Well, if he walks 3 miles in 1hr, then divide the hour by 3 to get one mile in 20 min, then multiply it by 7 to get 2 hours and 20 min to walk 7 miles. Hope his helped!
You have to subtract 4.35 from 15.60 to see for all the children
3x+4.35 = 15.60
F(x) = x^2 -2x + 4
f(-2) = (-2)^2 -2(-2) +4
f(-2) = 4 + 4 + 4
f(-2) = 12
12 is your answer
Hope this helps
<u>Answer:</u>
Option C. The given system has two solutions.
<u>Solution:
</u>
The given equations are,
From the equation we can say,
We know that the quadratic formula to solve this,
x has two values which are
Here, a = (-1), b = 5 , c = -3
So,
Again
Hence, x has two solutions.
Answer:
X = 7/5
when the value of x is 7/5 the equation will be true
Step-by-step explanation:
To fine the value of x that makes the equation true, we equate the expression to zero to find the value of x.
Check attachment for processes
Therefore when the value of x is 7/5 the equation will be true
