Which is the correct way to model the equation 5 x + 6 = 4 x + (negative 3) using algebra tiles? 5 positive x-tiles and 6 positive unit tiles on the left side; 4 positive x-tiles and 3 negative unit tiles on the right side 6 positive x-tiles and 5 positive unit tiles on the left side; 3 negative x-tiles and 4 positive unit tiles on the right side 5 positive x-tiles and 6 negative unit tiles on the left side; 4 positive x-tiles and 3 negative unit tiles on the right side 5 positive x-tiles and 6 positive unit tiles on the left side; 4 positive x-tiles and 3 positive unit tiles on the right side

Answer:

20 sides

Step-by-step explanation:

use the formula

360°/exterior angle

360°÷18°=20 sides

f(-2) = 2(-2)+3

f(-2) = -4+3

f(-2) = -1

g(4) = (4) - 7

g(4) = -3

f(-2) + g(4) is -1 + (-3) which is -4

Answer:

[ 0, 2 ] is the interval for the graphed function that contains the local maximum. Hence, the answer is [ 0, 2 ] is the answer.

Step-by-step explanation:

-18-(-16) is -2

Answer:

y = (2/3)x

Step-by-step explanation:

Note that (0, 0) and (3, 2) are both points on this line.  The change in y as we go from  (0, 0) to (3, 2) is +2 and the change in x is +3.  

The slope of this line is this m = rise/run = 2/3

and so the desired equation is y = (2/3)x

Answer:

B) Slope = 2.5, y-intercept = –5

Step-by-step explanation:

Given the following points on the grid, (-1.5, -8.75) and (3.5, 3.75), the slope can be calculated as follows using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (-1.5, -8.75) = (x_1, y_1) [/tex]

[tex] (3.5, 3.75) = (x_2, y_2) [/tex]

[tex] m = \frac{3.75 -(-8.75)}{3.5 -(-1.5)} [/tex]

[tex] m = \frac{3.75 + 8.75}{3.5 + 1.5} [/tex]

[tex] m = \frac{12.5}{5} [/tex]

[tex] m = 2.5 [/tex]

Slope = 2.5.

The y-intercept is the point at which the line intercepts the y-axis. On the graph, the line intercepts the y-axis at y = -5. Therefore, the y-intercept = -5.

Answer:

-35, -33, -31

Step-by-step explanation:

Let the 3 consecutive odd integers be x+1,x+3,x+5

Given, x+1+x+3+x+5=-99

3x+9=-99

3x=-108

x=-36

The 3 odd integers are x+1 = -35, x+3=-33, x+5=-31

Answer:

alternate interior angles and x = -6

Step-by-step explanation:

they should equal each other, so 75 = x+ 81

75-81 = -6

Answer:

see below

Step-by-step explanation:

sin x = cos x

opp/ hyp = adj /hyp

Multiply each side by the hypotenuse

opp = adj

The opposite side must equal the adjacent

Since this is a right triangle

opp ^2 + adj ^2 = hypotenuse^2

opp ^2 + opp ^2 = hypotenuse^2

2 opp ^2 = hypotenuse^2

Take the square root of each side

sqrt(2 opp ^2) =sqrt( hypotenuse^2)

sqrt(2) opp = hyp

We know sin X = opp / hyp

sin x =  opp / (sqrt(2) / hyp)

sin x = 1 / sqrt(2)

sin x = sqrt(2) /2

Taking the inverse sin of each side

x = sin ^-1 ( sqrt(2) /2)

Answer:

35,000 feet

Step-by-step explanation:

So t is the atmospheric temperature

g is the ground temperature

First sub in the values that you know

t = -65.5 and g = 57

-65.5 = -0.0035a + 57

Rearrange: to make 'a' on its own

-65.5 - 57 = -0.0035a

-122.5/-0.0035 = a

Use a calculator

a = 35,000 ft

Answer:

30 of the 15 cent stamps and 50 of the 25 cent stamps

Step-by-step explanation:

Create a system of equations, where x is the number of 15 cent stamps and y is the number of 25 cent stamps:

x + y = 80

0.15x + 0.25y = 17

Solve by substitution by rearranging the first equation:

x + y = 80

x = 80 - y

Substitute 80 - y as x into the second equation:

0.15x + 0.25y = 17

0.15(80 - y) + 0.25y = 17

12 - 0.15y + 0.25y = 17

12 + 0.1y = 17

Solve for y:

0.1y = 5

y = 50

Plug in 50 as y into the first equation, and solve for x:

x + y = 80

x + 50 = 80

x = 30

So, you bought 30 of the 15 cent stamps and 50 of the 25 cent stamps

answer: ten 15¢ stamps and forty 20¢ stamps.

Answer:

$130

Step-by-step explanation:

Given:

I = (S − P) / P

where,

P = purchase price and

S = sale price.

What was the purchase price of the stock?

I = 30%

S = $91

I = (S − P)/P

30% = (91 - P) / P

0.3 = (91 - P) / P

Cross product

0.3P = 91 - P

0.3P + P = 91

0.7P = 91

P = 91 / 0.7

P = $130

Answer:

wheres the other page??

Step-by-step explanation:

Answer:

the question is incomplete, so I looked for similar questions:

There are 3 sandwiches, 4 drinks, and 2 desserts to choose from.

the answer = 3 x 4 x 2 = 24 possible combinations

Explanation:

for every sandwich that we choose, we have 4 options of drinks and 2 options of desserts = 1 x 4 x 2 = 8 different options per type of sandwich

since there are 3 types of sandwiches, the total options for lunch specials = 8 x 3 = 24

If the numbers are different, all we need to do is multiply them. E.g. if instead of 3 sandwiches there were 5 and 3 desserts instead of 2, the total combinations = 5 x 4 x 3 = 60.

Answer:

29

Step-by-step explanation:

sum of angles in a triangle=180°

180-(67+84)=29°

Answer:

Angle 1 and Angle 5

Step-by-step explanation:

Since we know that a straight angle is 180 degrees this means that angle 2+5+1 is 1/2 of a full angle. We also know that angle 2 is 90 degrees or a right angle, we can subtract 180 - 90 which equals 90 degrees. Since two complementary angles add up to 90 degrees. This 100% assures us that angle 1 + angle 5 are the two complementary angles.

Hope this Helps!!! :)

Answer:

The amount invested on 5.6% interest = $80488

The amount invested on 9.7% interest = $69512

Step-by-step explanation:

Given that total amount of investment = $150,000

Let the amount invested on 5.6% interest = $[tex]x[/tex]

Now, amount invested on 9.7% interest = $(150000-[tex]x[/tex])

Total interest to be earned = 7.5%

Formula to be used:

[tex]Simple\ Interest = \dfrac{P\times r\times t}{100}[/tex]

Where, [tex]P[/tex] is the amount invested

[tex]r[/tex] is the rate of interest

[tex]t[/tex] is the time for which amount is invested.

As per question statement:

[tex]\dfrac{x\times 5.6}{100}+\dfrac{(150000-x)\times 9.7}{100}=\dfrac{150000\times 7.5}{100}\\\Rightarrow 5.6x-9.7x=150000(7.5-9.7)\\\Rightarrow 4.1x=150000\times 2.2\\\Rightarrow x = \dfrac{330000}{4.1}\\\Rightarrow x \approx \bold{\$80488}[/tex]

The amount invested on 5.6% interest = $80488

The amount invested on 9.7% interest = $150000 - $80488 = $69512

Answer:

x=4

Step-by-step explanation:

–3(3x –2) = –30

Divide each side by -3

–3(3x –2)/-3 = –30/-3

3x –2 = 10

Add 2 to each side

3x –2+2 = 10+2

3x = 12

Divide each side by 3

3x/3 = 12/3

x = 4

Answer:

X = 4

Step-by-step explanation:

1: Distribute

-3 (3x - 2) = -30 (Multiply 3x and -2 by -3)

-9x + 6 = -30

2: Combine Like Terms

-9x + 6 = -30 (Subtract 6 from -30)

-9x = -36

3: Divide

-9x = -36 (Divide -36 by -9 to get x by itself)

x = -36 / -9

4: Solve

x = -36 / -9

X = 4
