Q.13 is no solution since the y intercept of the 2 equation differ but gradient is the same therefore if you were to draw a graph there wont be any intersection between the equations
the next question's answer is no solution
Answer:
13
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -9-4)/(6-7)
= -13/-1
= 13
Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
Answer:
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
so
In this problem
solve for x
Multiply by 2 both sides
subtract 2x both sides
Adds 1 both sides
Yes, because the sample is random. If she had chosen the participants in any way other than randomly, it would not be representative of her entire school.
