Step-by-step explanation:
2. 12-8+4+9x(40+4)
12-8=4
4+4=8
8+ 9x(40+4)
add 40+4=44
8+9x(44)
396x+8
the is the answer
3. (18-9)×4+8+35-5
add 8+35=43-5=38
(18-9)×4+38
4 times 18 equal 72
-9 times 4 equal -36
72-36+38
the answer is 74❤
hope this helps
Answer:
2 < x < ∞
Step-by-step explanation:
We want where the value of y is less than zero
The value of the graph is less than zero is from x=2 and continues until x = infinity
2 < x < ∞
First, take two points from the graph. Call these points (a, b) and (c, d).
Next, find the slope. You can find this by doing (b-d)/(a-c).
Call the slope m. You will need this later.
Make an equation in slope intercept form (y = mx + b).
Now, take one of the points, and plug it into the equation.
mx + b has the same m as the slope.
From here, you can figure out b (the y-intercept).
To make a system, you do the same thing, but find where it is greater and lower.
Answer:
Step-by-step explanation:
The parametric equations are described below:
and 
The slope-intercept equation is constructed by eliminating t from both formulae:
and
