Answer:
2(-1*x)-1=2(-1*x)-1+2(-1)
Step-by-step explanation:
-2+2x-1=-2+2x-1+-2
-3+2x=-3+2x-2
-3+2x=-5+2x
2x=-8+2x
0=-8
I probably messed up somewhere
PLEASE HELP MY GRADE DEPENDS ON THIS!!! Jackson sells lemonade for $2 per cup. he paid $20 for supplies to sell 5 cups. What is the domain for this scenario
Answer:
relationship between base and perpendicular is given by tan angle
tan angle = perpendicular/base
tan angle =21/41
angle =tan -¹(21/41)=27
We can use the pythagorean theorem to solve this
The pythagorean theorem = a^2 + b^2 = c^2, while
a = one leg
b = the second leg
c = the hypotenuse
In this problem,
a = 3
b = 15
c = ?
Let's plug our values into the pythagorean theorem
(3)^2 + (15)^2 = c^2
9 + 225 = c^2
Add together the left side
234 = c^2
Take the sqrt of both sides
sqrt(234) = c
The length of BC = sqrt(234)
Answer:
5ab + 8 - 1a^2.
Step-by-step explanation:
Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2
