Answer:

Step-by-step explanation:

You are going to want to substitute the x of the function f(x) with the function of g(x) and replace the x in g(x) with -4

(f+g)(-4) = 4+3((-4)^2-3)

=43

hope this helped!

Step-by-step explanation:

% calculations are totally easy, if you remember to always find and the use 1%.

100% = $2.85

1% = 100%/100 = 2.85/100 = 0.0285

the price difference was

2.91 - 2.85 = $0.06

how many % are these $0.06 compared to yesterday's price ?

that is how many times 1% can fit into this number.

0.06 / 0.0285 = 2.105263158...%

so, rounded this is 2.1%

Consider the polynomial f(x)=2x^5-3x^4+x-6 (x )equals 2 x Superscript 5 Baseline minus 3 x Superscript 4 Baseline plus x minus 6

melamori03 [73]

Answer:

degree of polynomial = 5

leading term = $2x^{5}$

leading coefficient = 2

constant term = -6

Step-by-step explanation:

$f(x) = 2x^{5}-3x^{4}+x-6$

(i) The degree of the polynomial = 5. That is, the highest power of x

(ii) Leading term = $2x^{5}$ . This is the term with the highest power of x.

(iii) Leading Coefficient = 2. That is, the coefficient of the leading term ( $2x^{5}$ )

(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.

melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

$y$ is distance in miles, $x$ is time in hours.

The two equations are:

$y = \frac{20}{x} + 45$

$y = \frac{35}{x}$

Set them equal to each other and solve for x:

$\frac{35}{x} = \frac{20}{x} + 45$

$\frac{35}{x} - \frac{20}{x} = 45$

$\frac{35-20}{x} = 45$

$\frac{15}{x} = 45$

$x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes$

Plug that back into the equations to confirm this $x$ gives the same $y$ :

$y = \frac{20}{1/3} + 45 = 105 miles$

$y = \frac{35}{1/3} = 105 miles$
