Answer:
-29 and -12
Step-by-step explanation:
First, we determine that the given equation in this item
is a linear equation. Thus, it should be a straight line. With this, we are
left with the third and fourth choice. Then, we substitute the given data
points to the equation and see if the points satisfy the given.
Choice 3:
<span> (1,3) :
(-5)(1) + (2)(3) = 1 TRUE</span>
<span> (3,8) :
(-5)(3) + 2(8) = 1 TRUE</span>
<span> (-3,-7)
: (-5)(-3) + (2)(-7) = 1 TRUE</span>
Choice 4:
<span> (4,-3) :
(-5)(4) + (2)(-3) ≠ 1 FALSE</span>
<span> (-1,2) : (-5)(-1) + (2)(2) ≠ 1 FALSE</span>
<span> (-4,5) : (-5)(-4) + (2)(5) ≠ 1 FALSE</span>
<span>Thus, the answer is the third choice.</span>
Answer:
It will take Walter 112.5 minutes to complete the project by himself
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Together rate: 1/45
George's rate: 1/75
Walter's rate: 1/x
How long will it take Walter to complete the project by himself?
This is x. So
It will take Walter 112.5 minutes to complete the project by himself
Given f(x)=<span>(2x2 − 7x)(−x2 − 7) the value of f'(3) will be a s follows:
f(x)=-2x^4+7x^3-14x^2+49x
thus from above:
f'(x)=-8x^3+21x^2-28x+49
thus
f'(3)=-8(3)^3+21(-3)^2-28(-3)+49
f'(3)=106
Answer: f'(3)=106</span>
