Answer:
57
Step-by-step explanation:
in this picture, the are half of the 114. If you add the two y angles it will equal the angle outside of the triangle
Answer: The graph is below
======================================================
Explanation:
If x = 0, then,
g(x) = -x+1
g(0) = -0+1
g(0) = 0+1
g(0) = 1
Therefore, x = 0 leads to y = 1. The point (0,1) is on the g(x) line.
Now try x = 1
g(x) = -x+1
g(1) = -1+1
g(1) = 0
The point (1,0) is also on the g(x) line.
Draw a line through the points (0,1) and (1,0)
Then erase the portion that is to the left of x = -4
This is because g(x) is only graphed when x > -4; i.e. we're only graphing stuff to the right of x = -4.
We'll have an open hole when x = -4 since we aren't including it as part of the graph.
See below.
X + 9y = 5 .....multiply by -1
4x + 9y = -7
-----------------
-x - 9y = -5 (result of multiplying by -1)
4x + 9y = -7
----------------add
3x = -12
x = -12/3
x = -4
x = 5 - 9y
-4 = 5 - 9y
-4 - 5 = - 9y
-9 = - 9y
-9/-9 = y
1 = y
solution is (-4,1)
====================
3x = 5y - 9
-3x = -2y + 3 ....I rearranged this equation from 2y = 3x + 3
----------------add
0 = 3y - 6
6 = 3y
6/3 = y
2 = y
3x = 5y - 9
3x = 5(2) - 9
3x = 10 - 9
3x = 1
x = 1/3
solution is (1/3,2)
====================
10x - 3y = 5....rearranged from 10x - 5 = 3y
2x - 3y = 1...multiply by -1
---------------
10x - 3y = 5
-2x + 3y = -1 (result of multiplying by -1)
---------------add
8x = 4
x = 4/8
x = 1/2
10x - 5 = 3y
10(1/2) - 5 = 3y
5 - 5 = 3y
0 = 3y
0 = y
solution is (1/2,0)
======================
-6x - 4y = 10....multiply by -2
-12x - y = 13
----------------
12x + 8y = -20 (result of multiplying by -2)
-12x - y = 13
-----------------add
7y = - 7
y = -7/7
y = -1
-6x - 4y = 10
-6x - 4(-1) = 10
-6x + 4 = 10
-6x = 10 - 4
-6x = 6
x = -6/6
x = -1
solution is (-1,-1)
Answer:
its gon be a mixed number tho: 1 1/3
Step-by-step explanation:
Answer:
You have a maximum when the parabola opens down (-x^2), and a minimum when it opens up (+x^2). In your case, it opens down because of the -. That is the special notation, the vertex of the parabola is already there.
