Answer:

x=26

Step-by-step explanation:

X +64 is equal to 90 degrees

The angles are complementary

x+64=90

Subtract 64 from each side

x+64-64 =90-64

x =26

Tanya [424]

Answer:

33i - 12

Step-by-step explanation:

8i - (12 - 4i) + 7 \sqrt{ - 9}   \\  = 8i - 12  + 4i + 7 \sqrt{9  \times ( - 1)}  \\ = 12i - 12 + 7 \times 3 \sqrt{ - 1}  \\ = 12i - 12 + 21i  \:  \: ( \because  \sqrt{ - 1} = i)\\  = 12i + 21i - 12 \\   \therefore \red{ \bold{8i - (12 - 4i) + 7 \sqrt{ - 9} }=  \purple{ \bold{33i - 12}}}

What is the range of the function for the given domain? y = 2x − 5 D: {-2, 0, 2, 4}
rosijanka [135]

Answer:

Range of Function :  { - 9, - 5, - 1,  4 }

Step-by-step explanation:

We know that y = 2x - 5 provided the domain ( x - values ) { - 2, 0, 2, 4 }. Let us substitute each element in this set of domain as x in the equation "y = 2x - 5" as to solve for the y - values, otherwise known as the range of the function.

{ - 2, 0, 2, 4 }

y = 2( - 2 ) - 5 = - 9,

y = 2( 0 ) - 5 = - 5,

y = 2( 2 ) - 5 = - 1,

y = 2( 4 ) - 5 = 4

We have the set of y - values as { - 9, - 5, - 1, 4 }. This is the range of our function.
