Answer:
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have
This is the equation of the line in slope intercept form
where
The given equation not represent a proportional relationship, because the line not pass through the origin
In a proportional relationship the value of b (y-intercept) is equal to zero
Is there supposed to be a picture attached? Or is it asking simply what number "base 10 blocks" represents. If so, the answer would be 10. Not sure if that's what the question is asking though! Hope this helps :)
Answer:
7.11
-7.1
Step-by-step explanation:
<span>(2x – 1)(x + 7) = 0
2x-1=0
2x=1
x=1/2
x=0.5
x+7=0
x= -7
</span>
-5 1/3, -2 1/2, 3.75, 4.2 ( this is the order from least to greatest)
