Contruct 3 equation starting with -2

olga_2 [115]

Answer:

1. -2, 2. -23, 3. 25

Step-by-step explanation:

1. -2+5x8/-12= step 1: add -2+5

-2+5=3 step 2: 3(8)

3x8= 24 step 3: 24/-12

24/-12= -2

2. -2(9-4)+3=? step 1: combine like terms -2(9) and -2(-4)

-18-8+3=? step 2: combine like terms

-26+3=? step 3: combine like terms

-23=?

3. 2x + 130=180 step 1: -130 on both sides

2x = 50 step 2: /2 on both sides

x = 25

Solve the system by graphing. Write the solution as an ordered pair. y = 1/3x + 2 y = –x – 2

Dima020 [189]

ANSWER

The solution is where the two graphs intersect, which is
$(-3,1).$

EXPLANATION

The given system of equations are
$y = \frac{1}{3} x + 2$
and

$y = - x - 2$

We need to graph the two equations.

Let us graph

$y = \frac{1}{3} x + 2$
first.

We need at least two points.

You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.

When
$x = 0$

$\Rightarrow \: y = \frac{1}{3} (0) + 2$

$\Rightarrow y = 0 + 2$

$\Rightarrow y = 2$

So this gives us the ordered pair,

$(0,2)$

When
$y = 0$
we get,

$0= \frac{1}{3} x + 2$

$\Rightarrow \: - 2 = \frac{1}{3} x$

$\Rightarrow \: - 2 \times 3= x$

$\Rightarrow \: -6= x$
This also gives the ordered pair

$(-6,0).$

We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.

For the second line

$y = - x - 2$

We again find the intercepts and plot them.

When
$x = 0$

$y = - 0 - 2$

$\Rightarrow \: y = - 2$

This gives the ordered pair

$(0,-2)$

Also, when
$y = 0$

then we have,

$0 = - x - 2$

$2 = - x$

$x = - 2$

Then we again have the ordered pair,

$(-2,0)$

We plot these two points on the same graph sheet to obtain the red graph above.

The intersection of the two lines is
$(-3,1)$

You will get good grades so don't worry much.

Negative angles are measured in which direction from standard position?

NNADVOKAT [17]

Answer:

Clockwise

Step-by-step explanation:

The angle is measured from the initial side to the terminal side by the amount of rotation. The measurement is positive if measured in a counterclockwise direction. The measurement is negative if measured in a clockwise direction.
