a system of linear equations is graphed. which ordered pair is the best estimate for the solution to the system?
a) (1/3,1)
b) (1/2,0)
c) (1,1)
d) (1/3,0)
Answer:
The answer that gives the best estimate is (1,1)
Step-by-step explanation:
i) As can be seen on of the lines intercepts the y axis at (0,-1). So the y
intercept or [tex]c_{1}[/tex] = -1. Therefore the equation for this line can be written as
y = [tex]m_{1}[/tex] x + [tex]c_{1}[/tex] ⇒ y = [tex]m_{1}[/tex] x - 1 . It can also be seen from this graph that the
line passes through the point (2 , 2). Substituting these values for x and y
respectively we get 2 = 2[tex]m_{1}[/tex] - 1 ∴ [tex]m_{1}[/tex] = [tex]\frac{3}{2}[/tex]. The equation of the first line
can be written as y = [tex]\frac{3}{2}[/tex] x - 1 ⇒ 2y - 3x = -2
ii) As can be seen on the other line the intercept on the y axis is at (0,2). So
the y intercept or [tex]c_{2}[/tex] = 2. Therefore the equation for this line can be
written as y = [tex]m_{2}[/tex]x + [tex]c_{2}[/tex] ⇒ y = [tex]m_{2}[/tex] x + 2 . It can also be seen from this
graph that the line passes through the point (1 , -1). Substituting these
values for x and y respectively we get 1 = 1[tex]m_{2}[/tex] + 2 ∴ [tex]m_{2}[/tex] = -1 . The
equation of the second line can be written as y = - x + 2 or x + y = 2
iii) Solving the two equations of the two lines respectively as found in i) and
ii) we get y = 0.8. We multiply equation in ii) by 3 to get 3x + 3y = 6 and
when we add this to equation in i) we get 5y = 4 which means that y = 0.8.
If we substitute this value in ii) we get 0.8 + x = 2 , therefore x = 1.2.
iv) Therefore we get the solution of the two lines, which is the intersection
of the two lines as (1.2, 0.8). So the answer that gives the best estimate
is (1,1)

Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car results in 440 miles on 20 gallons of gas. How far could you drive on 60 gallons o gas? What is the car’s gas mileage?
Answer:
Step-by-step explanation:
20 : 440 = 60:x
Product of means = 440*60
Product of extremes = 20*x
20*x = 440*60
x = 440*60/20 = 440*3
x = 1320 miles
George finished 1/4 of a level on his computer games in 1/3 of an hour at this rate. How many hours will it take to complete on level?
Answer:
1 hour 20 minutes
Step-by-step explanation:
It takes twenty minutes to finish a quarter of one level. Which indicates that it would take one hour and twenty minutes to finish said level by simply multiplying twenty by four.
George will complete a level on his computer games in 1 1/3 of the hours.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that he finished 1/4 of a level on his computer games in 1/3 of an hour at this rate.
Let x the number of hours will it take to complete on a level
According to the given question, we can write the ratio would be as:
1/4 of a level : 1/3 of an hour = 1 level : x hour
⇒ (1/4) / (1/3) = 1/x
Apply the cross-multiplication operation,
⇒ x = (1/3) × 4
⇒ x = 4/3
⇒ x = 1 1/3
Therefore, there will be 1 1/3 of the hours it takes to complete a level.

Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units.
Q: what’s the value of t?
a) 2
b) 3
c) 6
d) 8
The value of t = 2. Option a) 2 is the correct answer.
Step-by-step explanation:
Perimeter is the sum of three sides of a triangle.
Given that, the points D and E are midpoints of the sides.
Therefore,

where x is the number of years after 1900
- 376.4x + 48,685 if x 290
Complete parts (a) (b)
a) What does this model give as the number of banks in 1970? 1990? 2010?
The number of banks in 1970 is
Answer:
1990
Step-by-step explanation:
The number of banks in 1970 is 18,137, in 1990 is 3, and in 2010 is 7,250.
(a) Since 1970 is 70 years after 1900,
use the function f(x) = 81.8x + 12,361 for the years before 1990 (when x < 90).
f(70) = 81.8 * 70 + 12,361
= 5776 + 12,361
= 18,137
The number of banks in 1970 is 18,137.
(b) Since 1990 is exactly 90 years after 1900,
use the other part of the function f(x) = 3 for the years between 1990 and 2010.
f(90) = 3
The number of banks in 1990 is 3.
(c) Since 2010 is 110 years after 1900, use the function
f(x) = -376.4x + 48,685 for the years after 290 (when x > 290).
f(110) = -376.4 * 110 + 48,685
= -41404 + 48,685
= 7250
The number of banks in 2010 is 7,250.
So, the number of banks are 18,137, 3 and 7,250.

How much greater is the area of a circle with a radius of 6.2 inches than the area of a square with a side length of 4 inches?
Answer:
7.54 times greater.
Step-by-step explanation:
The square with a side length of 4 inches has a 4×4=16 inches squared area. The area of a cirkel is calculated with the formula \pi×r^2. Using the 6.2 inch radius given, we get \pi×6.2^2=120.76 inches squared. 120.76/16=7.54 times greater.
Final answer:
Calculate the difference in area between a circle and a square given their respective dimensions.
Explanation:
To find the area of a circle with a radius of 6.2 inches:
Calculate the area using the formula A = πr², where r = 6.2 inches.Area of circle = π x (6.2)² = 38.48 square inches.To find the area of a square with a side length of 4 inches:
Calculate the area of the square using the formula A = s², where s = 4 inches.Area of square = 4 x 4 = 16 square inches.Subtract the area of the square from the area of the circle to find the difference:
Difference = 38.48 - 16 = 22.48 square inches.

Answer:
B
Step-by-step explanation:
move x to one side and numbers on another side.
9+5<3x+4x. --» 14<7x. --»/7--» x>2
Final answer:
The inequality 9 - 4x < 3x - 5 simplifies to x > 2 after collecting like terms and performing basic algebraic operations. Therefore, the correct answer is B. x > 2.
Explanation:
To solve the inequality 9 - 4x < 3x - 5, we need first to collect like terms on one side. This step involves moving all the x terms to one side of the inequality and the constant terms to the other side.
Let's do this now:
Add 4x to each side: 9 - 4x + 4x < 3x - 5 + 4x, which simplifies to 9 < 7x - 5.Next, add 5 to each side: 9 + 5 < 7x - 5 + 5, which simplifies to 14 < 7x.Finally, divide each side by 7: 14/7 < 7x/7, which simplifies to 2 < x.The answer is x > 2, which corresponds to option B.

Step-by-step explanation:
Given:
Bernie, Eddy and Gery share £450.
Bernie gets twice as much as Eddy.
Eddy gets three times as much as Gery.
So,
Let Gery gets 'x' share of the amount.
Then,
Eddy's share will be '[tex]3x[/tex]'
and
Bernie's share will be [tex]2\times 3x=6x[/tex]
According to the question.

The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4

x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
the area of the square ABCD = 7
on the other hand, the area of the square ABCD = (2+x)² = x² + 4x + 4
then x² + 4x + 4 = 7
then x² + 4x + 4 = 4 + 3

Marys watch keeps perfect time and Bills watch loses 4 minutes a day.
Both watches are set at midnight on January 1. How many times a year will they match?
Bill's and Mary's watches will match once a year on a non-leap year and twice a year on a leap year since Bill's watch loses 4 minutes per day. After 360 days, Bill's watch will be exactly 24 hours behind Mary's.
You asked how many times a year Mary's watch (which keeps perfect time) and Bill's watch (which loses 4 minutes a day) would match if they were both set at midnight on January 1. This is a mathematical problem involving the concept of elapsed time.
Since Bill's watch loses 4 minutes per day, after 1 day, there will be a 4-minute difference between the two watches. As this pattern continues, we calculate how many days it will take for Bill's watch to lose an entire 24-hour cycle (1440 minutes) since 1440 minutes divided by 4 minutes/day equals 360 days. Therefore, Bill's watch would match Mary's watch exactly one more time, 361 days after both watches were set, which would be on the next New Year's Eve, just before both watches hit midnight.
However, this scenario would only occur in a non-leap year. During a leap year, Bill's watch would be 4 minutes slow on December 30th instead of on December 31st, so Bill's watch would match Mary's watch two times in a leap year, once on January 1st and again on December 30th. In conclusion, Bill's and Mary's watches match once a year during a non-leap year and twice during a leap year.
