Answer:
rachael is 35 and sarah is 32.
Step-by-step explanation:
Answer:
A. False
B. True
C. False
D. True
Step-by-step explanation:
The values range from 0 to 6 not 1 to 6.
There is a peak at 3 since it has 5 datas.
The mean is 3.471 not 3.
The median IS 3.
Step-by-step explanation:
5x + 2x
that is the same as (5 + 2)x
and that is the same as (7)x = 7x
so, for the second part of the problem we are actually comparing
7x
and
7x - 1
there is therefore no way for the two expressions to deliver the same value for the same x.
the values of 7x are always larger by one than the values of 7x - 1
so, e.g.
x = 1
5×1 + 2×1 = 5 + 2 = 7
7×1 - 1 = 7 - 1 = 6
x = 2
5×2 + 2×2 = 10 + 4 = 14
7×2 - 1 = 14 - 1 = 13
x = 3
5×3 + 2×3 = 15 + 6 = 21
7×3 - 1 = 21 - 1 = 20
x = 4
5×4 + 2×4 = 20 + 8 = 28
7×4 - 1 = 28 - 1 = 27
x = 5
5×5 + 2×5 = 25 + 10 = 35
7×5 - 1 = 35 - 1 = 34
The x intercept is where the graph intercepts the x axis or where y=0
the y intercept is where the graph intercepts the y axis or where x=0
xintercpet
replace y with 0 and solve for x
-3x+4(0)=-36
-3x=-36
divide -3 both sides
x=12
xintercept=12
yintercept
replace x with 0 and solve for y
-3(0)+4y=-36
4y=-36
divide both sides by 4
y=-9
xint=12
yint=-9
C is answer
Answer:
(x-43.45)(x+7.45)=0.
Step-by-step explanation:
We have the quadratic equation 
i.e. 
Now, the roots of the quadratic equation 
are given by 
So, from the given equation, we have,
a = 1, b =-36 , c = -324.
Substituting the values in , we get,
i.e. 
i.e. 
i.e. 
i.e. 
and i.e. 
i.e. 
and i.e. 
i.e. x = 43.45 and x = -7.45
Hence, the factored form of the given expression will be (x-43.45)(x+7.45)=0.
