Answer:

x=14c+2

Step-by-step explanation:

$\frac{2}{7} (x-2)=4c \\\frac{2}{7}x-\frac{4}{7} =4c\\\frac{2}{7}x=4c+\frac{4}{7}\\\frac{2}{7}x= \frac{28c+4}{7} \\2x=28c+4\\x=14c+2$

Approximate the distance between (0, -5) and (4, 1) to the nearest tenth, if necessary.

frutty [35]

Answer:

7.7

Step-by-step explanation:

To solve this question we must use Pythagoras (a²+b²=c²) Let those two dots be A and B respectively.Imagine a line is drawn that pases through both dots,

Imagine that the line given is the hypotenuse (the longest side of a right-angled triangle) of a right-angled triangle and the other sides as a line from A going to the right, and a line from B going downwards, making the final vertexes for the triangle at coordinates: 0,-5 4,1 and 4,-5 (the vertex we made). now we find the lengths for the sides: 4 and 6 so we use these to plug them into pythagoras's equation:

4²+6²=c²

24+36=c²

√60=c

c=7.74....

But all we need is until the tenths so the answer is 7.7 (as the hundredths digit, 4, rounds down)

Graph the relation and it's inverse. Use open circles to graph the points of the inverse

joja [24]

Step-by-step explanation:

We are given a set of points (0,3), (4,2), (9,7) and (10,-1) representing a function.

It is required to graph the function and its inverse.

As we know that, the inverse of a function is reflected by y=x line on the graph.

So, in order to find the inverse we have to replace the co-ordinate (x,y) by (y,x).

Then the points (3,0), (2,4), (7,9) and (-1,10) represents the inverse of the function.

So, after plotting all the points of the function and its inverse, we get the following graph, where figure 1 is of the function and figure 2 is of its inverse.

It takes me 15 seconds to swim half a length of the pool. How many lengths can I swim in 10 minutes?

nordsb [41]

30 seconds for the whole length, so 1 min for 2 lengths meaning 2 • 10 = 20 lengths

A model car has a scale factor of 1/64 The diameter of a tire on the model is 0.39 inches. So, the diameter of the tire on an ac

Blizzard [7]

This is the concept of scale factors, given that the length of the model which has been modeled by scale factor 1/64 is 0.39 inches, then the actual diameter will be:
scale scale factor=(model diameter)/(actual diameter)
where:
actual diameter=(model diameter)/(scale factor)
=0.39/(1/64)
=24.96 inches
