Answer:
B
Step-by-step explanation:
(1 1/2,-2)
solve for x and get 1 1/2
solve for y and get -2
Answer:
Fast car = 45.6
Slower car = 30.4
Step-by-step explanation:
Let the speed of the first car = x
Let the speed of the second car = y
Travelling towards each other.
x *1 + y*1 = 76 miles
x*5 - y*5 = 76 miles. This is kind of tricky. You have to understand that the first car that is 76 miles from the second car and makes up that 76 in 5 hours. The distance they both travel is subtracted out.
Divide by 5
x - y = 76/5
x - y = 15.2 The speeds differ by 15.2
x + y = 76
x - y = 15.2
2x = 91.2
x = 45.6
y = 76 - 45.6 = 30.4
When the two vehicles speeds are multiplied by 5, the difference is 76 km
Let Liam's age= x
Max's age= 25
After two years Max's age= 25+2
After two years Liam's age= x+2
After two years Liam will be half of MAx's age,
So-
Liam's age after 2 years= 11.5 + 2= 13.5
Max's age after 2 years - 27
13.5 is half of 27 answer
Hope I helped~!
The equation takes the x coordinate of the vertex and puts it into an equation in vertex form with the y coordinate and the radius. The radius is entered as its squared value. The general form of a circle is (x-h)^2 + (y-k)^2 = r^2. So yours would look like this: (x-3)^2 + (y+2)^2 = 25
