Answer:

(3x - 7)(x - 1).

Step-by-step explanation:

3x^2 - 10x + 7

We need 2 numbers whose product is 21 and sum = -10.

These are -3 and - 7 so we write:

3x^2 - 10x + 7

= 3x^2 - 3x - 7x + 7 Now we factor by grouping:

= 3x(x - 1) - 7(x - 1)

= (3x - 7)(x - 1).

The graph of function f is shown. Function g is represented by the table. Which statement correctly compares the two functions?

Dafna1 [17]

Answer:

Option (A)

Step-by-step explanation:

Graph of function 'f' represents,

x - intercept of the function 'f' → (1, 0)

y - intercept of the function → (0, 6)

As x-approaches ∞, value of the function approaches (-2)

Points in the given table is for the another function 'g'

x - intercept of the function 'g' → (1, 0) [For x - intercept, y = 0]

y - intercept of the function 'g' → (0, 3) [For y - intercept, x = 0]

As x approaches ∞, value of function 'g' approaches (-1).

Therefore, x - intercepts of both the functions are same but end behavior are different when x → ∞.

Option (A) will be the answer.

What is the equation of the line whose slope is 1/3 and y-intercept is -4?

faltersainse [42]

Answer:

y=1/3x-4

Step-by-step explanation:

the slope-intercept format of the line is y=mx+b, where m is the slope and b is the y intercept.

we are given the slope (1/3) and the y intercpet (-4).

substitute the numbers into the equation

y=1/3x-4

the answer is y=1/3x-4

hope this helps!

Ellen flipped a coin 80 times. the coin landed heads up 44 times and tails up 36 times. what is the experimental probability of

Vaselesa [24]

Answer:

$\frac{9}{20}$

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>

<u />

Hence

P (tails) = 36/80 = 9/20
