Answer:
f(1) = - 2
Step-by-step explanation:
f(1)
Means find the value of y when x = 1
From the graph the point (1, - 2)
is the point where y is - 2 and x is 1
Thus
f(1) = - 2
Answer:
C
Step-by-step explanation:
2.88*2.2=6.336, which is approximately 6.34.
Answer:
150 units³
Step-by-step explanation:
l * w * h = volume, so...
10*5*3 = volume
150 = volume
Answer:
y = -5x/4 - 8
Step-by-step explanation:
Two lines that are perpendicular have slopes that are opposite reciprocals.
Since the slope of the given line is 4/5, the opposite reciprocal of that is -5/4. So the equation has a slope of -5/4.
Since we know the coordinate of a point of the other equation, we can plug that into the point-slope form equation y - y1 = m(x - x1):
y - 2 = -5/4(x-(-8))
Simplify:
y - 2 = -5/4(x+8)
y - 2 = -5x/4 - 10
So the equation in slope-intercept form is:
y = -5x/4 - 8
I believe the anwser is c.
