3. 18d-12
4. x=9
Step-by-step explanation
Hope this helps. I'm very sorry if I'm wrong
Step-by-step explanation:
PART 1:
on the graph you can make a triangle at any point and with any angle measures.
i recommend a smaller right triangle to be easiest.
i recommend the points (0,3) A (3,0) B and (0,0) C
∆ABC angle measurements:
m∠CAB=45°
m∠ABC=45°
m∠ACB=90°
PART 2:
(4,3) D (7,0) E and (4,0) F make an identical right triangle moved 4 squares to the right
m∠FDE=45°
m∠DEF=45°
to find the missing value of the angle EFD we will use subtraction and addition
180-(45+45)
180-90
90
therefore, the m∠EFD=90°
PART 3:
both the angle measures and the shapes of the triangles are the same
PART 4:
i used a 1:1 ratio
sorry for the wait :)
Answer:
output = 23
Step-by-step explanation:
x = -4
f(x) = 3ǀ2x - 1ǀ + x
f(x) = 3ǀ2(-4) - 1ǀ + (-4)
f(x) = 3ǀ2(-4) - 1ǀ - 4
f(x) = 3ǀ-8 - 1ǀ - 4
f(x) = 3ǀ-9ǀ - 4
f(x) = 3(9) - 4
f(x) = 3(9) - 4
f(x) = 27 - 4
f(x) = 23
Answer:
y=2x-4 is linear while the other is quadratic.
