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.

Answer:
A) SAS
Step-by-step explanation:
The picture gives us that two sides are congruent. We can see that an angle is congruent as well because they share a common point at their tip.
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.
Hope this helps!
Solve for y.
ln(2y−1)=3
Answer y=(e^3+1/2)
for future reference
Answer:
The correct answer should be:
[tex]y=\frac{1}{2}(e^3+1)\text{ or } y=\frac{e^3}{2}+\frac{1}{2}[/tex]
Step-by-step explanation:
We have the equation:
[tex]\ln(2y-1)=3[/tex]
Let’s remove the natural logarithm by raising both sides to e. This yields:
[tex]e^{\ln(2y-1)}=e^3[/tex]
The left will simplify to:
[tex]2y-1=e^3[/tex]
Add 1 to both sides:
[tex]2y=e^3+1[/tex]
Divide both sides by 2. So, the value of y should be:
[tex]y=\frac{1}{2}(e^3+1)[/tex]
Answer:
The correct answer is indeed y = [tex]\frac{e^3+1}{2}[/tex]

Find the values of the variables :)
Answer:
x = 6 , y = 4 , 2 units
Step-by-step explanation:
2y - 6 = y - 2 ⇒ y = 4
3x - 16 = y - 2
3x - 16 = 4 - 2
3x = 18 ⇒ x = 6
Length of sides of square is 2 units
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.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Consider functions f and g. Evaluate the function composition.
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.
