Answer:
This equation has <u>No Solutions. </u>
Step-by-step explanation:
It is parrel because it has the same x. When equations have the same x it is always parrel or it always has no solutions.

Answer:
y = -4x+4
Step-by-step explanation:
Pick two points on the line
(0,4) and (1,0)
We can find the slope
m = (y2-y1)/(x2-x1)
= (0-4)/(1-0)
= -4/1 =-4
We know the y intercept is 4
The slope intercept form of the equation is y = mx+b where m is the slope and b is the y intercept
y = -4x+4
Answer:
16 units
Step-by-step explanation:
6.1 + 5.8 + 4.1 = 16
Answer:
C
Step-by-step explanation:
Calculate AC using Pythagoras' identity in ΔABC
AC² = 20² - 12² = 400 - 144 = 256, hence
AC =
= 16
Now find AD² from ΔACD and ΔABD
ΔACD → AD² = 16² - (20 - x)² = 256 - 400 + 40x - x²
ΔABD → AD² = 12² - x² = 144 - x²
Equate both equations for AD², hence
256 - 400 + 40x - x² = 144 - x²
-144 + 40x - x² = 144 - x² ( add x² to both sides )
- 144 + 40x = 144 ( add 144 to both sides )
40x = 288 ( divide both sides by 40 )
x = 7.2 → C
