Answer:
Step-by-step explanation:
Since we know the values of a, b, and c, we can substitute them into our expression and get the value.
A negative multiplied by a negative gets us a positive.
Adding a negative is the same as subtracting a positive.
Hope this helped!
Answer:
1. B (40- 3n)
2.c (86)

Answer:
B
Step-by-step explanation:
Answer:
y = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
slope of line p = 8
y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0
So;
Slope of the line = 8
y-intercept = 3
Equation of the line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
y = 8x + 3
Answer:
AB = 3.16 units
Step-by-step explanation:
Given:
A(3, -1) and B(6, 0)
To Find:
AB = ?
Solution:
AB = root{(x2 - x1)^2 + (y2 - y1)^2}
AB = root{(6 - 3)^2 + (0 - (-1))^2}
AB = root{(3)^2 + (0 + 1)^2}
AB = root{9 + (1)^2}
AB = root{9 + 1}
AB = root 10
Therefore, AB = 3.16 units
