Answer:

y=3 and x=0

Step-by-step explanation:

3x−3y=−9. i'm going to solve for x.

3x−3y+3y=−9+3y

3x=3y−9

3x/3=(3y-9)/3  to isolate x we have to divide everything by 3

x=y−3

so now that we have x we can substitute it in 4x+4y=12

4(y-3)+4y=12

4y-12+4y=12

8y-12=12

8y-12+12=12+12

8y=24

8y/8=24/8

y=3

we have y which equals 3, so now we can substitute it into any equation so solve for x again.

3x – 3y = -9

3x-3(3)=-9

3x-9=-9

3x-9+9=-9+9

3x=0

3x/3=0/3

x=0

so, final answers are y=3 and x=0

checking our work:

3(0)-3(3)=-9

0-9=-9

-9=-9 true

4(0)+4(3)=12

0+12=12

12=12 true

hope you got your answer! :)

===================================================

Work Shown:

The uppercase letters A,B,C are the angles, while the lowercase counterparts (a,b,c) are the sides opposite those angles. For instance, side b is opposite angle B.

We have this known info:

The ultimate goal is to find side BC, which is opposite angle A. So this is side a.

Now apply the law of sines to solve for 'a'.

sin(A)/a = sin(C)/c

sin(59)/a = sin(15)/10

10*sin(59) = a*sin(15)

a*sin(15) = 10*sin(59)

a = 10*sin(59)/sin(15)

a = 33.1184013279463

Make sure your calculator is in degree mode.

This rounds to the nearest tenth to get a = 33.1 which is the approximate length of side BC.

Answer:

-8w=16

Step-by-step explanation:

-5w-9+9 = 3w+7+9

-5w=3w+16

-5w-3w=3w-3w+16

-8w=16

To solve:

-8w/-8=16/-8

w = -2

Answer: =4x+18

Step-by-step explanation:

Let's simplify step-by-step.

4x−7+25

=4x+−7+25

Combine Like Terms:

=4x+−7+25

=(4x)+(−7+25)

=4x+18

Answer:

=4x+18

Answer:

5×4+9

Step-by-step explanation:

The product of something means to multiply, so you would multiply 5 and 4 together.

Then you would add 9 to that.

Answer:

f(-3)=(-3)²-2(-3)=9--6=9+6=15

Answer:

15

Step-by-step explanation:

f(x)=x^2-2x

f(-3)=(-3)^2-2(-3)

f(-3)=9+6

f(-3)=15

Answer:

Step-by-step explanation:

volume of 154×100×84 box = 1,293,600 cm³

dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80

volume of airspace = 150×96×80 = 1,152,000 cm³

volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³

Answer:

Sydney is 21 years old

Step-by-step explanation:

1. subtract 11 from 53 (53-11=42)

2. divide the difference by 2 (42/2=21)

Answer:

x+11+x=53

2x+11=53

-11. -11

2x=42

x=21

Sydney is 21 years old

Devaughn is 32 years old

This is a summation notation also called the sigma notation.

In this case it means starting with k=0 what's the sum of (1+k!) for all integer k until 4

So we just need to find the sum 1+0!+1+1!+1+2!+1+3!+1+4!=5+1+2+6+24=8+30=38

Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.

Answer:

y-2x=8 (label equation 1)

16+4x=2y (label equation 2)

divide equation 2 by 2 to find y

y=2x+8

sub this in equation 1

(2x+8)-2x=8

2x+8-2x=8

8=8

once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

Answer:

y : x: = 5 : 4

Step-by-step explanation:

x to y = 4 to 5

Rewrite;

x:y = 4:5

Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;

x : y= 4 : 5

5x = 4y

Inverse operations;

5x = 4y

x = [tex]\frac{4}{5}[/tex]y

Now substitute this into the equation y:x

y : [tex]\frac{4}{5}[/tex]y

Rewrite as a fraction;

[tex]\frac{y}{\frac{5}{4}y}[/tex]

Simplify;

[tex]\frac{1}{\frac{4}{5}}\\\\\frac{5}{4}[/tex]

Rewrite as a ratio;

y : x = 5 : 4

Slope intercept form is y = mx + b

Answer:

B, an = 4n - 9

Step-by-step explanation:

The sequence is for every time the exponent on a goes up one, the number that it equals to goes up by 4. So to find the nth term, we at 4 to n. I hope this helped! :)

not imp u say this is triangle rect from the pythagore theorie then u say in a tr rec the angles other than the 90 degree one is 45 degrees

If you want to know what's the value of x in 2 functions, you need to do a single variable equations.
