In case you don't know your times-3 numbers well enough to recognize the answer right away, you can check the second data point.
.. a. 2^3 = 8 ≠ 6
.. b. 3^2 = 9 ≠ 6
.. c. 3*2 = 6
.. d. 2 +3 = 5 ≠ 6

Only selection C makes sense.

Answer: option c: y = 3x

Justification:

All the ordered pairs meet that the second number of the pair equal 3 times the first number of the pair:

Here is the proof:

Pair         first number times 3   second number of the pair
  
(1, 3)         3 * 1 = 3                         3   => check

(2,6)          2 * 3 = 6                         6   => check

(3,9)          3 * 3 = 9                         9   => check

(4,12)        3 * 4 = 12                      12 => check

(5, 15)       3 * 5 = 15                      15 => check.

So, all the pairs meet the rule y = 3x

How do you factor 7x^{2}+29x+4
Gala2k [10]
When you have a coefficient in front of the "x^2" value, you have to multiply it by the end value (4)

so you want a set of integers that will add up to 29, by multiple to (7 x 4) = 28

The only numbers like that are 28 and 1, they add up to 29 and multiply to 29

Therefore, rewrite it like this 7x^2 + 28x + x + 4

and then factor out the 7x in the first two terms, to get this 

7x(x+4) + x + 4, then factor out 1 in the latter two terms to get this:

7x(x+4) +1(x+4), then use grouping to combine what you've got:

The factors are: {{  (7x+1)(x+4)  }}

What are the answers I have to put in the yellow boxes?
valentinak56 [21]

The expression 1x² + 14x + 40 is a quadratic expression, and the answers in the yellow boxes are 40 and 14

<h3>How to complete the boxes?</h3>

The quadratic expression is given as:

1x² + 14x + 40

This implies that:

a = 1

b = 14

c = 40

Because a quadratic expression is represented as:

ax² + bx + c

The expressions in the yellow boxes are:

a * c and b

So, we have:

a * c = 1 * 40 = 40

b = 14

Hence, the answers in the yellow boxes are 40 and 14
