Answer: Y=(
) x-7
Step-by-step explanation:
A reciprocal is just when you flip over the numerator and the denominator.
So, if you have 5/8, then its opposite, or reciprocal will be 8/5. It is also a fraction, as is 5/8.
You can write it as a mixed number, as the person above me mentioned, as 1 3/5.
Multiply 7.22 onto 10b and -3
new equation - 72.2b-21.66=7b-14
add 21.66 onto -14
new equation - 72.2b=7b+7.66
subtract 7b from 72.2
new equation: 65.2b=7.66
divide 65.2 from b
new equation: b=7.66/65.2
final answer: b=0.117
Part A
5x - 5 >= 10 or-3x + 1 > 13
1) This is a disjunction (OR)
5x - 5 >= 10
5x >= 15
x >= 3
or
-3x + 1 > 13
-3x > 12
x < -4
Answer
x <- 4 or x >= 3
Part C:
1) This is a conjunction (And)
5x+ 3 <= 18 and 4 - x < 6
5x <= 15 and - x < 2
x <= 3 and x > -2
Answer
-2 < x <= 3
4x-8=9x+2
4x=9x+10
-5x=10
5x=-10
x=-2
