Answer:

If you input a value of x then we get the output f(x) = y, which is the function of x. This is a function of x. Hence, x² = y is a function of x.

Need help on 9 don’t know if I did it right or not but I need help :p

solmaris [256]

Answer:

9b) -8 = y

9a) 72° = m∠ABC

Step-by-step explanation:

Since you have an angle trisector, in this case, m∠CBE ≅ m∠DBA, therefore you set x equal to 8, plus, according to Morley's Trisector Theorem, all three angles form an equilateral triangle, so m∠BOC also has to equal 24°:

${8}^{2} - 5(8) = 64 - 40 = 24 \\ \\ 6(8) - 24 = 48 - 24 = 24 \\ \\ 2(8) - y = 24 >> 16 - y = 24 >> -8 = y$

Then, m∠ABC comes from multiplying 3 by 24 [three twenty-four's], which results in 72°.

Find the measure of angle2 A. 90 B. 50 C. 60 D. 30

galina1969 [7]

I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense

Which function g represents the exponential function f(x) = 5x after a vertical stretch by a factor of 2 and a reflection across

irinina [24]

Answer:

g(x) = -2 • 5^x

Step-by-step explanation:

the reflection across the x-axis makes the equation negative. the 2 is the verticals stretch.
