Answer:
The x-intercepts are the points at which the parabola crosses the x-axis, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x at which y=0
3+2=5, And 4-7=-3. 3 and 2, and 4 and 7
Answer:
See below
Step-by-step explanation:
<h3>Part A</h3>
Gas in liquid state at
- 40° F < t < 140° F
<h3>Part B</h3>
The graph is the line segment from the point -40 to 140 on the number line, with both points open circles and shaded in between those 2 points
Solution set is all numbers greater that -40 and smaller than 140.
<h3>Part C</h3>
-49° F is smaller than -40° F, so the gas would freeze
Answer: x=7/2, x=-3
Step-by-step explanation:
First lets do look at it without the absolute value marks
4x-1=13
4x=14
x=7/2
Now lets do the same but assume 13 is negative,
4x-1=-13
4x=-12
x=-3
