3x^2+ 2x -18x -12
= (3x^2+ 2x) -(18x+ 12)
= x(3x+ 2) -6(3x+ 2)
= (3x+2)(x-6)

Final answer: (3x+2)(x-6)

Y=log(x-3)<br><br>what would be the base?
timurjin [86]
By definition, if :

a^y = b

y = log_a b

<span>We highlight the following elements:

</span><span>a = Base of the logarithm;
b = logarithmand or antilogarithm
y = logarithm</span><span>

Therefore:

</span><span>Note that since the base was not specified, we know that it is equal to 10.
</span>
y = log_a b
y = log_{10} (x-3)
10^y = (x-3)
<span>
Answer:

</span>Base of the logarithm = 10

What is the slope and y-intercept of the line 3x - 4y = 12?*
Lorico [155]

Answer:

m = 3/4; b = -3    

Step-by-step explanation:

1) First, put the given equation into slope-intercept form. This is so we can identify its slope and y-intercept easily. Isolate y:

3x-4y = 12\\-4y = -3x+12\\y = \frac{3}{4} x-3

2) Lines that are in slope-intercept form are represented by the formula y = mx + b. The number in place of m, or the coefficient of the x-term, represents the slope. The number in place of b represents the y-intercept. So, the slope of  y = \frac{3}{4} x-3  is \frac{3}{4}, and its y-intercept is -3.

A gym has 2kg and 5kg weights. There are 10 disks in all. The total weight of 2kg and 5kg disks is equal to 29kg. Find the numbe
Simora [160]

Answer:

no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7

Step-by-step explanation:

Let the no of 2kg disks be a.

Let no of 5 kg disks be b.

2a+5b=29

a+b=10

Using substitution, we have

2(10-b) + 5b=29

20-2b+5b=29

20+3b=29

3b=9

b=3

So no of 5 kg disks is 3, and no of 2 kg disks is (10-3) i.e. 7
