(a). To calculate Y at equilibrium
Y = C + I + G
Y = 40 + 0.8(Y – 0 + 10 + 20)
Y = 350
(b). To calculate C, I and G at Equilibrium
C = 40 + 0.8 Y
Since Y = 350
C = 40 + 0.8(350)
C = 40 + 280
C = 320
I = 20
G = 10
(c).To find
equilibrium Y
Given,
EX = 4 + 3EP/P
IM = 8 + 0.1 (Y - T) - 2EP/P
E = 3
P = 1
P = 1.5
Y = 170
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360°
Answer:
360,000
Step-by-step explanation:
2/3 ÷ 240,000 = 2/3 ×1/240,000 = 1/3 × 1/120,000 = 3×120,000= 360,000
Answer:
D: (1, 4)
Step-by-step explanation:
You can either solve by substitution or elimination. If you are timed, the fastest way is to guess and check (plug-in the answer choices)
I will be using substitution to solve this:
Step 1: Since you have y already, you can set them equal to each other
x+3 = 3x+1
3 = 2x +1
2 = 2x
x = 1
Step 2: Now you have x, plug x into one of the original equations. In this case, I will use the first one
y = 1 + 3
y = 4
Step 3: Now write your answer as a coordinate plane point
x = 1, y = 4
(1, 4)
Answer: Choice C. (x-7)(x-8)
-------------------------------------------------------
Find two numbers that...
* Multiply to 56 (last term)
* Add to -15 (middle coefficient)
Those two numbers are -7 and -8. So that's why x^2-15x+56 factors to (x-7)(x-8)
