****PLEASE HELP**** Meghan spends 25% more each year for auto insurance than Scott, and together they spend $1237.50 per year. H
s344n2d4d5 [400]

Answer: Meghan spent $687.5 per year.

Step-by-step explanation:

Let x represent the amount of money that Scott spends per year for auto insurance.

Meghan spends 25% more each year for auto insurance than Scott. The value of 25% of the amount that Scott spends per year is

25/100 × x = 0.25 × x = 0.25x

Therefore, the amount that Meghan spends would be

x + 0.25x = 1.25x

If the amount that they spent together is $1237.50 per year, it means that

x + 1.25x = 1237.5

2.25x = 1237.5

x = 1237.5/2.25

x = 550

The amount that Meghan spent per year would be

1.25 × 550 = 687.5

For which equation will f(-2)= -6?
Mila [183]

Answer:

C. f(x)=4x^3+6x^2-x

Step-by-step explanation:

Lets plug in -2 into each of these equation to see which one gives us the solution of -6

A. f(x)=x^3+x

f(-2)=(-2)^3+(-2)\\\\f(-2)=-8-2\\\\f(-2)=-10

B. f(x)=x^4-5x

f(-2)=(-2)^4-5(-2)\\\\f(-2)=16+10\\\\f(-2)=26

C. f(x)=4x^3+6x^2-x

f(-2)=4(-2)^3+6(-2)^2-(-2) \\\\f(-2)=4(-8)+6(4)+2\\\\f(-2)=-32+24+2\\\\f(-2)=-6

D. f(x)=-3x^3-4x^2+4x

f(-2)=-3(-2)^3-4(-2)^2+4(-2)\\\\f(-2)=-3(-8)-4(4)-8\\\\f(-2)=24-16-8\\\\f(-2)=0

As we can see, function C was the only one that gave us the value of -6, so that is our answer.

Algebra 1 help please!
Vsevolod [243]

Answer:

x=46 and y=45

Step-by-step explanation:

To solve this, you must set up a system of equations. The first sentence says that there are two numbers and that their sum is 91, so your first equation is x+y=91. For the next equation, it says that the difference of those same numbers is 1, which means that the equation is x-y=1. Now, putting those two together for the system of equations, it's easiest to add them. The result will be 2x=92 which when simplified gives you the value of x. Taking the value of x, you can substitute in the second equation to find the value of y.

Hope this helped!
