Because any number multiplied by 1 is itself...1 X n = n, you could restate this function as f(n)=2(n-1). Therefore f(0)=2-1=1/2=.5. f(1)=20=1 f(2)=21=2 etc.

Which equation has roots of -3 and 5 (answer)

If the roots are -3 and 5 Then the formula is (x-3)(x+5)=0 or x2+2x-15=0

-3x +5y =44x+5y=32 (answer)

The way to solve this is to solve one of the equations for x or y. The bottom one looks easier. x=32-5y Substitute that value into the top equation. -3(32-5y)+5y=44 -96+15y+5y=44 20y=140 y=7 Now substitute y into the bottom equation x+5(7)=32 x+35=32 x=-3 Now...

The first thing to notice about this problem is that you have a mixture of Metric and English units. The first thing that I would recommend is to convert 410 miles into Kilometers 1 mile = 1.61 km 410 miles = (410*1.61) = 660 km (rounded to the nearest km) Now you need to...

(8,-10);y= 3/4x+1 (answer)

We need a line that is parallel to y=3/4x+1 that goes through (8,-10). The formula for a line is y=mx+b Since it is parallel to the given line we already know the slope or m is 3/4, we know the x is 8 and y is -10, we just need to find the y-intercept or b. We can also...

Let's say that you have 20 apples, but you can't find anyone who wants them. Mathematically, the answer would 20/0. Dividing by zero is like saying that no one cares about the thing you are trying to divide. If no one cares, why bother?

This is telling you that a line that cross the coordinates (5,y) and (7,-9) has a slope of -4. To compute the slope, we use the formula rise over run. The rise is (y -(-9)) and the run is (5-7). Therefore, the slope formula is (y-(-9))/(5-7)=-4. Now we solve for y. 1. ...
