Answer:
x= 200
Step-by-step explanation:
The given equation is:
1/5 x - 2/3 y = 30
The value of y is 15
Put the value of y in the given equation:
1/5 x - 2/3(15) = 30
1/5 x- 10 = 30
Take the L.C.M of the denominator
x-50/5 = 30
Move the denominator to the R.H.S
x-50 = 30*5
x-50 = 150
Combine the like terms
x= 150+50
x = 200
The value of x is 200...
Arguably, all of them are at least somewhat biased, but the most biased would be <span>surveying people 15 to 20 years old leaving a concert </span> because being at a concert would be highly correlated with liking the type of music played at that concert.
The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
<h3>The linear equation of the graph</h3>
The equation of the line of best fit is given as:
When the number of pictures added is 700, we have:
y = 700
Substitute 700 for y in
Subtract 367 from both sides of the equation
Rewrite the above equation as:
Divide both sides by 8
Remove decimal (do not approximate)
This means that:
Hence, the Tampa Tribune expecting to add 700 new pictures per year to their database in 2041

Step-by-step explanation:
Answer: The vertex of the parabola (quadratic function) is (-2,-4)
Fourth option: (-2,-4)
Solution:
y=x^2+4x
y=ax^2+bx+c; a=1, b=4, c=0
Vertex: V=(h,k)
h=-b/(2a)
h=-4/(2(1))
h=-4/2
h=-2
y=x^2+4x
k=y=h^2+4h
k=(-2)^2+4(-2)
k=4-8
k=-4
Vertex: V=(h,k)
Vertex: V=( -2, -4)
