Answer:
A. y=-1/3x+10
Step-by-step explanation:
Perpendicular gradients(slopes) are negative reciprocals so
m=-1/3 then use the point (6,8) to find the equation of the line
y=mx+b
8=(-1/3)(6)+b
8=-2+b
b=10
y=-1/3x+10
Answer:
[-1, 6)
General Formulas and Concepts:
<u>Algebra I</u>
- Reading a coordinate plane
<u>Algebra II</u>
- Range is the set of y-values that are outputted by function f(x)
- Interval Notation - [Brackets] denote inclusion and (Parenthesis) denote exclusion
Step-by-step explanation:
According to the graph, our y-values span from -1 to 6. Since -1 is a closed dot, it is inclusive. Since 6 is an open dot, it is exclusive:
Range would then be [-1, 6).
If you would like to know whether or not what she wrote is accurate, it is.
Hope that helps!
Answer:
B.
Step-by-step explanation:
You have to use the number in the variable to figure out if the number multiplied by 3.5 goes over 20 dollars. The highest you can go without going over 20 dollars is 5 notebooks
