1. combining like terms you should get: -5x^4+5x^3-4x^2+17x-1
2. again combine all like terms to get: 15x^4+x^3+2x^2+15x+1
3. 5x^9+3x^8-x^7+16x^6+10x^5+x^4-5x^3+33x^2-16x
Answer:
2.33 pounds of candy altogether
Step-by-step explanation:
He has 1/6 in each bag and there are 14 bags so,
1/6 * 14 = 2.333
he has 2.33 pounds of candy altogether
Answer:
x = 6 ,,, 5/9x + 2/3 = 4
Step-by-step explanation:
5x - 8 = 22
5x = 22 + 8
5x = 30
x = 30/5
x = 6
5/9 * 6 + 2/3 =
30/9 + 2/3 =
30/9 + 6/9 =
36/9 =
4
Answer:
y = 5/4 (x) + 7
Explanation:
Slope of a line (m): (y₂ - y₁) ÷ (x₂ - x₁)
Slope: (2 - -3) ÷ (-4 - -8) = 5 ÷ 4 = 5/4
Point slope form: y - y₁ = m (x - x₁)
Equation: y - 2 = 5/4 (x - -4)
distribute the 5/4
y - 2 = 5/4 (x) + 5
add 2 to both sides
y = 5/4 (x) + 7
I hope this helps!
