Answer: the answer is 2/5

The equation of lines x - 3y = 15 and y = -3x + 4 are perpendicular lines since the product of their slopes is -1

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line A be represented as

x - 3y = 15

Adding 3y on both sides of the equation , we get

3y + 15 = x

Subtracting 15 on both sides of the equation , we get

3y = x - 15

Divide by 3 on both sides of the equation , we get

y = ( 1/3 )x - 5   be equation (1)

Now , it is of the form y = mx + b where m is the slope and b is the y-intercept

So , slope of line A = 1/3

And ,

The equation of line B is y = -3x + 4

Now , it is of the form y = mx + b where m is the slope and b is the y-intercept

So , slope of line B = -3

Now , the product of the slopes = -1 , means the lines are perpendicular

So , ( 1/3 ) x -3 = -1

-1 = -1

Hence , the lines are perpendicular

You can use the following steps to calculate probability, and this can work for many applications that fall under a probability format:

1. Determine a single event with a single outcome

2. Identify the total number of outcomes that can occur

3. Divide the number of events by the number of possible outcomes

Step-by-step explanation:

m<4. 180°-46°= 134°

m<2. 134°

Answer: 128 degrees

Step-by-step explanation:

If m1 = 27° and m2 = 25°, what is m3?

27+25=52

180-52=128

that's the simplest way to do it

The measure of m₃ will be;

⇒ m₃ = 128°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In a triangle;

⇒ m₁ = 27°

⇒ m₂ = 25°

Now,

We know that;

In a triangle, The sum of all interior angle is equal to 180°

Hence, We get;

⇒ m₁ + m₂ + m₃ = 180°

⇒ 27° + 25° + m₃ = 180°

⇒ m₃ = 180 - 52°

⇒ m₃ = 128°

Thus, We get;

⇒ m₃ = 128°

Choice C. is equivalent.

Let's first simplify, starting with the denominator.

a to the power of 0 is 1. —> any value to the power of 0 is 1.

That leaves us with (1b^2)^4. Now we can distribute the exponent. But before that, let's get rid of the coefficient 1, which isn't necessary.

Now we are left with (b^2)^4.

Let's use the power of the power rule, which means that we multiply the exponent by the exponent. The denominator is now b^8.

Looking at the numerator, there is a b, which has a hidden exponent of one. —> We can get rid of it by taking away its exponent of 1 with the b^8 from the denomiator.

. . . b^1 goes away, and b^8 becomes b^7.

We cannot simplify any further, therefore the final expression is. . .

Answer:

∠AMC = 76°

Step-by-step explanation:

1) Because ∠YMC = 170°, you need to add 5x+19 (∠YMA) and 5x+1 (∠AMC) to equal the length of ∠YMC:

170 = 5x + 19 + 5x + 1

2) Combine like terms:

170 = 10x + 20

3) Subtract 20 from both sides:

150 = 10x

4) Divide by 10:

x =15

5) Replace x in ∠AMC with 15:

5(15) + 1

6) Multiply:

∠AMC = 76°

The measure of ∠AMC is 76°.

Given that, m∠YMC=170°, m∠YMA=(5x+19)° and m∠AMC=(5x+1)°.

We need to find the value of m∠AMC.

The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be complementary angles or supplementary angles when they share the common vertex and side.

Now, m∠YMA+m∠AMC=m∠YMC

⇒(5x+19)° + (5x+1)°=170°

⇒10x+20=170

⇒10x=150

⇒x=15

So, m∠AMC=5x+1=76°

Therefore, the measure of ∠AMC is 76°.

Hope this helps and can you please mark me brainliest? I just need 4 more brainliest to become expert

Answer:

$11

Step-by-step explanation:

So in order to calculate the amount of money each book cost, we want to first find the exact number all 8 books cost. We know that Dan has 17 dollars left from the total 105 so we should subtract 17 from 105 to find out the total cost:

$105 - $17 = $88

Now we can divide the total cost by 8 because we want to find the unit price or the price of 1 book:

$88 / 8 = $11

From the equation above, we found out that the unit price is $11. :)

Answer:

Step-by-step explanation:

I hope this helps!

Answer:

The value of 'g' in the equation is -1.22.

Step-by-step explanation:

Solving this problem entails of isolating the variable 'g.'  To start this process, we must use the subtraction property of equality. We will subtract 1.3 from both sides of the equation.

1.3 - 5g = 7.4

1.3 - 1.3 - 5g = 7.4 - 1.3

-5g = 6.1

You can see that we have gotten one step closer to getting the variable alone. Now we will use the division property of equality. To do this, divide both sides of the equation by negative five.

-5g = 6.1

-5g / -5 = 6.1 / -5

g = -1.22

The variable has finally been isolated. The value of 'g' is -1.22.
