One of these expressions reduces to 1 and the
other reduces to -1. Do you know which one is
which? How do you know?

1)

2x - 3y = - 1

For y = x - 1

So,

2x - 3y = - 1, Subsitution

2x - 3(x - 1) = - 1

2x - 3x + 3 = - 1

- x + 3 = - 1

- x = - 1 - 3

- x = - 4

x = 4 ✔

y = x - 1

y = 4 - 1

y = 3 ✔

So => HP = {x, y} = {4, 3}

Answer:

12(p+4)

Step-by-step explanation:

The greatest common factor of expressions is the highest divisor that can divide both expressions

The equivalent expression of  12p+48 is 12(p - 4)

The expression is given as:

[tex]\mathbf{12p + 48}[/tex]

Express 48 as 12 * 4

[tex]\mathbf{12p + 48 = 12p - 12 \times 4}[/tex]

Express 12p as 12 * p

[tex]\mathbf{12p + 48 = 12 \times p - 12 \times 4}[/tex]

Factor out 12 from the expression on the right-hand side

[tex]\mathbf{12p + 48 = 12 \times (p - 4)}[/tex]

Remove the product sign

[tex]\mathbf{12p + 48 = 12 (p - 4)}[/tex]

Hence, the equivalent expression is 12(p - 4)

The required solution of the given numeral are,
(A) 10⁴ bottles contain 4500 ounces of eye drops. Opion A is correct.
(B) Decimal point moves 4 places to the right. Option D is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
(a)
A bottle of eye drops has 0.45 fluid ounces of liquid.
Now, 10⁴ bottles of eye drops have,
= 10⁴ × 0.45 = 4500 ounces of eye drops.

(b)
When 10⁴ multiplied by 0.45, the decimal located former of 4 will shift itself after 4 digits right so the answer will be 4500.

Answer:

1. 10

4. [tex]3\sqrt{14}[/tex] or 11.22497216

Step-by-step explanation:

1.  [tex]a^{2}+b^{2} =c^{2}\\\\a^{2} = 8^{2} = 64\\b^{2} = 6^{2} = 36\\c^{2} = a^{2} + b^{2} = 64 + 36 = 100\\c = \sqrt{100} = 10[/tex]

2. [tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 24^{2} = 576\\c^{2} = 26^{2} = 676\\b^{2} = c^{2} - a^{2} = 676 - 576 = 100\\b = \sqrt{100} = 10[/tex]

Answer:

458,000

Step-by-step explanation:

Answer:

Step-by-step explanation:

All we need to know here is place value. Here is an example.

458,329

4 = hundred thousandths

5 = ten thousandths

8 = thousandths

3 = hundredths

2 = tenths

9 = ones

The thousands is 8,329. Rounded to the nearest thousand would be 8,000. Five hundred is the lowest it could be to round to 9,000.

458,329 rounded to the nearest thousand would be 458,000.

Answer:

f(x) = 86(1.01)^7x; They grow at approximately the rate of 1% per day.

Step-by-step explanation

86 is the number of weeds at the starting point of the question.

8/7% each day,   7 being the total number of days in the week, the weekly growth 8%:  1 day is 8/7% growth or 1.14% rounded up to 1%

In the original equation the 8% growth was represented by 1.08

Substituting the weekly rate of 8% with the daily rate of 1%, or 1.08 with 1.01 the new function is:

f(x) = 86(1.01)^7x

Answer: The newspaper has 2500 readers.

Step-by-step explanation:

Given: The local newspaper has letters to the editor from 50 people.

This is the 2% of all newspaper readers.

Let x be the number of all newspaper readers.

Then. 2% of x= 50

[tex]\Rightarrow\ 0.02x=50\ \ [\text{To remove }\% \text{we divide number by 100}]\\\\\Rightarrow\ x=\dfrac{50}{0.02}=\dfrac{5000}{2}=2500\\\\\Rightarrow x=2500[/tex]

Hence, the newspaper has 2500 readers.

Answer:

x-intercept is 8

y-intercept is 4

Step-by-step explanation:

3x + 6y = 24 ( subtract 3x on both sides)

6y = -3x + 24 (divide by 6 on both sides)

y = -3/6x + 4 or

y = -1/2x + 4

The y-intercept is 4

To find the x-intercept set y as 0

0 = -1/2x + 4 (we have to get -4)

-1/2*8 = -4

0 = -4 + 4

0 = 0

x-intercept is 8
