Answer:
Slope is -2/9 and y intercept is (0,2)
Step-by-step explanation:
Given:
1 pack = 5 pencils and cardboard.
1 pack must be between 60 grams and 95 grams
60g < x < 95g ; where x represents 1 pack.
Card board: 15 grams.
95g - 15g = 80g maximum total weight of 5 pencils
80g / 5 = 16g maximum weight of a single pencil
60g - 15g = 45g minimum total weight of 5 pencils
45g / 5 =9g minimum weight of a single pencil
9 < x < 16 ; where x represents a single pencil in the pack.
Answer:
7
Step-by-step explanation:
7√5÷5
5/5= 1 then,
√1=1
hence 7(1)=7
Answer:
y = 5 and y = 1
Step-by-step explanation:
⇒ (3y - 2)² + 7 - 7 = 43 - 7
⇒ (3y - 2)² = 36
⇒ √(3y - 9)² = √36
⇒ 3y - 9 = ±6
⇒ 3y - 9 + 9 = 6 + 9
⇒ 3y = 15
⇒ 3y/3 = 15/3
⇒ y = 5
⇒ 3y - 9 + 9 = -6 + 9
⇒ 3y = 3
⇒ 3y/3 = 3/3
⇒ y = 1
Answer:
y=88
x=92
Step-by-step explanation:
i know that a triangle angles always add up to 180 so for x 39+49=88 and 180-88=92 so x is 92
to find y you would add the opposite interior angles which are 39 and 49 so the exterior angle is 88
y=88
x=92
