Answer:
Step-by-step explanation:
(-7 + 3)/(6 + 6) = -4/12 = -1/3
y + 3 = -1/3(x + 6)
y + 3 = -1/3x - 2
y = -1/3x - 5
Answer:
D. 25a² +60a +36
Step-by-step explanation:
You have memorized the form ...
(p +q)² = p² +2pq +q²
so you can write down immediately the result for p=5a and q=6:
(5a)² +2(5a)(6) +6² = 25a² +60a +36
You know that the standard form for linear equation is Ax+By=C
Rearrange the equation as follows;
6x+8y=-4
Hope I helped :)
Answer:
i think answer is option a.
Step-by-step explanation:
after we get the simplest form, we find that only the first two options are applicable. then we conclude x can be equal to five, so we can eliminate the second option. therefore the first option, option a., is the right answer.
Answer:
Step-by-step explanation:
Hello,
<em>"Ray says the third-degree polynomial has four intercepts. Kelsey argues the function can have as many as three zeros only."</em>
We know that Kelsey is right, a polynomial of degree 3 has maximum 3 zeroes, so it means that the graph of this polynomial has maximum 3 x-intercepts.
<u>So how Ray can be right too?</u>
we need to think of y-intercept, if we add the y-intercept then Ray can be right too,
as you can see in one example below
there are 3 x-intercepts and 1 y-intercept.
This being said, Ray is not always right. For instance
has only 1 zero (multiplicity 3) its graph has only 1 intercept in the point (0,0)
hope this helps
