It’s -3x+6 because if you subtract three off of six it’s going to be three so that is why 3X +6 is the answer

What is the graph of 3x + 5y = –15?

Liono4ka [1.6K]

Answer:

Graph is option A

Step-by-step explanation:

3x + 5y = –15

To graph the equation , we need to get y alone

$3x + 5y = –15$

Subtract 3x on both sides

$5y = -3x–15$

Divide whole equation by 5

$y=-\frac{3x}{5} -3$

To graph this equation , we need to make a table

Plug in some number for x and find out y

x $y=-\frac{3x}{5} -3$

0 -3

-5 0

Two points on the graph is (-5,0) and (0,-3)

Graph is option A

Right angle triangle problem solve for x

vladimir2022 [97]

Since the side labeled 3 is 1/3 of 9 it's safe to assume the angle opposite is 1/3 of 90 degrees, making it 30 degrees. Here we are gonna use sin. The formula is gonna be sin(30)=3/x which can be turned into x(sin(30))=3 then divide both sides by sin(30) getting x=6. For Y, you're going to do Pythagorean Theorem. First, take 6^2 and subtract 3^2 which is 25 then square root that to get 5 which is the height of the smaller triangle. Then Pythagorean theorem again, 5^2 plus 9^2 equals 106 square root that to get roughly 10.3. Getting you the answeres of X=6 and Y=10.3

3) Find the value of FD. bited F 12 12 13x - 16 E 4x+11 D

vlada-n [284]

The Length of FD = 26 cm

According to the given information

FE = FC = 12cm

As FE, FC both are radius of circle

The tangent segments to a circle from a external point are equal

Hence

CD = ED

13x - 16 = 4x + 11

13x - 4x = 11 + 16

9x = 27

x = 27/9

x = 3

CD = 13x - 16

= 13 × 3 - 16

= 23 cm

ED = 4x + 11

= 4 × 3 + 11

= 23 cm

In Triangle FED

FE is perpendicular to ED

According to Pythagoras Theorem

$FD^{2}= FE^{2}+ED^{2}$

= $12^{2}+ 23^{2}$

= 673

FD = 26 cm approx.

The Length of FD = 26 cm

Solve the problem. Make sure your answer is in simplest form and improper fractions are expressed as mixed numbers. A packer fil

postnew [5]

Easy! Just multiply 7 1/3 by 8 which leaves you with 58 2/3. Now, that 1/4 is 1/4 of an hour. If you can fill 7 1/3 boxes in 1 hour, how many can you fill in 1/4? 7 1/3 divided by 1/4 is 29 1/3. Add them together. 81 boxes.
