What is the equation of the line —3x – 2y = 30 in slope-intercept form?

Answers

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 3x - 2y = 30 ( add 3x to both sides )

- 2y = 3x + 30 ( divide terms by - 2 )

y = - [tex]\frac{3}{2}[/tex] x - 15 ← in slope- intercept form

(a) 85% of 80 is what number?
(b) 21 is 35% of what?

Answers

Answer:

a) 68

b)60

Step-by-step explanation:

a) 85% = 0.85

0.85 * 80 = 68

b) let x be the unknown number.

35% = 0.35

0.35x = 21

x = 60

Answer:

Step-by-step explanation:

a, 85% of 80

85% of 80

= 85/100*80

=85/100*80

=0.85*80

=68.

b, 21 is 35%

21 is 35%

=21*35/100

=21*0.35

=7.35.

Use the information given to write an equation in standard form.

6. Slope is 3, and (1. 4) is on the line.

7. Slope is -2, and (4,3) is on the line.

10. Slope is , and (1, 3) is on the line.

11. Slope - , and (2, 3) is on the line

Answers

The correct answers are:

6. 3x-y=-1

In slope intercept form this equation has a slope of 3 and point 1,4 is included on the graphed line: y=3x+1 is slope intercept form.

7. 2x+y=11

In slope intercept form this equation has a slope of -2 and point 4,3 is included on the graphed line: y=-2x+11 is slope intercept form

10. 4x-7y=-17

In slope intercept form this equation has a slope of 4/7 and point 1,3 is included on the graphed line: y=4/7x+17/7 is slope intercept form


11. 3x+2y=12

In slope intercept form this equation has a slope of -3/2 and point 2,3 is included on the graphed line: y=-3/2x+6 is slope intercept form


You basically just find the slope intercept form of each question then convert the intercept form over to standard form then graph in intercept form to see if the point lies on the line :)

find the missing side lengths. leave your answers as radicals in simplest form.
x=?
y=?​

Answers

Answer:

y = 2

x = 4

Step-by-step explanation:

The given is a special right triangle, the measure of its interior angles is as follows:

90-60-30 and side lengths would be:

2a - a[tex]\sqrt{3}[/tex] - a

as shown in image the side length that sees angle measure 60 is 2[tex]\sqrt{3}[/tex]

so the number represented by a is = 2 therefore y = 2 and x = 4

The sum of the interior angles of a polygon is 2700 degrees. Calculate the number of sides.

Answers

Answer:

17 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 2700° , then

180°(n - 2) = 2700° ( divide both sides by 180° )

n - 2 = 15 ( add 2 to both sides )

n = 17

The polygon has 17 sides
