Answer:
Therefore the value of given expression when r = 14 and s = 8 is
Step-by-step explanation:
Given:
To Find:
Value of above equation when r = 14 and s = 8
Solution:
.............Given
Put,
Now 7 × 2 = 14 and 8 will cancel each other we get
Therefore the value of given expression is
To find the percent of a fraction you have to find the decimal first. 11/50=.22
To turn a decimal into a fraction you put the decimal two places back;22.00. The answer should be 22%
So if the line is linear we can use slope intercept form to find the equation of the points: y=mx+b
To calculate m, the slope we subtract two of the points (I’ll use the first two):
(-1, 1)
(4, 0)
This equals 0-1/4+1, which simplifies to -1/5
So the slope is -1/5 and we can put that into slope intercept form along with a point to get b, the y-intercept.
So, y=-1/5x+b
Now we substitute x and y with a point.
1=-1/5(-1)+b
1=1/5+b
b=4/5
So the equation is:
y=-1/5x+4/5

<span>It is estimated that the city of Houston, Texas, will double in size every 35 years:
</span>P=Po(2)^(t/35)
<span>If the population is currently 2.4 million people:
Po=2.4 millions
</span><span>How many people will there be in 20 years?
t=20 years, P=?
P=(2.4 millions)(2)^(t/35)
P=(2.4 millions)(2)^(20/35)
P=(2.4 millions)(2)^(0.571428571)
P=(2.4 millions)(1.485994289)
P=3.566386294 millions
P=3.6 millions
Answer: There will be 3.6 million people in 20 years.</span>
Answer:
X=16
Step-by-step explanation:
1/4x-1=3
1/4x=3+1
1/4x=4
(4)1/4x=4(4)
x=16
