Answer:

m = n = 5√2

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you ...

Sin = Opposite/Hypotenuse

sin(45°) = m/10

m = 10·sin(45°) = 10·(√2)/2 = 5√2

The triangle is isosceles, so m = n.

n = m = 5√2

_____

The side ratios of an isosceles right triangle are 1 : 1 : √2. That is, the legs are 10/√2 = 5√2 in this triangle. It can be useful to remember these ratios for this "special" triangle.

Answers

Answer: -1

Step-by-step explanation: ANSWER : -1

f(x)=3x−1=y

⇒x=3y+1

∴f−1(y)=3y+1

⇒f−1(x)=3x+1

g(x)=5x+6=z

⇒x=5z−6

g−1(z)=5z−6

⇒g−1(x)=5x−6

g−1(f−1(x))=g−1(3x+1)

=53x+1−6

=15x−17

The second store charenly a $0.99 fee to use the photo machine, but the additional cost per photo is $0.35 After comparing the two stores, I realize my overall cost will be the same at each store. What is the value of x, the number of photos I need to print?

Answer:

x=28

Step-by-step explanation:

3.79+0.25x=0.99+0.35

-0.35x -0.35x

3.79+-0.10x=0.99

-3.79 -3.79

Find the value of x

Answers

Step-by-step explanation:

Given Angle AOC = 90,

Angle AOB + Angle BOC = 90

[tex]3x + 46 + 14 = 90 \\ 3x + 60 = 90 \\ 3x = 90 - 60 \\ 3x = 30 \\ x = 30 \div 3 \\ = 10[/tex]

Answer:

B) 10

Step-by-step explanation:

It is given that the (m<AOC) is (90) degrees. It is also given that (<AOB) and (<BOC) compose (<AOC). Therefore, the following statement can be made;

(m<AOB) + (m<BOC) = (m<AOC)

Substitute,

(3x + 46) + (14) = (90)

Simplify,

3x + 60 = 90

Inverse operations,

3x + 60 = 90

-60 -60

3x = 30

Step-by-step explanation:

how many solutions is there to the system of equations? 2x + 3y = 11 -4x - 6y = -22

Answers

Answer:

x = 4, y = -3

Step-by-step explanation:

{2x - y = 11

{x + 3y = -5

You can use the substitution method by solving for x in the second equation:

x + 3y = -5

Subtract 3y from both sides:

x = -3y - 5

Now, substitute this value for x into the first equation:

2x - y = 11

2(-3y - 5) - y = 11

Distribute:

-6y - 10 - y = 11

Add 10 to both sides:

-6y - y = 21

Combine like terms:

-7y = 21

Divide both sides by -7:

y = -3

Next, substitute this value for x into the second equation:

x + 3y = -5

x + 3(-3) = -5

Multiply:

x - 9 = -5

Add 9 to both sides:

x = 4

Please help I asked this question earlier and nobody answered! :(

Answers

Answer:

Step-by-step explanation:

One way to tell is to put both equations into slope-intercept form. That form is usually written [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.

Solve the first equation for y.

[tex]6x+2y=5 \\ 2y=-6x+5 \\ y=-3x+5/2[/tex]

The slope of this line is -3, and its y-intercept is 5/2.

Solve the second equation for y.

[tex]y+3x=2\\y=-3x+2[/tex]

The slope of this line is -3 and its y-intercept is 2.

The lines are parallel because they have the same slope and different y-intercepts. There is no solution to the system.
