Well, if you look into it, inspect element thsi, really. I believe it is either A, Or C. But I am more strong with A.
Answer:
You have to graph and label the points
Step-by-step explanation:
3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle
-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4
2 is just a horizontal line starting at (closed circle) 4, it is greater than also.
If you don't understand the the constants (the numbers on their own) just a vertical translation.
If the cross either the x or y axis, you have to find that too, im pretty sure.
To find the y axis intercept, make x = 0 and solve for y
and to find the x axis intercept, make y = 0 and solve for x
Answer:
We know that the equation for the speed is:
Speed = Distance/time.
First, we know that he walks 2 miles in 15 minutes.
distance = 2miles
time = 15 minutes
Then his speed in that interval is:
Speed = (2 mi)/(15 min) = (2/15) miles per minute.
Now, at this same speed, he wants to walk 3 more miles. And we want to find the equation that represents how much time she needs to walk 5 miles (the 2 first miles plus the other 3 miles)
We use again the equation:
Speed = Distance/Time
But we isolate Time, to get:
Time = Distance/Speed
Where:
Distance = 5 miles
Speed = (2/15) miles per min
Time = (5 miles)/((2/15) miles per min) = 37.5 minutes
She needs 37.5 minutes to walk the 5 miles.
Answer:
22.5%
Step-by-step explanation:
9/40 x 100= 22.5
Answer:
B
Step-by-step explanation:
you add 3 plus 2 which gives you 5
then it said one red marble which is 2/5 then it said another one which is 1/4
2/5 times 1/4 equals 1/10
