Answer:

The equation is y=-4x+103

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

y is the amount left in the saving account

x is the number of weeks

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=-\$4\ per\ week --> is negative because is a decreasing function

The y-intercept or initial value is

b=\$103

substitute

y=-4x+103

Point A is located at (2, 8) and point B is located at (8, 5). What point partitions the directed line segment ​ AB⎯⎯⎯⎯⎯ ​ into
djverab [1.8K]

Answer:

(3 1/2, 7 1/4)

Step-by-step explanation:

When the segments have the ratio 1:3, the shorter segment is 1/(1+3) = 1/4 of the total length.

The point P that divides the length that way will be ...

... P = A + (1/4)(B - A)

... = A - 1/4A + 1/4B

... = (3A +B)/4

... = (3(2, 8) +(8, 5))/4 = (14/4, 29/4)

... P = (3 1/2, 7 1/4)

A soccer field is 100 yd wide and 130 yd long. find the length of the diagonal of such a field. give an exact answer as a radica
Misha Larkins [42]
We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units

the answer is
the length of the diagonal is 10√269 units  or 164.012 units

A circle is shown. Secants E G and D G intersect at point G outside of the circle. Secant E G intersects the circle at point F a
USPshnik [31]

Answer:

Step-by-step explanation:

The formula we need here is

6(6+x)=5(5+x+3)

which simplifies to

6(6+x)=5(8+x)

which simplifies to

36 + 6x = 40 + 5x and

x = 4

So DG = 5 + 4 + 3 which is 12

Please help me with this!!!!!
vekshin1

Answer:

y = 4

Step-by-step explanation:

Note that A and B have the same x-coordinate:  1.  This means that AB is a vertical line through x = 1.  The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5.  Thus, it's just y = 4.

Review:  y = 4 bisects AB and represents a horizontal line.
