It’s the first one because the circle is filled in meaning that it’s greater or equal than
Answer:
LINEAR EQUATION f(x) = -2.5x+-5 The y- interpecrt is -5
Step-by-step explanation:
Answer:
Step-by-step explanation:
since the question does not have a given slope you can just put the point into the point slope formula y-y1 = m(x-x1)
y-5 = m(x-(-2))
y-5 = m(x+2)
since the slope is not given, leave it like that
The derivative of :
y = ( 2 x - 7 )³ - we will use the chain rule :
y = u³
y` = 3 u² · u`
y` = 3 ( 2 x - 7 )² · ( 2 x - 7 ) `
y ` = 3 ( 2 x - 7 )² · 2
y ` = 6 ( 2 x - 7 )²
So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
