<em>7=a-5. What does a equal?</em>
<em />
<em />
When solving an equation, it's always a great idea to make sure all variables are on the left side of the equation and the numbers are on the right.
Since in our equation, we have numbers on both sides, we need to move all numbers to one side:-
7=a-5
This is the same as
a-5=7
Now, add 5 on both sides:-
a=12
So we conclude that a=12.
<h3>Good luck with your studies.</h3>
3x + 10 < 1
Subtract 10 from both sides:
3x < -9
Divide both sides by 3:
X < -3
Since x needs to be less than -3 the greatest internet would be -4
For solving a question like this where you have to find a function for a particular value, just put the given number in place of the unknown variable i.e. x in this case. Lets solve this function now.
We are to solve for f(9), so we will put 9 in place of x:
f(x) = 72+4x
f(9) = 72 + 4(9)
f(9) = 72 + 36
f(9)= 108
so, your function for the value 9 is 108.
The solution to this similar triangles is; XY = 11.25
<h3>What is the ratio of the similar triangles?</h3>
In triangle ABC, we see that;
AB = 5, BC = 12, CA = 8.
In triangle XYZ;
XY = N, YZ = 27 ZX = 18
To find:
The length of XY
If two triangles are similar, then their corresponding sides are proportional.
Since ΔABC is similar to ΔXYZ, then we say that;
AB/XY = BC/YZ = CA/ZX
5/N = 12/27 = 8/18
Cross multiply to get;
8N = 18 * 5
N = 90/8
N = 11.25
Thus, the solution is XY = 11.25

It is not linear because x is raised to the second power. Therefore it is not straight and would be kindof like a rainbow cut in half on the graph..
