Answer:
Make it 3x+7y=15...equation 1
Anr, 5x+2y=-4...equation 2
Now use elimination or substitution method to solve
Answer:
102
Step-by-step explanation:
The first step is to find out how to find the next number in the term.
In this we can see that to get to the next number in the term we need to add 5.
The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.
But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.
The 21st term is 102.
Answer:
Point N will be located between 0 and -1.
Step-by-step explanation:
Points A and D are placed at (-4, 0) and (4, 0) on a number line.
We have to find the location of a point N which divides AD in the ratio of 3 : 4.
Coordinates of a point (x, y) which divides a segment with extreme ends at and in the ratio of m : n is given by,
x =
y =
By this formula, coordinates of the point N will be,
x =
x =
y = 0
Therefore, coordinates of the point N are .
Point N will be located between 0 and -1.
