Answer:
y=3x+5 is the answer for this question
I assumed that the unit of measure is ft.
Front+back:
S1=2×(4×3.5/2)=4×3.5=14ft²
2 sides+base:
S2=3×(9×4)=9×12=108ft²
Total area: 14+108=122ft²
42
Work backward. 64 at the end. She found 19. Take those away to see how many she had before that. 64-19=45. So she has 45 now. She started with 87. So to find out how many nickels were used for the cookie, subtract 45 from 87. 87-45=42.
Answer:
C
Step-by-step explanation:
Since these lines have the same slope and different y-intercepts, they are parallel lines. As such lines do not intersect, we can say that :
The system has no solutions.
