37x-12.38 would be how to write this
xAnswer:
-10 -8 -6 -4
Step-by-step explanation:
The numbers are
first =x
second= x+2
third=x+4
4th= x+6
2(x + (x+4)) = 3(x+6)-20
4x+8 = 3x+18–20
4x-3x=18–20–8
x=-10
So the numbers are -10, -8, -6, -4
first 2nd 3rd 4th
Check:
2( -10-6) = 3(-4) -20
2(-16) = -12-20
-32 = -32
Answer:
B: 43.3
Step-by-step explanation:
Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)
point slope formula:
(y₂ - y₁) = m(x₂ - x₁)
Then we substitute any of the two set of coordinates to find c, the y - intercept.
So the line has a gradient of m and y - intercept of c
