Answer:
x² + 2x - 48
Step-by-step explanation:
Given
(x - 6)(x + 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 8) - 6(x + 8) ← distribute both parenthesis
= x² + 8x - 6x - 48 ← collect like terms
= x² + 2x - 48
Use the linear combination method.
A.) (-3,12)
B.) (-3,13)
C.) (0,4)
D.) (-1,7)
Answer:
(D)(-1,7)
Step-by-step explanation:
We want to solve for x and y in the simultaneous equation
3x+y=4
2x+y=5
Subtract Equation 2 from Equation 1
x=-1
Substitute x=-1 into any of the equations to solve for x.
3x+y=4
3(-1)+y=4
-3+y=4
y=4+3=7
Therefore: (x,y)=(-1,7)

Answer:
2/3
Step-by-step explanation:
it starts off as 2:3 right? so the 3 is light soy sauce. if you want to turn the right soy sauce into 1 cup you have to divide 3 bye 3 which gives you one. then you also divide by 3 on the other side. that would be 2 divided by 3. 2 divided by 3 is the same as 2/3. so your answer is 2/3.
Answer:
7 years
Step-by-step explanation:
Given: A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year
To Find: Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members
Solution:
Total members in chess club= 500
chess club loosing members each year = 30
Number of members in chess club in year
Total members in Computer club= 150
chess club gaining members each year = 20
Number of members in chess club in year
Now,
When chess club and computer club have equal number of members
=
So,
It will take 7 years for two clubs to have the same number of members.
