Answer:
(x-3) (x+4) = 0
Step-by-step explanation:
x^2+x-12=0
What 2 numbers multiply to -12 and add to 1
-3 *4 = -12
-3+4 = 1
(x-3) (x+4) = 0
Answer:
x = 40
Step-by-step explanation:
collect the terms (3-2)x = 40
subtract the numbers 1x = 40
divide from both side 1x/1 = 40/1
solution x = 40
<span>When you have an equation of the form y = mx + b (which you do in this case), the slope is always equal to the coefficient of x, which is m or 12 in this case. Since there is no "b" in your equation, you could say that b=0, and the line is known to cross the y axis at zero.
In case you are interested, if the equation said y = 12 x + 3 the slope of the line would still be 12 but the line would cross the y axis at 3. If the equation said y = 12x -4, the line would have a slope of 12 and would cross the y axis at -4.</span>
Answer:
= 2n²
Step-by-step explanation:
From the sequence 2,8,18,32,50
The difference between each numbers are
: 6, 10, 14, 18
The difference between the second sequence is 4.
Therefore the nth term of the sequence is 2n²
