Write an equation that represents the line

Dafna11 [192]

Answer:

y = -4/3x -1

Step-by-step explanation:

y = slopex + y-int

We can find the slope -4/3 by going down 4 times to the level of the second point from the first point. Then we go to the right 3 times to get to the 2nd point.

y = -4/3x + b

The spot on the line where x is 0 will be the y-intercept

In this case it is -1

y = -4/3x - 1

What calculation can be used to find the value of p in the equation p^3 =8

blsea [12.9K]

Cube Root

${p}^{3} = 8 \\ p = \sqrt[3]{8} \\ p = \sqrt[3]{ 2\times 2 \times 2} \\ p = 2$

Formula

${p}^{3} - 8 = 0$

Use the following formula.

${x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )$

$(p - 2)( {p}^{2} + 2p + 4)$

The expression p²+2p+4 has the discriminant less than 0 ( D < 0 ).

Thus, remove the expression and leave only p-2

$p - 2 = 0 \\ p = 2$

Substitution

The most obvious number that multiplies itself three times and equal 8 is 2.

Substitute p = 2

${p}^{3} = 8 \\ {2}^{3} = 8 \\ 2 \times 2 \times 2 = 8 \\ 8 = 8$

The equation is true, thus 2 is the answer.

guajiro [1.7K]

Answer:

The given statement is true.

Step-by-step explanation:

In order to inscribe a circle in a triangle, the circle's center must be placed at the incenter of the triangle.

This statement is true.

The INCENTER is the center of the circle that is inscribed in the triangle. Like the centroid, the incenter is always inside the triangle.

The volume of dry goods like apple or peaches can be measured using bushels, pecks and quarts. A bushel contains 4 pecks and a p

Lisa [10]

Answer: $q= 32b$

Step-by-step explanation:

Given: A bushel contains 4 pecks and a peck contains 8 quarts.

i.e. A bush = 4 pecks

A peck = 8 quarts

Then, Number of quarts in 1 bush = 4 (8) =32

Let b = number of bushes and q = number of quarts

Number of quarts(q) in b bushes = 32b

hence, required equation: $q= 32b$ which describes the relationship between the number of b bushels and the number of q quarts.
