Answer:

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (-8,9) and slope 5/4

The equation of the line is

$y - 9 = \frac{5}{4} (x + 8) \\ y - 9 = \frac{5}{4} x + 10 \\ y = \frac{5}{4} x + 10 + 9$

We have the final answer as

$y = \frac{5}{4} x + 19 \\$

A 14 foot is cut into two pieces so that one piece is 3 feet longer than twice the shorter piece

DochEvi [55]

To answer the question above, let x be the shorter one of the pieces. With the variable, we can express the longer piece as 2x + 3. Based on the given, the sum of the lengths of these pieces should sum up to 14 ft.

2x + 3 + x = 14 ft, x = 3 2/3 ft

Substituting this value for the longer piece, we get 10 1/3 ft. Thus, the lengths of the pieces are 3 2/3 ft and 10 1/3 ft.

A basketball player makes 60% of his free throws. We set him on the line of free-throw and informed him to shoot free throws unt

pshichka [43]

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

$P = 60\%$

Convert to decimal

$P = 0,6$

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

$p + q = 1$

$q = 1 - p$

Substitute 0.6 for p

$q = 1 - 0.6$

$q = 0.4$

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

$Probability = p^5 * q$

$Probability = 0.6^5 * 0.4$

$Probability = 0.031104$

Hence;

<em>Option B answers the question</em>

U(8, 9) and V(2, 5) are the endpoints of a line segment. What is the midpoint M of that line segment?

Pavel [41]

Answer:

The midpoint M is (5,7)

Step-by-step explanation:

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

U(8,9)

V(2,5)

m = [(8+2)/2 , (9+5)/2]

= [(10/2) , (14/2)]

= (5,7)
