If the point (2,-3), then it must satisfy both inequalities.
Let's replace it with the first one
As you can observe, the test point satisfies the first inequality.
Let's evaluate the second one
The test point doesn't satisfy the second inequality.
<h2>Hence, the test point is not a solution to the given system because it doesn't satisfy both inequalities.</h2>
Answer:Total hours worked by John in his garden=3 5/8 hours.
Step-by-step explanation:
Time spent planting =1 1 /2 hours planting
Time spent trimming = 2 1 /8 hours
Total hours worked by John in his garden= Time spent planting +Time spent trimming
=1 1/2 + 2 1/8( add whole numbers together and fractions together)
= 3 4+1 /8
3 5/8 hours.
BECAUSE
4(2x)= 8x
4(1)= 4
SO
4+8x= 4(2x+1)
Answer:
It would be 70
Step-by-step explanation:
First step: Divide 156 by 2
156 / 2 = 78
Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).
78 - 8 = 70 Desktops
78 + 8 = 86 Laptops
Hope this helps :)
Whenever a quadratic equation is in the form
(i.e. the leading terms is 1), you can solve it by looking for two numbers that give 
when summed and 
when multiplied.
So, in your case,
So, we're looking for two numbers 
such that:
you can clearly check that these numbers are 3 and 4.
