Answer:

y=13+3x

Step-by-step explanation:

If this is the only equation given, you would want to isolate the y by itself.

y - 3x = 13

+3x +3x

Add the 3x because you are doing the opposite operation.

y=13+3x

12. Use a trigonometric ratio to find the measure of O in the triangle below. Give your answer to the nearest degree.

larisa [96]

Given :-

A right angled triangle with two sides 10cm and 9cm .

To Find :-

The value of theta .

Solution :-

At angle theta , 9cm side will be considered as the perpendicular and 10cm side will be hypotenuse . So , as we know that ;

$\longrightarrow sin\theta =\dfrac{perpendicular}{hypotenuse}$

Substituting the respective values,

$\longrightarrow sin\theta =\dfrac{9cm}{10cm}$

Simplify,

$\longrightarrow sin\theta= 0.9$

Take arcsin both sides ,

$\longrightarrow \theta =sin^{-1}(0.9)$

$\\\longrightarrow\underline{\underline{\theta = 64.15^o }}$

Hence the required answer is 64.15° .

What is the ratio 16 to 40 written as a fraction in lowest terms? plz help 50 points

Luda [366]

Answer:- $\frac{2}{5}$

Step-by-step explanation:

The given ration is 16 :40

In fraction, the above ratio can be written as : $\frac{16}{40}$

To write the above fraction in lowest terms, we need to divide the numerator and the denominator by the greatest common divisor.

Since, $16=2\times8\\40=5\times8$ , Hence, 8 is the greatest common divisor of 16 and 40.

Now, divide the numerator and denominator by 8, we get

$\frac{16}{40}=\frac{2}{5}$

12. Write the equation of the line passing through the point (2,6) with slope 4 in

stepladder [879]

Answer:

y = 4x - 2

Step-by-step explanation:

slope = 4

y -6 = 4 ( x- 2 )

distribute the 4 to ( x - 2 )

y - 6 = 4x - 8

add 6 to both side

y = 4x - 2

Hopefully this helps you understand this concept.
