Answer:
-9
Step-by-step explanation:
Here we use the slope formula: m= y2-y1/x2-x1. We simply plug in the numbers we know: -1/10 = -5+6/t-1. Then we solve for t. Multiply both sides by (t-1) so -1/10 (t-1)= 1. Then multiply both sides by -1/10 so t-1= -10 and then add one to both sides so t=-9.
Answer:
# of laps < 28, the number of laps will be less than 28.
1 lap = 4 minutes
28 laps = 112 minutes
Because we want less than 28 laps,
27 laps = 108 minutes
She can run any amount of laps less than 28.
Answer:the answer is 14.6

Hey there! I'm happy to help!
When evaluating the value of an expression, we need to follow the order of operations which is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction).
First, we will evaluate the exponent. 3² is 3×3 which is 9.
Now we have to do multiplication. Since the multiplication sign is between the 2 and the 8, that is what we multiply.
Then we will do our addition and subtraction.
Since all fractions are just division problems, we can do 25÷5.
25÷5=5
So, the value of this expression is 5.
Have a wonderful day and keep on learning! :D
Answer:
-4
Step-by-step explanation:
Indeed, the y-value changes by 4 when the x-value changes by 1. However, the y-values <em>decrease</em> when the x-values increase. That means the slope is <em>negative</em> 4.
___
Any line that goes down to the right has a negative slope. Its slope is positive if it goes up to the right.
