Answer:

well let’s break this down

Let’s make type a coffee “a”

And type b coffee “b”

a is 4.35

b is 5.70

We knwo that b is twice as many as a

The total is 614.25

So we can do soemthing like this

4.35a+ (5.70b)2 = 614.25

Now solve

If we simplify its really

4.35a+11.40b =614.25

I like multiply by a 100 to get rid of decimals

435a+1140b=61425

Here we can go 2 ways

We can isoalte a or b

im gonna isloate b

so it would be (61425-435a)/1140 =b

Now we can use that as a subsitube to find a

Now we can just do this

435a +1140(61425-435a)/1140 = 61425

Pop it through an algebra calculator (just search up math pa..Pa and copy paste it, edit if needed) and then you’d get your answer

A’B’C’ is a dilation image if ABC which is the correct description of the dilation
Sav [38]

Answer:

The dilation is an enlargement

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate

Let

z------> the scale factor

so

z=\frac{A'C'}{AC}

substitute the values

z=\frac{2+8}{2}

z=\frac{10}{2}=5

The scale factor is greater than 1

therefore

The dilation is an enlargement

What’s the equation of the line that passes through (2,3) and is parallel to the line 12x-5y=2
TiliK225 [7]

12x-5y=2

-5y=2-12x

y=-2/5+12/5x

should know the m=12/5

and (2,3) bring them to the line equation:

3=12/5x2+b

6/5+b=3

b=3-6/5

b=9/5

y=12/5x+9/5

Which means the answer is not in the choices.
