Answer:

f(-7) = -3

Step-by-step explanation:

The exponentiation x^2 must be done before multiplication by the coefficient -1.  

Substituting -7 for x, we get:

-(-7)^2 +  6(-7) + 4 = f(-7)

Then f(-7) = -49 + 42 + 4, or

f(-7) = -3

How to convert improper fraction to mixed numbers
MakcuM [25]

Answer:

Step-by-step explanation:This is an improper fraction: 243/10 to convert it to a mixed number just do 243 divided by 10 which equals 24, so put that number as a whole number in front of the fraction, then do 24 times 10 which equals 240, then since 240 is 3 less than 243 the answer is 24 and 3/10.

If you need, I can try to explain it better.

The highest point in California is Mount Whitney at 14,494 feet above sea level. The lowest point is the Death Valley at 282 fee
barxatty [35]
Okay so in order to figure this out you have to realize that height (distance) cannot be negative. So all you do is add 282 feet from the mountain and 282 from the valley to get 564ft in the difference of elevations

What are the correct answers and why? Simple and concise explanation please!!!
dezoksy [38]

Answer:

\large\boxed{-\bigg[(x-3)^2+2x\bigg]+1}\\\\\boxed{-x^2+4x-8}

Step-by-step explanation:

(g\ \circ\ f)(x)=g\bigg(f(x)\bigg)

f(x)=(x-3)^2+2x\\\\g(x)=-x+1\\\\g\ \circ\ f\to\text{put f(x) instead of x in the function g(x)}:\\\\(g\ \circ\ f)(x)=-\bigg[\underbrace{(x-3)^2+2x}_{x}\bigg]+1

-----------------------------------------

-\bigg[(x-3)^2+2x\bigg]+1=-(x-3)^2-2x+1\\\\\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\=-(x^2-(2)(x)(3)+3^2)-2x+1=-(x^2-6x+9)-2x+1\\\\=-x^2-(-6x)-9-2x+1=-x^2+6x-9-2x+1\\\\\text{combine like terms}\\\\=-x^2+(6x-2x)+(-9+1)=-x^2+4x-8

-----------------------------------

-x^2+4x-8=-x^2+4x-2^2+2^2-8=-(x^2-4x+2^2)+4-8\\\\=-(\underbrace{x^2-(2)(x)(2)+2^2}_{(a-b)^2=a^2-2ab+b^2})-4=-(x-2)^2-4=-(x+1-3)^2-4

In\ (-x+1-3)^2+2x,\ x^2\ will\ be\ positive.\\In\ (-x+1-3)^2+2(-x+1),\ x^2\ will\ be\ positive.

Find three consecutive integers whose sum is 57????
Setler79 [48]

Answer:18 19 20

Step-by-step explanation:"Consecutive"  means that the integers will follow each other in value, for example:  1, 2, 3 or 4, 5, 6.  Also, no decimals are needed here because "integers" are whole, counting numbers. Here is the set up:   Let x= the first integer     Then    X+1= 2nd consecutive integer   and x+2= 3rd  .  

Suppose that x=1   x+1= 1+1=2   and x+2=1+2=3   However, you need specific consecutive numbers whose sum is 57.  Remember that sum means to add:

x+  (x+1)  + (x+2) = 57                 Addition of all 3 consecutive numbers   Now solve for x

                                                   and substitute into each part to come up with the three integers:

3x + 3= 57        3x=54               x=54/3  =  18            x=18,   x+1= 18+1=19      x+2=18+2=20

Check your answer:  18+19+20=57                 57=57  Check
