Answer:
a) The estimates for the solutions of
are
and
.
b) The estimates for the solutions of
are
and
Step-by-step explanation:
From image we get a graphical representation of the second-order polynomial
, where
is related to the horizontal axis of the Cartesian plane, whereas
is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:
a) ![4\cdot x^{2}-4\cdot x -1 = 0](https://tex.z-dn.net/?f=4%5Ccdot%20x%5E%7B2%7D-4%5Ccdot%20x%20-1%20%3D%200)
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:
,
b) ![4\cdot x^{2}-4\cdot x -1 = 2](https://tex.z-dn.net/?f=4%5Ccdot%20x%5E%7B2%7D-4%5Ccdot%20x%20-1%20%3D%202)
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

For the question in the photo:
y = 2.50x + 7.50
Domains:
0, 2, 3, 4, 5, 6, 7, 8, 9, 10
As you can’t ride 0.2 or 0.7 of a ride, for example, and you only have time for ten rides. Plus you have enough money to ride ten rides
For the drama club one:
C = 21t + 40
Is the correct answer as 40 is a set value and is not influenced by the amount of club members there are, x is the amount per shirt, and C is the cost
Answer:
1. 12/1= rate of change
Step-by-step explanation:
1.
1 mile= 30 seconds
(1,30)
6 miles= 1 1/2 minutes
6 miles=90seconds
(6,90)
Formula: y2-y1/x2-x1
90-30/6-1
60/5
12/1= rate of change
hope its right
