Answer:
D 7i
Step-by-step explanation:
sqrt(-49)
We know that sqrt(ab) = sqrt(a) sqrt(b)
sqrt(49) sqrt(-1)
We know that sqrt(-1) = i
Taking the principal square root of 49
7i
Write as a function equation: where f(x) is the same as "y"
f(x) = 5 + 1x ------ y = 1x + 5
Use: y = mx + b (Where m = slope and b is y intercept)
Slope is 1 and y intercept is +5
Remember slope is rise over run so 1 can be written as 1 / 1 and interpreted as rise 1 and run 1 both in the positive direction.
The probability of a 2 or a 5 is 50%
Answer: 14, 48, 50
Step-by-step explanation:
14^2+48^2=50^2
Answer:
x = 4
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the remote interior angles.
18x +5 = (46) +(-1 +8x)
10x = 40 . . . . . . . . . . . . . subtract (5+8x) from both sides, simplify
x = 4 . . . . . . divide by 10

<em>Additional comment</em>
The exterior angle is (18)(4) +5 = 77°. The marked unknown interior angle is -1+(8)(4) = 31°. The sum of the two remote interior angles is 46°+31° = 77°. The unmarked interior angle is 180°-77° = 103°.
