Answer:
independent system
Step-by-step explanation:
The first linear equation () can be written in slope y-intercept form by solving for the y variable. When it is in that form, one can easily understand its geometrical shape and distinguish if it the same, if it crosses or if it is parallel, to the second line ()
We proceed to re-write it in slope y-intercept form:
Therefore it has a slope of "-1" and a y-intercept of "-5", while the second line has slope "1" and y-intercept "-7".
Therfore, they are lines that intercept at a unique point, and therefore represent an independent system.
The pic is really faint. Plz make it eazier to see.
The answer is ABC plus 124
Answer:
The measure of angle LKJ is 49°
Step-by-step explanation:
<u><em>The correct question is</em></u>
The equation tan−1 = {8.9/7.7} x can be used to find the measure of angle LKJ. What is the measure of angle LKJ?
Round to the nearest whole degree.
see the attached figure to better understand the problem
Let
x -----> the measure of angle LKJ
we know that
so
using a calculator
Round to the nearest whole degree
therefore
The measure of angle LKJ is 49°
The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle
width of the blanket = x
length of blanket = x +2
area = length * width
area = x * (x+2)
= x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0 or x + 6 = 0
x = 4 or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
