Hi there! I can help you.
Rate: To find the rate, let’s divide interest earned by the principal. When you do, you get 0.15. Multiply by 100 to get 15 and divide by 3 to get 5. The simple interest rate is 5%.
New balance: All you have to do is add the principal and he new balance. When you do, you get 517.5. The new balance is $517.50.
Answer:
U=19
A=8
B=5
Step-by-step explanation:
Cardinality refers to the number of elements in a set.
Answer:
A, B, C and D.
Step-by-step explanation:
Opposite sides are congruent (B) as well as the 3 that are marked.
+ y = -1 ⇒ y =
- 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope
by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 +
⇒ y =
+ 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.
Answer: No Solution
