Answer: True, False, False, False, False

Step-by-step explanation:

a) 5x - 7(x - 1)

5x - 7x + 7

-2x + 7 ⇒ a = -2, b = 7 One Solution

b) 3(x - 5) - 7

3x - 15 - 7

3x - 22 ⇒ a = 3, b = -22 One Solution

c) 2 - 7x + 3 + 4x

4x - 7x + 3 + 2

-3x + 5 ⇒ a = -3, b = 5 One Solution

d) -3(x - 3) - 1

-3x + 9 - 1

-3x + 8 ⇒ a = -3, b = 8 One Solution

e) -5x + 2 + 2x + 4

-5x + 2x + 2 + 4

-3x + 6 ⇒ a = -3, b = 6 One Solution

Explain how to draw a circle with a circumference of 3.14^2 inches. then draw the circle.

ch4aika [34]

This is what I would do.

The general formula for the circumference of a circle is

$2\pi \: r$

where r is the length of the radius of the circle. Simply use the formula to find r so that you can draw the circle:

$2\pi \: r = 3.14 ^{2} inches \\ r = \frac{3.142 ^{2} }{2\pi} = 1.571 \: inches$

Now, draw a circle with a radius of 1.571 inches. This number has been rounded up to 3 significant figure. Hope this helps!

ASHA 777 [7]

Answer:

$135

Step-by-step explanation:

We can answer this by multiplying $150 by (1.00 - 0.10), or by 0.90:

0.90($150) = $135.

Note that 1.00($150) = $150 (full price)

and that 0.10($150) = $15 (discount)

and that (0.90)($150 = $135 (the fastest way to calculate the final (sale) price.

Rewrite as a quotient of two base- 5 logarithms. Write your answer in simplest form. log 9 =

const2013 [10]

$\log(9)=\log_{10}(9)=\dfrac{\log_{5}(9)}{\log_{5}(10)}$

In my opinion, that is the simplest form. However, your teacher may want you to remove powers and factors of 5. In that case, the result is ...

$=\dfrac{\log_{5}(3^{2})}{\log_{5}(5\cdot 2)}=\dfrac{2\log_{5}(3)}{1+\log_{5}(2)}$
