Answer:
x = 1
, y = 3
Step-by-step explanation:
y = -2x + 6 --- Equation 1
y = 4x - 1 --- Equation 2
Since both (-2x + 6) and (4x - 1) have the same total, y, they are equal.
-2x + 6 = 4x - 1
Isolate the like terms.
6 + 1 = 4x + 2x
Evaluate like terms.
6x = 7
Find x.
x = ![\frac{7}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B6%7D)
x = 1
Substitute x =
into Equation 2:
y = 4x - 1
y = 4(
) - 1
= 4
- 1
y = 3
Answer:
(0,1)
Step-by-step explanation:
There is a solution where the two equations intersect, therefore:
3x+1=2x+1
3x-2x=1-1
x=0
If we plug this 0 value into the x of both equations, we get a y value of 1:
y=3*0+1
y=0+1
y=1
OR
y=2*0+1
y=0+1
y=1
Therefore, there is a solution at (0,1)

Answer:
i) the value of a = 0 is non-permissible
ii) the value of b = 0 is non-permissible
Step-by-step explanation:
i) the given expression is ![\frac{5a^{2} + 80a }{50ab^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B5a%5E%7B2%7D%20%2B%2080a%20%7D%7B50ab%5E%7B2%7D%20%7D)
ii) if a = 0 then the expression will become infinity hence the value of a = 0 cannot be used
iii) if b = 0 then the expression will become infinity, hence the value of b = 0 also cannot be used.
iv) In the numerator of the expression if it is factorized we get 5a
( a + 16)
if a = -16 then the value of the expression becomes zero.
Answer:
8.4 is the average of all of the scores.
Step-by-step explanation:
Add all of the scores together, and then divide by the number of scores to get the answer. Btw, BNHA is the best lol. Hope this helps! :)
