Answer:
1. 3x = 12 . the answer is d. x = 4
The answer is multiplication.
15 x 4 = 60
60 divided by 4 = 15
There are 4 times as many ribbons in the large ones as in the small one.
You would have 60 different types of pens with this brand. You need to multiply 12 and 5 (because you have 12 different colors for every type of tip, so you have 5 groups of 12).
To reduce this equation to lowest terms, we must first determine the factors of both the numerator and denominator. For the numerator, n^2-7n-144, the factors are (n-11) and (n+4). For the denominator, n2-121, the factors are (n-11) and (n+11). We can cancel out like terms, which is (n-11), leaving the lowest term (n+4)/(n+11).
Answer:
they both must go through (0, 0) and both must be straight lines
Step-by-step explanation:
