Answer:
The equation of the line is y = (5/2)x + 5.
Step-by-step explanation:
When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :
y = (5/2)x + b
let x = -2, y = 0,
0 = (5/2)(-2) + b
0 = -5 + b
b = 5
D=rt and we are told d=546 and r=1.3m/s so
1.3t=546 divide both sides by 1.3
t=420 seconds so
420s(min/60s)=7 min
So it takes him 7 minutes to walk to Sara's house.
I'm just guessing because there isn't much data, but the ages could be:
1, 8, and 9
3, 3, and 8
1, 8, and 9
1, 6, and 12
2, 3, and 12
3, 4, and 6
2, 4, and 9
(These aren't all the possible ages)
Answer:
A. 5
Step-by-step explanation:
The triangle will be a right triangle when the side lengths satisfy the Pythagorean theorem: the sum of the squares of the legs is equal to the square of the hypotenuse.
(x +1)^2 +x^2 = (√61)^2
x^2 +2x +1 +x^2 = 61 . . . eliminate parentheses
2x^2 +2x = 60 . . . . . . .subtract 1, collect terms
x^2 +x -30 = 0 . . . . . divide by 2, subtract 30
(x +6)(x -5) = 0 . . . . factor the quadratic
x = -6 or +5
The solution is x = 5.
_____
Side lengths cannot be negative. Solution values are values of x that make the factors zero. x+6=0 when x=-6, for example.
