Hey there!

(0.4 + 1.6) × 6

= 2 × 6

≈ 2 + 2 + 2 + 2 + 2 + 2

≈ 4 + 4 + 4

≈ 8 + 4

≈ 12

Therefore, your answer is: 12

Good luck on your assignment & enjoy your day!

if you add four numbers together and then divide the sum by 4 you find the a.mean b. weighted average c. median d, mode

andreev551 [17]

The answer is a. mean. This is the same as the average. (The median is different. It is the number in the middle of all the numbers when they are arranged from smallest to largest. There is no summation or division required in order to determine it.)

2 1 point The point, (-3, 7), is on the line y = -3x+7. True O False

sladkih [1.3K]

Step-by-step explanation:

in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
Now let us plug in the value of x=-3
$y = - 3( - 3) + 7 \\ y = - 9 + 7 \\ y = - 2$
now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.

What are some relationships between sets of numbers??????

Olin [163]

Some sets of numbers are rational and irrational numbers.
Rational numbers are numbers you can make by dividing one integer by another.
Irrational numbers are numbers that can be written as a simple fraction.

Janine wants a necklace 45 beads long

seraphim [82]

If there are 45 beads, with a ratio of $1:4$
Then,
$\frac{45}{5}=9$
Then if $\frac{1}{4}=\frac{9}{x}$
Then $x=9*4$
Therefore, $x=36$
Meaning, there would be a ratio of 36 beads to 9 beads

What are the coordinates of the orthocenter of △JKL with vertices at J(−4, −1) , K(−4, 8) , and L(2, 8) ?

PilotLPTM [1.2K]

ANSWER

The orthocenter is $(-4,8)$

EXPLANATION

The orthocenter is the point of intersection of all the altitudes of a triangle.

If it is a right angle triangle then the orthocenter is the point at which the right angle is made.

If it is not a right angle triangle, then you have to find the equations of any two of the altitudes and solve simultaneously.

So you must first check to see if it is a right angle triangle that way you do not have to do bunch work.

The given triangle has vertices $J(-4,-1)$ , $(-4,8)$ , and $L(2,8)$ .

$Slope_{JK}=\frac{8--1}{-4--4}$

$Slope_{JK}=\frac{8+1}{-4+4}$

$Slope_{JK}=\frac{9}{0}$

Since the denominator is zero, the slope is undefined.

If the slope of a straight line is undefined, then that line is parallel to the y-axis. In other words, it is a vertical line.

$Slope_{JL}=\frac{8--1}{2--4}$

$Slope_{JL}=\frac{8+1}{2+4}$

$Slope_{JL}=\frac{9}{6}$

$Slope_{JL}=\frac{3}{2}$

$Slope_{KL}=\frac{8-8}{2--4}$

$Slope_{KL}=\frac{0}{2+4}$

$Slope_{KL}=\frac{0}{6}$

$Slope_{KL}=0$

if a straight line has a slope of zero, that line is parallel to the x-axis or it is horizontal.

From the slopes we can see that side KL of the triangle is horizontal and side JK is vertical. This two sides will meet at right angles at K.

See graph.

Therefore the coordinates of K, $(-4,8)$ is the orthocenter of the given triangle.
