1/4
Step-by-step explanation:
If there are 4 gold coins, and 1 silver coin, there is 1 silver coin to 4 gold coins. This results in 1 to 4 , 1/4.
I think the first question is A)
Answer:
Area= 32 (formula is: length x width)
Perimeter= 8 + 4 + 8 + 4= 24
Step-by-step explanation:
Answer:
1. no solution
2. one solution
3. infinitely many solutions
4. one solution
Step-by-step explanation:
1. same slope, different intercepts, parallel lines, no solution
2. different slopes, lines intersect at 1 point, one solution
3. same equation, infinitely many solutions
4. different slopes, lines intersect at 1 point, one solution
Answer:
<u>y = 3x + 8</u>
Step-by-step explanation:
line a: y = 3x + 11
This means that the slope is 3 and the y intercept is 11.
(-1,5)
line b: y = 3x + b <--- we need to solve for b and plug in the numbers from the coordinates
Just plug in the numbers!
5 = 3(-1) + b
5 = -3 + b
5 + 3 = b
8 = b
The y intercept is b! So the equation is:
y = 3x + 8
