£350 because 420/6 is 70 and 70*5 is 350
The answer to this question:
h=-12
Answer:
The one in the middle would be the quadratic function. I know this because of how when it gets to 10, it starts to repeat the other two numbers behind it.
Step-by-step explanation:
Answer: smaller: 18 ; larger: 20
Step-by-step explanation:
Let n be the smaller integer. Then the larger integer is n+2. So:
2n=n+2+16
n=18
The smaller integer is 18; the larger one is 20.
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)
7x-y=9
-3x+y=-5 (now add both equations)
7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)
x=1
y=3x-5=3×1-5=-2
y= -2
answer: x=1, y=-2
