K=slope
b=y intercept
find slope
slope=(y2-y1)/(x2-x1)
(x,y)
(1,-2)
(-2,-8)
x1=1
y1=-2
x2=-2
y2=-8
slope=(-8-(-2))/(-2-1)=(-6)/(-3)=2/1=2
k=2
subsitute
y=2x+b
subsitute one point
(1,-2)
x=1,y=-2
-2=2(1)+b
-2=2+b
subtract 2
-4=b
y=2x-4
Answer:
By SAS rule
Step-by-step explanation:
Required to Prove
ABC is congruent to DEC
Given
C is midpoint of AD and BE
As C is the midpoint of both line segments
AC=CD
BC=CE
and ∠ACB=∠DCE(Vertically opposite angles)
⇒By SAS(side-AC and DC, angle-∠ACB,∠DCE,side-BC and EC) congruency rule
triangle ABC is congruent to triangle DEC
Given:
Price of a pair of binoculars = $155.75
Sales tax = 6.5%
To find:
The amount of sales tax Nick will pay on the purchase to the nearest cent.
Solution:
According to the question,
Sales Tax value = 6.5% of Price of a pair of binoculars
Therefore, the amount of sales tax is $10.12.
Answer:
The height would be 14in.
Step-by-step explanation:
Do 10 1/2 divided by 3/4.
Work:
10 1/2 = 21/2
21/2 / 3/4
21/2 x 4/3 = 84/6
84/6 = 14
20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
