In other words, y-2 goes in the first box and 5 goes in the second box.
=================================================
Work Shown:
y^2 - 4y - x + 9 = 0
y^2 - 4y + 9 = x
x = y^2 - 4y + 9
x = y^2 - 4y + 4 + 5 .... rewrite 9 as 4+5
x = (y^2-4y+4) + 5
x = (y-2)^2 + 5 .... apply the perfect square factoring rule
So we'll have y-2 go in the first box and 5 goes in the second box
note: One version of the perfect square factoring rule says (a-b)^2 = a^2-2ab+b^2.

Answers
Answer:
y = 2x + 4
Step-by-step explanation:
y2 - y1/ x2- x1
= 8 - 6 / 2 - 1
= 2
So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.
y = 2x + b
8 = 2(2) + b
8 = 4 + b
4 = b
The y-intercept is 4.
If we put one of the values like the x in the equation, we should get the y value.
y = 2x + 4
y = 2 (3) + 4
y = 6 + 4
y = 10

5x + 5x = 10x
Combine like terms: 5x + 5x = 10x
10x = 10x
Add '-10x' to each side of the equation.
10x + -10x = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 10x + -10x
Combine like terms: 10x + -10x = 0
0 = 0
Step-by-step explanation:
Answer: 5x+5x=10x²
10x=10x²
10x²+ -10x²=0
10x+-10x²=0
10x(1+ -1x)=0

Someone :) is there anyone know what is the answer?
Answers
Answer:
answers are below
Step-by-step explanation:
a. -6 ≤ 3x < 15
steps in order to solve:
-6 ≤ 3x
= -6/3 ≤ 3x/3
= -2 ≤ x
3x < 15
= 3x/3 < 15/3
= x < 5
=> -2 ≤ x < 5
b. -3 < 2x - 1 < 7
steps in order to solve:
-3 < 2x - 1
= 1 - 3 < 2x - 1 + 1
= -2 < 2x
= -2/2 < 2x / 2
= -1 < x
2x - 1 < 7
= 2x - 1 + 1 < 7 + 1
= 2x < 8
= 2x/2 < 8/2
= x < 4
=> -1 < x < 4
c. 7 < -3n + 1 ≤ 13
steps in order to solve:
7 < -3n + 1
= -1 +7 < -3n + 1 - 1
= 6 < -3n
= 6/-3 < -3n/-3
= -2 > n
-3n + 1 ≤ 13
= -3n + 1 - 1 ≤ 13 -1
= -3n < 12
= -3n/-3 < 12/-3
= n > -4
=> -4 < n < -2

F is directly proportional to a.
If F = 28 when a = 7 find,
F when a = 10
Answers
Answer:
Step-by-step explanation:
a=10
Step-by-step explanation:
The question can be interpreted as
F∝a
If we introduce proportionality constant k, we have
F= k.a
28= k. 7
k= 28/7
k= 4
Then the equation can be written as
F= 4.a
To find, a when F = 40?
F= 4.a
40=4 × a
a= 40/4
a= 10
Answer:
F = 40
Step-by-step explanation:
Given F is directly proportional to a then the equation relating them is
F = ka ← k is the constant of proportion
To find k use the condition F = 28 when a = 7 , then
28 = 7k ( divide both sides by 7 )
4 = k
F = 4a ← equation of proportion
When a = 10, then
F = 4 × 10 = 40

find the area of the minor sector
1 r=9cm,tita=70
Answers
Answer:
The area is 49.5 cm^2
Step-by-step explanation:
To find the area of the sector, we are going to use the formula for the area of a sector
Mathematically, we have this as;
A = theta/360 * pi * r^2
r = 9 cm and theta = 70
Substituting these values
A = 70/360 * 3.142 * 9^2
A = 49.5 cm^2

This compensation strategy may increase the supply of candidates, increase selection rates of qualified acpplicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.
