O to A = (-8,2)(0,0) = (0 - (-8) / (0 - 2) = -8/2 = -4
A to B = (-12,3)(-8,2) = (2 - 3) / (-8 - (-12) = -1/4
so O to A is 4 times the slope of A to B
=====================
initial value is the y int....5
====================
(0,200)(1,160)
slope = (160 - 200) / (1 - 0) = - 40
u have a y int of 200
ur equation is : y = -40x + 200
==================
(0,25)(1,40)
slope = (40 - 25) / (1 - 0) = 15
y = mx + b
slope(m) = 15
(0,25)...x = 0 and y = 25
sub and find b
25 = 15(0) + b
25 = b <=== this is ur fixed amount
Answer:
16h^2-4h-42
Step-by-step explanation:
4h times 4h is 16h^2
4h times -7 is -28h
4h times 6 is 24h
6 times -7 is -42
Combine like terms to get 16h^2-4h-42
C. Revising because it should be your last stage in the writing process before you publish
a. <FEB and <AEB are alternate interior angles
b. AC and DG are parallel lines
c. EB and BF are the transversals
d. <ABE and <FEB are alternate interior angles, meaning that their angle measures are congruent, thus <ABE = <FEB = 45
e. <GFB and <ABF are alternate interior angles, meaning that their angle measures are congruent, therefore <ABF = 110
f. <GFB is a remote angle to triangle EBF. Remote angles are formed when one extends one of the sides of a triangle, the remote angle is found between the extension of the side and a side of the triangle. The remote angles theorem states that the sum of the two non-adjacent angles equals the remote angle. Applying this here one can state the following,
<FEB + <FBE = <GFB
45 + <FBE = 110
<FBE = 65
f. <FBC and <GFB are same-side interior angles, this means that the two angles are supplementary, their angle measures add up to 180. Apply this property here,
<GFB + <FBC = 180
110 + <FBC = 180
<FBC = 70
