Answer:
vertex is (2,-5)
Step-by-step explanation:
y = a(x – h)^2 + k
the vertex is (h,k) in the equation h =2 and k = -5
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.
Answer:
No
Step-by-step explanation:
I'm not quite sure what a ratio table is, but I can explain it the way I understand it.
The initial ratio is 10:8 which is 1.25 as a decimal.
Now let's add five to each number to represent the kids joining the class, this will result in the following:
15:13 which is 1.153846154 as a decimal.
Therefore, the ratio doesn't stay the same just because you added the same number of people to each group.
Hope this helps :)
Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
