(-3,5)(1,-15)
slope = (-15 - 5) / (1 - (-3) = -20/4 = -5
y = mx + b
slope(m) = -5
use either of ur points...(-3,5)...x = -3 and y = 5
now we sub and find b, the y int
5 = -5(-3) + b
5 = 15 + b
5 - 15 = b
-10 = b
so ur equation is : y = -5x - 10....or 5x + y = -10
Answer:
28
Step-by-step explanation:
-2+9 (4)=7(4)=28
-4.2/12 = -42/120 = -7/20
-2/7 / -8/21 = 3/4
We know that 1 ft = 12 in.
The dimensions of the trunk of a car:
4 ft = 48 in wide, 3 ft = 36 in deep, 2 ft = 24 in tall.
V = 48 * 36 * 24 = 41,472 in³
41,472 in³ ≈ 4 * 10^4 in³
And the volume of the calculator:
V ( calc. ) = 3 * 4 * 12 = 144 in³
Answer:
Desi`s error is D ) The volume of the calculator is not about 60 in³.
Step-by-step explanation:
f(x)=3x²-3x
f(-3)=3(-3)²-3(-3)
=3(9)+9
=27+9
=36
g(x)=5x-1
g(-7)=5(-7)-1
=-35-1
=-36
