Answer:
12
Step-by-step explanation:
#4
(-2,4)(-3,5)
slope = (5-4)/(-3+2) = 1/-1 = -1
point slope form
<span>y-y1 = m(x - x1)
</span>y - 4 = -(x + 2)
#5
y intercept of 3 , y = 3 or (0,3)
x intercept of -2 , x = - 2 or (-2,0)
slope = -3/2
slope intercept form
y = mx + b
y = -3/2x + 3
#6
point slope form
y = 1/2x - 4 passing thru(5,2)
y - 2 = 1/2 (x - 5)
# 7
y = 1/2x - 4
perpendicular slope = -2
passing thru (-1,4)
using point slope form
y-4 = -2(x+1)
Answer:
6983/1000 OR 6.983
Step-by-step explanation:
6*1=6
9*1/10=9/10
8*1/100=8/100
3*1/1000=3/1000
6+9/10+8/100+3/1000=6983/1000
OR
6.983
Answer:
Step-by-step explanation:
Given
← factorise numerator and denominator
2x² - 18 ( factor out 2 from each term )
= 2(x² - 9) ← difference of 2 squares
= 2(x - 3)(x + 3)
and
x² + 4x - 21 = (x + 7)(x - 3) , then
= 
← cancel common factor (x - 3) on numerator/ denominator
=
