Answer:
a) Vertex is at (-3, -1)
b) y-intercept is at (0,8)
c) x intercept is at (-4,0) and (-2,0)
d) x=-3
Step-by-step explanation:
We know the vertex is the lowest or highest part of a parabola meaning all the points are reflected across. It is the only y value without a matching pair
E.x. -1 and 1, -3 and 3
The only point without a corresponding y value is (-3,-1) therefore the vertex is at (-3,-1)
The y-intercept is where the parabola meets the y axis or the x value is equal to 0, we just have to find when x = 0 to find the y intercept
y intercept: (0,8)
For the x intercept's it is just the reverse, you need to find where the parabola crosses the x axis or when y = 0
x intercept 1:(-4,0)
x intercept 2: (-2,0)
The axis of symmetry is also the x coordinate of the vertex which is 3 so
x = 3
Answer:
2
Step-by-step explanation:
5+1+7+x+3+2+4=x+22
x+22 is divisible by 3,
multiple of 3 are 3,6,9,12,15,18,21,24,27,...
if x=2 ,then x+22=2+22=24
so smallest number is 2
Answer:
Percentage Error in counting the marbles in the jar is 39.72%
Step-by-step explanation:
Estimated marbles in the jar = 44
Actual marbles in the jar = 73
⇒Error in Marbles = Number of actual Marbles - Estimated marbles
= 73 - 44 = 29
So, the error in counting marbles in the jar is 29.
Now, 
= 
or, Percentage Error = 39.72%
Hence, the Percentage Error in counting the marbles in the jar is 39.72%
The answer is B,D
