The line passes through points [tex](2,0)\,,\,(0,2)[/tex]
Let [tex](x_1,y_1)=(2,0)\,,\,(x_2,y_2)=(0,2)[/tex]
Equation of a line passing through points [tex](x_1,y_1)\,,\,(x_2,y_2)[/tex] is given by [tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\frac{2-0}{0-2}(x-2)\\y=\frac{2}{-2}(x-2)\\y=-1(x-2)\\y=-x+2[/tex]
So,
[tex]f(x)=y=-x+2[/tex]
Put [tex]x=-2[/tex]
[tex]f(-2)=-(-2)+2=2+2=4[/tex]

In a survey of 3,400 people who owned a certain type of car, 1,700 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answers
Answer:
50%
Step-by-step explanation:
Calculation for What percent of the people surveyed were satisfied with the car
Using this formula
Percentage of people satisfied=Owners of car/Numbers of people to buy the same car again
Let plug in the formula
Percentage of people satisfied=1,700/3,400 people*100
Percentage of people satisfied=0.5*100
Percentage of people satisfied=50%
Therefore the percentage of the people surveyed who were satisfied with the car is 50%

Answers
Answer:
16. Adults = $12
17. 750 ml
18. $9
19. 96 students
20. 5/6x
Step-by-step explanation:
16.
A child pays = $9
Bus fee = 1/3 of $9
= 1/3× 9
= $3
Admission fee for a child= amount paid - bus fee
= $9 - $3
= $6
What was the admission fee for adults, if children get in for haprice
Children = 1/2 of adults
$6 = 1/2 × adults
Adults = 6÷ 1/2
= $12
Adults = $12
17.
Leaking rate = 10 ml per minutes
One and quarter of an hour
1 hour = 60 minutes
Quarter of an hour = 15 minutes
Total time = 75 minutes
Air lost in 75 minutes = 10 ml × 75
= 750 ml
18. 4 glasses for $3
1 dozen of glasses = 12

x = 36 / 4
= 9
x = $9
19.
Total students = x
1/2x = soccer
Rugby = 1/2 of 1/2x
= 1/2 * 1/2x
= 1/4x
24 = 1/4x
x = 24÷1/4
= 24 × 4/1
x = 96 students
20.
Total petrol = x
Petrol in the tank = 1/2x
Petrol used = 1/3 of 1/2x
= 1/3 × 1/2x
= 1/6x
Petrol remaining after the trip = x - 1/6x
= 6x-x/6
= 5/6x

Answers
Given:
Gracie is sharing 75 marshminnows among 4 of her friends.
Each of her friends gets the same number of marshminnows, and she gives them as many marshminnows as possible.
To find:
The remaining number of marshminnows she has.
Solution:
We have,
Total number of marshminnows = 75
Number of friends = 4
Divide 75 by 4.
[tex]4|\overline{75}|{18}\\ -4\\\text{\quad }\overline {35} \\ -32\\\text{\quad }\overline {\ 3\qaud }[/tex]
Here, quotient is 18 and remainder is 3. It means, each friend can be get maximum 18 marshminnows and the number of remaining marshminnows is 3.
Therefore, the correct option is B.

Q.10...In a cookie mix, we find chocolate chip cookies, spice cookies, and ginger cookies in a ratio of 4 : 3 : 3. If a bag of the mix contains 33 ginger cookies, how many chocolate chip cookies are there?
Answers
Answer:
13.2
Step-by-step explanation:
Let 4x represent the chocolate chip cookies
Let 3x represent the spice cookies
Let 3x represent ginger cookies
4x + 3x + 3x = 33
10x = 33
x = 33/10
x = 3.3
Since 4x represents chocolate chip cookies
4 × 3.3
= 13.2
Hence there are 13.2 chocolate chip cookies
The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.
Answers
Answer:

original price = 100%
selling price = 100% - 7% = 93% = £500
just do the proportion or ratio
[tex] \frac{100\%}{93\%} = \frac{original \: price}{500} [/tex]
OP = 500 x 100% / 93%
OP = £ 537.634

Maximum value of z = 21
Minimum value of z = -9
Step-by-step explanation:
We have to maximize/minimize the given equation for the given constraints as,
x ≥ -1
y ≤ -2x + 3
y ≥ -1
By using the graphing tool,
Corner points for the feasible region are,
A(-1, 5), B(-1, -1) and C(2, -1)
For A(-1, 5),
z = 4x + 5y = 4(-1) + 5(5)
= -4 + 25
= 21
For B(-1, -1),
z = 4(-1) + 5(-1)
= -4 - 5
= -9
For C(2, -1),
z = 4(2) + 5(-1)
= 8 - 5
= 3
Maximum value of z = 21
Minimum value of z = -9
