Mr lim had just enough money to buy 6 similar lamps. However, he bought 3 such lamps and had $950 left. How much money did mr li
Artyom0805 [142]

Let the cost of a lamp = x

6 lamps would cost 6x

He bought 3 lamps at 3x plus Thad 950 left.

3 lamps plus the 950

Would be the same amount as 6 lamps:

Set up an equation and solve for x:

3x + 950 = 6x

Subtract 3x from both sides:

950 = 3x

Divide both sides by 3:

X = 316.67

Each lamp was $316.67

Multiply the price of a lamp by 6:

316.67 x 6 = 1900

He had $1900

1. If x³ +3x²-4=0 has x=-2 as a root (zero), find the other two roots.
castortr0y [4]

Answer:

1 and -2 (has a multiplicity of 2)

Step-by-step explanation:

so since x=-2 is a root then (x+2) is a factor of the polynomial. This means you can divide the polynomial by (x+2) by using synthetic or long division. So for this example I'll using synthetic division which is much more simple than long division

-2 | 1   3    0   -4

         -2   -2    4

     1    1    -2   0

(x+2)(x²+x-2)

Now you can factor the quadratic into

(x+2)(x-1)

x+2 = 0

x = - 2

x-1 =0

x = 1

Two times the quantity of eight times a number plus two is equal to three the quantity of two times the same number minus seven
Effectus [21]

The unknown number is - 2.5

Let the number = n

The equation will be formed as follows;

  • eight times a number plus two = 8n + 2
  • Two times the quantity of eight times a number plus two = 2(8n + 2)
  • two times the same number minus seven = 2n - 7
  • three the quantity of two times the same number minus seven = 3(2n-7)

Our final equation becomes;

2(8n + 2) = 3(2n-7)

Simplify as follow, to determine the unknown number;

16n + 4 = 6n - 21

16n - 6n = -25

10n = -25

n = -2.5

Thus, the unknown number is - 2.5
