If f(x)=-4x^2-6x-1 and g(x)=-x^2-5x+3 find (f+g)(x) PLS ANSWER FAST!
arlik [135]
When you do (f+g)(x), all you have to do is take both functions and add them to each other. It should look like this when you set it up:
(f + g)(x) = (4x {}^{2}  - 6x - 1) + (x {}^{2}  - 5x + 3)
Then just add like terms and you should get:
(f + g)(x) = 5x {}^{2}  - 11x + 2
Hope this helped.

Convert the decimal expansion 0.1777 into a rational number
Helen [10]

Answer:

The rational form of the given number 0.1777  = \frac{1777}{10,000}

Step-by-step explanation:

The rational number is expressed as a number on the form of (\frac{p}{q} ) , q \neq 0

Now,here the given number in decimal form = 0.1777

To remove the decimal, firstly count the number of digits AFTER DECIMAL.

Here, number of digits after decimal = 4

SO, the decimal can be removed and replaced by 1 , by dividing with 1,0000.

\implies 0.1777  = \frac{01,777} {10,000}  = \frac{1777}{10,000}

Hence, the rational form of the given number 0.1777  = \frac{1777}{10,000}

Help on this please?
Anna [14]

Answer:

angle 1 should equal to 54.

angle 2 should equal to 126.

Step-by-step explanation:

2x - 8 + 4x + 2 = 180

2x + 4x - 8 + 2 = 180

6x - 6 = 180

6x - 6 + 6 = 180 + 6

6x = 186

6x ÷ 6 = 186 ÷ 6

x = 31

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

2x - 8 = A1

2(31) - 8 = A1

62 - 8 = A1

54 = A1

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

4x + 2 = A2

4(31) + 2 = A2

124 + 2 = A2

126 = A2
