Answer:
30
Step-by-step explanation:
PT = TQ
PT = 7x + 2
TQ = 9x - 6
7x + 2 = 9x - 6
9x - 6 = 7x + 2
9x - 7x = 2 + 6
2x = 8
x = 8 / 2
x = 4
Substitute x = 4 in PT,
PT = 7x + 2
= 7 ( 4 ) + 2
= 28 + 2
PT = 30
Use p.e.m.d.a.s.

then subtract 58Q and 48Q = 10Q

Step-by-step explanation:
height = constant / width
that means
constant = height × width.
so, we only need to multiply the 2 coordinate numbers of one of the points.
the easiest is clearly (0.8, 1).
0.8 × 1 = 0.8
so, the constant is 0.8
The slope of the line is calculated using
y2 - y1 / x2 - x1
Substituting the given values
-8 - 27 / 5 - 0 = -7
The rate of change or the slope is -7
And the initial value is the value of y when x is 0. From the first coordinates, the initial value is 27.
