Okay, first of all, you are probably stuck and don't understand what an exterior angle is. I don't know how to explain it but the exterior angle in this case is ∠DAB.
<h2>∠DAB = ∠ABC + ∠BCA</h2><h2> = 90° + 62°</h2><h2>= 152°</h2><h2 /><h2>They said that the exterior angle was instead 128 degrees. This means that now the sum of the angles of B and C are 152 degrees, or, 152 - 128 = 34 degrees greater.</h2>
Answer:
f(x+2) = - 6x - 5
Step-by-step explanation:
As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.
- 3 = 2/5(0) + c
c = - 3
y = 2/5x - 3
17X-7Y. You add or subtract the same variables, in this case you only have two x's and one y. So you add them, because you have a addition sign. 13x+4x and you leave the Y alone, because there is not another Y variable.
