Answer:
-3/2.
Step-by-step explanation:
0.5 = 1/2
-1.5 = -1 1/2
= -3/2.
Answer:

3.42500 feet (3 feet 53⁄32 inches)
Step-by-step explanation:
((1 4/5) feet) + ((1 5/8) feet) =
3.42500 feet (3 feet 53⁄32 inches)
Answer:
y = x - 7
Step-by-step explanation:
Parallel lines have the same gradient in this case 1 is the gradient.
Using the point (8,1) we can form our own equation.
1 will be y, 1 will be m, 8 will be x
All we have to do is find C in order to form the equation <em>y</em><em>=</em><em>mx</em><em>+</em><em>c</em>
1 = 1(8) + c
1 = 8 + c
C = - 7
Therefore;
<u>y = x - 7</u>
To factorise this quadratic, you need to find two numbers that add together to give -8 but also multiply to give 15. These two numbers can be identified as -3 and -5 as -3-5=-8 and -3×-5=15. Therefore, the factorised form is (x-3)(x-5). To find the solutions, write (x-3)(x-5)=0. Deal with each bracket individually:
x-3=0
x=3
x-5=0
x=5
So the two solutions are 3 and 5.
