The answer is D because black model A1 are the least wanted
We have 2 denominators that we need to get rid of. Whenever there are the denominators, all we have to do is multiply all whole equation with the denominators.
Our denominators are both 2 and x+1. Therefore, we multiply the whole equation by 2(x+1)
Then shorten the fractions.
Distribute in all.
We should get like this. Because the polynomial is 2-degree, I'd suggest you to move all terms to one place. Therefore, moving 2x+2 to another side and subtract.
We are almost there. All we have to do is, solving for x by factoring. (Although there are more than just factoring but factoring this polynomial is faster.)
Thus, the answer is x = 3, -2
Answer:
x=-1
Step-by-step explanation:
The equation would be: (x + 6)^2 + (y + 3)^2 = 25
This equation will produce a circle. If you add the numbers inside the parenthesis to be squared, you can center of the circle. Thus, translating the shape.
Answer: The slope of the line a is 3/4
Step-by-step explanation:
1. The equation of the line has the following form:
Where m is the slope and b is the y-intercept.
2. As you can see in the graph attached, the line intersect the y-axis at 1, therefore:
b=1
3. So, to calculate the slope, susbtitute: the value of b into the equation of the line and any point of the line and then solve for the slope:
Let's pick the point (4,4), then the slope is:
