Answer: Last option
(42÷2) +5
Step-by-step explanation:
We know that Mr. Roberts drove 42 miles on Monday.
On Tuesday Mr. Roberts drove half of what he drove on Monday plus 5 miles.
If we want to know how many miles Mr. Roberts drove on Tuesday then we should divide 42÷2 to find half of 42.
Then we know that in addition to the 21 miles he drove 5 more miles. Then we add 21 +5 = 26 miles.
So the expression that gives us the number of miles that Mr. Roberts drove on Tuesday is:
(42÷2) +5
Answer:
1/10 of an hour.
Step-by-step explanation:
Lola rode her bike for 7/10 of an hour on Saturday.
She rode for 3/5 of an hour on Sunday.
On Saturday she rode -
= 1/10 of an hour more.
We have to set up 2 different equations if we are to solve for 2 unknowns. The first equation is x = y + 4. One number (x) is (=) 4 more than another (y + 4). Since we have determined that x is larger (cuz it's 4 more than y), when we set up their difference, we are going to subtract y from x cuz x is bigger. The second equation then is 
. In our first equation we said that x = y + 4, so let's sub that value in for x in the second equation: 
. Expand that binomial to get 
. Of course the y squared terms cancel each other out leaving us with 8y + 16 = 64. Solving for y we get that y = 6. Subbing 6 in for y in our first equation, x = 6 + 4 tells us that x = 10. Yay!
Answer:
1. Translation 3 units to the right;
2. Reflection across the x-axis;
3. Translation 4 units up.
Step-by-step explanation:
First, rewrite the function in following way:
Apply such transformations:
1. Translate the graph of the parent function 3 units to the right to get the graph of the function
2. Reflect the graph of the function across the x-axis to get the graph of the function
3. Translate the graph of the function 4 units up to get the graph of the function
