that would mean he's 7 right now
Answer:
The answer to your question is:
x = -8; y = 1 ; z = -4
Step-by-step explanation:
Δ =
= 40 + 24 + 18 - (-4 + 45 - 96)
= 82 + 55
= 137
Δx =
= - 480 - 144 - 156 - ( 24 - 540 + 832)
= -780 -316
= - 1096
Δy =
= 40 + 24 + 18 - ( - 4 + 45 - 96)
= 82 + 55
= 137
Δz =
= 1040 - 360 - 72 - ( - 104 - 180 + 1440)
= 608 - 1156
= -548
x = -1096/ 137 = -8
y = 137 / 137 = 1
z = -548 / 137 = -4
Answer:
D
Step-by-step explanation:
Substitute the f(x) and g(x) into f/g
To find the domain,
Get the denominator of the fraction so 5x + 2 and equal it to 0 and find x
5x + 2 = 0
5x = -2
x =
Therefore it's D
To find the slope of a line, use this formula:
m = (y2-y1)/(x2-x1) where m is the slope, and (x1, y1) and (x2, y2) are points.
If I plug points P and Q into the slope formula, we get:
(1-5)/(-2+8) = -4/6 = -2/3
The slope is -2/3
X=1
8-2x=-8x+14
-2x=-8x+6
6x=6
x=1
