Use distributive property: a(b +/- c) = ab +/ ac.

(x - 9)(x + 2) = (x)(x) + (x)(2) - (9)(x) - (9)(2) = x² + 2x - 9x - 18

= x² -7x -18

The points (–8, –4) and (6, 10) fall on a particular line. What is its equation in slope-intercept form?
elena55 [62]
First we need to use two point to find the slope (m)

m=(y2-y1)/(x2-x1)
X1=-8
Y1=-4
X2=6
Y2=10

m=(10-(-4))/(6-(-8))
m=(10+4)/(6+8)
m=14/14
m=1

Eq of the line formula :
Y-y1=m(x-x1)
Y-(-4)=1(x-(-8))
Y+4=x+8
Y=x+4

After 10 months the simple interest earned annually on an investment of $6000 was $769. Find the interest rate to the nearest te
Lady bird [3.3K]
Simple interest = $769
Principal = $6000
Rate = ?
Time = 10 months (must convert to years if in months) = 10/12 = 0.833
Formula
I = prt
Substitute
769 = 6000 × r × 0.833
769 = 4998r
Divide both sides by 4998
769/4998 = 4998r/4998
0.15386 = r
(to the nearest tenth of a percent) = 0.15
Therefore, your rate is 0.15%.

zaharov [31]
5.55% = 1/18

So, cut the cake into 18 equal squares.

The cake is twice as long as it is wide, so that means cut half the cake (6 3/4 x 6 3/4) into 9 pieces, each with a side of 1/3 * 6 3/4 = 2 1/4 inches.
