Answer:
P(- 4, - 8 )
Step-by-step explanation:
The abscissa is the x- coordinate and the ordinate is the y- coordinate.
Here b = 2a , thus
a + 2a = - 12
3a = - 12 ( divide both sides by 3 )
a = - 4
and b = 2a = 2 × - 4 = - 8
P(- 4, - 8 )
Answer:
4.5 cm
Step-by-step explanation:
Circunference = 2π*radius = 2*3.14*radius = 6.28*radius = 28.26
so radius = 28.26/6.28 = 4.5 cm
Answer:
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So, (8,10) is not included in the solution area for the system.
Step-by-step explanation:
Distribute: 4x - 2 - 100 = 0
add 102 to both sides: 4x = 102
Divide both sides by 4: x = 25.5
