Answer:
y = 2x
Step-by-step explanation:
Maria uses 2 centimeters of tape for each present she wraps, and we want a equation that shows the relationship between the number of presents x and the tape used y. To do this, we can establish a rule of three with the information given:
1 present wrapped -> 2 centimeters of tape
x presents wrapped -> y centimeters of tape
1/x = 2/y
x = y/2 -> y = 2x
From this relation, we know that to make x presents, Maria will use 2x centimeters of tape.
Slope intercept form : y = mx + b
4x - 5y < 1
-5y < -4x + 1
y > 4/5x - 1/5 <== slope intercept form
y - x > 3
y > x + 3 <== slope intercept form
Answer:
x=-4 and y=4
Step-by-step explanation:
(6x+9y)-(6x+7y)=12-4=8
--> 9y-7y=8
-->2y=8-->y=4
-->6x+7×4=4 -->x=-4
