Let x be the digit in the tens place and y be the digit in the ones place.
so, the digit is xy
<span>
The ten's digit of a two digit number is 1 more than 4 times the units' digit.
</span>x = 4y + 1
<span>63 is subtracted from the number, the order of the digits is reversed
</span>10x + y - 63 = 10y + x
9x - 9y = 63
x = 4y + 1 ------------ (1)
9x - 9y = 63 ---------- (2)
Sub (1) into (2)
9(4y + 1) - 9y = 63
36y + 9 - 9y = 63
27y = 63 - 9
27y = 54
y = 2 ------- sub into (1)
x = 4(2) + 1 = 9
x = 9, y = 2
The number is 92
I think it is 3333% #I guessed
Answer:
f(x) = 4/9
Step-by-step explanation:
Multiply 4 by 1/3 squared and you have your answer.
Answer:
perpendicular slope= 1/4
Step-by-step explanation:
you have to make the equation equal to y so that would be -4x+3=y
and then you just find the negative reciprocal of the slope -4 which would be 1/4
