Answer:
no
Step-by-step explanation:
Y = mx + b
slope(m) = -3/4
(-2,5)...x = -2 and y = 5
now sub and find b, the y int
5 = -3/4(-2) + b
5 = 3/2 + b
5 - 3/2 = b
10/2 - 3/2 = b
7/2 = b
so ur equation is " y = -3/4x + 7/2....or 3x + 4y = 14
now it is just a matter of subbing in ur answer choices to see which ones work.
3x + 4y = 14...subbing in (6,-1)
3(6) + 4(-1) = 14
18 - 4 = 14
14 = 14 (correct).....so (6,-1) is a point on ur line <==
Step-by-step explanation:
Correction:
1⟩
Given equation is x²-3x = 4
⇛ x²-3x -4 = 0
⇛ x²+x-4x-4 = 0
⇛ x(x+1)-4(x+1) = 0
⇛ (x+1)(x-4) = 0
⇛ x+1 = 0 or x-4 = 0
⇛ x = -1 or x = 4
2.⟩
Given equation is x²+4x+4 = 0
⇛ x²+2x+2x+4 = 0
⇛ x(x+2)+2(x+2) = 0
⇛ (x+2)(x+2) = 0
⇛ x+2 = 0
⇛ x = -2
Answer:
The answer would be 12
Step-by-step explanation:
A large MAD (mean absolute deviation) tells us that there is a lot of variation in the ages of the swimmers. It tells us specifically that there are a lot of swimmers that are not close the to the age of 10 (which is the mean).
