Write a proof. Given x = 2 = 3 (x - 4) Prove x = 5

Mathematics
1 answer:
Galina-37 [17]2 years ago
6 0

Step-by-step explanation:

The equation in the question is false.

x - 2 = 3(x - 4)

x - 2 = 3x - 12

3x - x = 12 - 2

2x = 10

x = 10 \div 2

x = 5

Find zeros and y intercept of each function algebraically f(x)=x^3-10x^2+24x
monitta

Answer:

The zeros are 0, 4, 6.

The y-intercept is 0.

Step-by-step explanation:

f(x) = x^3 - 10x^2 + 24x

x^3 - 10x^2 + 24x = 0

x(x^2 - 10x + 24) = 0

x(x - 4)(x - 6) = 0

x = 0 or x - 4 = 0 or x - 6 = 0

x = 0 or x = 4 or x = 6

y-intercept:

Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.

You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).

Let x = 0.

f(0) = 0^3 - 10(0^2) + 24(0)

f(0) = 0

y-intercept: 0
