Answer:

y= 3/13x + 2/13

Step-by-step explanation:

3x-13y=2

Subtract 3x from both side

-13y=-3x-2

Divide by -13

y= 3/13x + 2/13

Answer:

y = \frac{2-3x}{-13}

Step-by-step explanation:

=> 3x-13y = 2

Subtract 3x to both sides

=> -13y = 2-3x

Dividing both sides by -13

=> y = \frac{2-3x}{-13}

How many sides does a polygon have if the sum of the measure will of the interior is 10260
Klio2033 [76]

The polygon have 59 sides.

Solution:

Sum of the measure of interior angle of the polygon = 10260°

Interior angle theorem of polygon,

<em>The sum of measure of interior angles of a polygon is (n – 2) × 180°.</em>

By this theorem,

(n – 2) × 180° = 10260°

Divide by 180° on both sides.

$\frac{(n - 2) \times 180^\circ}{180^\circ}  = \frac{10260^\circ}{180^\circ}

n-2=57

Add 2 on both sides, we get

n – 2 + 2 = 57 + 2

n = 59

Hence the polygon have 59 sides.

Which statement about the following equation is true?
spayn [35]

The given expression is

3x^2 -8x +5 = 5x^2

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is

5x^2 -3x^2 +8x -5=0

2x^2+ 8x -5 =0

The formula of discriminant is

D =b^2 -4ac

Substituting the values of a,b and c, we will get

D = 8^2 -4(2)(-5)=64+40 = 104

And since the discriminant is greater than 0, or it is positive so we have two real roots.

Therefore the correct option is B .
