Answer:
4 x 3 - 1 x 20 = -8
H u m a n F i n g e r P i e.
remember, you can do anything to an equation as long as you do it to both sides
we can do a subsitution
y=x+6
y=-7x-10
since y=x+6, we can subsitute x+6 for y in the other equation
y=-7x-10
x+6=-7x-10
add 7x to both sides
8x+6=-10
minus 6 from both sides
8x=-16
divide both sides by 8
x=-16/8=-2
the valu eof x that satisfies both equations is x=-2
When trying to find a root of a number ( the little number included with the square root symbol) this is the same as raising the number to that fraction.
Example : ∛5 would be the same as 5^1/3
So in the given problem the 5th root can be written as x^1/5
Now the number is 13^3, so to simplify the 5th root, the value could be written as 13^3/5
Answer:
31°
Step-by-step explanation:
Transversal BD crosses parallel lines AB and CD, creating alternate interior angles ∠2 and ∠5. As you know, alternate interior angles are congruent, so have the same measure.
m∠5 = m∠2 = 31°
