Answer:
4
Step-by-step explanation:
5 times 12 plus unknown is 80 so 80 divided by 5 is the sum of 12 + unknown number. So 80 divided by 5 is 16. 12 plus unknown is 16 so the unknown number is 4.
Given ΔABC with A(-6, -1), B(3, 7), and C(4, -6)
Since it is an altitude and pass thru B, t
hen it is perpendicular to AC.
so slope(AC) = (-1 +6)/(-6 - 4) = -5/10 = -1/2
perpendicular lines, slope is opposite and reciprocal so slope = 2
passes through B(3, 7)
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1
equation in slope intercept form:
y = 2x + 1
You would make two mountains because you need to compare the two factor mountains
P(.25)-P= new price. Explained: multiply the price it already is by .25(25% as a decimal) then subtract it from the original price and that should give you the discounted price
It's equal to the exponent, 2 to what power = x^3 y^5
