Answer:

Your answer is indeed correct.   f(-8) = 3

Step-by-step explanation:

f(x) = -x^{2}  - 4x + 35\\f(-8) = -( -8)^{2} - 4(-8) + 35\\f(-8) = -64 + 32+ 35\\f(-8) = 3

What is Y=2(3x+6)(5x-4)
Sliva [168]

Answer:

y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

Step-by-step explanation:

Given: y=2(3x+6)(5x-4)

Use the distributive property!: y=(6x+12)(5x-4)

Use the distributive property!: y=(5x(6x+12)-4(6x+12))

Use the distributive property!: y=(30x^2+60x)-(24x+48)

Remove parenthesis: y=30x^2+60x-24x+48y=30x^2+36x+48 OR f(x)=30x^2+36x+48

This is an exponential function/exponential graph. Hope I helped!

Andrews [41]
Equilateral: "equal"-lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and we have two legs, right? Also iSOSceles has two equal "Sides" joined by an "Odd" side. Scalene: means "uneven" or "odd", so no equal sides.

Reptile [31]

Answer:

26,910 meters

Step-by-step explanation:

The glacier moves 29.9 meters a day.

In 100 days it will move 29.9(100)=2990 meters.

In 1000 days it will move 29.9(1000)=29900 meters.

29,900-2,990=26,910 meters
