2x+y=-6<br><br>what are the x and y intercepts​
Deffense [45]

Answer:

Step-by-step explanation:

y intercept

To find the y intercept, make x = 0

2(0) + y = - 6    zero times anything is 0

0 + y = -6        

The y intercept  is (0,-6)

x intercept

The x intercept happens when y = 0

2x + 0 = -6        zero added to anything = whatever you started with.

2x = - 6             Divide by 2

2x/2 = -6/2       Do the division

x = - 3

The x intercept = (-3,0)

An angle of a right triangle measures 65 degrees. If the length of the side opposite to the angle is 20 ft, what are the lengths
igomit [66]

Answer:

22.07 ft & 9.32 ft

Step-by-step explanation:

by sines rule :

20/sin 65° = r/sin 90° = y/sin 25°

r = 20×sin 90°/sin 65° = 20/0.9063

= 22.07 ft

y = 20×sin 25°/sin 65° =

20× 0.4226/0.9063

= 9.32 ft

NEED HELP A triangle is cut from a rectangle. The height of the triangle is half of the unknown side length s. The area of the s
Nesterboy [21]

Answer: 14s - 7s/2 = 84

Step-by-step explanation:

Given that s is the length of the unknown side:

Area of the shaded region = 84

Area of rectangle - Area of triangle = 84

Area of rectangle = L * W

= 14 * s

= 14s

Area of triangle = ¹/₂ * base * height

= ¹/₂ * 14 * s/2

= 7s/2

Area of shaded region:

14s - 7s/2 = 84

Solving for s:

14s - 7s/2 = 84

28s - 7s = 168

21s = 168

s = 168/21

s = 8 inches
