Let 1st number be = x
Thus second number = x - 4

Now

(x) + (x - 4) = 72
2x - 4 = 72
2x = 76
x = 38

1st number is 38 thus 2nd number is (38 - 4) = 34

Solve the quadratic equation below<br><br> x2-64=0
Montano1993 [528]

Answer:

x=32

Step-by-step explanation:

first, you add 64 to both sides and you have:    x2=64

second, you divide 2 on both sides to get x by itself, so 64 divided by 2 is 32

A business uses straight-line depreciation to determine the value y of an automobile over a 5-year period. Suppose the original
Elena-2011 [213]

For this problem. it is found that:

a) The automobile has depreciated 75% in 5 years.

b) The value of the automobile was reduced by $10,500 in five years.

c) The linear function is: s(t) = 14,500 - 2,100t.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = ax + b

In which:

  • a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

From the problem, we have that:

a) The automobile has depreciated 75% in 5 years, as 4000/14500 = 0.25, and 100% - 25% = 75%.

b) The value of the automobile was reduced by $10,500 in five years, as 14500 - 4000 = $10,500.

For the linear function, we have that:

  • The initial value is b = 14500.
  • The slope is of a = -10500/5 = -2100.

Hence the linear function is: s(t) = 14,500 - 2,100t.

True Or False?

Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
