Answer:

Step-by-step explanation:

Step 1. Substitute all the letters for their values and since in algebra when you don't write the times sign it means you wanna times it so what you would do is 3 x 3 x 5 x 2 = 90.

Step 2. Substitute the <em><u>a</u></em> in 10a for 3 then times since there is a "hidden" times symbol. Which then would be 10 x 3 = 30

Step 3. When we say something over something it means to divide so what we do is divide the first answer by the second answer which is: 90/30 which is 3.

Hope this helps, and if you need further explanation I can do so. :)

How to solve a teo step inequality

prohojiy [21]

Answer:

Use the order of operations in reverse and remember that dividing or multiplying by a negative reverses the inequality

Explanation:

The order of operations is PEMDAS in reverse it is PESADM ( if you lose your cell phone in PE you are a SAD M(am)

Remember multiply or dividing by a negative reverses the value of the quality being divided or multiplied.

Just do the order of operations in reverse as in solving an equation always doing the opposite. Then remember to reverse the inequality sign whenever the inequality is multiplied or divided by a negative.

Answer-

y=-2x+2

It starts at +2 so that is the b

And -2x is how you move so that is the m

That's how I was taught and how I remember it lol hope it helped ik it wasn't the best its 12 am here soo I be tired

Y = 2x2-12x+25 write in vertex form and show work

nalin [4]

The vertex form of y = 2x² - 12x + 25 is y = 2(x - 3)² + 7

Step-by-step explanation:

The vertex form of a quadratic function is y = a(x - h)² + k, where

(h , k) are the coordinate of the vertex point
a is the leading coefficient (coefficient of x²)
If y = ax² + bx + c, then $h=\frac{-b}{2a}$
k = f(h) that means the value of y when x = h

∵ y = 2x² - 12x + 25

∵ y = ax² + bx + c

∴ a = 2 , b = -12 , c = 25

∵ $h=\frac{-b}{2a}$

∴ $h=\frac{-(-12)}{2(2)}$

∴ $h=\frac{12}{4}$

∴ h = 3

∵ k = f(h)

∴ k = f(3)

∵ y = 2x² - 12x + 25

- Substitute x by 3 to find k

∴ k = 2(3)² - 12(3) + 25

∴ k = 18 - 36 + 25

∴ k = 7

∵ The vertex form is y = a(x - h)² + k

∵ a = 2 , h = 3 , k = 7

∴ y = 2(x - 3)² + 7

The vertex form of y = 2x² - 12x + 25 is y = 2(x - 3)² + 7
