Equation of a line: y=mx+b
m=slope(-1)
b=y-intercept(-7)
y=-1x-7 or y=-x-7
In 6 months, Simple interest of $6 will be earned for investing $100.
<u>Step-by-step explanation:</u>
Step 1:
Given details are Principal (P) = $100, SI rate (R) = 12%, Time (T) = 6 months = 0.5 years
Step 2:
Calculate Simple Interest by the formula SI = PRT/100
⇒ SI = 100 × 12 × 0.5/100
⇒ SI = $6
i think the last one Y = 1X

See the step-by-step explanation
Step-by-step explanation:
Let c be any element of C. (I'm not sure wether you have to assume that C is non-empt or not)
C is a subset of B. That means that as c is in C, it is also in B. (
)
Now, B is a subset of A. It follows that as
.
That means c is an element of A. The predicate Q is true for all elements of A, including c.
Because we let c be any element of C, we have proven that the predicate Q is true for all elements in C.
