Answer:
x= 3/8 or 0.375
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x+−12=3x+1
Step 2: Subtract 3x from both sides.
7x+−12−3x=3x+1−3x
4x+−12=1
Step 3: Add 1/2 to both sides.
4x+−12+12=1+12
4x=32
Step 4: Divide both sides by 4.
4x4=324
x=38
Remark
There are two formulas for doing this. I'll use the one that does not involve the slope. I think it will be easier for you to understand.
Step One
Decide which point is (x1,y1)
Since point P is 2/5 the way up from point A, we will call (x1,y1) point A
Step Two
Write the givens.
Point(A) = (-2,-3)
Point(B) = (3,2)
Step Three
Write the formula
x1 + ratio*(x2 - x1), y1 + ratio(y2 - y1)
Sub and solve.
-2 + 2/5 *(3 - - 2) , -3 + 2/5*(2 - -3)
-2 + 2/5(5) , - 3 + 2
-2 + 2 , - 1
P = (0 , - 1) <<<<<< Answer

Answer: 1/4
Step-by-step explanation: When multiplying two fractions together, we multiply across the numerators and we also multiply across the denominators.
