2x^2 + 8x = 0
2x(× + 4) = 0
2x = 0
x = 0/2 =0
x + 4 = 0
x = -4
8724/25 = 348.96
When you say "over" that means that it has to be divided that short subtraction sign that separates the numerator and the denominator and also means divide so I believe that if you divide you can find the decimal.
Answer:
y = x - 1 (third answer choice)
Step-by-step explanation:
From the given we see immediately that the slope of this line is -1. The slope of a line perpendicular to this one is +1, which is the negative reciprocal of -1. The slope-intercept form is y = mx + b. To find b, the y-intercept, we make the following substitutions: m = -1, y = -2, x = -2:
-2 = +1(-2) + b, or +1 = 2 + b, or b = -1
and so the desired equation is y = x - 1 (third answer choice)
Given:
The location of point S on a coordinate plane.
To find:
The ordered pair for the point S.
Solution:
A point is defined as (x,y), where, |x| is the distance between the point and y-axis, and |y| be the distance between the point and x-axis. Signs of coordinates depend on the quadrant.
From the given graph it is clear that,
Distance between S and y-axis = 3.5
Distance between S and x-axis = 5.5
Point S lies in 3rd quadrant, it means x- and y-coordinates are negative.
Therefore, the ordered pair of point S is (-3.5,-5.5).
