Answer:

Square root of 87.35 will be plotted between 9 and 10 as shown below.

Step-by-step explanation:

We are given that, 'The number line is numbered in tenths'

Also, the square root of 87.35 is given by,

$\sqrt{87.35}=9.4$

That is, we have to plot the point 9.4 on the number line numbered in tenths.

As, 9.4 will lie between the points 9 and 10.

Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.

kozerog [31]

Answer:

(x,y)= (-1,-4)

Step-by-step explanation:

y=4x

put this value of y in 3x-y=1

3x-4x=1

-x=1

x= -1

y=4(-1)

y= -4

So (x,y) ordered pair is (-1,-4)

Which equation is the inverse of y = 16x2 + 1?

Llana [10]

Answer:

$y=\frac{\sqrt{x-1} }{4}$

Step-by-step explanation:

The given equation is

$y=16x^2+1$

For this function to have an inverse, we must restrict the domain, say $x\ge0$

We interchange x and y to get,

$x=16y^2+1$

We now make y the subject to get;

$x-1=16y^2$

We divide through by 16 to get;

$\frac{x-1}{16}=y^2$

We now take the square root of both sides to get;

$\pm \sqrt{\frac{x-1}{16}}=y$

$y=\pm \frac{\sqrt{x-1} }{4}$

Since $x\ge 0$ , the inverse function is

$y=\frac{\sqrt{x-1} }{4}$

If P = (-2,-1) and Q = (4,3) are the

Ivanshal [37]

Answer:

Step-by-step explanation:

P(-2,-1) and Q(4,3)

average of x-coordinates = (-2+4)/2 = 1

average of y-coordinates = (-1+3)/2 = 1

midpoint of PQ: (1,1)

distance between midpoint and Q = √((4-1)²+(3-1)²) = √13

(x-1)² + (y-1)² = 13
