Answer:
Sajini = 200
Drea = 225
Step-by-step explanation:
d = amount Drea earned
s = amount Sajini earned
Together they earned 425
d+s =425
d = s+25
The system of equations
d+s =425
d = s+25
I will use substitution to solve
Substitute d= s+25 into the first equation
d+s =425
(s+25) + s = 425
Combine like terms
2s+25 =425
Subtract 25 from each side
2s+25-25 =425-25
2s = 400
Divide by 2
2s/2 =400/2
s =200
Sajini = 200
Now we need to find d
d = s+25
d = 200 + 25
d = 225
Drea = 225

Answer: y = 3/8 x + 17/8
Step-by-step explanation:
Point-Slope Form: y - y₁ = m (x- x₁) Slope: Change in y/Change in x
(-3,1) and (5,4) are the coordinates given. 4 - 1 / 5 - ( - 3)
Slope Intercept Form: y =mx + b <em> </em><em><u>3 / 8 </u></em> <em>( - ) ( - ) = +</em>
Write in point slope: | Using (-3, 1) |
y - 1 = 3/8 ( x - ( -3 ) )
y - 1 = 3/8 ( x + 3)
y - 1 = 3/8 <em>x</em> + 9/8
y - 8/8 = 3/8 x + 9/8
y = 3/8 x + 17/8
(1/2)/(1/3) is the answer for you sir! I think...
