Answer:
C
Step-by-step explanation:
∠CDE = 0.5( mEC - m CE )
The arcs CE and EC must add to 360°, thus
arc EC = 360° - 105° = 255°, hence
∠CDE = 0.5(255 - 105)° = 0.5 × 150° = 75° → C
I'm taking the same final test.
The answer is y= 1/4x - 5
How? Well in this case we are using the formula y= mx + b
Substituting it with the given point (8, -3) and the slope 1/4
it'll look like -3 = 1/4 (8) + b
Next we solve.
-3 = 1/4 (8) + b
-3 = 8/4 + b
-3 = 2 + b
-2 -3 = b
-5 = b
so we now we know that b = -5.
All we have to do is substitute that into the equation to get our final answer (this time, without the point 8,-3).
Our answer in the end is y = 1/4x -5
16:29:15 I think that would be it but, I'm really sorry if that's not right
Well one similarity is that since you have to multiply, integer rules still apply and that you can also multiply variables. A difference is that with fractions, you have to make a number into an improper fraction rather than just the regular way which would most likely be the whole number with a decimal.
Answer:
A
Step-by-step explanation:
Reflection over the x axis means that for points A, B, and C, the sign of the y value would change. Since point A is (1, 1), a reflection over the x axis means that it would become (1, -1). We can do the same for points B and C and therefore the answer is graph A
