Answer:
Triangle ABC is similar but not congruent to Triangle XYZ
Step-by-step explanation:
When you dilate the size changes but the angles are the same with makes them similar and since the size of the triangles are different they cannot be congruent.
Answer:
y=3x-7
Step-by-step explanation:
lines are parallel hence gradient from the equation in question is the same as the gradient of the equation to be found.. comparing to y=mx+c, eq in question has grad 3... from the formula y-y1=m(x-x1) where (x1,y1) is equal to the point in question
Answer:
one solution
Step-by-step explanation:
2/3(3y+6)=0
Multiply by 3/2
3/2 *2/3(3y+6)=0*3/2
3y+6 = 0
Subtract 6 from each side
3y = -6
Divide by 3
3y/3 = -6/3
y = -2
There is one solution
Answer:
(C) 18
Step-by-step explanation:
We can create a systems of equations. Assuming 
is Michelle's age, 
is Joan's age, and 
is Ryan's age, the equations are:
We can use substitution, since we know the "values" of m and j.
So we know that Joan is 18 years old.
Hope this helped!
The formula to find the arc length L is
L = r*theta
where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)
If the central angle is 1 radian, then theta = 1 and
L = r*theta
L = r*1
L = r
So the arc length is the same as the radius
Answer: Choice A) The radius of the circle
