A=1/2 bh
40=1/2•20h
80=20h
4=h
The answer is a . because i said so .
Answer:
I dont know all of them but this might help some. Im on this subject to
With this information we know that in slope-intercept form that the equation will at least look like this.
y= -2x + b.
But we have to look for b. In order to do this we are going to have to plug in (5,3) into the x and y values.
3= -2(5) + b
3= (-10) + b
13= b
We then put this b value into the slope intercept formula.
y= -2x + 13 < this is your final answer
Assume x > 0 then (-x)^(1/2) = sqrt(-x) and we cant take sqaure roots of negative numbers.............yet
so (-3)^(1/4) is<span><span>−3</span><span>−−−</span>√4</span>which is not ok but<span><span>−3</span><span>−−−</span>√3</span>is fine
