find an equation for the line that passes through the points (5, -4) and (1, -2)

Answers

Answer 1

Answer:

y=-3/2x-.5

Step-by-step explanation:

(5,-4) and (1,-2)

Step 1: find slope:

-4-2/5-1=-6/4=-3/2

y=mx+b

y=-3/2x+b

2.: Plug in point

(1,-2)

-2=-3/2*1+b

-2=-3/2+b

Alex has five cups of strawberries. He wants to use / cups of strawberries for a fruit salad and / cups

Answers

Answer:

Since Alex only has 5 cups of strawberries, he does not have enough to make both recipes.  

Step-by-step explanation:

1 3/4 cups of strawberries + 3 1/2 cups of strawberries= 5 1/4 cups of strawberries. Alex needs more strawberries.

Answer:

No.

Step-by-step explanation:

To solve the Yes/No question,

First, write the equation:

5 = \(1\frac{3}{4}\) + \(3\frac{1}{2}\)

Then convert the mixed fraction to improper ones:

5 = \(\frac{7}{4}\) + \(\frac{7}{2}\)

Then find the LCM of the denominators 4 & 2 ( = 4 ) and solve:

5 = \(\frac{7}{4}\) + \(\frac{14}{4}\)

5 = \(\frac{7+14}{4}\)

5 = \(\frac{21}{4}\)

5 = 5.25

5 < 5.25

So because 5.25 is greater than 5, he doesn't have enough strawberries to make the recipes.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Answer:

Option 3 (79−3x=12x+19)

Step-by-step explanation:

When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.

Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Given that, the equations that have {4} as its solution set.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) Solution of an equation 5 + 2x = 3x + 3 is

3x-2x=5-3

⇒x=2

2) Solution of an equation 7−x=12x is

7−x=12x

⇒12x+x=7

⇒13x=7

⇒x=7/13

3) Solution of an equation 79−3x=12x+19 is

12x+3x=79-19

⇒15x=60

⇒x=4

4) Solution of an equation x²+3=10x−21 is

x²+3=10x−21

⇒ x²-10x+24=0

⇒ x²-6x-4x+24=0

⇒ x(x-6)-4(x-6)=0

⇒ (x-6)(x-4)=0

⇒ x=6 or 4

Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Thank you!♡

Cube Roots of Negative Numbers.Thank you!

Answers

Answer:The cube root of a negative number is a complex number because there is no real number that, when cubed, gives a negative result.

To find the cube root of -1, we can express it in exponential form as -1 = 1 * e^(iπ), where i is the imaginary unit and π is pi.

The cube root of -1 can be calculated by applying De Moivre's theorem, which states that (r * e^(iθ))^(1/n) = r^(1/n) * e^(iθ/n), where r is the magnitude and θ is the argument of the complex number.

For n = 3, the cube root of -1 becomes:

(-1)^(1/3) = (1 * e^(iπ))^(1/3) = 1^(1/3) * e^(iπ/3) = e^(iπ/3).

Therefore, the cube root of -1 is e^(iπ/3), which can also be expressed as cos(π/3) + i * sin(π/3).

In trigonometric form, the cube root of -1 is (√3/2) + i * (1/2).
