The Problem which coordinate is a solution to the equation: 7x + 4y = 9?
a (4, -2)
b. (-33)
c. (3-3)
d. (-4,2)

C. (3,-3)

Step-by-step explanation:

7 ( 4) + 4 (-2) = 9 false

7 ( -3) + 4 (3) = 9 false

7 ( 3) + 4 ( -3) = 9 true

7 ( -4) + 4 ( 2) = 9 false

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
