Answer:

x = 3

x = 2

 x= ± √ -1

Step-by-step explanation:

 ((((x^4)-(5•(x^3)))+7x^2)-5x)+6  = 0

 ((((x^4) -  5x^3) +  7x^2) -  5x) +  6  = 0

Dividing :  x^4-5x^3+7x^2-5x+6  

                             ("Dividend")

By         :    x-3    ("Divisor")

Quotient :  x^3-2x^2+x-2  Remainder:  0

Dividing :  x^3-2x^2+x-2  

                             ("Dividend")

By         :    x-2    ("Divisor")

Quotient :  x^2+1  Remainder:  0

(x^2 + 1) • (x - 2) • (x - 3)  = 0

x^2+1 = 0

x^2 = -1

x  =  ± √ -1

x-2 = 0

x = 2

x-3 = 0

x = 3

svet-max [94.6K]

Answer:

- 38

Step-by-step explanation:

Here in this question, we have to simplify a certain numeric term to get a simple answer.

The expression is ( - 6 times + 3 ) + ( 5 times - 4 )

= - ( 6 times 3 ) + (5 times - 4)

= - ( 6 × 3 ) - ( 5 × 4 )

= - 18 - 20

= - 38 (Answer)

german

Answer:

The cost of

Regular baskets = x = $20

Deluxe baskets = y = $42

Step-by-step explanation:

The drama club is selling gift baskets to raise money for new costumes.

Let us represent:

The cost of

Regular baskets = x

Deluxe baskets = y

During the fall play, they sold a combined 18 regular gift baskets and 19 deluxe gift baskets, earning a total of $1,158.

Hence:

18x + 19y = 1158....... Equation 1

During the spring musical, they sold 15 regular gift baskets and 12 deluxe gift baskets, earning a total of $804.

15x + 12y = 804...... Equation 2

Combining them two Equations

18x + 19y = 1158....... Equation 1

15x + 12y = 804...... Equation 2

Multiplying Equation 1 by 15 and Equation 2 by 18 to Eliminate x

270x + 285y = 17370..... Equation 3

270x + 216y = 14472...... Equation 4

We Subtract Equation 4 from Equation 3.

69y = 2898

y = 2898/69

y = $42

Solving for x

18x + 19y = 1158....... Equation 1

18x + 19 × 42 = 1158

18x + 798 = 1158

18x = 1158 - 798

18x = 360

x = 360/18

x = $20

Therefore,

The cost of

Regular baskets = x = $20

Deluxe baskets = y = $42

What is the y-intercept of the following equation. 3x-2y=6
tester [92]
3x-2y=6

1) <span>Add -3x to both sides.
</span><span><span>  3x</span>−<span>2y</span></span>=<span>6
</span>+3x      +3x
-----------------
<span>−<span>2y</span></span>=<span><span>−<span>3x</span></span>+<span>6
</span></span><span>
2) Divide both sides by -2.
</span>\frac{-2y}{-2} = \frac{−3x+6}{-2}

y=<span><span><span>32</span>x</span>−<span>3
</span></span>
3) Substitute the y with the equation
3x-2(32x-3)=6
3x-64x+6=6

4) Combine like terms
3x-64x+6=6
-61x+6=6

5) Subtract 6 from each side of the equation
-61x+6=6
        -6 -6        (+6-5 gets crossed out)
--------------
-61x=0

6) Divide both sides by -61
\frac{-61x}{-61} =  \frac{0}{-61} 
x=0

============================================================

Now that you've got you x intercept, use the x value and substitute it into the
y=32x−3

y=32(0)-3
y=0-3
y=-3

(0,-3)
