Help me pleaseeeeeeeeeee
2 answers:
7x + 6y = -42
For this case what you should do is see the intersections with each of the axes and then join the ordered pairs.
We have then:
For the x axis:
y = 0
Substituting in the equation:
7x + 6 (0) = - 42
7x + 0 = -42
x = -6
For the y axis:
x = 0
Substituting in the equation:
7 (0) + 6y = -42
0 + 6y = -42
y = -42 / 6
y = -7
We graph the ordered pairs:
(x1, y1) = (- 6, 0)
(x2, y2) = (0, -7)

Answer:
A. GCF(a,b) =
B. LCM(a,b) =
Step-by-step explanation:
The GCF of two or more integers is their greatest common factor. In order to find it, you must factorise them first and then do the product of the factors that appear in all the factorisations, with their least exponent.
Hence, the GCF of and
is
.
The LCM of two or more integers is their least common multiple. In order to find it, you must factorise them first and then do the product of the multiples that appear in one or all the factorisations, with their greatest exponent.
Hence, the LCM of and
is
