What are the numbers x+ y = 17 x - y= 7

X = 12 and y = 5

I found this out by starting out with x = 10 and y = 7 (because 10 + 7 equals 17), and escalating while trying out every number with both equations.

Match each function with the expression representing its inverse function.
Georgia [21]

Answer:

  • A matches with 5.
  • B matches with 3.
  • C matches with 2.
  • D matches with 6.
  • E matches with 4.
  • F matches with 1.

Step-by-step explanation:

To find the inverse of a function f(x), we let f(y)=x and then solve again for y.

For example, using g(x)=-0.5x, we will let g(y)=x, giving x=-0.5y. This means that y=-2x, and thus g^{-1}(x)=-2x.

Using similar logic, we see that:

  • A matches with 5.
  • B matches with 3.
  • C matches with 2.
  • D matches with 6.
  • E matches with 4.
  • F matches with 1.

o-na [289]
Since it’s 35% off, but there’s a 8% tax,
35 - 8 = 27%

You get a 27% discount.

69 x 0.27 = 18.63

The total cost is $18.63

Connor has a collection of dimes and quarters with a total value of $6.30. The number of dimes is 14 more than the number of qua
Anarel [89]

Connor has 14 quarters and 28 dimes.

Step-by-step explanation:

Given,

Worth of coins = $6.30 = 6.30*100 = 630 cents

We know that,

1 quarter = 25 cents

1 dime = 10 cents

Let,

Quarter = x

Dime = y

According to given statement;

25x+10y=630    Eqn 1

The number of dimes is 14 more than the number of quarters

y = x+14    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

25x+10(x+14)=630\\25x+10x+140=630\\35x=630-140\\35x=490

Dividing both sides by 35

\frac{35x}{35}=\frac{490}{35}\\x=14

Putting x=14 in Eqn 2

y=14+14\\y=28

Connor has 14 quarters and 28 dimes.
