the coordinates of point f is B)7,-5
F(x)=-1x-1
1) Pick 2 points on the line (i chose (-4,3) and (3,-4)
2) Find slope of the line using the 2 points. (work below)
3) Find y-intercept, which is the point where y-axis and the line cross (y-intercept is -1).
4) Place both slope and y-intercept into slope-intercept form, y=mx+b (m=slope and b=y-intercept.)
5) Change y to f(x) (meaning function of x).
Work:
3-(-4)/-4-3=3+4/-4-3=7/-7=-1
y-intercept equals -1 also.
y=mx+b
y=-1x+(-1)
y=-1x-1
f(x)=-1x-1<---Answer
Answer: f(2)=15, f(-2)=18, all real #s
Step-by-step explanation:
1. f(2)=4(2)^2-2+1=16-1=15
2. f(-2)=4(-2)^2-(-2)+1=16+3=18
One pound is 16 oz. just multiply 22 by 16 and boom, there's your answer
Answer:
(5y-2)x(2x+5)
Step by step explanation:
10xy-4x+25y-10
Factor out 2x from the expression
2x*(5y-2)+25y-10
Factor our 5 from the expression
2x*(5y-2)+5(5y-2)
Factor out 5y-2 from the expression
(5y-2)x(2x+5)
