Answer:

Step-by-step explanation:

3(-2x+3)>12

<=> -2x +3 >12/3

<=> -2x > 12/3 -3

<=> -2x > 1

A line passes through the points(-9,9) and has a slope of 2/3

Anni [7]

ANSWER

y = 2/3x + 15

Explanation:

Equation used: y - y1 = m( x - x1 )

y - 9 = 2/3 ( x - -9 )

y - 9 = 2/3x + 6 ( distribution )

y - 9 = 2/3x + 6 ( add 9 to 6 )

y = 2/3x + 15

If the average of 5 consecutive whole numbers is 12, what is the largest number?

REY [17]

When I think about average with consecutive numbers, I think that it’s also the median. Let’s check.
If 12 is the median, there’s two numbers that are less than it and two that are more.
The list would be:
10, 11, 12, 13, 14
Let’s check to see if the average is 12. To find average, you have to add all the numbers together and then divide that number by the quantity of numbers in the list.
10+11+12+13+14=60
Now divide it by 5.
60/5=12
So, the largest number is 14.

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AH=4 and HC=1, find BH.

faltersainse [42]

Answer:

$BH=2$

Step-by-step explanation:

Please find the attachment.

We have been given that triangle ABC is a right triangle, having a right angle at point B and BH is the altitude.

We can see from our attachment that the altitude BH is drawn to hypotenuse AC.

Altitude geometric mean theorem states that the altitude from the right angle to the hypotenuse divides the hypotenuse into two segments. Each leg of the right triangle is the mean proportional of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

Using the above theorem we can set proportions for our given side lengths as:

$\frac{\text{Left}}{\text{Altitude}}=\frac{\text{Altitude}}{\text{Right}}$
