Answer: 45 MILES
Step-by-step explanation:
3 TIMES 15 = 45
Sub your values into the equation
if y = -1/6 x + b
6 = -1/6 * -6 + b
6 = 1 + b
b = 5
so y = -1/6x + 5
Because the triangle is iscosceles, the two angles on the same leg are the same. So the equation will be
angle 1 = angle 2
5x = 3x +20
Now, solve it
5x = 3x + 20
5x - 3x = 20
2x = 20
x = 20/2
x = 10
The value of x is 10
For this case we have the following system of two equations with two unknowns:
We want to know if the point is the solution of the system:
We replace:
, meets the first equation.
does not comply with the second equation.
Therefore, it is not system solution.
Answer:
The point is not system solution
On the first question, the formula would be m=\frac{y2-y1}{x2-x1} and the value we got is -4/3, so D.
On the second quesiton, the slope in the given equation of the line is -2, its negative reciprocal is 1/2, so A.
On the third question, use the slope formula above and the value you would get is zero, so A.
On the fourth question, the equation of the line perpendicular to line QR is y=2x+b, to find b, just substitute the point (5,6) to the equation. That would make b = -4. the final equation of the line would be: y=2x-4, so D.
On the fifth question, the equation of the line parallel to line QR is y = -2x + b. substitute the point (4,5) to the equation, and you'll get b = 13. the final equation of the line would be y=-2x+13, so A.
