Answer:
It's the first one
Step-by-step explanation:
Answer: A <em>(first option)</em>: y-intercept = 9, zeros = {1, -1, 3, -3}
<u>Step-by-step explanation:</u>
The y-intercept is where the graph crosses the y-axis.
The zeros are the x-intercepts which is where the graph crosses the x-axis.
The graph touches the y-axis when y = 9
The graph touches the x-axis when x = -3, x = -1, x = 1, and x = 3
Step-by-step explanation:
sum of 2 angles on a straight line = 180°
therefore,
y + 120 = 180
y = 180 - 120 = 60
y = 60°
now apply angle sum property of triangle
now,
50 + x + y = 180
50 + x + 60 = 180
110 + x = 180
x = 180 - 110
x = 70
therefore, x = 70 & y = 60
hope this answer helps you dear! take care
Answer:
c
Step-by-step explanation:
consider points (0,2) and (-4,0)
slope=(0-2)/(-4-0)=-2/-4=1/2
y-intercept=2
y=mx+c
y=1/2 x+2
Given:
f(x) = 620e^7.8x
The standard equation for an exponential function is f(x) = Aoe^bx
where Ao is the initial amount
b is the growth factor
so, in this case, the initial amount is 620 and the growth factor is 7.8
