Y = kx, k being a constant
--------------------------------------
Find k :
--------------------------------------
When x = 12, y = 3
3 = k(12)
k = 3/12
k = 1/4
Equation : y = 1/4 x
--------------------------------------
Find y when x = 20:
--------------------------------------
When x = 20,
y = 1/4 (20)
y = 5
--------------------------------------
Answer: y = 5
--------------------------------------
Subtitute a = b + 1 to a + b = 1.1
b + 1 + b = 1.1
2b + 1 = 1.1 |subtract 1 from both sides
2b = 0.1 |divide both sides by 2
b = 0.05
Subtitute the value of b to a = b + 1
a = 0.05 + 1 = 1.05
Answer: a = 1.05 and b = 0.05
Answer:
ii
Step-by-step explanation:
Answer:
p = -7/2
Step-by-step explanation:
Distribute to get 2p+4<−2p−10
Add 2p to both sides
Subtract 4 from both sides
4p<-14
Divide both sides by 2
-7/2
