Answer:
It usually works to follow instructions.
Step-by-step explanation:
<h3>Exercise 1.</h3>
Apparently, you are to plot the given points on the graph. The axes are clearly labeled, so it is a matter of identifying the appropriate grid crossing and putting a dot there. See the first attachment.
<h3>Exercise 2.</h3>
You can read the desired values from the graph you just plotted (as the instructions say), or you can simply read them from the table.
- 2 million
- 5 million
- 9 million
<h3>1. </h3>
See the red line and points in the second attachment. Usually, values on the axes of a graph will <em>increase</em> up and to the right.
<h3>2.</h3>
See the purple line and points in the second attachment.
<h3>3.</h3>
The point of intersection is (price, quantity) = (40, 350).
Answer:
x = -5/2
Step-by-step explanation:
From the quadratic equation
the axis of symmetry for quadratics of the form
y = ax² + bx + c is
x = -b/2a
x² + 5x + 9
x = -5/2
If three times the sum of eight and a number is sixty, then you need to break it down to write it out. First, we know we're multiplying 3 * (times) something. That something is 8 and a number, or x. So it'd be 8 + x. So we have 3 * (8 + x). And we know that equals 60, so we have 3 * (8 + x) = 60
