Let, the weight before 3 years = x
Then, it would be: x * 150/100 = 45
x * 1.5 = 45
x = 45/1.5
x = 30
So, your final answer is 30 Pounds
Hope this helps!
Answer:is there another triangle or is it just that one?
Step-by-step explanation:
Answer:
4=7/4*4-3
Step-by-step explanation:
Since the equation for a line is <em>y=mx+b </em>(where <em>m </em>is the slope and <em>b </em>is the y-intercept), we can fill in part of the equation with the coordinates. So far we have- <em>4=m4+b. </em>We can then add the slope into the equation, turning it to <em>4=7/4*4+b. </em>To find the y-intercept, you replace <em>x </em>with zero and solve for <em>y. So, </em>lets multiply <em>7/4 </em>and <em>4 </em>and simplify the equation to <em>4=(7*4)/4+b.</em> Next, we'll simplify the right side, turning the equation to <em>4=7+b. </em>Now, all we have to do is subtract <em>7 </em>from the right side of the equation, leaving us with the result of <em>b=-3.</em> We'll add that into our equation now, giving us our answer of 4=7/4*4-3
Answer:
a)
Completing the square
b)
You can prove that is always positive, stating;
The sum of two squared numbers can't be negative. Hence is always positive.
Also, if we take the discriminant of
Once the discriminant is negative, the quadratic has no real root. So, the function never touches the real axis and the function lies above or below the real axis. If we take x as 0, y = 20, therefore, the function lies above the real axis. It is always positive.
