$3.60, 5 x 2 = 10. So 1.80 x 2 = 3.60
Answer:

Step-by-step explanation:
Given:
Two points on a line are given as:
(0, 1) and (2, -2)
We know that the slope of a line passing through points
is given as:

Plug in
. This gives,

The equation of a line with slope 'm' and points
is given as:

Now, on plugging in the second point
we get:

Therefore, the first option is correct which is given as:

Yeah you answered it correctly
To get the result we can use knowledge that reading is 2 times longer than HW.
To find this value we just have to multiply 42 times 2 so
40*2=80
Its 1 hour and 20 min - its the result
Answer:
(x−5)(x+3)
Step-by-step explanation:
To factorise, we firstly need two brackets, each containing an x.
(x)(x)
This creates the x2 term.
Now we need to get the rest of the terms. To do this, we need two factors of −15 which will add/subtract to give us +2
The two factors that do this are −3 and 5, as −3+5=2
∴(x−3)(x+5)
