What is the axis of symmetry for f(x) = 2x2 + 4x + 2? (1 point)
yKpoI14uk [10]
For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a

f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1

the axis of symmetry is x=-1

What is the equation of the line that passes through the point (3,-7) and has a slope of -4/3?
Gemiola [76]

Answer:

4x + 3y + 9 = 0

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here, $ m = \frac{-4}{3} $ and $ (x_1 , y_1) = (3 , -7) $.

Substituting in the formula y +  7 = \frac{-4}{3} (x - 3)

$ \implies 3y + 21 = -4x + 12 $

$ 4x + 3y + 9 = 0 $

While on vacation Craig bought a pair of sunglasses for $15.98 for $7.99 5 postcards and a beach towel the beach towel cost 0.50
NISA [10]

Answer:

$0.79.

Step-by-step explanation:

Let T= The price of beach towel,

P = The cost of each postcard.

S = The cost of sunglasses.

H = The cost of hat.

We have been given that while on vacation Craig bought a pair of sunglasses for $15.98. The beach towel cost 0.50 cents more than half the price of sunglasses.

We can set this information in an equation as:

T=\frac{15.98}{2}+0.50

T=7.99+0.50  

T=8.49  

We are told that Craig gave the cashier $40 and got 3.59 change and each postcard cost the same. So we can set this information in an equation as:

T+5P+S+H=40-3.59

Let us substitute our given values.

8.49+5P+15.98+7.99=40-3.59  

Let us combine like terms.    

32.46+5P=36.41      

Let us subtract 32.46 from both sides of our equation.

32.46-32.46+5P=36.41-32.46

5P=3.95  

Let us divide both sides of our equation by 5.

\frac{5P}{5}=\frac{3.95}{5}  

P=0.79  

Therefore, each postcard costs $0.79.
