Answer:
I. C
II. A, D
III. B
Lines that coincide have infinite solutions, and parallel lines have no solutions.
Step-by-step explanation:
3. To solve this equation, look at the slopes of the equation. The equations are in y=mx+b form. m is equal to the slope.
Equations with different slopes will have one solution, meaning that the lines will intersect once.
Equations with the same slope will either have no solutions or infinite solutions. <u>If the equations are the exact same</u>, it will have infinite solutions, meaning that the line "intersects" itself in infinite places since its basically one line right on top of another. <u>If the equations have different y-intercepts</u>, it will have no solutions because the lines are going at the same angle, are parallel and will never intersect.
This means that A and D have one solution, B has infinite solutions, and C has no solutions.
4. Lines that coincide have infinite solutions, and parallel lines have no solutions.
Answer:
let total no. of red marbles be x and blue marbles be y.
then according to first case
x + y =36
or,x=36 -y.....(i)
in case second
x/5 =y/4
or,x=5y/4......(ii)
then from equation i and ii, we get
36-y = 5y/4
or, (36-y)4 = 5y
or, 144 -4y =5y
or, 144 = 5y + 4y
or, 144 = 9y
or, 144/9 =y
or, y = 16
again x = 36 -y
here , y =16
so,
x= 36 -16
x= 20.
hence total no. of red marbles is 20 and blue marbles is 16 .
If Carls removes 1 blue marble from bag, there will be 15 marbles in the bag,
20÷5 is not equal to 15 ÷3 .
correct ratio of red and blue marbles is 20÷15=
4/3.
Answer:
it' 1 because from the left 5 or more raise the score 4 or less let it rest and then you get rid of the decimal and number to the right of it.
idk if it makes sense sooo.....
Answer and Explanation
<h2>0</h2>
<em>This is because they are both the same opposite number, and you are adding.</em>
But, if it was, 
then it would be 
or 
.
<em>So, the answer is 0.</em>
