Complete the equation y - 4.....
First, we need to determine the slope as follows:



The equation is then calculated as thus:

This gives:

Open bracket

Add 4 to both sides




The sum of the numbers should total to 1. Let us say that
x is the missing number, therefore:
x + ¼ + ¼ + 1/5 = 1
x = 1 – ¼ - ¼ - 1/5
The numbers should have similar denominator:
x = 20/20 – 5/20 – 5/20 – 4/20
x = 6/20
<span>x = 3/10</span>
The expression would be written as:

n-3
N is any number. This expression means two-fifths of a number, subtract three. Now substitute 25 for n.

(25)-3
=10-3
=7
Answer:
Look below
Step-by-step explanation:
lets have -29 be y2 and -5 be x2
21 - (-)29
5 - (-)5
Subtracting a negative is just adding it so
21 + 29 50
5 + 5 10
50/10
this simplified, is 5/1 or 5
y=5x+b
now we need to find b, so we substitute y and y
x = 5
y = 21
21=5*5=b
5*5 is 25
now we need to get to 21
25 -4 is 21
b = -4
y=5x-4
Answer:
G(3, 1), H(2, 3)
Step-by-step explanation:
When D is the midpoint of EG, it means ...
D = (E + G)/2
or
G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)
Likewise, H is ...
H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)
