Answer:
2
Step-by-step explanation:
The equation for this line is y=2x+1
The slope of the line is 2 because it moves 2 up on the y scale after it moves 1 on the x scale.
^ means to the power of or exponent
logb(x) = y is b^y = x
(2x+y2)5 = 32x5 + 160x4y + 320x3y2 + 320x2y3 + 160xy4 + 32y5
<u>Answer:</u>
20
<u>Step-by-step explanation:</u>
We know that the difference between a hundred and a number is four times that number.
So assuming the number to be x, we can write the difference between a hundred and a number as <em>100 - x </em>and four times that number as <em>4x</em>.
So by combining these together, we get:
100 - x = 4x
100 = 5x
x = 100/5
x = 20
Therefore, the unknown number is 20.
