Answer:
From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0
Step-by-step explanation:
Given as :
Let The standard equation of line
y = m x + c
where m is the slope of line and c is y-intercept
For, x-intercept , put y = 0
For y-intercept , put x = 0
A) y = x + 3
for x-intercept , y = 0
So, 0 = x + 3
i.e x = - 3
B) y = x² + 3 x
for x-intercept , y = 0
So, 0 = x² + 3 x
i.e 0 = x² + 3 x
Or, x ( x + 3) = 0
Or, x = 0 , x = - 3
C) y = x² - 3 x
for x-intercept , y = 0
So, 0 = x² - 3 x
i.e 0 = x² - 3 x
Or, x ( x - 3) = 0
Or, x = 0 , x = 3
D) x = y² - 3 y
for x-intercept , y = 0
So, x = 0 - 0
i.e x = 0
Hence, From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0 Answer

Answer:
72
Step-by-step explanation:
20 got 4 added to it and the only number that gives you 24 when you multiply it is 4x6 and we can prove that to be right because the one before it is 4x5 and it gives us 20. Now that we know the multiplier is 5 and 6 we can ask ourselves, "What do I multiply by 5 that gives me 60?" And that is 12. So 12x6 is 72 for x.
Answer:
y=0.3x
Step-by-step explanation:
Formula = 
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.
