Answer:
The answers are that a = -5 and b = 1
Step-by-step explanation:
In order to find A and B, we first need to find the equation of the line. We can do this by using two ordered pairs and the slope formula. For the purpose of this activity, I'l use (0, 5) and (-3, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 5)/(-3 - 0)
m = 6/-3
m = -2
Now that we have this we can model this using point-slope form.
y - y1 = m(x - x1)
y - 5 = -2(x - 0)
y - 5 = -2x
y = -2x + 5
Now that we have the modeled equation we can use the ordered pair (a, 15) to solve for a.
y = -2x + 5
15 = -2(a) + 5
10 = -2a
-5 = a
And we can also solve for b using the ordered pair (2, b)
y = -2x + 5
b = -2(2) + 5
b = -4 + 5
b = 1
Answer:
1) isosceles triangle
2) 4500cm^2 or 0.45 m^2
3) 55 degrees
4) Angle SUT
5) Triangle Inequality Theorem - the sum of two side lengths of a triangle is always greater than the third side. If 8 cm is your third side, then the triangle could be constructed because 9 + 5.5 > 8.
6) SAS - Side Angle Side

Answer:
I think it's $280
Step-by-step explanation:
Hello :
<span>6(m-1)=3(3m+5)
6m-6=9m+15
6m - 9m = 15+6
-3m =21
m = 21/-3 = -7</span>
