The diagram is a "mapping diagram" that describes a function? The function pairs numbers from the set on the left with numbers from the set on the right. "Domain" refers to the numbfers on the left, where the arrows come FROM. (Some people describe this as a mapping of x to y, with x on the left and y on the right.) The answer is B.

Indicate in standard form the equation of the line through the given points.

Molodets [167]

Answer:

x-y=4

Step-by-step explanation:

(y+4)/(1+4) = x/5

(y+4)/5 = x/5

y+4 = x

-x+y= -4

x-y = 4

What is the center and radius of the circle that has the equation x+72+y-42=49? Explain.

balu736 [363]

Answer: The center is (-7, 4) and the radius is 7.

Step-by-step explanation:

The equation for a circle usually is:

(x - a)^2 + (y - b)^2 = R^2

where R is the radius, and (a, b) is the center of the circle.

I guess that the equation in this case is:

(x + 7)^2 + (y - 4)^2 = 49

then, in this case we have:

a = -7 and b = 4, then (a, b) = (-7, 4)

this means that the center of our circle is in the point (-7, 4)

and we know that:

R^2 = 49

R = √49 = 7

Then the radius is equal to 7.

The state fair charges $14 for

Scrat [10]

Answer:

$s=6r+14$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$s=mr+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=\$6\ per\ ride$

The y-intercept is equal to

$b=\$14$

substitute the given values

$s=6r+14$
