Answer:

D or answer 4 y=-5/2x+7

Step-by-step explanation:

Well we can first start of by finding the y-intercept.

Note that when x=0, you can find your y-intercept.

Knowing this, and looking at the table, 7 is the y-intercept because when y=7, x=0.

So we can eliminate choices 'a' and 'c,' or answers 1 and 3, because they have the y-intercept as -7, when it's just 7.

Please know that in the equation:

y = mx + b

y = y-coordinate or any given point

mx = slope

b = y-intercept

Now we must find slope

To find the slope we need to do:

(y2 - y1) / (x2 - x1) or rise/run

The two coordinates I choose to use is (0, 7) and (6, -8).

(-8 - 7) / (6 - 0) = -5/2

-5/2 is the slope

Finally, look for an equation that has 7 as the y-intercept and -5/2 as the slope.

Answer: D or answer 4

puteri [66]

I hope this helps you

y=x^2-10x+35

y=x^2-10x+25+10

y-10=(x-5)^2

y=(x-5)^2+10

h= -(-5)=5

Benji wrote the expression below to match the description "three less than the quotient of a number and nine" he wrote “3-n/9”ex

bulgar [2K]

Benji’s error is that the division should happen BEFORE subtracting 3. 3 should be subtracted from the quotient.

The correct response should be: (n/9)-3

25. Algebraically determine whether the function k(x) = x6 - x2 + 7 is odd, even, or neither. Explain your

alekssr [168]

Answer: The function is EVEN.

Step-by-step explanation:

For this exercise it is important to remember that:

1. A function f(x) is even if and only if:

$f(-x) = f(x)$ for all "x"

2. A function f(x) is odd if and only if:

$f(-x) = -f(x)$ for all "x"

So knowing that, and given the following function k(x):

$k(x)=x^6 - x^2 + 7$

You can plug $-x$ in for "x", order to know if this is even. Then, you get:

$k(-x)=(-x)^6 - (-x)^2 + 7\\\\k(-x)=x^6-x^2+7$

Therefore, since:

$f(-x) = f(x)$

You can determine that that the given function $k(x)=x^6 - x^2 + 7$ is Even.
