Hello,
answer D (-2,3)
Indeed
y=4x+11
y=-2x-1
==>4x+11=-2x-1
==>6x=-12
==>x=-2
And y=4*(-2)+11=3
The coordinates are (-3/4, 1/2)
this is also equivalent to (-0.75, 0.5) if that helps understand if further!
Answer:
In geometry, you can use deductive rules to prove that a given statement or conjecture is true or false using deductive reasoning.

Answer:
radius: 3 units <----> Circumference: 18.84 units
Diameter: 12 units <----> Circumference: 37.68 units
Diameter: 36 units <----> Circumference: 113.04 units
Radios: 5 unites <----> Circumference: 31.4 units
Step-by-step explanation:
How I got the answers for the radiuses:
3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)
3 x 2 = 6
C = pi x d
C = 3.14 x 6
C = 18.84 [this is the first radios]
5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)
5 x 2 = 10
C = pi x d
C = 3.14 x 10
C = 31.4 [this is the second radios]
How I got the diameters:
12 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 12
C = 37.68 [this is the first Diameter]
36 (this is the full diameter so we do not have to multiply it by 2)
C = pi x d
C = 3.14 x 36
C = 113.04 [this is the second Diameter]
Answer:
40
Step-by-step explanation:
Substitute the variable, x, with 4
3(4) + 7 (4)
Multiply
3(4)= 12
7(4)= 28
12 + 28 = 40
