Answer:

15 dollars off is the better deal or "A is 2 dollars better."

Step-by-step explanation:

Let's take it step-by-step and scout out each possibility:

Since the jeans are $65, we can first try what we get when we take 15 dollars off:

- $\left\begin{array}{cc}65&\\15\end{array}\right$

$___________$ _______

$50$ So 50 is what we get for the first possibility.

Now let's try 20% off:

$\frac{20}{100}$ · $65$ = 13. Now, remember, that 13 isn't our final answer. 13 is the amount off. So 65 - 13 = 52 is what we get for the second possibility.

Evaluate:

So 15 dollars off is the better deal or "A is 2 dollars better."

A parabola has a vertex at (4, 0) and passes through the point (6, 1). Which of the following is the equation of this parabola i

Doss [256]

Easy

y=a(x-h)^2+k
vertex is (h,k)
we know that vertex is (4,0)
input that point for (h,k)
y=a(x-4)^2+0
y=a(x-4)^2
passes thorugh the point (6,1)
input that point to find a
1=a(6-4)^2
1=a(2)^2
1=a(4)
divide both sides by 4
1/4=a

thefor the equation is
y=(1/4)(x-4)^2
or
y=(1/4)x^2-2x+4

I just learned this today and it’s a little confusing , is there anyone that could explain how to do these problems for me ?

evablogger [386]

Step-by-step explanation:

I'll do the first problem as an example.

∠P and ∠H both have one mark. That means they're congruent.

∠T and ∠G both have two marks. So they're congruent.

∠W and ∠D both have three marks. So they're congruent.

So we can write a congruence statement:

ΔPTW ≅ ΔHGD

We can write more congruence statements by rearranging the letter, provided that corresponding pairs have the same position (P is in the same place as H, etc.). For example:

ΔWPT ≅ ΔDHG

ΔTWP ≅ ΔGDH
