Answer:
x=12
Step-by-step explanation:
32/2x = x/9; because the triangles are similar
32 = 2x^2/9
288 = 2x^2
144 = x^2
x = 12 or x = -12, but the latter is nonsensical.
The correct answers are:
6. 3x-y=-1
In slope intercept form this equation has a slope of 3 and point 1,4 is included on the graphed line: y=3x+1 is slope intercept form.
7. 2x+y=11
In slope intercept form this equation has a slope of -2 and point 4,3 is included on the graphed line: y=-2x+11 is slope intercept form
10. 4x-7y=-17
In slope intercept form this equation has a slope of 4/7 and point 1,3 is included on the graphed line: y=4/7x+17/7 is slope intercept form
11. 3x+2y=12
In slope intercept form this equation has a slope of -3/2 and point 2,3 is included on the graphed line: y=-3/2x+6 is slope intercept form
You basically just find the slope intercept form of each question then convert the intercept form over to standard form then graph in intercept form to see if the point lies on the line :)
I’m not 100% sure, but I believe it’s A and C
-6-/3-7/*4/8-(-2)
-6-4*4/8-(-2)
-6- 16 /8-(-2)
-6 -2 - (-2)
-8 - (-2)
-6
Hope this helped
