Divide by 21 to put the equation in intercept form.
x/(21/9) + y/(-21/7) = 1
x/(7/3) + y/(-3) = 1
The x-intercept is (7/3, 0)
The y-intercept is (0, -3)
The 3rd choice is appropriate.
D) these two figures are similar they don't look similar at first because the X'Z'Y' is more upwards. But they are congruent meaning they are similar or exactly the same almost. This basically tells me that I need to use translation.
E) I can use reflection to get XYZ into X'Y'Z' by reflecting it across the x-axis. I could also use translation and move it up 6 and then move it to the right.
C) The last one I could use is rotation and move it around around 45* or something close to the the other one.
350 - 213 - 155 + 78 = 60 students not in either
Let Tory’s sister age = x
Since Tory is 3 years older than her sister ,
Tory = (x + 3)
let Quentin’s brother age = x
( because quentin’s brother & tory’s sister are the same age , we can let both their ages be x )
Since Quentin is 8 years less than twice his brother’s age ,
Quentin = (2x -8)
Since Quentin and Tory are the same age ,
x + 3 = 2x - 8
-x = -8-3
x = 11
Ans : 11 years old :)
I’m so sorry if this is incorrect
Sin = opposite / hypotenuse so SinS = QR/68. You have to use Pythagorean Theorem to find QR.
