Which of the following points lie in the solution set to the following system of inequalities?
y > −3x + 3
y > x + 2
A.(2, −5)
B.(−2, 5)
C.(2, 5)
D.(−2, −5)
Answer:
C
Step-by-step explanation:
It’s convenient that there are only two x values you need to check, -2 and 2. Just insert it to see what y is appropriate.
x = -2: y > 6 + 3 = 9 (and y > -2 + 2 = 0 which is redundant here)
x = 2: y > 2 + 2 = 4 (and y > -6 + 3 = -3 which is redundant here)
So, neither B nor D is in the solution set with 5 < 9 and -5 < 9.
A isn’t in the solution set either with -5 < 4.
C is in the solution set with 5 > 4.
Answer:
c

A group of 53 tourists visit a museum. Museum volunteers lead tours for groups of no more than 8 tourists. Draw a model to show the least number of groups that can be formed for these 53 tourists. Use circles to show the groups and choose a symbol to show each person.
Answer:
Total number of group formed = 7
Step-by-step explanation:
As given,
1 group has 8 people
Total people = 53
Let
Total number of group made = x
As 1 group = 8 tourist
⇒x group = 8x tourist
As Total tourist = 53
⇒8x = 53
⇒x = [tex]\frac{53}{8}[/tex] = 6.6
This means,
There are 6 full group of 8 people in each group = 48 tourist
and 1 group of 53-48 = 5 people.
So,
Total number of group formed = 7
In the diagram , Δ represent each person.

The fabric cost 7cents per square inch. She will only pay for the fabric used to cover the box, even if there is waste or extra. How much money did shyla spend on fabric? Is the box is 7 by 11by 8 inchs
Answer:
Shyla will pay about 63 cents to cover the box
Step-by-step explanation:
Length of the box ( l ) = 7 inches
Width of the box (b) = 11 inches
Height of the box (h) = 8 inches
We can solve this equation by following two simple steps.
1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.
We can get this by the following formula:
SA=2( length X width) +2( length X height )+2(height X width)
SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches
2. The second step is to divide the total surface area by the price of the fabric per square inch.
This will be 442 square inches divided by 7 cents per square inch = 63.14 cents
Shyla will pay about 63 cents to cover the box
find the value of b
8 b+3 6

Find the unknown side length
A, B, C, D are points on a line, with D the midpoint of segment BC. The
lengths of segment AB is 10; segment AC is 2; and segment BC is 12. What
is the length of segment AD?
Answer:
Also BC = 12
B......6......D......6......C
Now, AC = 2.
A can be either left of C or right of C
If A is left of C , AB = 12-2 = 10 (Correct)
If A is right of C AB = 12 +2 = 14 (Incorrect)
So the points placing is as below
B......6......D....4....A..2..C
Length of segment AD = 4
Tasha lists all the multiple of 3 from 3 to99. Tony lists all the multiples of 5 from 5 to100. What is the first number that is on both lists? The second.
Answer:
Multiples of 3 = 3, 9Multiples of 5 = 5, 10Step-by-step explanation:
In a list of 3 to 99, the first multiple of 3 will be none other than 3 itself because when multiplied by 1, you get three.
The second number will be: 3 * 2 = 6
In a list from 5 to 100, the first multiple will be 5 with 5 being a multiple of itself when multiplied by 1.
Second number = 5 * 2 = 10

A, B and D are points on the circumference of a circle, centre O.
BOD is a diameter of the circle.
BC and AC are tangents to the circle.
Angle OCB =34.
Work out the size of angle DOA.
Answer:
Step-by-step explanation:
A tangent makes a 90° angle to the circle.
∠BOC = 180°-90°-34° = 56°
△AOC is congruent to △BOC, so ∠AOC = 56°
∠DOA = 180°-56°-56° = 68°
The size of the angle DOA is 68°
What is the tangent of the circle?"It is the line which intersects the circle exactly at one point."
For given example,
BC and AC are tangents to the circle.
∠OCB = 34°
As, OC is the angle bisector for ∠ACB
⇒ ∠OCB = ∠OCA
⇒ ∠OCA = 34°
⇒ ∠ACB = ∠OCB + ∠OCA
⇒ ∠ACB = 34° + 34°
⇒ ∠ACB = 68°
We know, the tangent to a circle is perpendicular to the radius of the circle.
⇒ CB ⊥ OB
⇒ ∠OBC = 90°
and CA ⊥ OA
⇒ ∠OAC = 90°
We know, the sum of all angles of quadrilateral is 360°.
For quadrilateral ACBO,
⇒ ∠OAC + ∠ACB + ∠OBC + ∠BOA = 360°
⇒ 90° + 68° + 90° + ∠BOA = 360°
⇒ ∠BOA = 112°
We know, the angle subtended by semicircle is 180°.
⇒ ∠AOB + ∠DOA = 180°
⇒ 112° + ∠DOA = 180°
⇒ ∠DOA = 68°
Therefore, the size of the angle DOA is 68°

Answer:
X = 2, 4, 6, 7, 9
Y = 29, 33, 37, 39, 43
Step-by-step explanation:
Given a best fit line of :
y = 2x + 25
Take points X as :
X = 2, 4, 6, 7, 9
X = 2
y = 2(2) + 25 = 4 + 25 = 29
X = 4
y = 2(4) + 25 = 8 + 25 = 33
X = 6

A point R (-2,5) is mapped to point R',as described by a translation of 6 units to the rights and 7 units down.Mark R' on the coordinate plane.
Answer:
(4, -2)
Step-by-step explanation:
Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;
6 units to the rights is towards the positive x axis
7 units down is towards the negative y axis
R' = (-2+6, 5-7)
R' = (4, -2)
Hence the coordinate point of R' on the plane is (4, -2)

35 of the apartments have a balcony and 55 of them don't. An apartment is randomly selected as part of a survey. What is the probability it has a balcony?
Answer:
39%
Step-by-step explanation:
It is given that 35 apartments have balconies in them.
While 55 apartments do not have balconies in them.
Total number of balconies is the sum of the apartments. i.e. 35 + 55
= 90 apartments
Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.
i.e.
[tex]$=\frac{35}{90}$[/tex]
= 0.38888888
Multiplying by 100, we get
= 0.388888 x 100
= 38.8888 %
= 39 %
The length of a rectangle is six times its width.
If the perimeter of the rectangle is 84 ft, find its area.
The area of the rectangle is 216 square feet
How to determine the area?Let x represents the length and y represents the width.
So, we have:
x = 6y
So, the perimeter is:
P = 2(x + y)
The perimeter is given as:
P = 84
So, we have:
2(x + y) = 84
Divide by 2
x + y = 42
Substitute x = 6y in x + y = 42
6y + y = 42
Evaluate the sum
7y = 42
Divide by 7
y = 6
Substitute y = 6 in x = 6y
x = 6 * 6
x = 36
The area is calculated as:
Area = xy
So, we have:
Area = 36 * 6
Evaluate
Area = 216
Hence, the area of the rectangle is 216 square feet
