alexandr1967 [171]

$\bold{\huge{\orange{\underline{Solution}}}}$

$\bold{\underline{ Given :- }}$

While shopping for clothes Tracey spent 38$ less than 3 times of what Daniel spent

$\bold{\underline{ To\: Find :- }}$

We have to determine the total cost spent by daniel

$\bold{\underline{ Let's \: Begin :- }}$

Cost spent by Tracey for her clothes = 38$

Let assume the spending by Daniel is x

$\bold{\underline{Therefore ,}}$

$\sf{ x / 3 = 38 }$

$\sf{ x = 38 × 3 }$

$\sf{ x = 114 dollar }$

$\sf{\red{ Hence,\: Daniel\: spent\: 114 \: dollars\: on \: His\: clothes }}$

Which of the following is equivalent to f(x)?

Fynjy0 [20]

Answer:

D. $x^{-3/2}$

Step-by-step explanation:

Given function:

$f(x) = \frac{1}{x\sqrt{x} }$

Equivalent expression is:

$\frac{1}{x\sqrt{x} } = x^{-1}x^{-1/2} = x^{-1 - 1/2} = x^{-3/2}$

Correct choice is D

(HELP PLEASEE) The area of a rectangular swimming pool is 2x^2+13x-7. Find the dimensions of the swimming pool.

bearhunter [10]

Answer:

length =

$2x - 1$

width =

$x + 7$

Step-by-step explanation:

here we go,

=》

$2x {}^{2} + 13x - 7$

=》

$2 {x}^{2} + 14x - x - 7$

=》

$2x(x + 7) - 1(x + 7)$

=》

$(2x - 1)(x + 7)$

here, we got

the dimensions as :-

$(2x - 1) \: \: and \: \: (x + 7)$

Dylan and Javier had the same size serving of vegetables for dinner. Dylan finished 2/3 of his vegetables. Javier ate 4/6 of his

Bond [772]

Both because 2 x 3 is 6 2x2 is 4 and you get 4/6 so both have the same amount of vegetables

PLEASE HELP I WILL BRAINLIST

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

Since they intersect you can just solve for x and y

since y=-4x and y=x^2+2x+8, you can set -4x=x^2+2x+8

add 4x to both sides to make 0=x^2+6x+8

and factor out (x+4)(x+2)

so the solutions for x are -4 and -2

then insert the two values for x into the first equation

so y=-4(-4) and y=-4(-2)

so y=16 and y=8 when x=-4 and x=-2

so the smallest value for y in both equations is 8

Please give brainliest :)
