a graph showing inequalities “greater than or equal to” or less than equal to” will use dotted lines. true or false

1 answer:

4 0

This is true. A solid line means that anything behind the line is true, but dotted lines mean that points on the line are also solutions. In other words, the dotted line is the "equal to" in "greater than or equal to", so this is true.

A right angle intersects a line at point M. Which statement is true about angles 1 and 2? They are congruent. They are right ang

yulyashka [42]

The angle show with the yellow square has a measure of 90°.

Together with angles 1 and 2, they form a straight angle so we have:

∠1+∠2+90°=180°,

subtracting 90° from both sides we have:

∠1+∠2=90°

If the sum of the measures of 2 angles is 90°, the angles are called complementary.

Since the sum of the measures of angles 1 and 2 is 90°, then these 2 angles are complementary.

Answer: They are complementary

If dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3

Lapatulllka [165]

Answer:

The equation of the tangent line passing through the point (-2,3) is

4 x + y +5 =0

Step-by-step explanation:

Step(i):-

Given that the slope of the tangent

$m = \frac{dy}{dx} = x(y-1)$

m = -2( 3-1) = -4

Given point x = -2

y = f(-2) =3

∴The given point ( x₁ , y₁) = ( -2 ,3)

Step(ii):-

The equation of the tangent line passing through the point (-2,3)

$y - y_{1} = m(x-x_{1} )$

$y -3 = -4(x-(-2))$

y -3 = -4( x+2)

y-3 = -4x -8

4x + y -3+8=0

4x +y +5=0

Step(iii):-

The equation of the tangent line passing through the point (-2,3) is

4 x + y +5 =0

Find the quotient of 95 and 3.25

Lelu [443]

To find the quotient of 95 and 3.25 we may do something like this:

95 ÷ 3.25 =
= 95 ÷ 3 1/4 =
= 95 ÷ 13/4 =
= 95 * 4/13 =
= 380/13 =
= 29 3/13

I hope it'll help you :)
