The value of y-x is (-3)
<u>Solution:</u>
Given: The value of x-y=3
To find: The value of y-x
Let's multiply the equation (1) by (- 1) on both sides,
On multiplying the sign,
The above equation can also be written as,
<u>Multiplication of signs:</u>
In simpler terms, when we multiply two integers with the same signs, the result is always positive and when we multiply two integers with different signs, the result is always negative.
Answer:
-8/17
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-75-(-51))/(31-(-20))
m=(-75+51)/(31+20)
m=-24/51
m=-8/17
To solve the exercirses which are shown in the figure attached, you must follow the proccedure below:
7) (x)=x³-6x²+8x
(x)=x(x³-6x²+8)
(x)=(x-4)(x-2)x
The lenght is: x
The height is= (x-4)
8) √(2x+8)-6=4
1. You need to clear the variable "x". Then:
√(2x+8)=4+6
√(2x+8)=10
(√2x+8)²=10²
2x+8=100
2x=100-8
x=92/2
x=46
9) l4x+3l=9+2x
1. To solve the left member, you must evaluate two cases: it could be positive,or negative. Then:
2. Negative:
l4x+3l=9+2x
-4x-3=9+2x
-4x-2x=9+3
-6x=12
x=12/-6
x=-2
3. Positive:
l4x+3l=9+2x
4x+3=9+2x
4x-2x=9-3
2x=6
x=6/2
x=3
Answer:
Step-by-step explanation:
If 4 are $2.00 , then x3 to get 12 light bulbs and 2x3=6 so it's $6.00
