Answer:

one solution: x=10

Step-by-step explanation:

The coefficients of x on each side of the equal sign are different, so the equation is not a tautology. It must have exactly one solution.

Given f(x) = 5x - 6 and g(x) = x2 - 5x + 6, find the function (f + g)(x). Use the ^ key for the exponent. Enter your answer as t

sesenic [268]

The answer is x².

f(x) = 5x - 6
g(x) = x² - 5x + 6

(f + g)(x) = f(x) + g(x)
= 5x - 6 + x² - 5x + 6
= x² + 5x - 5x + 6 - 6
= x² + 0 + 0
= x²

Express 1400 as a product of its prime factors in index form

exis [7]

Answer:

$2^3 X5^2 X7$

Step-by-step explanation:

Given the number: 1400

A number is said to be prime when it can only be divided by 1 and itself.

We can express 1400 as a product of its prime numbers by gradually decomposing it into smaller units.

$1400=14X100\\14=2X7\\100=10X10=2X5X2X5\\$Therefore:\\1400=2 X 7 X 2 X 5 X 5 X 5\\Reorganising\\1400=2 X 2 X 2 X 5 X 5 X 7\\Therefore, 1400 expressed as a product of its prime factors is:\\1400=2^3 X5^2 X7$

Answer:

x-1 = 0 or x-7 =0

x=1 or x=7

Step-by-step explanation:

(x-1) (x-7) =0

Using the zero product property

x-1 = 0 or x-7 =0

x-1+1 =0 +1 or x-7+7 =0+7

x=1 or x=7
