Answer:
<h2>The x-interecepts are 5.6 and -1.4, approximately.</h2>
Step-by-step explanation:
The given equation is
Where 
, 
and 
, let's use the quadratic formula
Therefore, the x-interecepts are 5.6 and -1.4, approximately.
Ussed = x
biked = 75 + x
total trip = 325 = x + (75 + x)
325 = 75 + 2x
250 = 2x
x = 125
<span>biked = 75 + x = 75 + 125 = 200 km</span>
Answer:
7
Step-by-step explanation:
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
Next, we shall simplify (1/3 – 1/9)². This is illustrated below:
(1/3 – 1/9)² = ((3 – 1)/9)² = (2/9)²
[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴
= [(2/9)² + (1/3)³] : (1/3)⁴
= [4/81 + 1/27] : 1/81
= [(4 + 3)/81 ] : 1/81
= 7/81 : 1/81
= 7/81 ÷ 1/81
Invert
= 7/81 × 81/1
= 7
Answer:
faster
Step-by-step explanation:
25 in 20 minutes is 25/20 = 1.25 per minute
36 in 30 minutes is 36/30 = 1.20 per minute
The first rate is faster.
Answer and Step-by-step explanation:
2x + 2 is the answer.
If the boy is twice as old, and the sister's age is represented by <em>x</em>, then we multiply 2 to x to represent the boy's age.
Then we add 2 when 2 years pass by.
