ANSWER:
13 ÷4
STEP-BY-STEP EXPLANATION:
In this case we have a mixed number. To convert a mixed number to a fractional number (quotient), we must multiply the whole part by the denominator and that add it to the numbered one, and that would be the new numerator, while the denominator is converted, just like this:
\(\begin{gathered} 3\frac{1}{4}=\frac{3\cdot4+1}{4}=\frac{12+1}{4}=\frac{13}{4} \\ 13\div4 \end{gathered}\)When you’ve finished solving an equation, it’s easy to check your work. Simply plug your answer for the variable into the original equation. Take, for example, the equation 4x + 9 = 45. After isolating the variable, you’ve come up with x = 9. To check your work, replace the x with 9: 4(9) + 9 = 45. Following the order of operations, multiply 4 by 9 first to get 36 + 9 = 45. Adding 36 plus 9 does equal 45, so you know you’ve found the right value for x. Which of these equations is correct when x = -2? A x + 8 = 5 B 3x - 1 = -10 C 2x - 7 = -11 D -95x = -190 BACK
The required correct equations are 2x - 7 = -11 and -95x = -190. Options C and D are correct.
What is the equation?
The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
As of the given example in the question,
Putting x = -2 to in every op[tion,
A,
X + 8 = 5
-2 + 8 = 5
6 ≠ 5
Similarly,
B. -7 ≠ -10
C. -11 = -11
D. -190 = -190
Thus, the required correct equations are 2x - 7 = -11 and -95x = -190. Options C and D are correct.

I need help for this math question!
Answer:
D
Step-by-step explanation:
Assuming that the expression is referring to sin²(2πft) and not sin²(2)πft, we can solve as follows:
One trigonometric identity states that sin²x+cos²x = 1. We want to express this in terms of cos²x, so we need to solve for sin²x. Subtracting cos²x from both sides, we get 1-cos²x = sin²x. Plugging (2πft) for x, we get
1-cos²(2πft) = sin²(2πft)
We can plug that into our equation to get
P = I₀²R(1-cos²(2πft)), or D
Amy and three friends are renting a house near the campas for $2400 per month. She plays 1/4 of the rent. What is her monthly rent?
Answer:
Amy has to pay $600 every month for rent.
Step-by-step explanation:
To take 1/4 of a number is to multiply 1/4 and said number.
So you can do 0.25*number
or number/4.
For this problem, the number is 2400 because Amy is going to pay 1/4 of 2400 for rent.
\(rent = 2400/4\\rent = 600\)

The Celsius scale for measuring temperatures is given by 9C = 5F-160, where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit.
Which system of equations would give the temperature where the degrees Celsius and degrees Fahrenheit are equal?
The correct option of system of equations that can be used to find the temperature at which the degrees Celsius and the degrees Fahrenheit would be equivalent is the option;
5·F - 9·C = 160
F - C = 0
What is a system of equation?A system of equation, is a set of equation that have common variables.
The equation for conversion of the temperature in degrees Celsius to the temperature in degrees Fahrenheit is; 9·C = 5·F - 160
When the temperature in degrees Celsius is equivalent to the temperature in degrees Fahrenheit, we get;
F = C
Therefore;
F - C = 0
Similarly, from the specified equation, we get;
9·C = 5·F - 160
5·F - 9·C = 160
The system of equation that would give the temperature where the degrees Celsius and degrees Fahrenheit are equivalent is therefore;
5·F - 9·C = 160
F - C = 0

Which of the following equations represents a linear function?
2x − 4 = 6
x = −2
y equals one half times x squared
y equals two thirds times x plus 4
Answer:
y equals 2/3 x plus 4 is correct.
The equation y= 1/3x + 4 represents a linear function.
What is Linear Equation?A linear function is a function that can be represented by a straight line. The equation of a linear function is typically in the form y = mx + b, where m represents the slope and b represents the y-intercept.
1. 2x − 4 = 6 is a linear equation, but it is not a function because it does not isolate y.
2. x = −2" represents a vertical line with a slope of infinity, but it does not have the form y = mx + b.
3. y = 1/2x² represents a quadratic function because it contains x raised to the power of 2.
4. y= 1/3x + 4 represents a linear function.
Therefore, the equation y= 1/3x + 4 represents a linear function.

The speed of the plane is equal to 120 mph.
What is speed?In Mathematics and Geometry, speed is the distance covered by a physical object per unit of time. This ultimately implies that, speed can be measured by using miles per hour (mph).
Mathematically, the speed of any a physical object can be calculated by using this formula;
Speed = distance/time
Time = distance/speed
Let the variable s represent the speed of the plane in miles per hour. Therefore, an equation that models the situation can be written as follows;
240/s = 80/s - 80
80s = 240s - 19200
19200 = 160s
s = 19200/160

Plotting points that conform to the function's rule in a cartesian coordinate system results in the graph of the function. An input-output pair for the function is represented by each point on the graph. The point's x-coordinate represents the input value, while its y-coordinate represents the output value.

what is the y intercept of the line that passes through the point 3, 4 and has a slope of 3
(0, -5)
Step-by-step explanation:
Since we are given the slope and a point on the line, we can use these to write the point-slope form of the equation of the line, which looks this this:
\(y - y_1 = m(x - x_1)\)
where \((x_1, y_1)\) is the point on the line and m is the slope. So the equation has the form
\(y - 4 = 3(x - 3)\)
To find the y-intercept, set x = 0 to get
\(y - 4 = 3(0 - 3) \Rightarrow y - 4 = -9\)
Solving for y, we get
\(y = -5\)
Therefore, the coordinates of the y-intercept is (0, -5).
