Answer: B. Ryder had $6.25. He needs to buy school supplies and ends up owing his mother $2.50
Step-by-step explanation: The number line only has single digits and every other answers have extreme changes while B has the lowest change that fits in the number line.
Answer:
x = 104° because they are alternate interior angles and alternate interior angles are equal
Step-by-step explanation:
Y=0.6x+5 is the slope of a line parallel to the line -3x+5y=-10
5^2 + 3^2 (equals to 34) ; That's the wrong expression
It should look like this : (5+3)^2 (which equals to 64)
Answer:
For 124 chirps per minute the temperature is 68 ºF.
For 68 chirps per minute the temperature is 54 ºF.
Step-by-step explanation:
Linear functions are those whose graph is a straight line. A linear function has the following form

b is the constant term or the y intercept. It is the value of the dependent variable when x = 0.
m is the coefficient of the independent variable. It is also known as the slope and gives the rate of change of the dependent variable.
We know that
- At 104 chirps per minute, the temperature is 63 ºF.
- At 176 chirps per minute, the temperature is 81 ºF.
This information can be converted to Cartesian coordinates (x, y). Where x = the number of chirps per minute and y = the temperature in ºF.
To find a linear function that let us find the outside temperature from how fast crickets chirp we must:


Solving for b

Therefore, the linear function is

Now, using this linear function we can know the temperature when we know the chirps per minute:
For 124 chirps per minute the temperature is:

For 68 chirps per minute the temperature is:
