scZoUnD [109]3 years ago
3 0

Answer:

63 and 72

Step-by-step explanation:

Sum the parts of the ratio, 7 + 8 = 15 parts

Divide the sum by 15 to find the value of one part of the ratio

135 ÷ 15 = 9 ← value of 1 part of the ratio, thus

7 parts = 7 × 9 = 63

8 parts = 8 × 9 = 72

The numbers are 63 and 72

40 points!!<br> What's the equation for this ellipse?
Ostrovityanka [42]

Answer:

  (x +5)²/4 +(y +8)²/36 = 1

Step-by-step explanation:

The equation of an ellipse with center (h, k) and semi-axes "a" and "b" (where "a" is in the x-direction and "b" is in the y-direction) can be written as ...

((x -h)/a)² +((y -k)/b)² = 1

Here, the center is at (h, k) = (-5, -8), and the semi-minor axis is a=2, while the semi-major axis is b=6.

The equation can be written as ...

  ((x +5)/2)² +((y +8)/6)² = 1

More conventionally, it is written ...

  (x +5)²/4 +(y +8)²/36 = 1

Step-by-step explanation:

we are asked to subtract 7x-9 from 2x^2-11

so, 2x^2-11-(7x-9)\\=2x^2-11-7x+9\\=2x^2-7x-2.

Hence the desired result is:  2x^2-7x-2.
