Solve the system of equations algebraically.

*If necessary, write your answers as fractions in simplest form.

y = x + 2
y = -3x

Answers

Answer 1

Answer:

Step-by-step explanation:

y = x + 2  -------------(i)

y = -3x ----------------(ii)

substitute y = -3x i equation (i)

-3x = x + 2

-3x -x = 2

-4x = 2

x = 2/-4

x = -1/2

Substitute x = -1/2 in (ii)

y = -3 * -1/2

y = 3/2

Find m< HIF
Show your work

Answers

Answer: m/HIF =110•

Step-by-step explanation:

The measure of angle HIF is 13.89°.

To find the measure of angle HIF (m∠ HIF), we need to use the fact that the sum of angles in a triangle is 180 degrees.

Let's denote the measure of angle JIF as y.

According to the given incorrect solution, we have:

m∠ JIF + m∠ IFJ + 90 = 180

But the sum of angles JIF and IFJ isn't necessarily 90 degrees unless we know more about the triangle or have additional information.

However, since we know that the sum of angles in triangle JIF is 180 degrees, we can use this to find the measure of angle HIF.

We have:

m∠ JIF + m∠ IFJ + m∠ HIF = 180

We know that m∠ JIF = 7x + 3 and m∠ IFJ = 2x + 6. Plugging these values in, we get:

(7x + 3) + (2x + 6) + 46 = 180

Combine like terms:

7x + 3 + 2x + 6 + 46 = 180

9x + 55 = 180

Subtract 55 from both sides:

9x = 125

Divide both sides by 9:

x = 125 / 9

Now, we can find the measure of angle HIF by substituting the value of x into the expression for m∠ HIF:

m∠HIF = 13.89°

How is a debit card similar to an ATM card?

Answers

C. Both can be used to withdraw money from ATMs.

A debit card and an ATM card share certain similarities, but they also have distinct differences. Let's focus on the similarities both can be used to withdraw money from ATMs (option c).

The primary similarity between a debit card and an ATM card is that they can both be utilized to withdraw cash from Automated Teller Machines (ATMs). When using either card at an ATM, the cardholder can access their bank account and withdraw funds, check balances, and perform other account-related transactions.

However, it is crucial to note the differences between these two types of cards. A debit card is linked to a checking or savings account and allows the user to make purchases in stores, online, or through other payment methods. It deducts the amount spent directly from the linked bank account. On the other hand, an ATM card is typically used only for ATM transactions and lacks the functionality to make purchases like a debit card.

In summary, both a debit card and an ATM card can be used to withdraw money from ATMs, but a debit card offers additional features and can be used for various transactions, including online and in-store purchases.

What is the magnitude of the resultant vector a and b shown below?

Answers

Answer: SECOND OPTION.

Step-by-step explanation:

It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.

 For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:

[tex]c=\sqrt{a^2+b^2}[/tex]

Where "c" is the magnitude of the resultant vector asked in the exercise.

You need to analyze the graph given in the exercise.

You can identify that:

[tex]a=4\\\\b=3[/tex]

Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:

[tex]c=\sqrt{4^2+3^2}[/tex]

Finally, evaluating, you get that "c" is:

[tex]c=\sqrt{16+9}\\\\c=5[/tex]

Final answer:

The magnitude of the resultant vector a and b is 5.

Explanation:

The magnitude of the resultant vector a and b can be found using the Pythagorean theorem.

The Pythagorean theorem states that the magnitude of the resultant vector is equal to the square root of the sum of the squares of its individual vector components.

Let's assume vector a has a magnitude of 3 and vector b has a magnitude of 4. First, we square the magnitude of each vector: a^2 = 3^2 = 9 and b^2 = 4^2 = 16.

Then, we sum the squared magnitudes: a^2 + b^2 = 9 + 16 = 25. Finally, we take the square root of the sum: magnitude of the resultant vector = sqrt(25) = 5. So, the magnitude of the resultant vector a and b is 5.

A sphere with radius 0.5 inches.
A sphere with radius 0.6 inches.
A sphere with radius 0.7 inches.

Answers

Answer:

Step-by-step explanation:

Answer in the photo

A sphere that has a volume 0.288π inches cube has a radius of 0.6 inches

Volume of a sphere

The volume of a sphere is described as follows:

volume of sphere  = 4 / 3 πr³

where

r = radius of the sphere

Therefore,

volume = 0.288π inches cube

Hence, the radius can be calculated as follows;

0.288π  =  4 / 3 πr³

divide both side by π

0.288 = 4 / 3r³

cross multiply

0.288 × 3 = 4r³

0.864 = 4r³

divide both sides by 4

r³ = 0.864 / 4

r = ∛0.216

r  = 0.6 inches

Therefore, a sphere that has a volume 0.288π inches cube has a radius of 0.6 inches

Answer:

y = 3[tex]\sqrt{7}[/tex]

Step-by-step explanation:

The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{y}{9}[/tex] = [tex]\frac{7}{y}[/tex] ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = [tex]\sqrt{63}[/tex] = [tex]\sqrt{9(7)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{7}[/tex] = 3[tex]\sqrt{7}[/tex]

You can use the pythagorian theorem here:
The corner on the top side is 90 degrees too. So that means (9+7)^2 = A^2 + B^2. The two triangles against each other are the same, but bigger. That means that the left side is 9/16 out of the whole and the right side is 7/16 out of the whole So back to the pythagorean theorem (9+7)^2 = 256. Multiply that number by one of the two numbers before. I will take 9/16, the left side. 256x9/16 = 144. Take the square root of that, 12, and then you have the length of that side. Then use pythagorean theorem again. C^2 = 9^2 + 12^2
C^2 = 225.
C= 15

Can someone help? Identify the system of linear equations from the tables of values given below.​

Answers

Answer:

C

Step-by-step explanation:

The equation y = x + 2 does not match these data points either. So, option D is not the correct answer.

Let's analyze each option:

A. y = -2x - 2

This equation represents a linear relationship with a slope of -2 and a y-intercept of -2. It does not seem to match the given data points.

B. -2

This is not an equation, so it cannot be a solution.

C. y = 8 + 2x, y = x + 1

The first equation, y = 8 + 2x, represents a linear relationship with a slope of 2 and a y-intercept of 8.

The second equation, y = x + 1, also represents a linear relationship with a slope of 1 and a y-intercept of 1.

Now, let's check if these equations match the given data points:

Data points: (X, Y) = (0, 0), (0, -4), (0, -2), (0, -4), (0, 0), (0, -1), (0, 2), (0, 6), (0, -6), (0, -1), (0, 2)

None of the equations in option C match these data points. So, option C is not the correct answer.

. y = x + 2

This equation represents a linear relationship with a slope of 1 and a y-intercept of 2.

Now, let's check if this equation matches the given data points:

Data points: (X, Y) = (0, 0), (0, -4), (0, -2), (0, -4), (0, 0), (0, -1), (0, 2), (0, 6), (0, -6), (0, -1), (0, 2)

Choose all answers that apply: A) 8/-3 B) - 8/-3 C)
None of the above

Answers

Answer:

A

Step-by-step explanation:

To determine which expressions are equivalent to -(8 divided by 3), let's perform the calculation first. Therefore the correct option is A

The division of 8 by 3 can be written as 8/3, which equals to 2.6666 (rounded to four decimal places). When we apply the negative sign to this result, we get -(2.6666) or -2.6666. Now, let's consider the given answer choices: A) 8 divided by -3: This expression corresponds to 8/(-3), which equals to -2.6666. Since this matches the calculated value of -2.6666, option A is equivalent.

B) -8 divided by -3: This expression translates to [tex](-8)/(-3),[/tex] which simplifies to 2.6666. As this value does not match the calculated result of -2.6666, option B is not equivalent. Therefore, by comparing the results, we can conclude that option A (8 / -3) is equivalent to -(8 / 3), while option B (-8 / -3) is not. To summarize, the expression -(8 /3) can be represented as 8 by -3 (option A). Option B (-8 / -3) is not equivalent.

Thus, the correct answer is A) 8 /-3.
