Answer:
The cost of the lessons taken
Step-by-step explanation:
Let
y -----> the total paid for the baseball bat and the lessons
c ----> the number of lessons
we have
y=25c+75
This is a linear equation in slope intercept form
y=mx+b
where
b=$75 -----> the price of he baseball bat (y-intercept)
m=25 $/lesson ----> the slope of the linear equation
therefore
25c represent the cost of the lessons taken
Answer:
Step-by-step explanation:
A linear graph with y values (height of tree) going up 2.5 with each increase of x (growing season)
This is the model that best fits the graph describing a growth of a plant
Answer:
No
Step-by-step explanation:
Let's find the slope of both lines and then compare these slopes:
From (-4,3) to (-5,4) entails a decrease of -1 in x and an increase of 1 in y. Thus, the slope is m = rise / run = 1/(-1) = -1.
From (0,1) to (5,0) entails an increase of 5 in x and a decrease of 1 in y. The slope here is m = rise / run = -1/5.
For these lines to be parallel, their slopes must be the same. That is not the case here, so NO, the lines are not parallel.
Answer is B. second one
A = 1/8, B = 5/16, C = 7/12, D = 5/6
--------------
We are given the equation y = 2(x – 3)^2 – 4 and is asked for the domain and range of the following function. In this case, there is no radical sign so the domain includes all real numbers. The range has a minimum value of -4 since the squaring makes the value on the first term positive. Hence the answer is A.
