Answer:
- 8
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 3, 5 ]
From the table
f(b) = f(5) = - 26
f(a) = f(3) = - 10
Hence
average rate of change = 
= 
= - 8
34000001.8 is the answer to this problem!
1.8000000+34000000!
There are four different choices. Now we have to find which choice best expresses the inequality 1.25x-6.50>50
1.25x has positive sign so any statement that indicates earning like sells at the rate of 1.25 will match with expression 1.25x.
Now -6.50 has negative sign that means this quantity must be subtracted or represents loss of any kind.
Keeping above sign in mind and reading the given statementns, we see that only choice "a" first the given inequality.
Hence final answer is a).
hello :<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -7 and b = -1 (Center at: A(-7,-1) )
r = AP.... P(8,7)
r² = (AP)²
r² = (8+7)² +(7+1)² =225+64=289 ...... so : r = 17
an equation of the circle that satisfies the stated conditions.
Center at </span></span>A(-7,-1), passing through P(8, 7) is :
(x+7)² +(y+1)² = 289
The point (-15,y ) <span>lies on this circle : (-15+7)² +(y+1)² = 289....(subsct : x= -15)
(y+1)² = 225
(y+1)² = 15²
y+1 = 15 or y+1 = -15
y = 14 or y = -16
you have two points : (-15,14) , (-15, -16)</span>
Answer:
Here you go sorry.
Step-by-step explanation:
Question 1.
y = 4x - 8 has a slope of 4. Since parallel lines have equal slopes, the slope of your new line will also be 4.
Now, you have a point (3,9) and a slope 4. Use the Point-Slope Form for the equation of a line.
y - y1 = m(x - x1)
y - 9 = 4(x - 3)
y - 9 = 4x - 12
y = 4x - 3
Question 2.
Since it is parallel, it must have the same slope.
y = (1/2)x + b
Find b from the given point.
4 = (1/2)(2) + b
b = 3
y = (1/2)x + 3
