I'll solve for y
xy+(4(20))>x-5y(2+9-7)
xy+4(20)>x-5y(2+9-7)
xy+4(20)>x-5y(4)
xy+4(20)>x-20y
xy+80>x-20y
xy+20y+80>x
y(x+20)>-80+x
y>(-80+x)/(x+20)
Answer:
75%
Step-by-step explanation:
(Distance he would ride the bus / total distance ) x 100
Convert 2 km to meters
1km = 1000 meters
2km = 1000 x 2 = 2000 meters
Distance he would ride the bus = 2000 - 500 = 1500
(1500 / 2000) x 100 = 75%
1. The answer would be true
<span>Part A: Does the table represent y as a function of x? Justify your answer.
The function of x is "</span><span>fifth powers of x" which can be write as
</span>f(x)= x^5
To determine whether the y represent f(x), you can try to put a value of x into the function, then compare the value of f(x) with y.
For x=1 and y=1
f(x)= x^5
f(1)= 1^5
f(1)= 1 = y
For x=2 and y=32
f(x)= x^5
f(2)= 2^5
f(2)= 32 = y
2.
<span>What is the value of f(4) and what does f(4) represent?
The f(4) means putting 4 as the x value. In the function, the f(x) represent price </span>for renting a bowling lane and the variable x represent the number of hours. Then f(4) represent the price for renting a bowling lane for 4 hours.
The value would be:
<span>f(x) = 2x + 12
</span><span>f(4) = 2(4) + 12
f(4)= 8+12= $20</span>
Answer:
5/18
Step-by-step explanation:
(36-12-12-2)/36=5/18
Answer:
<u>Step-by-step explanation:</u>
Factor both denominators to see which factors are missing from each denominator. Then multiply both fractions so they have the same LCD.
