The Y^2 because 4 to the power of 2 would give you 4x4 which gives you 16
D (-4; -2)
C (1; 2)
M (x; y)
DM+MC=CD
CM:MD=1:3
M: x= x(C)-(x(C) - x(D))/4=1-(1-(-4))/4=1 - (6/4)=1 - 1,5= - 0,5
M: y=y(C)-(y(C) - y(D))/4=2-(2-(-2))/4=2 - (4/4)=2 - 1=1
M(x; y)=M( -0,5; 1)
Answer:
x = ± 15
Step-by-step explanation:
Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides
- 0.5x² = - 112.5 ( divide both sides by - 0.5 )
x² = 225 ( take square root of both sides )
x = ±
= ± 15
Y > x
y = 2(3+x)
y = 3x-2
------------------------------
2(3+x) = 3x-2
2(3+x) - (3x-2) = 0
6 + 2x -3x + 2 = 0
8 -x = 0
x = 8
---------------------------
y = 2(3+x) = 2(3+8) = 22
y = 3x-2 = 3*8 -2 = 22
----------------------------------
x = 8 ; y = 22
