William left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 2 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 5 minutes. Then he drove home at a speed of 12 blocks every minute. Make a graph showing the number of blocks away from home that William is x minutes after he leaves his house, until he get back home.
Answer:
17 minutes
Step-by-step explanation:
First distance in blocks and time.
x1= 8 b and t1 = 4 min
Second distance in blocks and time.
x2= 8 b and t2 = 6 min
Third distance in blocks and time.
x3= 24 b and t3 = 12 min
Fourth distance in blocks and time.
x4= 24 b and t4 = 17 min
Final distance in blocks and time.
x5= -24 b and t5 = 19 min
The first trap Willian is 8 blocks from home, we know that the speed is 2 b/min (blocks per minute). Using the definition of speed V1 = x1/t1 we can find t1. t1 will be t1 = 8/2 = 4 min.
He spends 2 minutes, so t2 = 6 min.
Now, the new speed is V2=4 b/min and go to the bank that is 16 blocks away from store, so x2 = 16 + 8 = 24 b. Times will be t = 24/4 = 6 min. But we need to add to t2 to get the total time. t3 = 6 + 6 = 12 min.
He spends 5 minutes here, so t4 = 12 + 5 = 17 min.
Finally, he drove home at -12 b/min, so the time to get home will be:
t = 24/12 = 2 min. Therefore, the total time t5 = 17 + 2 = 19 min.

what is the answer to 4(x + 1) = 4x + 10
Answer:
No solution
Step-by-step explanation:
First we would have to see if anything has to be distributed and yes the 4 in the expression 4(x + 1) has to be distributed to the x and 1. So we would multiply the 4 by x and 1. Now we have 4x + 4 = 4x + 10. We have to get the x's on 1 side of the equation so we would do the inverse of one of the x's and we can only subtract. So we can subtract 4x on both sides. So now we have
4 = 10. That isn't a correct statement so there is no solution.
4 does not equal 10.
A scooter travels 30 feet in 2 seconds at a constant speed.
What is the speed of the scooter in feet per second?
Answer:
15
Step-by-step explanation:
Since it goes 30 in 2 seconds, we need to divide 30 and 2 and end up with 15.
To make sure our answer is correct we know that 15 is one second, so we can add 15+15= which will give us 30, and will also land at 2
Brainliest pls
The speed of the scooter is 15 feet per second.
To calculate the speed of the scooter in feet per second, you can use the formula:
Speed = Distance / Time
The distance traveled by the scooter is 30 feet, and the time taken is 2 seconds.
Plugging these values into the formula, we get:
Speed = 30 feet / 2 seconds
Speed = 15 feet/second
Therefore, the speed of the scooter is 15 feet per second.

Step-by-step explanation:
(f.g)(_1)=f(6)
=8/6+2
=8/8
=1
The value of (f o g)(-1) is 1 if the function f(x) = 8/(x + 2) and g(x) = 4x² + 2 the answer is 1.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Two functions:
f(x) = 8/(x + 2)
g(x) = 4x² + 2
g(-1) = 4(-1)² + 2
g(-1) = 4 + 2
g(-1) = 6
f(g(-1)) = 8/(x + 2)
f(g(-1)) = 8/(6 + 2)
f(g(-1)) = 8/8
f(g(-1)) = 1
Thus, the value of (f o g)(-1) is 1 if the function f(x) = 8/(x + 2) and g(x) = 4x² + 2 the answer is 1.

a typical car releases 36 tons of carbon dioxide and six years at a constant rate how many times will a car release in 10 years ?
Answer:
60 Tons
Step-by-step explanation:
36 divided by 6 equals 6. So that six is used for the for extra years
36+6+6+6+6
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A typical car releases 36 tonnes of carbon dioxide and six years.
Let 'x' be the amount of carbon dioxide.
At a constant rate, the number of tonnes of carbon dioxide released in 10 years will be given as,
x / 10 = 36 / 6
Simplify the equation, then we have
x / 10 = 36 / 6
x / 10 = 6
x = 60 tons
The number of tonnes of carbon dioxide released in 10 years will be 60 tonnes.

If we look at just the area of intersection, it looks like an X. Think of the X as two lines intersecting. Each side equals 180°, and because both triangles are made up of those sides, we can conclude that the angles are congruent as well.
