Answer:
1.
x = (2,0)
y = (0,-8)
2.
x = (-2,0)
y = ( 0, 2)
3.
x = ( 4,0)
y = ( 0, -16)
Step-by-step explanation:
aIll do one equation as an example
f(x) = 4x -8
y = 4x - 8
since its an intercept you know the x, for the y intercept will be zero and vice versa. Its like this cause its on the axis.
So you only need to figure out the y for the y intercept and the x for the x intercept.
- 4x + y = -8
after changing the equation to standar form you then ignore the x base so, 4x to get the y intercept.
- 4x + y = -8 becomes y = - 8 then you add the 0 for the coordinate
y = -8 becomes (0,-8)
f(x) = 4x -8
y = 4x - 8
- 4x + y = -8
y = - 8
(0,-8)
f(x) = 4x -8
y = 4x - 8
- 4x + y = -8
-4x = -8
x = 2
(2, 0)
sorry im not really good at explaining lol
can g et a brainliest for effort at least 5 points isnt much
Step-by-step explanation:
8x² + 8x - 21 = 0
8(x² + x) - 21 = 0
8(x + 0.5)² - 23 = 0
8(x + 0.5)² = 23
(x + 0.5)² = 23/8.
<h2>
It is an obtuse angle.</h2>
Step-by-step explanation:
Obtuse: An obtuse angle is an angle more than 
but less than 
.
Example : 
,
etc.
Acute : An acute angle is an angle less than
Example : 
,
etc.
Straight : A straight angle is .
Right: A right angle is .
Since the angle is more than but less than . So, it is an obtuse angle.
