So if an equation was f(x)=x+4

you would automatically change f(x) into y

so it would y-y=x(x-x)

so you plug in the x and 4 which is the first y and x

y-4=x(x-x)

you switch the numbers around

so your final answer would be x-4

What is the product of (2x2 + 5x - 3) and (3x +7)?

kicyunya [14]

Answer:

6x^3 + 29x^2 + 26x -21

Step-by-step explanation:

(2x^2 + 5x -3)(3x + 7) = 6x^3 + 14x^2 + 15x^2 + 35x - 9x -21

= 6x^3 + 29x^2 + 26x -21

A statue is mounted on top of a 42 foot hill. From the base of the hill to where you are standing is 73 feet and the statue subt

larisa [96]

Answer:

19.72 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between angles and sides of a right triangle:

Tan = Opposite/Adjacent

Then the relations in the attached drawing are ...

tan(α) = 42/73

tan(α +10.3°) = (42 +SH)/73

Solving the first equation for α, we get ...

α = arctan(42/73)

Solving the second equation for SH, we get ...

73 tan(α +10.3°) = 42 +SH

SH = 73·tan(arctan(42/73) +10.3°) -42 = 73·tan(29.91°+10.3°) -42

SH = 73·0.84547 -42 = 19.720 . . . . feet

The height of the statue is about 19.72 feet.

Laura got a discount of 100 dollars on her purchase of a 5775 bed.What is the percent of decrease?

matrenka [14]

Remember that percent means parts out of 100
x/100

discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100
1.73/100=1.73%
round
2%
