Answer:
$49.55
Step-by-step explanation:
multiply 5.25 by 12 then subtract thetnumber by 13.45
Part a
For horizontal 8*50% = 4 and for vertical 12*75%= 9.
So these values are less than the originals so the new frame is a reduction.
Part b
For horizontal 8*125% = 8*1.25 = 10 and for vertical 12*140% = 12*1.4 =16.8
So these values are greater than the originals sothe new frame is a enlargement.
Using the principle of parallel lines, the value of x in the given triangle is calculated to be 8
<u>The</u><u> </u><u>smaller</u><u> </u><u>triangle</u><u> </u><u>can be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base = 6/x ----(1)
<u>The</u><u> </u><u>larger</u><u> </u><u>triangle</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>:</u>
- Side / base
- Side = 6+9 = 15
- 15/20 - - - - - (2)
<u>Equating</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>and</u><u> </u><u>(</u><u>2</u><u>)</u><u> </u><u>:</u>
6/x = 15 / 20
15x = 20 × 6
15x = 120
x = 120 / 15
x = 8
Therefore, the value of x in the triangle is 8.

Answer:(when the equation is written as y=mx+b) the slope is the number m that is multiplied on the x, and the b is the y intercept that the point where the line crosses the vertical y-axis
Step-by-step explanation:y=mx+b
=(-3)x+(12)
y=-3x+12
