Solve the system using elimination.
3x + 5y = 15
x+y=7
Type your answer as a coordinate pair in the textbox
below.
Step-by-step explanation:
3x + 5y = 15
x + y = 7
This can be written as ,
3x + 3y = 21
Subtracting i and iii ,
5y - 3y = 15 -21
2y = -6
y =-6/2
y = -3
So that ,
x = 21 - 3*-3 /3
x = 21 +9/3
x = 30/3
x = 10
Answer:
3x+5y=15x+y=7
Step-by-step explanation:
3x+15x+5y+y=7

During a visit to a primary care physician's office, the probability of having neither lab work nor referral to a specialist is 0.21. Of those coming to that office, the probability of having lab work is 0.41 and the probability of having a referral is 0.53. What is the probability of having both lab work and a referral?
Answer: 0,06?
Step-by-step explanation:
The probability of having both lab work and a referral is 0.94
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
It is given that the probability of having neither lab work nor referral to a specialist is 0.21.
The probability of having lab work is 0.41 and the probability of having a referral is 0.53.
The probability of having both lab work and a referral;
0.41 + 0.53
= 0.94
Therefore, The probability of having both lab work and a referral is 0.94

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A hamster weighs half a pound and costs $2 per week to feed, while a Labrador Retriever weighs 62.5 pounds and costs $10 per week to feed.
Using weight as the explanatory variable, what is the slope of a line between these two points? Answer choices are rounded to the nearest hundredth.
Answer:
$0.13 per lb
Step-by-step explanation:
The slope of a line between these two points is 0.13.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given that A hamster weighs half a pound and costs $2 per week to feed.
Labrador Retriever weighs 62.5 pounds and costs $10 per week to feed.
Let x be the weigh and y be the feed cost.
The two points of lines are (0.5, 2) and (62.5, 10)
m=10-2/62.5-0.5
m=0.13
Hence, the slope of a line between these two points is 0.13.

Answer:
$776.59
Step-by-step explanation:
For this question, you must use the formula for being compounded continuously. A=Pe^r*t. A stands for your total balance, the part you are trying to find. P stands for the initial amount. E is a constant. R is the rate of interest. And t is the number of years taken. So, to fill in the formula: P is 550, t is 15, and R would be 0.023. For R, remember not to just take the percentage, you must divide the percent of interest by 100, so 2.3 by 100 to get to 0.023. The formula should know be A= (550) e^ (0.023)(15). plug that into your calculator, and you should get $776.59.

Step-by-step explanation:
This table represents the number of inches, and, if it goes after him, month and a new pot. When graft, all the points in the table lie on the same line. What are the slope and y-intercept of the line? A) slope = 2, y-intercept = -4. B) slope = 1, y-intercept = 2. C) slope = -2, y-intercept = -4. D) slope = -1, y-intercept = 2
Answer:
r: Slope = 5/4
y-intercept = 2
Step-by-step explanation:
We have the table:
Months, m Plant height in inches, n
0 2
2 4.5
4 7
6 9.5
We want a linear relationship to represent this table.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
In this case we can select any pair of points, for example, i will choose the first two:
(0, 2) and (2, 4.5)
Then the slope is:
a = (4.5 - 2)/(2 - 0) = (2.5/2) = 1.25 = 5/4
Then our line can be written as:
y = (5/4)*x + b
To find the value of b, we can replace the values of any of the points in the equation, for example, i will use the point (0, 2) or x = 0, y = 2.
2 = (5/4)*0 + b
2 = b
Then our equation is:
y = (5/4)*x + 2.
Slope = 5/4
y-intercept = 2

Calculate the net force needed to accelerate a 200 kg piano 0.25 m/s^2
Answer:
50 N
Step-by-step explanation:
Net Force= Mass x Acceleration
F=200x0.25
F= 50 N
The net force needed to accelerate a 200 kg piano is 50 Newtons.
What is the force?A force is an effect that can alter an organization’s behavior according to physics. A mass-containing object can change its velocity, or accelerate, as a result of a force. An obvious way to define force is as a thrust or a pull. A vector quantity is called a force since it has both strength and direction.
Force is given as,
F = ma
Where m is the mass of the object, a is the acceleration of the object, and F is the force exerted on the object.
The value of mass is 200 kg and the acceleration of the piano is 0.25 m/s².
Then the force on the piano is given as,
F = 200 x 0.25
F = 50 N
The net force needed to accelerate a 200 kg piano is 50 Newtons.

The answer is 61/10
Step-by-step explanation:
