Answer: 60
Step-by-step explanation:
ball =x
bat = y
x + y = 90
and
equation II is
3 x + 2 y =210
By multiplying by 3 to equation I both sides
we get equation III as
3( x + y) = 3 ( 90 )
3x + 3y =270 III
subtract II and III
we get 3x+3y=270
- 3x+2y=210
--------------------------
0+y= 60
y =60
cost of bat is y ie = 60
and cost of ball ,is
let put value of y in equation I
x+60=90
x=90-60
x=30
cost of ball is 30
When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
The determinant is 3×4 - 1×(-2) = 14.

Answer:
The y-intercept of line is (-3)
Step-by-step explanation:
Given equation of line is given by y=
The general equation of line is given y=mx+c
Where, m= slope of line
c= y-intercept of line
On comparing both the equation.
c=(-3)
OR
y-intercept is when x=0,
therefore,
y=
y=
y=(-3)
Thus, y-intercept of line is (-3)
