Answer: 4
Step-by-step explanation:
4x - y = -4
add 4 to both sides
4x - y + 4 = 0
add y to both sides
4x + 4 = y
Answer:
3(x^y(5x^2y-x³)+25x⁴))
Step-by-step explanation:
15x^2y²-3x^3y+75x⁴
From 15x^2y²-3x^3y only, 3x^y is the common factor
=> 3x^y(5x^2y-x³)+75x⁴
Taking the common factor of the latter expression, 3 shows to be the common factor of all the expression.
=> 3(x^y(5x^2y-x³)+25x⁴)

Step-by-step explanation:
John get paid in a week in which he makes 48 toy cars = $312
<u>Step-by-step explanation</u>:
Step 1 :
- Pay for each first 40 toy cars = $6
- Pay for each additional toy car = increase in 50% of $6
Step 2 :
50% of $6 = (50/100)$6 = $3
Pay for each additional toy car = (50% of $6) + $6
= $3 + $6 = $9
Step 3 :
Pay for total of 48 cars = pay for 1st 40 cars + pay for additional 8 cars
= $6(40) + $9(8)
= $240 + $72
Pay for total of 48 cars = $312
