Answer:

Please see below :)

Step-by-step explanation:

y - 5 = -(x + 11) + 2

y - 5 = -x - 11 + 2

y = -x - 11 + 2 + 5

y = -x - 9 + 5

y = -x - 4

54x + 15 = -3(3y + 1)

54x + 15 = -9y - 3

54x + 15 + 3 = -9y

54x + 18 = -9y

-6x - 2 = y

y = -6x - 2

Please let me know if I've done anything wrong!

5x^2-2x=2<br>help plsmmm

Answer:

Presumably you're solving for x here? Without further information we'll assume that.

With that in mind, x is approximately equal to 0.86 and -0.46

Step-by-step explanation:

Let's start by putting it in the usual ax² + bx + c format.

$5x^2- 2x = 2\\5x^2 - 2x - 2 = 0\\$

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

$25x^2 - 10x - 10 = 0\\$

Now we'll add 11 to both sides:

$25x^2 - 10x + 1 = 11\\$

Which makes the left side a perfect square:

$(5x - 1)^2 = 11$

And now we can solve for x:

$(5x - 1)^2 = 11\\\\5x - 1 = \sqrt{11} \\\\5x = 1 + \sqrt{11}\\\\x = \frac{1 + \sqrt{11}}{5}$

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.

That gives us two answers:

$x = \frac{1 + \sqrt{11}}{5}\\\\x \approx \frac{1 + 3.32}5\\\\x \approx \frac{4.32}5\\\\x \approx 0.86$ $x = \frac{1 - \sqrt{11}}{5}\\\\x \approx \frac{1 - 3.32}5\\\\x \approx \frac{-2.32}5\\\\x \approx -0.46$

I will give u brianliest

Answer:

1: $3$ × $2$

2: $y^6$

Step-by-step explanation:

Multiply the numbers: $y(^3^*^2)$

$3*2 = 6$

Write it without exponents:

$y * y * y * y *y *y$ so $6y$ .

$(y^3)^2$

Apply exponent rule : $(a^b)^c=a^b^c,$ assuming $a\geq 0$

$(y^3)^2=y^3^*^2$

$=y^3^*^2$

Multiply the numbers: $3 * 2 = 6$

$= y^6$

Hope I helped! If so, may I get Brainliest and a Thanks?

Thank you, have a good one! =)

I would appreciate if you answered!

Answer:

None of those options

Step-by-step explanation:

I just did the work myself and even ran it through a calculator but the correct answer isn't one of those options. Here's my work:

$-\frac{5}{6} =z+\frac{1}{8}\\-\frac{5}{8}-\frac{1}{8}=z\\-\frac{40}{48}-\frac{6}{48}=z\\-\frac{46}{48}=z\\-\frac{23}{24}$

I'd contact you teacher about that...it might be an error in their system (it's happened to me a few times before where the correct answer is marked as incorrect or isn't even an option)
