Answer:
x = 5
Step-by-step explanation:
3x-1 = 5x-11
<em>Subtract 3x from both sides:</em>
-1 = 2x - 11
<em>Add 11 to both sides:</em>
10 = 2x
<em>Divide both sides by 2:</em>
5 = x
Answer:
(-1,4) is a solution to the system.
Step-by-step explanation:
For this problem, we can simply identify if this point is a solution by verifying the plugged in point values allow the left hand side to equal the right hand side.
(1) -2x - 3y = -10
-2(-1) - 3(4) ?= -10
2 - 12 ?= -10
-10 == -10
(2) -3x + y = 7
-3(-1) + (4) ?= 7
3 + 4 ?= 7
7 == 7
Since both equations are satisfied by this point, then we can say the point (-1,4) is a solution to the system. Additionally, this means this is a crossing point of the system of equations.
Cheers.
Answer:
1/8 i think
Step-by-step explanation:
Answer:

Answer:
64
Step-by-step explanation:
The common difference is 80 / (8 - 3)
= 16
So f(18) - f(14) = (18 - 14) * 16
= 54
