What is the equation of the line written in slope-intercept from?
Answers
Answer:
Step-by-step explanation:
As we move along the graph from x = 2 to x = 3 (a change of 1), y decreases from y = 100 to y = 0 (a change of -100). Thus, the slope of this line is
m = rise / run = -100/1 = -100.
The y-intercept is the point where the graph crosses the y-axis, and is (0, 200).
The equation of this line in slope-intercept form is y = -100x + 200

• Which of these are equivalent to -11/4 ? Choose ALL that apply.
Answers
The options equivalent to the given fraction are: -11 ÷ 4, -11 ÷(- 4), [tex]\frac{-11}{4}[/tex] , [tex]\frac{11}{-4}[/tex]
[tex]-\frac{11}{4}[/tex] is an improper fraction. An improper fraction is a fraction in which the numerator is larger than the denominator. [tex]\frac{-11}{4}[/tex] can also be written as -11 ÷ 4.
In order to determine the answers, take note of the following rules:
When a negative number is divided by a positive number, the result is a negative number. -8 ÷ 2 = -4When a positive number is divided by a negative number, the result is a negative number. 8 ÷ -2 = -4When a negative number is divided by a negative number, the result is a positive number. -8 ÷ -2 = 4Using the above rules, the equivalent options are: -11 ÷ 4, -11 ÷(- 4), [tex]\frac{-11}{4}[/tex] , [tex]\frac{11}{-4}[/tex]
A similar question was answered here: https://brainly.com/question/15382096?referrer=searchResults
The first, second, fourth, and fifth options among all are equivalent to [tex]\frac{-11}{4}[/tex].
These all are forms of division.
The division is an arithmetic operation that involves splitting a quantity or number into equal parts or groups. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to obtain the quotient.
The dividend is the total quantity or number being divided, while the divisor is the number by which the dividend is divided. The result of the division is called the quotient, which represents the number of times the divisor can be subtracted from the dividend to achieve equal parts.
Hence, the first, second, fourth, and fifth options are correct.

Which of the following does not state a principle related to why ground wires are an effective safety device? O A. Electronic devices are protected from power surges by having insulated wires. B. Electricity will travel more easily through metal than through insulators. C. When enough electricity builds up, it could pass through highly resistant materials to get to the Earth. D. Electricity always wants to travel "downhill" toward the Earth.
Answers
A; electronic devices are protected from power surges by having insulated wires.
The option that does not state a principle related to why ground wires are an effective safety device is:
A. Electronic devices are protected from power surges by having insulated wires.
Insulated wires protect electronic equipment against power surges, however, this has nothing to do with the usefulness of ground wires as a safety precaution.
The idea of earth wires is to provide a safe conduit for electrical currents to go into the Earth, avoiding harmful electrical potential from building up.
Thus, options B, C, and D all state principles that are directly related to the effectveness of ground wires as a safety device.
Hence, the correct answer is A.
