So my brother is seriously struggling with these every day and he is really sad right now it would mean a lot to me if you'd ans
wer these 2 questions :)
1. csc2(x) - 2csc(x)cot(x) + cot2(x) = tan2 (x/2)
2. [cos cos (x) cos(y)] [tan tan (x) + tan tan(y)] = sin(x + y)

Answer:
Step-by-step explanation:
<u>Dilation is applied by the rule:</u>
- (x, y) → (kx, ky), where k is the scale factor
<u>We have</u>
- (x, y) = (-2, 3) and (kx, ky) = (-8, 12)
<u>Substitute and solve for k</u>
- -8 = -2k and 12 = 3k ⇒ k = 4
<u>So the rule is</u>
7x + 18 > -3
7x > -21
x > -3

Answer:
Z is less than or equal to 6
Step-by-step explanation:
Y-5=3(x+1)
y-5=3x+3
add 5 to both sides
the answer would be y=3x+8
