Box method for (x-5)(6x+12)

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1

Please correct me if I'm wrong.

Answer:

f(12) = 11

Step-by-step explanation:

Step 1: Define

f(x) = 2/3x + 3

f(12) is x = 12

Step 2: Substitute and Evaluate

f(12) = 2/3(12) + 3

f(12) = 8 + 3

f(12) = 11

Answer:

-19

Step-by-step explanation:

Answer:

y = 53

Step-by-step explanation:

To get the answer, first put 19 in place of the x, and then times that iwth two, getting 38, you add that to 15. The answer is 53.

Answer:The Value of the coin after 19 years is $53.

Step-by-step explanation:If x=age, then simply substitute the x in “2x+15” for 19.After you do that you should get y=2(19)+15.Do the math to get y=38+15. Y=53.

Answer:

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

x = $0.76*10²

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

Answer:

A.3

Step-by-step explanation:

Answer: 55

110 ÷ 2 = 55         110 in half is 55 because 10 in half is 5 and  100 in half is 50 so 55 +5 = 55

110÷2=55

Answer:

C.

Step-by-step explanation:

Answer:

I think its B.

Step-by-step explanation:

Answer:

Step 1: Simplify both sides of the equation.

−7+3(8n−8)=8(7+3n)

−7+(3)(8n)+(3)(−8)=(8)(7)+(8)(3n)(Distribute)

−7+24n+−24=56+24n

(24n)+(−7+−24)=24n+56(Combine Like Terms)

24n+−31=24n+56

24n−31=24n+56

Step 2: Subtract 24n from both sides.

24n−31−24n=24n+56−24n

−31=56

Step 3: Add 31 to both sides.

−31+31=56+31

0=87

Answer:

The domain is {-6, 3, 4, 6, 10}

The range is {-13, -9, 2, 14, 19}

Step-by-step explanation:

Any set of ordered pairs has a domain and a range

The domain is the values of x-coordinates of all ordered pairs

The range is the values of y-coordinates of all ordered pairs

∵ The set is {(-6, 14), (10, 19), (4, -9), (3, 2), (6, -13)}

∵ x-coordinates of all points are -6, 10, 4, 3, 6

→ These values are the domain of the set

∴ The domain is {-6, 3, 4, 6, 10}

∵ y-coordinates of all points are 14, 19, -9, 2, -13

→ These values are the range of the set

∴ The range is {-13, -9, 2, 14, 19}

Answer:

B) It is a product, so it is released by the plant.

Step-by-step explanation:

- Plants release oxygen for humans and humans give carbon dioxide to plants.

- The role of oxygen in photosynthesis is a waste product.

Answer: The oxygen gas is a product, so it is released by the plant.

Explanation:

Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.

The chemical equation representing this reaction follows:

In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.

Hence, the oxygen gas is a product, so it is released by the plan.

Answer:

Step-by-step explanation:

isosceles triangle

solve for x:

JK = KL

8x = 13x - 15

15 = 13x - 8x

15 = 5x

x = 3

solve for y:

180 = 76 + 2(5y - 3)

180 - 76 = 10y - 6

10y = 110

y = 11

Answer:

Step-by-step explanation:

Given that, r varies inversely with u. r=k÷u, k being the constant.

Therefore, k=8×5, ( after making k the subject of your formula).

This implies that k=40.

Now, according to the formula r=k÷u,

r=40÷55

Therefore, r=0.72
