Solve the system of linear equations using elimination.
−7x + 3y = −6
−3x + 3y = 6
A) (3, 5)
B) (3, −5)
C) (−3, 5)
D) (−3, −5)
Answer:
Option A) x = 3 and y = 5
Step-by-step explanation:
−7x + 3y = −6_____ first equation
−3x + 3y = 6_____ second equation
Since both equations have "y" that share the same coefficients (that is 3),we can solve this equation.
---First step is to subtract the equation 2 from 1
−7x + 3y = −6
−3x + 3y = 6
From the above equation, we have
-4x = -12
Divide both sides by -4
X = 3
--- Substitute x = 3 in equation 1
−7x + 3y = −6
-7(3) + 3y = -6
-21 + 3y = -6
3y = 21 - 6
3y = 15
Y = 5
X = 3 and y = 5( option a)

A. $1,741.02
B. $1,713.82
c. $713.82
D. $741.02
Please help I’m giving a lot of points I need this now
Answer:
the answer is b
Step-by-step explanation:
Final answer:
Ricky will have earned C. $713.82 on his $1000 investment at 8% interest compounded quarterly after 7 years, totaling $1,713.82 in the account.
Explanation:
Ricky invested $1000 in an account at 8% interest compounded quarterly. To calculate the future value of his investment after 7 years, we use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.
Given:
P = $1,000
r = 0.08 (8% written as a decimal)
n = 4 (compounded quarterly)
t = 7 (7 years)
Now we plug these values into the formula.
A = 1000(1 + 0.08/4)^(4*7)
A = 1000(1 + 0.02)^(28)
A = 1000(1.02)^28
A = $1,713.82
The correct answer is B. $1,713.82.
John runs 5 miles in 3/4 of an hour.
At the same pace, how many hours will
it take him to run only 1 mile?
John's speed is 6.67 miles per hour. Therefore, it would take him approximately 0.15 hours or 9 minutes to run 1 mile at the same pace.
Explanation:The subject of this problem is rate. We can calculate John's speed by dividing the distance he covers by the time it takes. In this case, John ran 5 miles in 3/4 of an hour. So, his speed is 5 miles divided by 3/4 hour, which equates to 6.67 miles per hour. This means he runs 6.67 miles in 1 hour.
Given that speed is constant, if John wants to run only 1 mile, we simply divide this distance by his speed. So, 1 mile divided by 6.67 miles per hour gives 0.15 hours, or approximately 9 minutes. So, it would take John about 0.15 hours or 9 minutes to run 1 mile at the same pace.

The diameter of a cylindrical construction pipe is 4 ft. If the pipe is 16 ft long, what is its volume?
Use the value 3.14 for , and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer: 201 square feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder: π x radius² x height (in our case the length of the pipe)
Since:
Diameter = radius x 2
In our case D =4
4 = 2radius
Radius= 4/2 = 2 ft
Now that we have the radius, we can use the volume formula replacing with the values given:
V = 3.14x 2² x 16 = 3.14 x 4 x16 =200.96 = 201 square feet
Two rectangular prisms have the same volume. The area of the base of the blue prism
is 4 1/8 square units. The area of the base of the red prism is one-half that of the blue
prism. Which statement is true?
CLEAR
CHECK
A.The height of the red prism is four times the height of the
blue prism.
B.The height of the red prism is two times the height of the
blue prism.
C.The height of the red prism is one-half the height of the
blue prism.
D.The height of the red prism is the same as the height of
the blue prism.
The height of the red prism must be twice the height of the blue prism.
Volume of a prism can be calculated as the area of the base multiplied by the height. Since the height of the blue prism is twice that of the red prism, the height of the red prism must be twice as much as that of the blue prism to make the volumes equal.

Answer:
The radius is 14 with a circumference of 28
The radius of the circle with circumference 28π is given by r = 14 inches
What is a Circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the radius of the circle be represented as r
Now , the equation will be
The circumference of the circle C = 28π inches
And , circumference of circle = 2πr
On simplifying , we get
2πr = 28π
Divide by π on both sides , we get
2r = 28
Divide by 2 on both sides , we get
r = 14 inches
Hence , the radius of the circle is 14 inches

Answer:
Option B.
Step-by-step explanation:
The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).
We need to find the coordinates of triangle when it is translated two units left.
So, the rule of translation is
[tex](x,y)\rightarrow (x-2,y)[/tex]
Using this rule, we get
[tex]A(-1,-1)\rightarrow A'(-1-2,-1)=A'(-3,-1)[/tex]
[tex]B(-1,-5)\rightarrow B'(-1-2,-5)=B'(-3,-5)[/tex]
[tex]C(0.5,-5)\rightarrow C'(0.5-2,-5)=C'(-1.5,-5)[/tex]
The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).
Therefore, the correct option is B.

Marcus has a bag that contains 5 identically shaped boxes. 3 of the boxes are blue and 2 are green. 2 of the blue boxes have a prize , and 1 of the green boxes has a prize 1 of the green boxes has a prize. Marcus randomly selects a box from the bag. Let A be the event that he selects a blue box and B be the event that the box contains a prize. Which of the following statements are true?
A. P(A|B) = P(A)
B. P(B|A) = P(B)
C. Events A and B are independent events
D. The outcomes of events A and B are dependent on each other.
Answer:
D. The outcomes of events A and B are dependent on each other
Step-by-step explanation:
The correct probabilities for the stated events are P(A|B) = 2/3, P(B|A) = 2/3, meaning both statements A and B are false. Since these probabilities are not equal to P(A) and P(B) respectively, this shows the events A and B are not independent, making statement C false and D true.
Explanation:To solve the problem, we first need to define the events. Event A is that a box selected is blue, and Event B is that the selected box contains a prize. We're asked to verify certain probabilities related to these events.
First, let's find the total probability of each event. The probability of selecting a blue box (Event A) is 3/5 because there are 3 blue boxes out of 5 total. The probability of selecting a box with a prize (Event B) is 3/5, as 3 of the 5 boxes contain a prize.
The probability of A given B, P(A|B), is the probability that a selected box is blue, given that it contains a prize. We know there are 3 boxes with prizes, and of those, 2 are blue. So, P(A|B) = 2/3. This is not equal to P(A) = 3/5, so Statement A is false.
The probability of B given A, P(B|A), is the probability a selected box contains a prize, given that it is blue. We know there are 3 blue boxes and 2 of them have prizes. So, P(B|A) = 2/3. This is not equal to P(B) = 3/5, so statement B is false as well.
This means Events A and B influence each other and are, therefore, not independent. This makes Statement C false and Statement D true.

What is the equation of the line?
Answer:
y = 1/4x - 3.
Step-by-step explanation:
We see that the line passes through the points (4, -2) and (0, -3) so the slope is (-3 - (-2) / (0-4)
= -1 / -4
= 1/4 = the slope of the line.
The slope-intercept form of a straight line is y = mx + b where m = slope and b = y-intercept. Here the y-intercept is at (0, -3) so b = -3.
So the equation of the line is y = 1/4x - 3.

ANSWER IS A
Answer:
A. I only
The y-axis should be labeled
Step-by-step explanation:
Proper labelling of the axis would help graph less misleading. When plotting graph, both x and y axis must be properly scaled by representing each unit with a reasonable measurement e.g taking 2cm as 1unit, 5cm as 1unit etc.
Note that rescaling the axis will only make the graph look ambiguous and confusing, therefore we must desist from scale resizing.
A graph can be misleading is if the y axis is not labeled or the correct scale are not used for either of the y axis or x axis.

ellie buys a mobile phone in spain €352.50 her brother jack buys an identical phone in japan for ¥39856 work out how much it is in £
Answer:
a) The best deal was in Japan
b) The difference is £38
Step-by-step explanation:
First, find out the cost in pounds for both of the purchases.
Japan:
39856 / 188 = 212.
the Japanese phone cost £212.
Spain:
352.50 / 1.41 = 250.
the Spanish phone cost £250.
Then, subtract the costs to find the difference:
250 - 212 = 38
The Identical phone in Japan is €28163.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Price of the phone in Spain = €352.50
Price of the phone in Japan = ¥39856
Now,
€1 = ¥141.52
Multiply 39856/141.52 on both sides.
39856/141.52 x 1€ = 39856/141.52 x ¥141.52
€28163 = ¥141.52
Thus,
The cost of a phone in Japan is €28163.
