Answer:
x = -4
Step-by-step explanation:
Lets work on this :D
(6x × 2) - 18x = 24
=>12x - 18x = 24
=> -6x = 24
=> x = -4
Please give me brainliest if this helped! :D
If given a line in the slope-intercept form
y=mx+b
m is the slope and b is they y-intercept
These problems are based on the Pythagorean Theorem. The Pythagorean Theorem is a^2 + b^2 = c^2. If the two sides are equal, the triangle is a right triangle. If c^2 is less, the triangle is acute. If c^2 is more, the triangle is obtuse.
Obtuse: c^2 > a^2 + b^2
Acute: c^2 < a^2 + b^2
Right: c^2 = a^2 + b^2
#7 --- Obtuse
21^2 ___ 8^2 + 15^2
441 ___ 64 + 225
441 > 289
#8 --- Right
20^2 ___ 12^2 + 16^2
400 ___ 144 + 256
400 = 400
#9 --- Acute
6^2 ___ 4^2 + 5^2
36 ___ 16 + 25
36 < 41
Hope this helps!
Step-by-step explanation:
Part A:
car 1 => exponential function
car 2=> linear function
Part B:
car 1 => the function f(x) = 45,000 • (0.9)^x
car 2= > the function f(x) = 45,000 - (3,000)x
Part C:
after 13 years, the value of :
car 1 => 45,000 • (0.9)^13 = $ 11,438.40
car 2=> 45,000 - (3,000)(13) = $ 6,000
the difference is = 11,438.40 - 6,000
= $ 5,438.40
its better to Belinda to purchase car 1.
Probably a ponytail or just your hair down.
