Answer:
3
Step-by-step explanation:
The value of "a" is the coefficient of x^2, so we know that is 2.
__
<u>Solve for h</u>
Now, we have ...
2x^2 -8x +7 = 2(x -h)^2 +k
Expanding the right side gives us ...
= 2(x^2 -2hx +h^2) +k
= 2x^2 -4hx +2h^2 +k
Comparing x-terms, we see ...
-4hx = -8x
h = (-8x)/(-4x) = 2
__
<u>Solve for k</u>
Now, we're left with ...
2h^2 +k = 7 = 2(2^2) +k = 8 +k
Subtracting 8 we find k to be ...
k = 7 -8 = -1
__
And the sum of constants a, h, and k is ...
a +h +k = 2 +2 -1 = 3
The sum of the constants is 3.
The answer is true.
Really all you ever need is two points and you should find an equation.
Answer:
The answer is false
Step-by-step explanation:
The product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.
<h3>How to Find the
Product of Negative Numbers?</h3>
The rule when multiplying two negative numbers is that, the negative signs will cancel each other. That is, minus multiplied by minus will give as plus.
For example, -a × -b = ab
Also, "plus" multiplied by "minus" will also give as "minus. For example:
-a × b = -ab.
Using the above rule, let's find the product of the following:
−3 × 5 × (−6) × 4 = -15 × (-24)
−3 × 5 × (−6) × 4 = 360 [minus × minus = plus]
−7 × (−3) × (−9) × 0 = 0 [anything multiplied by 0 must result to 0]
−4 × (−6) × (−3) × (−5)
= 24 × 15
−4 × (−6) × (−3) × (−5) = 360
−3 × 4 × (−2) × (−7)
= -12 × 14
−3 × 4 × (−2) × (−7) = -168
Therefore, the product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.
