Answer:
I believe the answer to #5 is $6.50.
Step-by-step explanation:
25.75-19.25=6.50
Answer:
Hello
Midpoints of (-6,4),(-1,-6)
P(a,b)=(x1+x2/2),(y1+y2/2)
=(-6+-1/2),(4+-6/2)
=(-7/2),(-2/2)
=(-7/2),(-1)
Midpoints of the segment with endpoints (-6, 4) and (-1,-6) are (-7/2),(-1)
Hope it helps you......
We are given quadratic x^2-2x-8.
Let us factor it by product sum rule.
According to product sum rule, we need to find the factors of -8 that add upto -2.
If we write all factors of 8, we get 8,4,2 and 1 factores.
So, we could choose -4 and +2.
Because -4+2 = -2 (sum) and -4*2=-8 (product)
x^2-2x-8
Splitting middle term into two terms -4x+2x
x^2-4x+2x−8
Factoring out gcf from each group.
x(x-4) +2(x- 4)
(x + 2)(x - 4)
So, we got factored form of the given euadratic (x + 2)(x - 4).
Reciprocal of it would be
.
Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.
So, you can go through each of your options to see which ones work with those rules.
A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2<span>

, menaing A is a fraction, which you can't have.
B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.
C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.
D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.
So,
C and
D are both written in Standard Form.
