Answer:

No solutions: 7−5+3x−1= 3x + 7

One solution: 7−5+3x−1= 2x + 4

Infinitely Many Solutions  7−5+3x−1= 3x + 1

Step-by-step explanation:

No solutions means it results in no x and a false statement like 3 = 0.

One solution means it results in x = a number.

Infinite solutions means its results in no x and in a true statement like 3=3.

  • So to get No solutions: 7−5+3x−1= 3x + 7

This will eliminate the x and result in 1 = 7 which is false.

  • One solution: 7−5+3x−1= 2x + 4

This will result in x= 3

  • Infinitely Many Solutions  7−5+3x−1= 3x + 1

This will eliminate the x and result in 1 = 1 which is true.

Write in logarithmic form.<br> 729 = 9^3
kolezko [41]

Answer:

Step-by-step explanation:

729 = 9³

by definition

a = b^{c} can be written as log_{b} a = c

by the same reasoning

729 = 9^{3} can be written as log_{9} 729 = 3

Murtha has decided to start a pebble collection. She collects one pebble the first day and two pebbles on the second day. On eac
Musya8 [376]

Answer:

78

Step-by-step explanation:

Given that:

First day (a) = 1

1 more pebble every subsequent day than the previous day

Tn = a + (n - 1)d

d = common difference ; difference between pebbles in two successive days = 1

n = nth day

At the end of the 12th day;

Tn = a + (n - 1)d

T(12) = 1 + (12 - 1) 1

T(12) = 1 + 11

T(12) = 12

Appling the sun if arithmetic progression formula : Sum of AP:

n/2 (a + Tn)

n = number of terms

12/2 (1 + 12)

6(13)

= 78

Irrational conjugate theorem
podryga [215]

Answer:

The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.

Step-by-step explanation:

The irrational conjugate theorem states that if a polynomial equation has a root (a + √b), then we can say that the conjugate of (a + √b), i.e. (a - √b) will also be another root of the polynomial.

For example, if we consider a quadratic equation x² + 6x + 1 = 0, then two of its roots are - 3 + √8 and - 3 - √8 and they are conjugate of each other. (Answer)
