Answer:
y = -1/3x + 5
Step-by-step explanation:
-1/3 is the slope
5 is the y-intercept
Hey there!
The answer is C.
First of all, let's assign variables. We can use t for tricycles and b for bicycles.
Next let's look at the first statement:
"There are at most 12 bicycles and tricycles in a school playground."
"At most" means the number 12 will be included in the inequality, so the sum of b and t is at most 12.
We can write this as b + t ≤ 12.
Now we can look at the second statement:
"There are at least 17 wheels altogether."
"At least" means the number 17 will be included in the inequality.
Since each bicycle has 2 wheels and each tricycle has 3 wheels, the sum of 2b and 3t is at least 17.
That can be written as 2b + 3t ≥ 17.
Our final system of inequalities:
b + t ≤ 12
2b + 3t ≥ 17
This matches option C.
Hope this helps!
Answer:
x/7 ≤ -25
x ≤ -175
Step-by-step explanation:
Quotient means division
x/7 ≤ -25
Multiply each side by 7
7*x/7 ≤ -25*7
x ≤ -175
