Answer:
Explanation:
1.
x^2 - 10x + 24
= (x - 6)(x - 4)
2.
x^2 - 12x + 27
= (x - 9)(x - 3)
3.
x^2 - 13x + 36
= (x - 9)(x - 4)
4.
x^2 - 5x - 14
= (x - 7)(x + 2)
5.
x^2 + x - 20
= (x + 5)(x - 4)
6.
x^2 - 3x - 40
= (x - 8)(x + 5)
7.
x^2 + 2x - 48
= (x - 8)(x + 6)
8.
x^2 + 10x - 24
= (x - 2)(x + 12)
9.
x^2 - 7x - 44
= (x - 11)(x + 4)
10.
x^2 + x - 2
= (x + 2)(x - 1)
11.
x^2 + 2x + 1
= (x + 1)(x + 1)
12.
x^2 - x - 6
= (x - 3)(x + 2)
2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Put a dot on your y-axis at -4 (the one going up and down), from there go up two, and over one. your second dog should be at (1,-2). connect your dots and that’s your graphed equation !
