Simple...
you have: (-2,20) and (3,-10,)
Using

to find slope--->>>

=-6
m=-6
Using y=mx+b to find the equation of the line-->>>(Use any of the coordinates)
(-2,20)
20=-6(-2)+b
20=12+b
20=12+b
-12 -12
8=b
y=-6x+8
Thus, your answer.
(-2,7) and (14,21)
Find the slope by using the formula

Plug in the numbers.

Write it in point slope form first
y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
+ 7 +7
y = 7/8x + 8.75
Our final equation would be: <span>
y = 7/8x + 8.75</span>
Answer + Step-by-step explanation:
1) D be the symmetric of B with respect to C then CD = BC
A the symmetric of C with respect to B then AB = BC
We obtain :
CD = BC
AB = BC
Then AB = CD
2) m∠SBA = 180 - SBC = 180 - SCB = m∠SCD
3) we have :
BA = CD
BS = CS
m∠SBA = m∠SCD
Then
the triangles SBA and SCD are congruent
4)
the triangles SBA and SCD are congruent Then SA = SD
Therefore SAD is an isosceles triangle.
Answer:
660
Step-by-step explanation:
66 hundreds is 6600 so divided by 10 it's 660
Answer:
Philip, after 12 seconds, is 13.44 meters farther ahead after 12 seconds
Step-by-step explanation:
Philip
6.59 x 12 = 79.08
Mary
5.47 x 12 = 65.64
79.08 - 65.64 = 13.44
