Use the given slope and point and put it into the point-slope formula
y - y1 = m ( x - x1 )
1 is your x value (x1) and 9 is your y value (y1). M = -3
In point slope form, the answer is
y - 9 = -3 ( x - 1 )
The options are:
A) exactly one triangle;
B) no triangles;
<span>C) more than one triangle.</span>
First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180
We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.
With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.
Hence, the correct answer is C) more than one triangle.
So when we plug it into the equation, we get
| -2 |+| -2(3) |
=2+| -6 |
=8
Answer:
(- 1, 9 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 6 → (1)
y = 9 → (2)
Substitute y = 9 into (1) and solve for x
9 = - 3x + 6 ( subtract 6 from both sides )
3 = - 3x ( divide both sides by - 3 )
- 1 = x
Solution is (- 1, 9 )
