Answer:
The answer is 2.
2 since 6/4=3/2
Step-by-step explanation:
Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)
If y=kx then y/x=k.
So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.
So we are going to solve this proportion:
Again I put y/x from each point. They should have same ratio because this is a direct variation.
Cross multiply:
Divide boht sides by 6:
Answer:
-12
Step-by-step explanation:
(-4) - 8
Keep Flip Change
Keep
(-4)
Flip
- to +
Change to opposite
8 to -8
Result
-4 + -8 = -12
The ansa is y= -2/3 or -2
x= 2 or 4/3
Answer:
x= {2+ i}/2 , {2- i}/2 = C
Step-by-step explanation:
4x² - 8x +5 = 0
using quadratic formula
x= {-b±√b²-4ac}/2a
x= [-(-8)±√(-8)²-4(4)(5)] /2x4 = [8±√64-80]/8= [8±√-16]/8 = {8±4 i}/8
x= {8+4 i}/8 , {8-4 i}/8
x=4 {2+ i}/8 , {2- i}/8
4 divides 8
x= {2+ i}/2 , {2- i}/2 = c
125, 216, 343, 512, 729
the numbers given in the sequence are recognisable as cubes
1 = 1³, 8 = 2³, 27 = 3³, 64 = 4³
the next five terms will be
5³ = 125, 6³ = 216, 7³ = 343, 8³ = 512 and 9³ = 729
