Answer: (-2, 5) and (2, -3)
<u>Step-by-step explanation:</u>
Graph the line y = -2x + 1 (which is in y = mx + b format) by plotting the y-intercept (b = 1) on the y-axis and then using the slope (m = -2) to plot the second point by going down 2 and right 1 unit from the first point:
y - intercept = (0, 1) 2nd point = ( -1, 1).
Graph the parabola y = x² - 2x - 3 by first plotting the vertex and then plotting the y-intercept (or some other point):
vertex = (1, -4) 2nd point (y-intercept) = (0, -3)
<em>see attached</em> - the graphs intersect at two points: (-2, 5) and (2, -3)
Remember, -(-x)=x because the negatives cancel out
so
when p=-6 and q=7
p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16
Answer:
Select all the lines with slope 
.
Step-by-step explanation:
Use the slopes to help you answer this kind of questions.
The slope of the line going through: (1, - 2) and (3,4) is given by:
We plug in the coordinates to get:
All lines that are perpendicular to this line has slope .
The answer would be that the dot falls on the point (0,4)
Newborn = 18 inches
adult boa = 9 * 18 + 2 = 164 inches
Since all the information is given, then merely put the necessary facts in order.
Had the length of the newborn been unknown, it would have been represented by x.
9x + 2 = 164
9x = 164 - 2
9x = 162
9x/9 = 162/9
x = 18
