The quadratic equation that represents the product is .
We are given in the question that the product of a number and 3 more than twice that number is at most 152.
It is also given that the smaller number is represented by the expression n.
Hence, according to the question, the larger number will be:-
2n+3
The product of the two numbers will be :-
n(2n+3)
It is given that the product of the two numbers is at most 152.
Hence,
n(2n + 3) ≤ 152
Hence, the quadratic inequality comes out to be:-
Taking 152 to the left hand side , we get the quadratic inequality,

Answer:
y = 2/5x + 24/5
*View graph to see the lines*
Step-by-step explanation:
y = 2/5x - 1/2
Parrel lines have the same slope
y = mx + b
y = 2/5x + b
2 = 2/5(-7) + b
2 = -14/5 +b
5(2 = -14/5 +b)
10 = -14 + 5b
+14 +14
24 = 5b
/5 /5
24/5 = b
y = 2/5x + 24/5
Hope this helps!
Answer:
If you look over the steps you can see that until 4x + x + 3 = 18, evertything is dandy. But the step after that 4x + x =21 seems a bit fishy.
Think about it they subtract 3 from both sides so the first side is correct
4x + x, but they added 3 to the other side:
not
4x+x = 21
Then we solve for 4x + x = 15
To solve for y we use :
y = x+3
y = 3+3 = 6
so (3,6) is the right answer
