Answer:
Step-by-step explanation:
in total there is 6x
180/6=30
x=30
2x=60
3x=90
Answer:30°
Step-by-step explanation:
Thera are 3 angles in a triangel. The sum of all angles is 180°
x+2x+3x=180
6x=180
x=180/6=30
It the graph that represents the function given in the table is the graph [3].
The point slope form of a line is given by -
y - y₁ = m(x - x₁)
Given is a line that passes through the points (-2, 5), (0, 3), (1, 2) and (4, -1).
The general equation of the straight line is -
y = mx + c
where -
m is the slope of line
c is the y - intercept
Now -
We can calculate the slope as follows -
m = (2 - 3)/(1 - 0) = -1/1 = -1
Now, at [x] = 0, [y] = 3
Which is the y - intercept.
The equation of the line will be -
y = - x + 3
We will plot the graph and match it with the given ones.
It can be seen that graph 3 is the correct choice.
Therefore, it the graph that represents the function given in the table is the graph [3]. It is plotted and attached with the answer for reference.

The graph that represents the table is the one in the image at the end.
Which graph represents the line in the table?
Here we want to identify the line that represents the given table.
The first thing we can notice is the pair (0, 3). This means that the y-intercept of this line is y = 3.
Also, the next pair is (1, 2)
So, for each increase in x of one unit, we have a decrease of one unit in y, which means that the line goes downwards.
So the correct graph is the one posted below.
Answer:
x = 7 and x = -3
Step-by-step explanation:
x^2-4x-21=0
you can factor to get
(x-7)(x+3)=0
then set each equal to 0
x - 7 = 0 and x + 3 = 0
then just solve for x!
x = 7 and x = -3
Answer:
v = 3
Step-by-step explanation:
All 3 angles = 180\
43 + 89 + 16v = 180
132 + 16v = 180
16v = 180-132
16v = 48
v = 48/16
v = 3
