Answer:
1. One solution
2. Infinite solution
3. No solution
Step-by-step explanation:
1. y = -4x - 5.........eq 1
+ (y = -4x + 1)..........eq 2
---------------------
2y = -4
divide by 2
2y/2 = -4/2
y = -2
solve for x
put y in any equation
from equation 1
y = -4x - 5
-2 = -4x -5
combine the like terms
-2+5 = -4x
3 = -4x
divide by -4
3/-4 = -4x/-4
x = -0.75
One solution
2. -3x + y = 7
2x - 4y = -8
Infinite solution
3. 3x - y = 4
6x - 2y =8
No solution
-7(x^2 - 6) + 2y
x = 2 and y= -6
Plug in the numbers and solve
-7(2^2-6) + 2(-6)
-7(4 - 6) + -12
-7(-2) - 12
14 - 12

Hope this helps!
Students on the minibus = 8
students that are boys = 5
fraction of the student that are boys = ?
we can write fraction as the numerator and denominator so here the fraction of boys students is = 5/8
this fraction means and shows that there are 5 students are boys from 8 students.
