Answer:
Step-by-step explanation:
It is vital to first find the gradient/ slope between the points
let us use the point (6,1) to find the value of c
y=mx+c
1=1(6)+c
1-6=c
∴c=-5
the equation is given by
y=x-5
Answer: n= −3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8(4n+3)=−72
(8)(4n)+(8)(3)=−72(Distribute)
32n+24=−72
Step 2: Subtract 24 from both sides.
32n+24−24=−72−24
32n=−96
Step 3: Divide both sides by 32.
32n/32 = −96/32
n=−3

Answer: 3(2)^2 + 4(3)^2
Step-by-step explanation:
First do what is replacing the variables by changing X to 2 and Y to -3
3(2)^2 + 4(-3)^2 = 3(4) + 4(9) = 12 + 36 = 48
Answer:
