(x – 4)(x + 10) = -17
pogonyaev

Answer:

-3 +   4sqrt(2)

-3  -  4sqrt(2)

Step-by-step explanation:

(x – 4)(x + 10) = -17

FOIL on the left hand side  (First outer inner last)

x^2 +10x-4x-40 = -17

x^2 +6x-40 =-17

Add 17 to each side

x^2 +6x-40+17 =-17+17

x^2 +6x -23 = 0

Using the quadratic formula

-b + - sqrt(b^2 -4ac)

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

   2a        

where ax^2 +bx+c=0

-6 + - sqrt(6^2 -4*1*-23)

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

   2*1

-6 + - sqrt(36 +92)

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

   2

-6 + - sqrt(128)

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

   2

-6 + -  8sqrt(2)

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

Trapezoid WKLX has vertices W(2, −3), K(4, −3), L(5, −2) , and X(1, −2) . Trapezoid WKLX ​ is translated 4 units right and 3 uni
guapka [62]
Okay, so first of all, if the trapezoid was translated right 4,
Then all the (x)'s should be 4 more than the original value
For example: (2,-3) <span>→ (6,-3)
Now since the Trapezoid was translated down 3,
Then all the (y)'s should be 3 less than the original value
For example: (2,-3) </span><span>→ (2,-6)
Now do this to all the Vertices
</span>(6,-6)(8,-6)(9,-5)(5,-5)
Final Answer: <span>Option 2</span>

Jerry bought 5 candy bars for $14.75. if the king size candy bar cost $3.75 and a regular size candy bar cost $1.75, how much of
Arturiano [62]

Answer:

King size(x): 3

Regular size(y): 2

Steps:

System of Equations:

x+y = 5

3.75x+1.75y = 14.75

Multiply 3.75 on all sides.

3.75x+3.75y = 18.75

3.75x+1.75y = 14.75

Subtract top and bottom

            2y  = 4

            /2      /2

             y   =  2

After you know regular size amount, figure out king size ----3.

5-2 = 3.
