Greg was adding numbers on a number line. He started on –5 and then he added –8. Greg wrote that the answer was +13. Is Greg's answer reasonable?
A.
No, it is not reasonable because –5 + –8 = –13.
B.
Yes, it is reasonable because –5 + –8 = +13.
C.
No, it is not reasonable because if you add two numbers you will get a number that is greater than either of the two numbers.

The formula for point slope form is:
where
m=slope
now lets input the information that we know into the equation. We know the slope is 6. Our known x coordinate is 7, and our known y coordinate is 4.
y-4=6(x-7)
we are given that slope=6
subsiutte
y=6x+b
we are given the point (7,4)
(x,y)
so x=7
y=4 is one solution
subsitutute
4=6(7)+b
4=42+b
subtract 42 from both sides
-40=b
the equation is y=6x-40

Step-by-step explanation:
The shaded area is a trapezium.
Therefore, the rule for its area is base1+base2/2xh
base1=6
base2=14
height = 13
Therefore, 6+14/2 x 13
= 130

Answer:
Option C.
Step-by-step explanation:
First, let's define the transformations used here:
We can see that the red graph is shifted horizontally to the right, and that is reflected across the x-axis:
Horizontal shift:
For a general function f(x) an horizontal shift of N units is written as:
g(x) = f(x + N)
where:
If N > 0, the shift is to the left
if N < 0 , the shift is to the right.
Reflection across the x-axis.
For a function f(x), a reflection across the x-axis is just written as:
g(x) = -f(x)
So, if here we have a reflection across the x-axis and a horizontal shift of one unit to the right, we would write the equation for the red graph as:
g(x) = -f(x) (only for the reflection)
g(x) = -f(x - 1) (for the reflection and the shift)
Then the graph of the red function is:
y = -f(x - 1)
We can rewrite this as:
y = -1*f(x - 1)
dividing both sides by -1 we get:
y/-1 = f(x - 1)
This is what we can see in option C, so the correct option is C.
