Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of hours landscaping
y ----> the number of hours clearing tables
we know that
she can work a maximum of 12 total
so
----> inequality A
she must earn a minimum of $120
so
----> inequality B
Solve the system of inequalities by graphing
The solution is the triangular shaded area
see the attached figure
Remember that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (the ordered pair lie in the shaded area of the solution set)
One possible solution is the point (10,1)
The point (10,1) lie in the shaded area
That means
The number of hours landscaping is 10 and the number of hours clearing tables is 1
55-24=31
31/55=56%
55 > 31 so decreased
Percent of change is decrease 56%
Answer:
A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.
It factors to (a+b)(a-b).
Step-by-step explanation:
A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.
A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.
It factors to (a+b)(a-b).
<span>7x+15=2x+19
Subtract 2x from both sides
5x+15=19
Subtract 15 from both sides
5x=4
Divide 5 on both sides
Final Answer: C.) x= 4/5</span>
45 degrees
if two angles compliment each other they add up to ninety degrees or a straight angle. since it is half as large, divide ninety by two to get forty-five
