law's of exponents
e^(x-5)*e^(3x+8) = 19
e^(x-5+3x+8) = 19
e^(4x+3) = 19
take the natural log, which is base "e" of both sides.
ln[e^(4x+3)] = ln[19]
4x +3 = ln[19]
4x = ln[19] - 3
x = (ln[19] - 3) / 4
x = -0.0139
Answer:
That is a positive slope because it's going upward
Step-by-step explanation:
Answer:
supplementary
Step-by-step explanation:
Angles 2 and 3 form a straight line. Straight lines are supplementary
Step-by-step explanation:
y = mx + c
m = y2 - y1 / x2 - x1
m = 7-3 / 2-0
m = 4/2 = 2
using the first x and y values in the equations if a line
3 = 2(0) + c
c = 3
so substitute the values into the eqn
y = 2x + 3
M = -1/2
y-intercept = (0, 1)
y = -x/2 + 1 in slope-intercept form
x/2 + y = 1
x/2 + 2y/2 = 2/2
x + 2y = 2 in standard form
