We are given
two ratios as
First ratio:
we can simplify it
Second ratio:
we can simplify it
we can cancel 4
so, both ratios are same
so, they are proportional..........Answer
Answer:
-10 < x < -8
Step-by-step explanation:
Envision a number line. There is one whole number, -9, and and an infinite amount of fractions (rational numbers) and irrational numbers between -10 and -8.
X could be any of those values.
The answer to the first part is (4,1).
The answer to the second part is (11,2).
Answer:
= 570
Step-by-step explanation:
Priority in order:
- Bracket
- X and /
- + and -
(50 x 40 / 4 + 20) + (50 / 2 + 25)
= (2000 / 4 + 20) + ( 25 + 25)
= ( 500 + 20) + ( 50 )
= ( 520 ) + 50
= 520 + 50
= 570
Simply plug 7 for each value of x
f(7)= -3(7) + 6
f(7)= -21 + 6
f(7)= -15
