Solve the following equation for x: 2x + 5y = 8.

1 answer:

4 0

The answer would be the bottom one because it would be 5 over negative 2x so it would be a negative fraction and then the 8 is positive and divide that by two and you get 4

vfiekz [6]

We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>

Outside temperature over a day can be modeled as a sinusoidal function. suppose you know the temperature is 75 degrees at midnig

antoniya [11.8K]

We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write

... d = 75-12sin(π·t/12)
