Answer:
y-4 = -2(x+1)
Step-by-step explanation:
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You have m = -2 and (h, k) = (-1, 4). Putting these numbers into the above form gives ...
y -4 = -2(x +1)
Part a: 30+10d That is your equation. 30 for the start and 10 more for each additional day.
Part b: So there are 4 additional days. Let's fill in the equation and solve.
30+10*4
30+40
$70
The answer is $70
Answer:


Step-by-step explanation:
Lets call

equation 1

equation 2
using equation 2, we would make y the subject of the formula as it would be easier

This would now be called our equation 3
Now the next step is to substitute equation 3 in equation 1





Divide both sides by 27

Substitute the value of x in equation 2





Answer:
2
Step-by-step explanation:
you add 1 to 1 and that gives you 2
Hi there!
The answer is


Additional note:
To find the value of x, we only need to multiply both sides of the equation by 4
