11x = 2y - 5
11x + 5 = 2y
2y = 11x + 5 (<u>a</u>x + b form)
y = (11x + 5)/2
y = 11x/2 + 5/2
The slope is <u>11/2</u>
Answer:
x = 10
Step-by-step explanation:
note that sin30° = 
Since the triangle is right use the sine ratio to find x
sin30° =
= 
multiply both sides by x
x ×
= 5 ( multiply both sides by 2 )
x = 10
Answer:
Since l and m are parallel,
let the angle next to (6x+7) be 'a'
then a will be equal to (3x - 16) since 3x-16 and a are corresponding angles
Since the 2 angles make a linear pair,
6x + 7 + 3x -16 = 180
9x -9 = 180
x -1 = 20
x = 21
Since the angles 11y-32 and 6x + 7 are vertically opposite,
11y - 32 = 6x + 7
11y - 32 = 6(21) + 7
11y = 126 + 39
11y = 165
y = 15
Answer:
-1
Step-by-step explanation:
The total number of minus signs is odd, so the product is negative.
(-1)^39 = -(1^39) = -1
