D, Each x value has one and only one y value.; This is because if an x-value repeats itself then it is not a function. You can test this on a graph by drawing a vertical line on it. If the vertical line intercepts the line more than once anywhere on the graph, then it is not a function.

Answer:

Each x value has one and only one y value.

Step-by-step explanation:

y = f(x) can be called a function if, and only if

f(a) = f(b) means that a = b.

That is, each x value has one and only one y value.

y = 4 - 6x

f(a) = f(b)

4 - 6a = 4 - 6b

6b = 6a

b = a

So the correct answer is:

Each x value has one and only one y value.

As an estimation we are told £3 is €4.
vova2212 [387]

Answer:

To solve the above problem we will use the unitary method as follows

As estimated  If £ 3 is equivalent to € 4

Then, £ 1 will be equivalent to = € \frac{4}{3}

£ 64.60 will be equivalent to = € \frac{4}{3} \times 64.60 = 1.3333 \times 64.60 = 86.1311

Now you have to round the answer up to 2 decimal points to get the final answer

€ 86.1311 ≈ € 86.13

Thus, £ 64.60 is approximately equal to  € 86.13.

Can someone answer this for me? ty
Fiesta28 [93]

Answer:

The intercepts are the locations where the line touches the x-axis and y-axis.

This question is asking for the coordinates for each of those locations, which would be:

(3, 0) for x-intercept location

(0, -10) for y-intercept location

The easy way to remember how to find coordinates is that the x is 'running', and the y is 'jumping', so the x coordinate comes before the y coordinate when finding sets like the ones above.

Round to the nearest gram
earnstyle [38]

Alright, so after a half-life, half of the previous number would be left. So basically,

180 g ← 0 half lives

90 g ← 1 half life

45 g ← 2 half lives

22.5 g ← 3 half lives

11.25 g ← 4 half lives


Therefore, the answer is 11.25 grams

Leno4ka [110]

Answer:

The correct option is;

C) AA Similarity Postulate

Step-by-step explanation:

The given parameters are;

BE║CD Given

∠A is congruent to ∠A Reflective property

∠ACD is congruent to ∠ABE Corresponding angles formed by parallel lines and a transversal

∠ADC is congruent to ∠AEB Corresponding angles formed by parallel lines and a transversal

ΔABE ~ ΔACD AA Similarity Postulate

When two angles of one triangle are equal to the corresponding two angles of another triangle, given that the third angle of both triangles are also equivalent based on sum of angles of a triangle postulate, the two triangles are said to be similar based on Angle-Angle (AA) Similarity Postulate.
