Hey! Your answer for this is
7x^2 + 3x^2 = 10x^2
-2x + 15x = 13x
9 - 4 = 5
Hence, 10x^2 + 13x + 5.
Hope this helps!
Hello,
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!

Answer:
it could be drawn using maths
Answer:
y = 
Step-by-step explanation:
Standard equation in point slope form is :
y-y_0 = m(x-x_0) +c
where m = slope = -1/2
(x_0,y_0) is the point from which the lines passes through = (5,-3)
We get the equation as,
y-(-3) = -1/2(x-5)
y+3 =
(x-5)
y = 
y = 
Hence, m= -1/2 and c = -1/2
Required equations is:
y = 
21/49
= (21/7) / (49/7)
= 3/7.
The final answer is 3/7~
