To find the value of y when x = -0.3, substitute x = -0.3 into the equation and solve for y. The value of y is 3200.
To find the value of y when x = -0.3, we can use the given equation:
Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)
Substituting x = -0.3 into the equation, we can solve for y.
Y = 400+ 0.85(Y-0.25Y) + 300 + 200 +500 -0.1(Y-0.25Y)
Y = 1400+ 0.6375Y - 0.075Y
0.4375Y = 1400
Y = 3200

Reason
The number of gallons used is estimated to be approximately: distance/mpg = 1940/28 = 69.2857 gallons.
Each gallon costs $2.95, so the total cost is 69.2857*2.95 = 204.392815 which rounds to 204.39
Let amanda's age be x and her dad's age be y.
Amanda’s dad is twice as old as she, therefore 2x=y
The sum of their ages is 66, therefore x+y=66
x+y=66
2x=y,
substitute.
2x+x=66
3x=66
Divide.
x=22.
plug it back in, 22+y=66, y=44.
Amanda's age is 22 and her dad's age is 44.

Equation F: a = 3b + 4
Which statement describes a step that can be used to find the solution to the set of equations?
Equation F can be written as 5b + 1 = 3b + 4.
Equation F can be written as b + 1 = 3b + 4.
Equation F can be written as a = 3(a − 1) + 4.
Equation F can be written as a = 5(a − 4) + 1.
Answer:
Equation F can be written as 5b + 1 = 3b + 4
Step-by-step explanation:
A set of equations is given below:
Equation E: a = 5b + 1
Equation F: a = 3b + 4
In substitution method we solve the equation for a variable and substitute it in other equation
Given a= 5b +1
Also equation F : a= 3b+4
both equation have 'a' on the left hand side
So we substitute 5b+1 for 'a' in second equation
Substitute 5b+1 in the place of 'a' in Equation F
Equation F can be written as 5b + 1 = 3b + 4
