For #3, you just have to plug in the numbers for x.
It tells you what to substitute for x in the question. (x = 0, 1, 2, 3, 4, 5, and 6)

For example, let's substitute 0 for x.
6x - x² (the 2 means square the number, or multiply it by itself)
6(0) - (0)²
0 - 0
= 0.

You'll do that to all the numbers (1-6) and fill out the table.

For #4, you have to solve using the distributive property to find out if the equations on both sides are equal.

I'll do the first one for you.

6a - 8 = 2 (3a - 5)
6a - 8 = 6a - 10
They're not equal.

Find the following ratios. Write each answer as a fraction and as a decimal rounded to four decimal places.
Alona [7]

Answer:

y = 56.6208

Step-by-step explanation:

Given

The attached triangle

Required

Find y

To find y, we make use of the relationship between sides lengths 44 & y and angle 39

The relationship is:

cos(39) = \frac{44}{y}

i.e.

cos(\theta) = \frac{Adjacent}{Hypotenuse}

Make y the subject

y = \frac{44}{cos(39)}

y = \frac{44}{0.7771}

y = 56.6208 -- approximated

A taxicab starts at (1, -2) on the grid. It goes 3 blocks east and 1 block south to pick up a passenger. Then it goes 6 blocks w

(x,y)
east is an increase in x
west is a decrease in x
north is an increase in y
south is a decrease in y

so
3 east (x+3)
1 block south (y-1)
6 blocks west (x-6)
5 blocks north (y+5)

so in total, x+3-6 and y-1+5
basically x-3 and y+4
minus 3 from  and add 4 to y
(1,-2)
(1-3,-2+4)
(-2,2) is the dropoff point

zloy xaker [14]

Answer:

1. z = 5,  2. w = 9

Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

I hope this helps :)

julsineya [31]

Answer:

The value of 2008 is 112% of the Value of 2007.

But we need 100% of the year of 2007.

So 350000/112=3125=>1%

3125*100=312500=>100%

The answer is $312500

1.A: 86 is equal to (86=) 45 % (which is 0.45) of a number n so 86=0.45n

2. C 4 is npercent of 26, so 4=n*26 where n is a number in percent, with the percent sign!
