The value of x that fills the coordinate are 7 or -5

<h3>Distance between two points</h3>

The formula for calculating the distance between two points is expressed as:

D = √(x2-x1)² +(y2-y1)²

Substitute the given coordinates

10 = √(15-7)² +(1-x)²

100 = 8² +(1-x)²

(1-x)² = 100 - 64

(1-x)² = 36

1- x = -6

x = 7 or -5

Hence the value of x that fills the coordinate are 7 or -5

Answer:

Step-by-step explanation:

$(f\circ g)(x)=f(g(x))\\\\(f\circ g)(2) = f(g(2)) = f(2\cdot 2+3) = f(7)\\\\=4\cdot 7-1=\boxed{27}$

Rebecca must complete 15 hours of volunteer work. She does 3 hours each day. Write a linear equation in slope-intercept form to

ValentinkaMS [17]

Answer:

y = 15 hour - 3 hours/day x days

y = 15 - 3x

y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.

0 = 15 - 3x

3x = 15

x = 5 (Number of days she would have to volunteer)

Equation: y = 15- 3x

A translation along the vector (-2 , 7 ) maps point P to point Q. The coordinates of point Q are (4, -1 ) What are the coordinat

Artist 52 [7]

<span>A translation is simply a "moving" when it comes to a point. In this case, by adding (-2, 7) to the point P, we will find point Q. That is, x-2 gives Q's x-coordinate of 4 and y+7 gives Q's y-coordinate of -1. To start, x-2 = 4 gives an x of -6, and y+7 = -1 gives a y of -8. So, the original point P was located at (-6,-8).</span>
