Answer:
4th option
Step-by-step explanation:
The term that combines with 3x²y , must have variables x²y
The only other term with x²y is 8x²y
Answer:
5
Step-by-step explanation:
We cannot repeat an x value for the relation to be a function
Since x=3 ,4, 7 are already used
We must let x=5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
If this line is given to have a slope of 3/2, let us at least put it in standard form, substituting the point ( 7, 4 ) into the equation afterwards:
y = 3/2* x + b, provided b ⇒ y - intercept,
( 4 ) = 3/2 * ( 7 ) + b,
4 = 21/2 + b,
b = 4 - 10.5,
b = -6.5
Equation: y = 3/2x - 6 1/2, or y = 1.5 - 6.5
$200 - $88 = $112
$112 / 32 weeks = $3.50
Brooklyn saved $3.50 each week
