PLZ I NEED HELP BUT PLZ EXPLAIN WHEN YOU ANSWER
Natalija [7]

Answer:

Step-by-step explanation:

Let's convert this statement into a system of two equations

3 * (cost of a liter of milk) + 5 * (cost of a loaf of bread) = $11

4 * (cost of a liter of milk) + 5 * (cost of a loaf of bread) = $10

cost of a liter of milk = x

cost of a loaf of bread = y

3x + 5y = 11

4x + 4y = 10

You can now solve this using either substitution or elimination

I'll use elimination. Let's say I want to get rid of the x first. I need to choose numbers to multiply by the top and bottom equations to eliminat the x's. The easiest way to do this is to multiply them by each other. So we'll multiply the top by 4 and the bottom by 3. We'll need to make sure the signs are opposite as well so I'll make that a negative 3 on the bottom.

4 * (3x + 5y = 11)

-3 * (4x + 4y = 10)

12x + 20y = 44

-12x - 12y = -30

Now add straight down

0x + 8y = 14

8y = 14

y = 14/8 = $1.75

Now we can plug this back in to either equation  to find the x. I'll choose the second equation

4x + 4*(1.75) = 10

4x + 7 = 10

4x = 3

x = 3/4 = $0.75

So, cost of a liter of milk = x = $0.75

and cost of a loaf of bread = y = $1.75

Which of the following options is a Pythagorean Identity
alexdok [17]

None of them really, but C is equivalent to the Triognometric Pythagorean Theorem:


(\sin x + \cos x)^2 = 1 + 2 \sin x \cos x


\sin^2 x + 2 \sin x \cos x + \cos ^2 x = 1 + 2 \sin x \cos x


\sin^2x + \cos ^2x = 1


That's the Trigonometric Pythagorean Theorem


Answer: C

Use the distributive property to write an expression that is equivalent to: 3(x + 5)
lana [24]

Answer:

3x=15

Step-by-step explanation:

Here's what I found on google about the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

3(x+5)

distribute the numbers-  3(x)+3(5)

solve-  3*5=15

3x+15

Write an equation of the parabola in vertex form that passes through (0, −24) and has vertex (−6, −12)
Elenna [48]
The general equation is y-k=a(x-h)² where (h,k) is the vertex.

So in this case we have y+12=a(x+6)².

Plug in x=0, y=-24: -12=36a, and a=-⅓. Therefore y+12=-⅓(x+6)².
