Answer:
1
Step-by-step explanation:
We need to find the factors of 18 and 35
Breaking into prime factors
18 = 2*9 = 2*3*3
35 = 5*7
There are no common factors so the greatest common factor is 1
Explanation:
A. When you examine the values in the table, you see the y-value is not proportional to the x-value. That is, 20/1 ≠ 26/2. However, you do notice that the y-values increase by 6 when the x-values increase by 1. <em>The ratio of these increases is the slope of the graph of the relation between y and x</em>.
Since the slope is 6, we might expect a value of 6×1 = 6 for x=1. However, the y-value for x=1 is 20, which is 14 more than what might be predicted by the slope. <em>This added extra is the y-intercept on the graph of the relation</em>.
The slope is 6 and the y-intercept is 14.
__
B. The slope is (26-20)/(2-1) = 6.
__
C. For x=1, the slope-intercept equation tells us ...
y = 6x +b
20 = 6·1 + b . . . . . . . . . . substitute (x, y) = (1, 20)
20 -6 = 14 = b . . . . . . . . subtract 6 to find b
Answer: D) CPCTC
<u>Step-by-step explanation:</u>
step 6 proves the triangles are congruent.
step 7 states that if the triangles are congruent, then parts of the triangle are congruent.
Congruent Parts of Congruent Triangles are Congruent (CPCTC)
Round each number to the nearest 10.
33 rounds to 30 and 89 rounds to 90, thus in your head it's easier to mentally add 30 + 90 for purposes of estimation.
