You should use point-slope form: y-y1 = m(x-x1)
y+9 = 4(x)
y-4x=-9
4x-y=9 (B)
You need to put the Answers and picture/problem before asking someone to answer it.
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
<span>1/2+(-2/3)
Multiply until both fractions have the same common denominator
3/6 - 4/6
Subtract the numerator but NOT the denominator
Final Answer: -1/6</span>
It’s 9! 9 is the square root of 18
