Easy peasy
sub random points for x and solve for y
or solve for y and sum points for x and get y values
some easy points that work most of the time
sup
x=0
y=0
if x=0
0-4y=-18
4y=18
y=9/2
y=4.5
(0,4.5) is one point
if y=0
x-4(0)=-18
x=-18
(-18,0) is aonther
another is
(-5,2)
3 points are
(0,4.5)
(-18,0)
(-5,2)
Santosh's cousin is 15 years old because 49-4=45. Divide 45 by 3 and the quotient is 15. To check: 15 times 3= 45. Add 4 and the sum is 49.
Answer:
x = -8 and x =1
Step-by-step explanation:
Given the equation
X^2+7x=8
X^2+7x-8 = 0
Factorize
x^2 - x +8x - 8 = 0
x(x-1)+8(x-1) = 0
(x+8)(x-1) = 0
x+8 = 0 and x-1 = 0
x = 0-8 and x = 0+1
x = -8 and 1
Hence the required solution is x = -8 and x =1
