Answer:
(4, 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 11 → (1)
x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the term in y
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and evaluate for y
Substituting into (1)
2(4) + 3y = 11
8 + 3y = 11 ( subtract 8 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
Solution is (4, 1 )
Answer:
10:4, 35:14, 55:22
Step-by-step explanation:
4×5,384 = 4×5,000 +4×384
4×5,000 is very easy to answer (20,000)
so the hard part is find 4×384. You have already know the answer of 4×384 so you can find the true answer. ( 21536)
Answer:
The right answer is Option D: 
Step-by-step explanation:
Given that initial value of 3/2 and rate of change is -2/3
The given functions can be observed and it can be concluded that the functions are in the form
Here m is the slope which is also called rate of change and c is the y-intercept.
The y-intercept is the initial value when input is zero.
So we have to look for a function that has 3/2 in place of c and -2/3 in place of m.
From the given options,
is the matching function
Hence,
The right answer is Option D:
Answer:
No it doesn't
Step-by-step explanation:
It has two X values that means it can't be a function
