Answer:
What is the constant variation of Y =- 2 3x?
The constant of variation, k , is 23 .
Step-by-step explanation:
When x is zero in a direct variation equation y will also be zero. That means that the y-intercept of all direct variation equations is always zero.
Answer:
It will take Jade (2x + 5) minutes
Step-by-step explanation:
Let us find the expression that represents the time Jade will take
∵ Binh takes x minutes to ride to his friend’s house
∴ The time Binh takes = x minutes
∵ 5 more means + 5
∵ Twice means × 2
∵ Jade takes 5 minutes more than twice as long as Binh to ride to their
friend’s house
→ Multiply the time Binh takes by 2 and add the product by 5
∵ Binh takes x minutes
∴ The time Jade takes = 2 × x + 5
∴ The time Jade takes = 2x + 5 minutes
∴ It will take Jade (2x + 5) minutes
Step-by-step explanation:
-36.8 + 9.2(2). [as the value of x is 2]
-36.8 + 18.4
= - 18.4 [as the number with the
Negative sign is greater]
The third one
U solve from left to right and when two negatives are next to each other it turns to a plus.
