Answer:9/6 or simplified 1 1/2
Step-by-step explanation:
<h2>
The "option d:
+ 13x + 12" is a trinomial with a constant term.</h2>
Step-by-step explanation:
To check options:
a: x + 4y
Here, the coefficient of x = 1 and the coefficient of y = 4
b: 
Here, the coefficient of
= 1
c:
+ 3
+ 2y
Here, the coefficient of
= 1, the coefficient of
= 4 and the coefficient of y = 2
d:
+ 13x + 12
Here, the coefficient of
= 1, the coefficient of x = 13 and
constant term = 12
Thus, the "option d)
+ 13x + 12" is a trinomial with a constant term.
Answer:
Option (b) is correct.
The solution of the quadratic equation
is -7 and 3
Step-by-step explanation:
Consider the given quadratic equation
This can be rewritten as,
We can solve the quadratic equation using middle term splitting method,
4x can be written as 7x-3x , we get,
Taking terms common, we get,
Thus,
Thus, we get (x-3)= 0 or (x+7)= 0
this gives x = 3 or x = -7
Thus, the solution of the quadratic equation
is -7 and 3
Standard form is ax+by=c where a,b, and c are integers and a is usually positive
so
first find slope
get into form y=mx+b where m is slope
so
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
points (-1,5) and (1,2)
slope is (2-5)/(1-(-1))=-3/(1+1)=-3/2
y=-3/2x+b
find b
sub a point
(1,2)
2=-3/2(1)+b
2=-3/2+b
4/2=-3/2+b
7/2=b
y=-3/2x+7/2
add 3/2 both sides
3/2x+y=7/2
times 2 both sides
3x+2y=7 is standard form
Answer:
he got 8 books free and now has 24 books total
Step-by-step explanation:
16/2=8
that would be the answer for how many books he got for free because if there is a box of 16 books and for every2 books you get one free then you would divide 16 and 2 and get 8 then
16+8=24
add the number of books he got for free with the original 16 books he already had and get 24 total books.
