180, because 9 and 20 don’t have any common multiple (both numbers couldn’t be simplified)

Answer:

y=3x+2

Step-by-step explanation:

For a the equation is y=3x+2 because he makes 3 every hour (3x) and he already has 2 (+2).

For the graph you replace x with any number and solve. Plot the point.

Then you do it again but with a different x.

Finally you draw a straight line trough the 2 points.

Choose the graph below that has an undefined slope.

Ronch [10]

Answer:

The correct option is A.

Step-by-step explanation:

The first line passing through the points (-6,2) and (-6,0).

The slope of a line is

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of first line is

$m_1=\frac{0-2}{-6-(-6)}=\infty$

The second line passing through the points (0,-4) and (-1,1). The slope of second line is

$m_2=\frac{1-(-4)}{-1-0}=-5$

The third line passing through the points (0,-6) and (2,-6). The slope of third line is

$m_3=\frac{-6-(-6)}{2-0}=0$

The fourth line passing through the points (0,6) and (-3,-7). The slope of fourth line is

$m_4=\frac{-7-6}{-3-0}=\frac{13}{3}$

Since the slope of a vertical line is infinity, Therefore option A is correct.

How do you calculate angles on a straight line??

dimaraw [331]

Answer:

Step-by-step explanation:

Straight line is an angle whose vertex point(O) has a value of 180. The arms (OA & OB) of the straight line angle lies opposite to each other from the vertex point

Sum of all the angles in a straight line = 180

From this you can find the value of unknown angle, if other angles are given.

∠AOC + ∠BOC = 180

Which equation can be used to find the measure of angle BAC? A.) inverse tan (5/12) B.) inverse cos (5/13) C.) inverse sin (12/5

finlep [7]

Answer:

Step-by-step explanation:

The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.

Select the correct choice that completes the sentence below.

vodomira [7]

$\sf \red⇛ \green {3a + 1 = 16}$

Move the constant to the right-hand side and change its sign to minus sign since it is in plus

$\sf \red⇛ \green{3a = 16 - 1}$

Subtract the numbers

$\sf\red ⇛ \green{3a = 15}$

Divide both sides of equation by 3

$\sf \red⇛ \green{a = 5}$

On observing the above steps, Option B is correct!
First step is subtraction then division
