A/B)

log(x + y) - logx = log((x +y)/x)

log((x +y)/x) is not equal to log x.

So the statement:

log(x + y) - logx = logx is**False.**

Hope this helps.

False. That is not how properties of logs works. log(xy)=logx+logy, not log(x+y)=logx+logy.

Question

Which is shorter 3/6 of a minute or 2/6 of an hour

Solution 1

3/6 of a minute because an hour is much longer

Solution 2

3/6 of a minute which is 30 seconds

Question

the width of a rectangle is 3 inches less than its length.the perimeter is 130 inches.Whats the dimension of the rectangle

Solution 1

L=w+3

P=2l + 2w

2l= 2w+6

130=4w+6

-6 -6

124 = 4w

31= w

width= 31 length = 34

P=2l + 2w

2l= 2w+6

130=4w+6

-6 -6

124 = 4w

31= w

width= 31 length = 34

Question

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile traveled. The rule c =0.20m + 2.00 describes the relationship between the number of miles m and the total cost of the ride c. What is the charge for a 2.7 mile ride?

Solution 1

c =0.20m + 2.00

Where c is the cost and m = number of miles,

For a 2.7 mile ride, m = 2.7

c = 0.20m + 2.00, m = 2.7

c = 0.20*2.7 + 2

c = 0.54 + 2

c = 2.54

Charge for the ride =** $2.54**

I hope this helps.

Where c is the cost and m = number of miles,

For a 2.7 mile ride, m = 2.7

c = 0.20m + 2.00, m = 2.7

c = 0.20*2.7 + 2

c = 0.54 + 2

c = 2.54

Charge for the ride =

I hope this helps.

Solution 2

It should give you 2.54.

First, you have to multiply 2.7 miles times .20 miles. It gives you .54, which you are supposed to add 2.00 to it for every ride.

Question

Is this how you solve x + y = -4?
x - x + y = -4 - x
y = -4 - x

Solution 1

Yes, you can also write it as y=-x-4

Solution 2

Well theres calulator soup it teaches you alot im not so sure about the anwers but ill help in anyway

Question

Mr. Grant's credit card bill was $2,684.72. If he has already paid off $1,865.24 of the amount due, how much more does he have to pay? $817.48 $819.48 $821.41 $822.48 $825.41

Solution 1

**Answer:**

**The Mr. Grant has to pay $819.48 more.**

**Step-by-step explanation:**

Given : Mr. Grant's credit card bill was $2,684.72. If he has already paid off $1,865.24 of the amount due.

We have to find the amount left to pay.

Since, Total credit card bill of Mr. Grant was $2,684.72

And he paid amount $1,865.24

Total amount left = Total amount - Total paid amount

Total amount left =$2,684.72 - $1,865.24

**Total amount left = $819.48**

**Thus, The Mr. Grant has to pay $819.48 more. **

Solution 2

819.48

You have to substract 1,865.24 from 2,684.72.

You have to substract 1,865.24 from 2,684.72.

Question

What is true of the function g(x) = –2x2 + 5? g(x) is the multiplication of g and x.
–2x2 +5 is the input of the function.
The variable x represents the independent variable.
The variable g represents the input of the function.

Solution 1

**Answer:**

**3. The variable x represents the independent variable. **

**Step-by-step explanation:**

We are given the function, .

So, according to the options, we have,

**1.** As g(x) represents a function. So, g(x) is **not **the multiplication of g and x.

**2.** As the value is the output value. So, it is **not** the input value.

**3.** The variable x is an independent variable.

**4.** As, the variable g is the output value. So, it is **not** the input value of the function.

Hence, the true statement for the given function is,

**3. The variable x represents the independent variable. **

Solution 2

The answer is **"C"** The variable x represents the independent variable. I hope this helps sorry if it was a little late.

Question

A right angled triangle has sides 3 cm and 8cm respectively less than its hypotenuse. Find the lenght of hypotenuse to nearest milimeter

Solution 1

**Length** of the **hypotenuse** of a** right angled triangle **is equals to **85millimeter (nearest mm).**

" A **right angled triangle** is a polygon with three sides , three vertices and three angles enclosed in it, with one of the **angle** equals to 90°."

**Formula used**

**Pythagoras theorem**

**(Hypotenuse)² = (side one)² + ( side two )²**

**Value used**

**1cm = 10mm**

According to the question,

Given,

In a **right angled triangle**

Side one = 3cm

Side two = 8cm

Substitute the value in the formula we get,

(**Hypotenuse**)² = (3)² + (8)²

⇒**(Hypotenuse**)² = 9 + 64

⇒(**Hypotenuse**)² = 73 cm²

⇒(**Hypotenuse**)²= 7300mm²

⇒ **Hypotenuse** = √7300

= 85.44mm

≈ **85 mm( nearest mm)**

Hence, **Length** of the **hypotenuse** of a** right angled triangle **is equals to **85millimeter (nearest mm).**

#SPJ2

Solution 2

3cm= 30mm

8cm= 80mm

c^2 = a^2 + b^2

= 30^2 + 80^2

= 7300

c= square root of 7300

= 85.44003745

= 85mm

Hope this helps!

8cm= 80mm

c^2 = a^2 + b^2

= 30^2 + 80^2

= 7300

c= square root of 7300
