We need a line to answer this question...
Answer:
-7/8 the first one
Step-by-step explanation:
they're both the same
Answer:
B.
Step-by-step explanation:
The zeroes are 0 and 4 and the vertex is at (2, -4).
f(x) = (x - 2)^2 - 4
a) x=4
10+2x+6=24
-2x. -2x
10+6=-2x+24
-24. -24
10+6-24=-2x
simplify
-8=-2x
divide both sides by -2
4=x
2. x=7
14+3x+5=40
-3x. -3x
14+5=40-3x
-40. -40
14+5-40=-3x
-21=-3x
divide both side by -3
7=x
X+y=6 is.....
solve for x=0... y=6
solve for y=0... x=6
intersect x-axis at (6,0)... calculate the slop: solve for x=1... 1+y=6... 6-1= 5 y=5
calculate the slope: a= y(x=1)-y(x=0)/1=-1
x+y=6
