Hi! So if this is on a graph the line would be straight up and down. However if you are given an ex tell you you would insert the x value into the equation by multiplying it by 4 to get the Y value.
![\frac{9(14+16)*2-(8*4+12*9)}{40} \\ \frac{(9*2)(14+16)-[(8*4)+(12*9)]}{40}\\ \frac{(18*30)-(32+108)}{40}\\ \frac{540-140}{40}\\ \frac{400}{40}\\ 10](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%2814%2B16%29%2A2-%288%2A4%2B12%2A9%29%7D%7B40%7D%20%5C%5C%0A%5Cfrac%7B%289%2A2%29%2814%2B16%29-%5B%288%2A4%29%2B%2812%2A9%29%5D%7D%7B40%7D%5C%5C%0A%5Cfrac%7B%2818%2A30%29-%2832%2B108%29%7D%7B40%7D%5C%5C%0A%5Cfrac%7B540-140%7D%7B40%7D%5C%5C%0A%5Cfrac%7B400%7D%7B40%7D%5C%5C%0A10)
So the expression is equal to
10.
Given:
The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).
To find:
The vertices for
.
Solution:
The rule
represents refection of polygon QRST across the x-axis.
If a figure is reflected across the x-axis, then

Using this rule, we get




Therefore, the vertices for
are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).
As the spinner is spun twice the order pairs which have a product less than 14 and contain at least one odd number are ( 2,3), ( 2,5), ( 3,2), ( 3,3), ( 5,2)
= 5 order pairs
Option B is correct
Note: see the attached image to comprehend how we find order pair( for beginner <span />
Between 2² and 3².
2√5 is gonna be a little greater than 2*2, or 4. But definitely less than 3², or 9
