Answer:
a) (0,0), (-4, 1), (-1,2)b) NoneStep-by-step explanation:
There are two ways of solving similar problems. One- substitute x and y with respective coordinates and verify if the inequalities are correct. Two- graph the lines and see if the points are in the intersection zones.We'll go with the first method. Remember both inequalities should be correct for the same point to accept it as a solution.Given points

Answer:
a. all points are part of the solution set
b. no points are in the solution set
Step-by-step explanation:
Graphs of the two systems of inequalities are attached.
a) The red area on the graph is the solution. The two inequalities can be combined to one compound inequality:
x -1 < y < -1/2x +2
The two boundary lines intersect at x-1 = -1/2x +2 ⇒ x = 2, so there are no points in the solution set with x-values of 2 or greater.
All of the given points are in the solution set.
__
b) The green area of the graph is the solution. Solving each inequality for y gives ...
x -2y ≥ 4 ⇒ 1/2x -2 ≥ y
2x -y ≥ -1 ⇒ 2x +1 ≥ y
The allowed values of y must be less than or equal to the minimum of these limits. The limits have the same value at 1/2x -2 = 2x +1 ⇒ x = -2, so the solution set is the area below and right of that intersection point of the two boundary lines.
None of the given points are in the solution set.

Noticed how it forms a supplementary angle.
A supplmentary angle is basically two angles that added up to 180 degrees.
So we have:
64 + x = 180
Then we solve for "x", so "x" = 116.
Hope that makes sense :)

Harry buys a TV priced at £1200 plus 20% VAT.
He pays £300 deposit and the balance in ten equal monthly payments .
Calculate each monthly payment.
Answer:
114
Step-by-step explanation:
20% of 1200= 240
so total price is 1200+220=1440
he pays 300 beposit
1440-300=1140
now 1150 must be paid in 10 installments equally
11400÷10=114 is the answer
What is an equation of the line that passes through the points (-6, -2) and
(6,8)?
Answer:
y=5/6x+b
Step-by-step explanation:
use formula (y2-y1)/(x2-x1) to look for the slope:
(8-(-2))/(6-(-6))
=10/12
=5/6 (simplified)
then, use the formula y=mx+b to get the equation by substituting m and x, y to either (-6, -2) or (6, 8):
8=5/6(6)+b
8=5+b
3=b (subtract 5 on both sides)
equation:
y=5/6x+3

What are the domain and range of g ( x ) =
-1/4( x - 17)2 + 61?
Answer:
Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Step-by-step explanation:
Step-by-step explanation:
step 1. I assume g(x) = -(1/4)(x - 17)^2 + 61
step 2. domain is all the possible x's. all x's are permissible
step 3. domain: "all x" written as ( inf, -inf )
step 4. range is all the possible y values. g(x) is a quadratic pointing downward. the vertex (17,61) is the highest included y value
step 5. range: [61, -inf).

Braxton has money in a savings account. The equation B = 800(1 + 0.03) can be used to calculate the amount
of money in dollars, B. Braxton has in his account after t years since opening the account.
Pam also has money in a savings account. The equation P=800(1 +0.04) can be used to calculate the
amount of money in dollars, P, Pam has in her account after t years since opening the account.
Choose from the drop down menus to correctly complete each sentence.
Braxton's initial investment Choose...
• Pam's initial investment.
The interest on Braxton's account Choose...
• the interest on Pam's account.
Answer:
Braxton's initial investment is equals to (=) Pam's initial investment.
The interest on Braxton's account is less than (< ) the interest on Pam's account.
Step-by-step explanation:
Given - Braxton has money in a savings account. The equation
B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money
in dollars, B, Braxton has in his account after t years since opening
the account.
Pam also has money in a savings account. The equation
P=[tex]800(1 + 0.04)^{t}[/tex] can be used to calculate the amount of money in
dollars, P, Pam has in her account after t years since opening the
account.
To find - Braxton's initial investment ..........Pam's initial investment.
The interest on Braxton's account .....the interest on Pam's account.
Proof -
As given, Broxton equation is - [tex]800(1 + 0.03)^{t}[/tex]
Pam equation is - [tex]800(1 + 0.04)^{t}[/tex]
Now,
1.)
For initial investment , Put t = 0
⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]
P = [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]
As for t = 0
Braxton's equation , B = Pam's equation,P
⇒Braxton's Initial investment = Pam's initial investment.
2.)
For the interest,
As we don not have time for which the interest has to be check.
So , let the time period = 5 years
Therefore,
B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.1593) = 927.42[/tex]
P = [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.2166) = 973.32[/tex]
Now,
Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127
Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173
∴ we get
The interest on Braxton's account is less than the interest on Pam's account.

Question 20:- Fahein is interested in purchasing an AC too. He will give three times more points to energy efficiency and two points more to noise levels than sevices and installation. Whereas, design features don't matter to him. In this case he devises a way to compare the 5 models. Which one is the correct formula given his preferences?
Answer:
[tex]Total = 3E + 2N + S[/tex]
Step-by-step explanation:
Given
Represent
Efficiency with E; Noise Level with N
and Service and Installations with S
Required
Determine the correct formula
From the question
3 points goes to E: i.e. 3E
2 points goes to N: i.e. 2N
The above is the number of points more than service and installations.
So 1 point will be given to S i.e. S
The total or formula is:

The measure of Angle 1 is 35º and it is complementary to Angle 2. The
measure of Angle 2 is 5x. What is the value of x?
Answer:
x = 11
Step-by-step explanation:
35 + 5x = 90 {Complementary angles}
Subtract 35 from both sides
5x = 90 - 35
5x = 55 {Divide both sides by 5}
x = 55/5
x = 11
