Answer:
y = -3
Step-by-step explanation:
4x – 3y = 17
x = 2
4(2) - 3y = 17
8 - 3y = 17
-3y = 9
y = -3
Answer:
try doing cross out way
Step-by-step explanation:
There are 78 cookies in box C, 26 cookies in box B and 10 cookies in box A.
let the number of cookies in first box be represented mathematically as B-16
the number of cookies in second box be represented as B
the number of cookies in third box be represented as 3B
Since there are 124 cookies we can make an equation such that it becomes
B-16 +B +3B =124
Solving for B, we have
5B -16 =124
5B =124 +16
5B =130
B=130/5
B=26
Therefore Box A contains B-16 =26-16 =10 cookies
Box C contains 3B =3 X 26=78 cookies

There exists a question that instead of >, the symbol used is ≥. Substitute the value of abscissas and ordinates of the points to x and y, respectively.
A. (1/4, 1) (3/2)(1) - 2(1/4) = 1 TRUE
B. (4, 1) (3/2)(1) - 2(4) = -6.5 FALSE
C. (1, 1/4) (3/2)(1/4) - 2(1) = -1.625 FALSE
D. (1, 0) (3/2)(0) - (2)(1) = -2 FALSE
E (1/4, 3/4) (3/2)(3/4) - (2)(1/4) = 0.625 FALSE
Thus, the answer is letter A.
