Answer:

Step-by-step explanation:

Using the sentences "One thing parents should not be worried about vaccinating their kids; still, the debate rages on," and the sentence "The real culprit undermining the public's safety is a baseless claim that vaccinations lead to autism." Using the fact that it is baseless, we can deduce that the author thinks it is not something to worry about. This means that we can rule out B and C. Also, A is not correct because the passage rarely mentions about this, so the answer is D.

Which expression is equivalent to 6(2m – 1) – 4(m + 8)?

Tju [1.3M]

6(2m - 1) - 4(m + 8)

We can use the distributive property here.

12m - 6 - 4m - 32

Simplify.

<h3>8m - 38 is the simplified form of the original expression. </h3>

This question is pretty confusing in the way that i'm not entirely sure what it wants the answer to be, but i'll do my best.

i used the simple interest formula to come up with the equations, and the formula is I = PRT, (I) being interest, (P) being the amount, (R) being the rate of interest, (T) being the time, in months

b = the balance on the customer's account
c = service charge
t = number of months

if b > 1000, then c = b*.008t
if b </= to 1000, then c = b*.012t
if b < 50, then c = t
if b = 0, then c = 0

it looks really confusing but i'm hoping it's lining up with what you're learning and not completely ?????

i created the restrictions with the inequalities based on the given information of what happens when a balance exceeds 1000, is less than 1000, is less than 50, and is 0.

i used the remainder of the given information in the problem to get the equations -- the interest rate for b > 1000 is 0.8%, which is .008, b </= 1000 is .012, and so on. i hope this wasn't too terribly confusing, and let me know if you have any questions about how i came up with the equations!!

Answer:

C.g(x) = 5x²

Step-by-step explanation:

To find the equation for the function g(x), use the format for a quadratic equation. Without any up/down and left/right shifts, the form is y = ax².

Substituting "x" and "y" into the equation tells you if a point is on the graph.

"a" tells you the vertical stretch (greater than 1) or compression (greater than 0, less than 1).

In f(x) = x², a = 1 even though it's not written.

Use the point (1, 5) on g(x) and substitute it into the form for a quadratic function. Remember points are (x, y), so x = 1 and y = 5.

g(x) = ax²

y = ax² In function notation, g(x) replaces the "y". Switch it back to "y".

5 = a(1)² Substitute x = 1 and y = 5

5 = a(1) Solve the exponent first. (1)² = 1

5 = a When you multiply "a" by 1, the answer is just "a".

a = 5 Solved for "a". Put variable on left side for standard formatting.

With the quadratic form, substitute "a" into g(x).

y = ax²
