Answer:

y=-3(x-9)

Step-by-step explanation:

Point slope form is y-y1=m(x-x1)

x1=9

y1=0

m=-3

plug it all in!

y-0=-3(x-9)

y=-3(x-9)

Hope this helps!

Find the length of a picture frame whose width is 3 inches and whose proportions are the same as a 9-inch wide by 12-inch long p

barxatty [35]

Answer:

4 inches

Step-by-step explanation:

We can set up a proportion to find out the length value (assuming x is the length of the frame)

$\frac{3}{x} = \frac{9}{12}$

We multiply 12 and 3...

$12\cdot3=36$

And divide by 9...

$36\div9=4$

So, the length of the frame is 4 inches.

Hope this helped!

I need help with Q11 I’m not sure if I did the calculations right because the area seems way to high

liubo4ka [24]

Answer:

The are a is 6

The length of h = 2.4

Step-by-step explanation:

This is a 3 4 5 special triangle so the length of the hypotenuse is 5

The area for a triangle is calculated by multiplying height to the base and that divided by two

Since it's a right triangle we can take any side length as the height and the result wouldn't change

4×3÷2 = 6 is the area for this triangle now we can use thus information to find the length of h :

h × 5 ÷ 2 = 6

5h = 12

h = 2.4

Which mathematical symbol would best fill in the blank to compare the two real numbers?

Vikki [24]

Answer:

squareroot of 7 < 14/5

Step-by-step explanation:

We are given that two real numbers

squareroot of 7 and 14/5

We have to compare the given two real numbers and fill the mathematical symbol in the blank

In order to compare the given real number we will find the value of given real numbers .

Value of squareroot of 7 = 2.646

Value of 14/5 = 2.8

Value of 2.645 is less than 2.8.

Hence, squareroot of 7 is less than 14/5

hope i helped! :D
