2(-5)+6=x
-10+6=x
-4=x

For the y, change the 3 to a -3

So your answer is (-4,-3)

1. Enrico sold a 10-pound box of assorted chocolates. Some of the chocolates in the box sold

N76 [4]

This shows that about 7 and 3 pounds of each chocolate were included in the mixture.

Let the number of pounds of both chocolates be x and y.

If Enrico sold a 10-pound box of assorted chocolates, hence;

x + y = 10 ................. 1

If some of the chocolates in the box sold for $1.75 per pound and some sold for $2.00 per pound with mixture sold for $1.90 per pound, then:

1.75x + 2x = 1.90 ................ 2

Solve equations 1 and 2 simultaneously.

x + y = 10 ................. 1 * 20

17.5x + 20x = 19 ................ 2 * 1

____________________________

20x + 20y = 200

17.5x + 20x = 19

Subtract

20x - 17.5x = 200 - 19

2.5x = 181x = 7.24

Substitute 7.24 into 1

x + y = 10

y = 10 - 7.24

x = 2.76

This shows that about 7 and 3 pounds of each chocolate were included in the mixture.

Find the y value for point F such that DF and EF form a 1:3 ratio. (5 points) Segment DE is shown. D is at negative 3, negative

SVETLANKA909090 [29]

I drew the segment and used Pythagorean theorem to solve for its measure. The line formed is the hypotenuse of the imaginary right triangle.

Among the choices only -1.33 and -1.25 is a feasible choice. But I am leaning towards -1.25 as the y-value of point F based on my diagram. Please see attachment.
