Slope intercept form is y = mx + c.

(where m is the slope, and c is the intercept - hence slope intercept form)

So all you have to do is rearrange the inequality to have y by itself.

-6x + 3y > - 45 (add 6x to both sides)

3y > - 45 + 6x (divide both sides by 3)

y > - 15 + 2x (put the 2x infront of the - 15)

y > 2x - 15

Answer:

y > 2x - 15

Use a graphing calculator to approximate the vertex of the graph of the parabola defined by the following

vivado [14]

Answer: (-0.4, 6.8)

The graph is attached

Step-by-step explanation:

We can find the axis of symmetry using the formula x = -b/2a

x = - -4/2(-5)

x = 4/-10

x = 0.04

Substitute for x and calculate y

y = $\left(0.4^{2}\right)\left(-5\right)-4\left(-0.4\right)\ +6$

y = 6.8

How do I solve this problem

Vaselesa [24]

C = 84 degrees

A = 2B
C = A + 20
A + B + C = 180

A = 2B
A/2 = B

A + (A/2) + (A+20) = 180
multiply each side by 2
2A + A + 2A + 40 = 360
combine like terms
5A + 40 = 360
subtract 40 from both sides
5A = 320
divide both sides by 5
A = 64

C = A + 20
C = 64 + 20
C = 84

The angles in a triangle are in the ratio 1:2:3 a) Show that the triangle is a right -angled triangle b) The hypotenuse of the t

Hitman42 [59]

Answer:

8.5 cm

Step-by-step explanation:

Angles of the triangle:

x+2x+3x= 180
6x= 180
x= 30

30°, 60° and 90°

Right triangle as it has 90° angle

Sides are a, b and 19 cm

sin 30°= a/19 ⇒ a= 19 sin 30°= 19*0.5= 8.5 cm = shortest side

sin 60°= b/19 ⇒ b= 19 sin 60°= 19*0.866= 16.45 cm
