Kelly saves $5 every week. Which expression represents the amount of money, in dollars, Kelly will save in w weeks
Svetradugi [14.3K]
Let's say x is the amount of money Kelly saves.  We do not know how many weeks she is saving.  If she was saving for 2, then the equation would be x=5(2).  However, she is saving by w weeks, so the equation is x=5w.

3x+y+z=4<br> 2x+2y+3z=3<br> X+3y+2z=5
zhenek [66]
1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2)    2x + 2y +3z  = 3
-   __________________
       4x - z            = 5

2)*3  6x + 6y + 9z = 9
3)*2  2x + 6y + 4z = 10
-      __________________
       <span>4x+5z             =-1

4x+5z = -1
4x - z =5
- ________
6z = -6
<u>z = -1
</u><u /><u>
</u>If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
<u>x=1</u>

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
<u>y=2

So z=-1, x=1, y=2</u>

Find the discriminant, describe the types of roots, and find the solution for 3x^2-24x+12
solniwko [45]
The discriminant of a polynomial is given by:
 b ^ 2-4ac
 Substituting the values we have:
 (-24) ^ 2-4 * (3) * (12) = 432
 Since the discriminator is greater than zero, then the roots are real.
 x = (- b +/- root (b ^ 2-4ac)) / (2a)
 Substituting the values:
 x = (- (- 24) +/- root (432) / (2 * (3))
 x = (- (- 24) +/- root (432) / (2 * (3))
 x = (- (- 24) +/- root (144 * 3) / (2 * (3))
 x = (24 +/- 12raiz (3) / (6)
 x = 4 +/- 2raiz (3)
 The roots are:
 x1 = 4 + 2raiz (3)
 x2 = 4 - 2raiz (3)
 Answer: 
 432
 the roots are real.
 
x1 = 4 + 2raiz (3)
 
x2 = 4 - 2raiz (3)

function g is a transformation of the parent function f(x)=x^2 the graph of g is a translation right 2 and down 5units of the gr
Natali [406]

right 3 units down 5 units

f(x)=x^2

right 3 units = (3,0)

down 5 units = (0,-5)

vertex = (h,k) therefore.

g(x)=(x-3)^2-5

Then convert the vertex form into standard form for the equation in the choice.

g(x)=(x-3)^2-5\\g(x)=(x^2-6x+9)-5+9\\g(x)=(x^2-6x)+4\\g(x)=x^2-6x+4

Thus, the answer is B.
