Answer:

x=−5 and y=−1

Step-by-step explanation:

Let's solve your system by substitution.

y=2x+9;y=−x−6

Step: Solvey=2x+9for y:

y=2x+9

Step: Substitute2x+9foryiny=−x−6:

y=−x−6

2x+9=−x−6

2x+9+x=−x−6+x(Add x to both sides)

3x+9=−6

3x+9+−9=−6+−9(Add -9 to both sides)

3x=−15

3x

3

=

−15

3

(Divide both sides by 3)

x=−5

Step: Substitute−5forxiny=2x+9:

y=2x+9

y=(2)(−5)+9

y=−1(Simplify both sides of the equation)

Hope this helps!

A candy box measures 8.2 cm in diameter and 15 cm in height. How many 2 cm cubed pieces of candy can fit into the box?
Katarina [22]
60 2cm candy prices can fit because if you multiply 8.2 by 15 it equals a decimal and if you divide it by 2 that the nearest whole number you’ll get is 60, so the answer has to be 60.
