Can someone help me?

Exterior angle = Sum of its interior opposite angles ( exterior angle property )

Which means :-

Then :-

1) ∠ 7x - 1

= 7 × 10 - 1

= 70 - 1

2) ∠14x - 8

= 14 × 10 - 8

= 140 - 8

As the sum of interior opposite angles of this triangle is equivalent to the value of the exterior angle (69+63=132), we can conclude that we have found out the correct value of x .

Therefore , the value of x = 10 .

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
