Answer:
b = 18
Step-by-step explanation:
1st step is isolating b by moving 2 to the other side. When you move a number the the other side it flips (from + to - or × to ÷). The 2 in this question is being multiplied my b (no sign means multiply) so when you move it to the other side it becomes 36/2 or 18
Steps:
2b=36
b=36/2
b=18
Answer:
-3
Step-by-step explanation:
Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)
----------------------------------------------------
Explanation:
To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head
In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)
Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D
Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S
4(4x)+2(x)=72
16x+2x=72
18x=72
x=4
