Answer:

C: Chris made a mistake in step 2.

Step-by-step explanation:

There are 4 main exponent rules in mathematics. In step 1, Chris followed the correct rule of:

$(a^{x})(a^{y})=a^{x+y}$

However, in step 2, he messed up. The correct rule is:

$(a^{x})^{y}=a^{(x)(y)}$

This means that step 2 should have been $4^{-15}$

Hope this helps! :^)

Step 2 , supposed to be 4^-15 instead of 4^-2. Always multiply the exponents together.

7. In name the bisected angles 1 and 2. If is 4x  3y, can be determined in terms of x and y? If so, state in terms of x+ y expr

Ugo [173]

Answer:since there is no diagram i will answer to the best of my ability.

Step-by-step explanation:

If an angle is bisected then it is divided into 2 equal angles which i think they are naming 4x and 3y. In this case, 4x=3y. Solving for x, we get x= (3y)/4. Solving for y we get y= (4x)/3. Now if we substitute (4x)/3 for y in the equation x= (3y)/4 then x= (3(4x)/3)/4 = 4x/4=× so then we can say x÷y = measure of original angle that was bisected. Or znother way it can be said is x+y = 2x or x+ y =2y.
