Question:

Here are five sums. Use the distributive property to write each sum as a product with two factors.

[tex](a)\ 2a + 7a[/tex]      [tex](b)\ 5z - 10[/tex]    [tex](c)\ c - c^2[/tex]      [tex](d)\ r + r+ r+ r[/tex]    [tex](e)\ 2x - \frac{1}{2}[/tex]

Answer:

[tex](a)\ 2a + 7a = 9a[/tex]

[tex](b)\ 5z - 10 = 5(z - 2)[/tex]

[tex](c)\ c - c^2 = c(1 - c)[/tex]

[tex](d)\ r + r + r + r = 4r[/tex]

[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Step-by-step explanation:

Required

Apply distributive property

[tex](a)\ 2a + 7a[/tex]      

Apply distributive property [Factor out a]

[tex]2a + 7a = a(2 + 7)[/tex]

[tex]2a + 7a = a(9)[/tex]

Open bracket

[tex]2a + 7a = a*9[/tex]

[tex]2a + 7a = 9a[/tex]

[tex](b)\ 5z - 10[/tex]    

Express 10 as 5 * 2

[tex]5z - 10 = 5z - 5*2[/tex]

Apply distributive property [Factor out 5]

[tex]5z - 10 = 5(z - 2)[/tex]

[tex](c)\ c - c^2[/tex]      

Express c as c * c

[tex]c - c^2 = c - c * c[/tex]

Apply distributive property [Factor out c]

[tex]c - c^2 = c(1 - c)[/tex]

[tex](d)\ r + r+ r+ r[/tex]    

Express r as r * 1

[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]

Apply distributive property [Factor out 1]

[tex]r + r + r + r = r(1+1+1+1)[/tex]

[tex]r + r + r + r = r * 4[/tex]

[tex]r + r + r + r = 4r[/tex]

[tex](e)\ 2x - \frac{1}{2}[/tex]

Express 2x as 4x/2

[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]

Apply distributive property [Factor out 1/2]

[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Step-by-step explanation:

The kitten weighs_____pounds every week                    -0.6 pounds

Weight of the kitten at current time                                    -7 pounds

Weeks it will take for the kitten to reach 10 pounds         -0.6+7=7.6

                                                       now round it off and you will get 7

                            ∴the kitten will take 7 more weeks for getting to 10 pounds            

The kitten will be at least 10 pounds after 5 weeks. Let's set up an equation to solve for the number of weeks needed for the kitten to reach at least 10 pounds.

Let "w" represent the number of weeks.

The weight of the kitten after "w" weeks can be calculated as:

Weight = Initial weight + (Weight gained per week * Number of weeks)

Weight = 7 + (0.6 * w)

We want to find the number of weeks when the weight is at least 10 pounds:Weight ≥ 10

Substituting the equation for weight:

7 + (0.6 * w) ≥ 10

Subtracting 7 from both sides:

0.6 * w ≥ 3

Dividing both sides by 0.6:

w ≥ 3 / 0.6

w ≥ 5

Therefore, the kitten will be at least 10 pounds after 5 weeks.

Step-by-step explanation:

Answer: $400,000

Step-by-step explanation:

Let the salesperson's total amount of sales, in dollars, for this year be represented by x.

Therefore, 60% of x = $240,000

60/100 × x = $240,000.

0.6 × x = $240,000..

x = $240000 / 0.6

x = $400,000

Therefore, the salesperson's total amount of sales, for this year is $400,000.

Answer:

Step-by-step explanation:

Find the change between the first two sets:

12-9 = 3

14.4 - 10.8 = 3.6

3.6/3 = 1.2

Now find the change between the last two sets:

12 - -3 = 15

14.4 - 3.6 = 10.8

10.8/15 = 0.72

1.2 does not equal 0.72 so the answer is No

Answer:

D.  y = -2/3 x + 4/3

Step-by-step explanation:

When you have a perpendicular line, everything except the y-intercept becomes opposite. So 3/2x + 6 will become -2/3x.

To find the slope, you have to plug the coordinates into the equation so far which is y = -2/3x + b

y = -2/3x + b

2 = -2/3(-1) + b

2 = 2/3 + b

4/3 = b

So the equation is y = -2/3 x + 4/3.

Answer:

a) Only the first one is an identity.

Step-by-step explanation:

1). 8 cos O tan O csc O = 8   simplifies to:

cos O tan O csc O = 1

cos O * (sin O / cos O) * (1 /sin O)

=  cos O sin O / cos O sin O

= 1

So it is identity.

2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O

= 13 sec^2 O - tan^2 O / cos^2 O

Now  sec^2 O = 1 + tan^2 O, so we have:

(13( 1 + tan^2 O) - tan^2 O) / cos^2 O

= (12 tan^2 O + 13) / cos^2 O

This is not always = 2 so its not an identity.

Answer: C

Step-by-step explanation:

[tex]A = \frac{1}{2} (b+c)h\\[/tex] -> This is the original equation

[tex]\frac{A}{h} = \frac{1}{2} (b+c)\\[/tex] -> Divide by h on both sides

[tex]2\frac{A}{h} = b+c\\[/tex] -> Multiply both sides by 2

[tex]2\frac{A}{h}-b = c\\[/tex] -> subtract b from both sides

Answer: -36

Step-by-step explanation:

13, 6, -1

to get from 13 to 6 and 6 to -1, you would subtract by 7 so keep subtracting by 7 until you get 8 different terms

13, 6, -1, -8, -15, -22, -29, -36

the eighth term would be -36
