Answer:

D'(-1, 1)
E'(-4, 8)
F'(-8, 8)

Step-by-step explanation:

The coordinates of the given vertices are ...

D(1, 1)
E(4, 8)
F(8, 8)

Reflection across the y-axis changes the sign of the x-coordinate:

(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis

This means the reflected figure has coordinates ...

D(1, 1) ⇒ D'(-1, 1)

E(4, 8) ⇒ E'(-4, 8)

F(8, 8) ⇒ F'(-8, 8)

Three students, Matthew, Thompson and Amos shared #15000 in the ratio of 5:2:x respectively. If Matthew's share is 7500, calcula

jasenka [17]

Answer:

The value of x is 3.

Step-by-step explanation:

Matthew earned 7500 of 15000, which is exactly half the total amount, meaning that the fraction corresponding to his earnings is 1/2.

Rate of 5:2:x, with number 5 corresponding to Matthew, mean that his fraction of the earnings, in function of x is given by:

$\frac{5}{5 + 2 + x} = \frac{5}{7 + x}$

Both fractions are equal, so:

$\frac{5}{7 + x} = \frac{1}{2}$

Applying cross multiplication:

$7 + x = 10$

$x = 10 - 7$

$x = 3$

The value of x is 3.
