Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> represents the amount that Jennifer has
y ----> represents the amount that Matthew has
we know that
The amount that Jennifer has is greater than or equal to $34 plus three times the samount that Matthew has
The inequality that represent this situation is
we have
substitute
The solution is the interval [40,∞)
In a number line the solution is the shaded area at right of x=40 (closed point)
see the graph attached
What kind of equation is that? That don't even look like an equation.
Answer:
Step-by-step explanation:
The product of..2x + y and 5x - y +3....
= (2x + y) × (5x - y + 3)
= (10x² -2xy + 6x + 5xy -y² + 3y)
= ( 10x²- y² +3xy +6x + 3y)

Answer:
it's E
Step-by-step explanation:
(5x+y)²
You expand the bracket
it gives;
(5x + y)(5x+y)
Now, multiply 5x by 5x=25x²
multiply 5x by y= 5xy
multiply y by 5x=5xy
multiply y by y=y²
Bringing into an equation it gives;
25x²+5xy+5xy+y²
=25x²+10xy+y²
2.5*3 = 7.5 She run's 2 1/2 miles, which is equivalent to 2.5 miles, and 3 days per week, so you multiply 2.5 by 3
6.5 *2 = 13 She run's 6.5 miles per day for 2 days, again, because 6 1/2 is equivalent to 6.5 miles. Since she ran for 2 days so you multiply 6.5 by 2
13+7.5 = 20.5 miles
as for the answer, you just add the two numbers you got from Julie running
