Answer:
f(x) = y
Step-by-step explanation:
f(x) always equals y, so the equation would be y = 7. therefore, I am pretty sure that x = y, but you may want to wait to ask your teacher. If there is more detail, message me!
Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)

Step-by-step explanation:
<em>Given: Side lengths of a right triangle 3,4 and 5 units.
</em>
<em>
To draw: A right triangle with the given side length.
</em>
<em>
Solution:
</em>
<em>
We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.
</em>
<em>
From the given side length,
</em>
<em>
Hypotenuse = 5 unit
</em>
<em>
We can take any of the base and perpendicular.
</em>
<em>
Let, Base = 3 unit
</em>
<em>
Perpendicular = 4 unit.
</em>
<em>
It a right-angle triangle with a hypotenuse 5 unit.
</em>
<em>
Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.</em>
Since they are FEWER than 30 total cones, the sum of x small cones and y large one must be LESS THAN 30: x+y <30
He needs AT LEAST a dozen (12), so that means that 12 will work or more than 12:
