Answer:
3/4
Step-by-step explanation:
Jessica shaded 6/8 of the circle. That fraction can be reduced by removing a factor of 2 from numerator and denominator. The reduced fraction is 3/4.
What is the slope of this graph? 4 14 −14 −4
1 answer:
Answer:
-4
Step-by-step explanation:
The slope of this graph is the gradient. As it is sloping downwards the gradient will be negative, so either -4 or -14.
The gradient can be found by using the equation gradient=rise/run
The line passes through (-2, 5) and (0,-3).
This means the run (x-direction) is -2-0= -2 and the rise (y-direction) is
5 - (-3) = 5+3 = 8
Therefore the gradient is equal to 8/-2 = -4

A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so
A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So
We can rewrite that without the primes and combine the powers of 2.
Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
