Step-by-step explanation:

y = 4x – 5

-4x + y = -5

y = 2x + 3

-2x + y = 3

Elimination

-4x + y = -5

-2x + y = 3

__________--

-2x = -8

x = -8/-2

x = 4

Subsitution

-2x + y = 3

-2(4) + y = 3

-8 + y = 3

y = 3 + 8

y = 11

Shane and Karen want to measure the length of a soccer field. Should they use centimeters or meters to measure it? Explain.
Ber [7]

Shane and Karen want to measure the length of a soccer field. Length can be measured in different units such as cm, m ,km , yards etc. The question is asking us to select between two units cm or meters which will be more appropriate to measure the field.

To measure the field a larger unit is required. Meter is a bigger unit than centimeter.Centimeter is not the correct unit to measure the length of soccer field.

Shane and Karen should use meters to measure the soccer field.
