Suppose that f(x) = 7x-6 and g(x) = - 4x +5. Solve f(x) = 0​

Answers

put the value of f(x) = 0

f(0) = 7(0)-6

=0-6

= -6

Step-by-step explanation:

f(x)= 7x - 6

f(x) = 0

7x - 6 = 0

7x = 6

x = 6/7 ? (I think you need to solve for x)

Actually Welcome to the Concept of the Quadratic Equations,

Here, we just use the Quadratic formula to get the roots, that is values of X, since it is an degree 2 variable, so it will have Pair of roots,

x = -b +- underoot b^2-4ac/2a

Hence, answer is +- √7

Given :-

[tex] \bullet \: 3 {x}^{2} + 7 = 28[/tex]

To Find :-

Solution of x.

Solution :-

[tex] \longrightarrow3 {x}^{2} + 7 = 28[/tex]

[tex] \longrightarrow3 {x}^{2} = 28 - 7[/tex]

Inez and Joel work at a store that sells
cell phones. Inez worked for 7 hours
and 23 minutes. Joel worked for
4 hours and 51 minutes. How much
longer did Inez work than Joel?

2 hours 32 minutes

12 hours 14 minutes

3 hours 28 minutes

3 hours 32 minutes

Answers

Answer:

2 hrs and 32 mins

Step-by-step explanation:

Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.

Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!

Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.

Step 4. But because we used a negative number we have to subtract another hour from our time.

Answer: 2 hrs and 32 mins

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?

Answers

Answer:

(6, 6).

Step-by-step explanation:

The negative before f(x) reflects f(x) in the x-axis so this makes the new vertex equal to (-6, 3), then the + 3 translates it up 3 units so the required vertex is
