I believe its 2 and 1/2
I'm so sorry if its not but I would guess it is :)
Answer:
x = 10
Step-by-step explanation:
9 is to 45 as 2 is to x
9 ---- 45
2 ---- x
x = 2 . 45 / 9
x = 10
Reflection across the x-axis because all y-coordinates for triangle DEF are the opposite for the y-coordinates in triangle D'E'F'.
First, the number given in <em>g(x)</em> is 4, so look at the graph. You need to find that number that makes one of the statements true.
The true statement is at 4≤<em>x</em><8, because 4≤4, and 4<8, so replace the x on equation 0.5x+10 with 4.
0.5(4)+10
0.5 × 4 = 2
2+10 = 12
So, the value for <em>g(4)</em> is <em>12.</em>
your equation is:
a² + b² = c²
So, plug in what you know.
5² + 12² = c²
5² means 5*5, so your "a" is equal to 25
12² means 12*12, so your "b" is equal to 144
25 + 144 = c²
to this part, add a and b. you'll get 169.
169 = c²
next, use your calculator and square both sides.
√169 = √c²(you don't really have to do anything with the c, just get rid of the ²)
squaring both sides will get rid of the ² in c, and will give you your new number:
c = 13
