PLEASE HELP MEEEE I NEED HELP PLEASE NO ONE WILL HELP ME

Mathematics
1 answer:
nevsk [136]2 years ago
3 0

Answer:

a. From x = -2 to x = 0, the average rate of change for both functions is negative

d. The quadratic function, y = x², has an x-intercept at the origin

Step-by-step explanation:

From x = -2 to x = 0, the rate of change is negative because both functions are going in a downward slope. The quadratic function y = x² touches the x-axis right at (0, 0), meaning it has an x-intercept at the origin.

The second answer is incorrect because y = x² does not intersect the other parabola at (2, 3). The third is incorrect because y = x² + 3 does not even touch the x-axis. The fifth is incorrect because the rate of change is negative, not positive. Finally, the sixth is incorrect because y = x² + 3 does not intersect the other parabola at (2, 7). Hope this helps! Feel free to ask any questions!

m = Miguel Indurian titles amount        l = Lance Armstrong titles amount

they both won titles to the tour de france, if we add all together, they sum up to 12 for both of them
so.. whatever "m" and "l" are, we could say that m + l = 12

now... Miguel won 2 fewer than Lance, so, whatever "l" is, m = l - 2
thus    \bf \begin{cases}
\boxed{m}=l-2\\\\
m+l=12\\
----------\\
\left( \boxed{l-2} \right)+l=12
\end{cases}

solve for "l", to see how many Lance won

how many did Miguel win? well,  m = l - 2

c = mgs amount in 12oz cup of regular coffee at starbucks
d = mgs amount in 12oz cup of regular decaffeinated coffee at starbucks

we know the regular coffee cup, has 13 times more than the decaf, same 12ouncer

thus whatever "c" and "d" are, we know that c = 13d
both 12ouncers put together, yield 280mgs of caffeine

so, one could say that whatever "c" and "d" are, c + d = 280

thus      \bf \begin{cases}
\boxed{c}=13d\\\\
c+d=280\\
----------\\
\left(  \boxed{13d}\right)+d=280
\end{cases}

solve for "d" to see how much is in the decaffed cup

the regular coffee cup?  well c = 13d

The school marching band has a budget of up to $750 to cover 15 new uniforms and
PolarNik [594]

a. The inequality 15x+300≤750 represents the situation.

b. It means that the band can spend at most $30 on each uniform without exceeding the budget.

Step-by-step explanation:

Given,

Budget = $750

Competition fee = $300

Uniforms to make = 15

Let,

x be the amount for each uniform.

a.  Write an inequality to represent this situation.

Uniforms to make * Cost per uniform + Competition ≤ Budget

15x+300 ≤ 750

The inequality 15x+300≤750 represents the situation.

b.  Solve the inequality and describe what it means in the situation.

15x+300\leq 750\\15x+300-300\leq 750-300\\15x\leq 450

Dividing both sides by 15

\frac{15x}{15}\leq \frac{450}{15}\\x\leq 30

It means that the band can spend at most $30 on each uniform without exceeding the budget.
