Answer:

Step-by-step explanation:

2 qt + 1 cup = 72 oz

6 oz x 10 = 60 oz

72 oz - 60 oz = 12 oz = 1 cup and 4 oz

1/6*6 is 1, so we can say that 3*6 is 18.
So, the part will be 18 inches in real life.

(−t 4 −5t 3 −10t 2 )+(9t 3 +3t 2 −1)

klemol [59]

Answer:

$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

Step-by-step explanation:

Given the expression

$\left(-t^4\:-5t^3\:-10t^2\:\right)+\left(9t^3\:+3t^2\:-1\right)$

Remove parentheses: (a)=a

$=-t^4-5t^3-10t^2+9t^3+3t^2-1$

Group like terms

$=-t^4-5t^3+9t^3-10t^2+3t^2-1$

Add similar elements

$=-t^4-5t^3+9t^3-7t^2-1$ ∵ $-10t^2+3t^2=-7t^2$

Add similar elements

$=-t^4+4t^3-7t^2-1$ ∵ $-5t^3+9t^3=4t^3$

Thus, the equivalent expression in simplified form:

$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

How do you put f(8)=-1,f(6)=0 into point slop form?

Mademuasel [1]

Answer:

y + 1 = -1/2(x - 8)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Left to Right

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Step-by-step explanation:

Step 1: Define

f(8) = -1 → Coordinate (8, -1)

f(6) = 0 → Coordinate (6, 0)

Step 2: Find slope m

Substitute [SF]: $m=\frac{0+1}{6-8}$
Add/Subtract: $m=\frac{1}{-2}$
Simplify: $m=\frac{-1}{2}$

Step 3: Write Function

Substitute into general form.

Point 1: y + 1 = -1/2(x - 8)
Point 2: y = -1/2(x - 6)
