Answer:
x=-3
Step-by-step explanation:
F(x) just means X.
0=x+3
0-3=x+3-3
-3=x
Answer:

Step-by-step explanation:
We are given two points, the y - intercept and the x - intercept.
The y - intercept being: ( 0, -7 )
The x - intercept being: ( 1, 0 )
The equation of a line in slope - intercept form is:
y = mx + b, where m is the slope and b is the y - intercept.
We already have the y - intercept. So far we have:
y = mx - 7
What we're missing is the slope.
To find the slope, we can use this formula:
, where
and
are the x - coordinates of both points and
and
are the y - coordinates of both points.

We now have the missing piece, the slope, so the equation now is:

-10-20d that’s the answer
70°
(the sum of the angles of a triangle is 180°
180 - 40 = 140.
140/2 = 70
The other 2 angles are 70°
70° + 70° + 40° = 180°).
