Answer:
x = 6
Step-by-step explanation:
First find the gradient,
Since this line has no gradient, it means that it's a horizontal or vertical line. We cannot substitute in the values because the gradient is 0 so this line will only be x = 6
Answer:
-27
Step-by-step explanation:
a = 7 and c = -4
- a + 5 c
- ( 7 ) + 5 ( - 4 )
- 7 - 20
- 27
Answer:
Question 9: Variables: (smallest) s, q, r (largest)
Question 10: 5 whole numbers (7, 8, 9, 10, and 11)
Step-by-step explanation:
For question nine, there are two given statements... s=q-2 and q<r. Say we plug in 10000 (a really big #) in for q, then we would get s=9998 and r>10000. This way, we can see that s would be the smallest, then q, and r is the largest. <em>(q<r can be written as r>q)</em>

For question 10, it states 
. This can be split into 
and 
. When x is 12 in the first equation then 
and when x is 6 in the second equation 
(0.5 is also 
). Therefore, x must be a whole number less than 12 and greater than 6, and it cannot be either 12 or 6. Whole numbers between 6 and 12 are 7, 8, 9, 10, and 11 or 5 whole numbers.
Answer:
5/-3
Step-by-step explanation:
The slope formula is rise/run.
If you graph this, the two points make a line that slopes downwards. The higher point is in the negative axis, which means that the run will be negative.
you rise up 15 points from the first point (1,-6) to get to the same level as the second point. (-8,9). This is your rise.
You go over to the other point, this is your run. The run is -9.
15/-9
we can simplify this fraction.
5/-3 is your final answer.
