Answer:

-1/2

Step-by-step explanation:

You use rise and run to figure it out. Pick any point on the line and either go up one to the left two or go down one to the right two

Fill in the table using this function rule<br><br> Y=5x-19

andreyandreev [35.5K]

4) y = 5x - 19
y = 5(4) - 19
y = 20 - 19
y = 1

5) y = 5x - 19
y = 5(5) - 19
y = 25 - 19
y = 6

8) y = 5x - 19
y = 5(8) - 19
y = 40 - 19
y = 21

10) y = 5x - 19
y = 5(10) - 19
y = 50 - 19
y = 31

Zoey wants to use her iPad throughout a 6-hour flight. Upon takeoff, she uses the iPad for 2 hours and notices that the battery

lilavasa [31]

Answer:

The answer is c. 8 hours

Step-by-step explanation:

Since her battery dropped 25% in 2 hours then for it to drop 100% would take 8 hours.

25%+25%+25%+25%= 100%

so with this logic

25%= 2 hours

2+2+2+2=8

Hoped this helped !

Cheers, Z

Answer:

No solution

Step-by-step explanation:

We have

$\sum_{x=8}^{4}x^2 + 9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

For the sum it is not correct to assume

$\sum_{x=8}^{4}x^2= 8^2 + 7^2+6^2+5^2+4^2 = 64+49+36+25+16 = 190$

Note that for

$\sum_{x=a}^b f(x)$

it is assumed $a\leq x \leq b$ and in your case $\nexists x\in\mathbb{Z}: a\leq x\leq b$ for $a>b$

In fact, considering a set $S$ we have

$\sum_{x=a}^b (S \cup \varnothing) = \sum_{x=a}^b S + \sum_{x=a}^b \varnothing$ that satisfy $S = S \cup \varnothing$

This means that, by definition $\sum_{x=a}^b \varnothing = 0$

Therefore,

$\sum_{x=8}^{4}x^2 = 0$

because the sum is empty.

For

$9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

we have other problems. Actually, this case is really bad.

Note that $\cos^2(\infty)$ has no value. In fact, if we consider for the case

$\lim_{x \to \infty} \cos^2(x)$ , the cosine function oscillates between $[-1, 1]$ , and therefore it is undefined. Thus, we cannot evaluate

$9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

and then

$\sum_{x=8}^{4}x^2 + 9\left(\dfrac{\cos^2(\infty)}{\sin^2(\infty)} \right)$

has no solution

Solve the system. I need help solving these problems. but I have to show my work

Yuki888 [10]

3x - 5y = 7
2x + 3y = 11

multiply the first equation by 2 and the second by -3:-

6x - 10y = 14
-6x - 9y = -33 Adding these 2 equations we eliminate the term in x:-
-19y = -19
y = 1
Substtute y = 1 in the first equation:_
3x - 5(1) = 7
3x = 12
x = 4

Answer is x=4,y=1 Answer

Second system of equation:-s

Here one equation is linear and the other is quadratic so we substitute fro y in the quadratic:-
From second equation y = 10x - 38, so substituting:-
10x - 38 = x^2 - 4x - 17

Gotta go right now . Sorry
