Mathematics

-3(5y - 4) ≥ 17

-15y + 12 ≥ 17

-15y ≥ 5

y ≤ -1/3

To graph this inequality, place a closed circle at the line one to the left of 0. Then, draw a line above or on the number line with an arrow that points to the left.

Hope this helps!! :)

Answer:

y≤-1/3 (fraction)

And on the number line it will start from -1/3 (-0.333) and go less than -1/3 ( to the left, and it will be shaded

Step-by-step explanation:

First we expand the brackets, making it -15y+12≥17

Then we move 12 to the other side, making it negative, -15y≥17-12

Simplify, -15y≥5

Then we divide on both sides to isolate y, flipping the greater than sign to less than because when you divide or multiply by a negative number, the sign flips. y≤5/-15

Then we simplify by dividing the fraction by 5, making it -1/3. y≤-1/3

If you have any doubts, inform me

What is the axis of symmetry of the function f(x) = –(x + 9)(x – 21)?
ludmilkaskok [199]
First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms

anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.

Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.

The axis of symmetry is 6

Use the distributive property to remove the parentheses. -6(5y-2u-3)
olga55 [171]
<h2>Answer: -30y + 12u + 18 </h2>

<h3>Step-by-step explanation:</h3>

    <em> by multiplying each term in the parentheses by the term outside</em>

-6(5y-2u-3) = (-6 × 5y) + (-6 × - 2u) + (-6 × -3)

                   = -30y + 12u + 18

a leatherback turtle swims at a constant rate of 2.5 kilometers per hour, at its constant rate of speed how long will it take fo
LekaFEV [45]
Hello there!

So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

\boxed{10.0 \left \{ {{2.5+2.5=5.0} \atop {2.5+2.5=5.0}} \right.}

We would have to count how many ("2.5's" they are above.)

We count only 4.

I would take this turtle 4 miles to swim 10 kilometers.
