14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10
Answer:
1/6
Step-by-step explanation:
Divide by 3
9/54 = 3 / 18
You can again divide by 3 for the answer
1/6
Answer:
![y=-55x+570](https://tex.z-dn.net/?f=y%3D-55x%2B570)
Step-by-step explanation:
The correct question is
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Let
x -----> the time in hours
y ----> the number of pages left to read
we know that
The linear equation in point-slope form is equal to
![y-y1=m(x-x1)](https://tex.z-dn.net/?f=y-y1%3Dm%28x-x1%29)
In this problem we have
----> is negative because the linear function is decreasing
![point\ (4,350)](https://tex.z-dn.net/?f=point%5C%20%284%2C350%29)
substitute
![y-350=-55(x-4)](https://tex.z-dn.net/?f=y-350%3D-55%28x-4%29)
![y-350=-55x+220](https://tex.z-dn.net/?f=y-350%3D-55x%2B220)
![y=-55x+220+350](https://tex.z-dn.net/?f=y%3D-55x%2B220%2B350)
![y=-55x+570](https://tex.z-dn.net/?f=y%3D-55x%2B570)
Take the whole and multiply it by the percentage
so...
660 * .4 = 264
