Answer: if the y intercept is 3 it would be the one that has a point at 3 on the y intercept and from that point a rise of 2 and a run of 3
Step-by-step explanation:
Use this for lojg divisions
39 goes outside of the symbol
1004 goes in
you then realize everything you do is basically the opposite of multiplying
use 34 as your guide and break 1004 into pieces
start with 34÷10
you can't do it so you add the next nunber to the problem
34÷100
well you could divide it completely, but adding and counting the times you did it is a lot easier, or subtracting.
for this sake we will| use subtraction
100-34=66
66-34=32
in your calculator you get 2 and a long decimal, but for this sake you just drop it
to finish this problem off you drop your remainding numbers and figure our what multiplies into what.
U correct 2.25 is the evelvation before its decent
Step-by-step explanation:
similar triangles means that all angles in one triangle are exactly the same as the angles in the other triangle.
and the lengths of all sides of one triangle have the same scaling factor with the lengths of the sides of the other triangle.
so, when we compare the "features" of the triangles, we see that C corresponds to S, B to R and D to T.
so, DC (50) corresponds to TS (70).
and that means that CB (60) corresponds to SR (11x - 4).
the scaling factor from BCD to RST is 70/50 = 7/5.
that means DC × 7/5 = TS.
and CB × 7/5 = SR :
60 × 7/5 = 11x - 4
12 × 7 = 11x - 4
84 = 11x - 4
88 = 11x
x = 8
Answer:
Step-by-step explanation:
Solving (a): 241^257 mod 12
To do this, we simply calculate
Because
The highest number less than or equal to 241 that is divisible by 12 is 240; So:
Hence:
Solving (b): 7 * 20
Solving (c): Multiplicative inverse of 7 in 719
The position of 7 in 719 is 700
So, the required inverse is 1/700 ---- i.e. we simply divide 1 by the number
