Answer:
t=−3 or t=−12
Step-by-step explanation:
Step 1: Subtract -36 from both sides.
t2+15t−(−36)=−36−(−36)
t2+15t+36=0
Step 2: Factor left side of equation.
(t+3)(t+12)=0
Step 3: Set factors equal to 0.
t+3=0 or t+12=0
t=−3 or t=−12
The domain is the x-values u insert to get corresponding y-values. In other words, the domain is the boundaries for which u can enter x valies. In this graph, we can see that the function continues infinitely upwards, not vertical shifting a bit to the sides. This means that the domain is all x belonging to the set R, since for any x value, we will get a corresponding point on the graph. For the range, it is simply the range of the y-values. From the graph, teh range is -4
The decimal equivalent of 1/4 inch is 0.25 inches
5x+2y=29
x+4y=13
Let's eliminate y;
To do so, multiply equation1 by 2;
10x+4y=58
x+4y=13
Subtract equation II from equation I to get;
9x=45
x=5
To solve for y, replace value of x in equation II,
x+4y=13
5+4y=13
4y=8
y=2

Answer:
- common denominator: (x² -4)
- simplified complex fraction: (2x +1)/(9 -2x)
Step-by-step explanation:
It is helpful to remember the factoring of the difference of squares:
a² -b² = (a -b)(a +b)
__
Your denominator of (x² -4) factors as (x -2)(x +2). You will note that one of these factors is the same as the denominator in the other fraction.
