Answer:
x < 4
Step-by-step explanation:
We have that: 1 + 2x < 9. Let's solve this as if the < sign was an = sign:
1 + 2x < 9
Isolate the variable:
2x < 9 - 1
2x < 8
Divide by 2:
x < 8/2
x < 4
The answer is x < 4.
So, initially 240

-212

were empty:
this is :

12/4 is 4 so that's why i substituted it with 4.
now, later 27 1/3 were used so we add this tho the original empty space

=

=
which is the result!
Answer:
f(x)=x^2
Step-by-step explanation:
Because it is a quadratic function this is the quadratic parent function.
Answer:
5.5
Step-by-step explanation:
The y-intercept of the line graph shown above is the value of the point where the line cuts the y-axis. The y-intercept of this graph is between 5 and 6. However, we can get an accurate value by calculation. This can be done by generating an equation of the line.
Recall the slope-intercept equation,
, where m = slope of the line, b = y-intercept.
To generate the equation of the line, first find slope using the points (-2, 7) and (6, 1):
.
Substitute m = ¾ and the coordinates (6, 1) into the slope-intercept equation to find the y-intercept (b):






Therefore, b = y-intercept = 5.5.
To generate the equation of the line, plug in the values of m and b, we would have:
y = ¾x + 5.5
The y-intercept of the line of the graph is 5.5.
