The greater of two consecutive integers is seven less than one-third the smaller integer. Find the integers
ikadub [295]

Answer:

Step-by-step explanation:consecutive integers are represented by x, x+1 ,  so for this problem the greater one is represented by x + 1.

Now you need to translate the problem.  the greater is  seven less than 1/3 the smaller

--->  x + 1 = (1/3)*x - 7 --->  now solve for x (the smaller) and x+1  (the greater)

***hint:  to get rid of fractions in an equation you can always multiply EVERYTHING by the denominator , 3 in this case

Consider the quadratic equation x2 + 2x - 35 = 0. Solve by factoring and using the zero-product property.
Morgarella [4.7K]

Answer:

x = -7

x = 5

Step-by-step explanation:

The standard form of quadratic equations is

Ax^2 + Bx + C = 0

The factors need to multiply together to be C and add together to be B.

The two numbers that will multiply together to be -35 and add together to be 2 are -5 & 7.

The factor pairs are (x+7)(x-5). Zero product property means we set each of those factor pairs = 0 and solve.

x + 7 = 0

-7 -7 Subtract 7 from each side to solve

x = -7

x - 5 = 0

+5 +5 Add 5 to each side to solve

x = 5
