Answer:
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
Step-by-step explanation:
Each figure consists of two small squares and a square that has a side length of 1 more than the figure number. That is, ...
f(x) = (x +1)^2 +2
You can count the squares in figures 1-3. Figure 4 will be 2 more squares than 5^2 = 25, so will be 27 squares.
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)

Scarlett is playing a video game. She spends 900 minerals to create 18 workers. Each worker costs the same number of minerals.
Answers
So you would do 900÷18 to get the amount each worker is worth, which would be 50 minerals.
Answer: m=50w
Step-by-step explanation:
When you divide 900 by 18, you get 50.
Since we are trying to find the amount of minerals per worker, m is the first variable. w is the second because that is the number of workers you can get with the minerals Scarlett has.

Chelsea takes the bus to school, but she walks home. The bus travels to the school at an average speed of 45 miles per hour. While going home from school, Chelsea walks at a speed of 2.5 miles per hour.
In total, she takes 1 hour to travel to school and back. If t is the time it takes to go to school by bus, the equation that will help find the time it takes Chelsea to get to school on the bus is ANSWER1
. The equation will have ANSWER2
PLS ANSWER ANSWER 1 AND 2
Answers
Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.
Step-by-step explanation:
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)

In the diagram shown, M, N and P are collinear and QM=QN as shown. If mMQN = 48" and
mNQP = 33. Justify why QNP must be isosceles.
Answers
Answer/Step-by-step explanation:
Let's find the measure of the angles of ∆QNP.
∆QMN is am isosceles ∆, because it has two equal sides. Therefore, its base angles would be the same. Thus:
m<MNQ = ½(180 - 48) (one of the base angles of ∆QMN)
m<MNQ = ½(132) = 66°
Next, find m<QNP
m<QNP = 180° - m<MNQ (linear pair angles)
m<QNP = 180° - 66° (Substitution)
m<QNP = 114°
Next, find m<P
m<P = 180 - (m<QNP + m<PQN) (sum of ∆)
m<P = 180 - (114 + 33)
m<P = 180 - 147
m<P = 33°
Thus, in ∆QNP, there are two equal angles, namely, <P and <PQN.
An isosceles ∆ had two equal base angles. Therefore, ∆QNP must be an isosceles ∆.
An isosceles triangle is that the triangle must have two sides of equal length.
Triangle QNP is isosceles triangle because, QN = PN
In triangle QMN,
Since, QM = QN
So, ∠QMN = ∠QNM
By property of triangle:
∠MQN + ∠QNM + ∠QMN = 180
48 + 2 ∠QNM = 180
∠QNM = [tex]\frac{180-48}{2}[/tex] = 66 degree
So, ∠QMN = ∠QNM = 66 degree
from figure,
∠QNM + ∠QNP = 180
∠QNP = 180 - 66 = 114 degree.
In triangle QNP,
∠QNP + ∠PQN + ∠QPN = 180
∠QPN = 180 - 33 - 114 = 33 degree
Since, ∠QNP = ∠QPN = 33 degree
Therefore, triangle QNP is isosceles triangle.

Step-by-step explanation:
The slope of a line is usually represented by the letter m. (x1, y1) represents the first point whereas (x2, y2) represents the second point. It is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope.
In the following expression, both A and B are variables that can take positive values.
2\sqrt(A)-(B)/(5)
Which of these actions will cause the expression's value to increase?
Choose 2 answers:
(Choice A)
Keeping A constant and increasing B
(Choice B)
B
Keeping A constant and decreasing B
(Choice C)
C
Increasing A and keeping B constant
(Choice D)
D
Decreasing A and keeping B constant
Answers
Answer:
(Choice B) Keeping A constant and decreasing B
(Choice C) Increasing A and keeping B constant
Step-by-step explanation:
Let us analyze these two options.
2√a - b /5
(Choice B) Keeping A constant and decreasing B
Let a = 100 and b= 30
2√100 - 30/5
= 2(10) - 6
= 20 -6= 14
But if A is kept constant and B is decreased to 20
2√100 - 20/5
= 2(10) - 4
= 20 -4= 16
We see the expression value has increased from 14 to 16.
Similarly analyzing Option C
(Choice C) Increasing A and keeping B constant
Let a = 100 and b= 30
2√100 - 30/5
= 2(10) - 6
= 20 -6= 14
Now increasing A to 121 and keeping B constant would give
Let a = 100 and b= 30
2√121 - 30/5
= 2(11) - 6
= 22 -6= 16
This also increases the expression's value
But the other two choice A and D do not give the same result.
Let a = 100 and b= 30
2√100 - 30/5
= 2(10) - 6
= 20 -6= 14
(Choice A)
Keeping A constant and increasing B
2√100 - 40/5
= 2(10) - 8
= 20 -8= 12
This decreases the value .
Also
(Choice D)
Decreasing A and keeping B constant
2√81 - 40/5
= 2(9) - 8
= 18 -8= 10
This also decreases value
The correct choices are B and C

the acutal solution is B and D

If a is 63% of x and c is
8
the closest equivalent of the ratio of a to c?
ã of x, which of the following is
O
С C
E
Answers
Answer:
The closest equivalent of the ratio of a to c will be:
a/c=1.680
Step-by-step explanation:
As 'a' is 63% of x
so
[tex]a=0.63x[/tex]
As 'c' is 3/8 of x
so
c=3/8
Thus, the closest equivalent of the ratio of a to c will be:
a/c = (0.63x)/(3/8x)
= 1.680
Therefore, the closest equivalent of the ratio of a to c will be:
a/c=1.680
