The product of any number and 0 is zero. The expression is 1*0-0/y. 1*0 is obviously 0. 0/y is the same thing as 0 * 1/y, which is also zero. 0-0 is 0, so the answer is 0.
Given:
The inequality is
To find:
The value of x and then graph on the number line.
Solution:
We have,
Subtracting 19 from both sides, we get
It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
Answer:
Step-by-step explanation:
The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.
Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to .
So, you can count backwards once from the origin to get your x-value ⇒ and count up upwards four times from to get your y-value ⇒ .
Finally, place these in a coordinate point ⇒ .
Answer: 1m
Step-by-step explanation:
since model is 20cm, a 1:5 scale means the actual is 5x as big. since 20cm x 5 is 100 cm and 1m is 100 cm, the answer in the box should be 1.
Answer:
21 boxes of books
Step-by-step explanation:
guy= 140 lbs
each box= 40lbs elevator can only weigh up to 1010
i took 1010- 140 and got 870lbs left for the books
then i took 870 divided by 40 (to see how many boxes of books can be put on the elevator) and got 21.75
so 21 boxes could go on the elevator at a time
