What is the y- intercept of the graph of 3x+4y=24
Answer:
6
Step-by-step explanation:
First we must get the equation in slope intercept form
y=mx+b
where m is the slope and b is the y intercept
3x+4y=24
To get this equation in slope intercept form, we have to get y by itself.
First, subtract 3x from both sides
3x-3x+4y=24-3x
4y= -3x+24
Now, divide both sides by 4
4y/4=-3x/4+24/4
y=-3/4x+6
So the y intercept is 6
The y-intercept of the graph of the equation 3x + 4y = 24 is y = 6.
What is the y-intercept of the graph?Given the equation of the graph in the question:
3x + 4y = 24
The y-intercept of a graph is simply the point where the graph crosses the y-axis, meaning that the x-coordinates must be zero.
To determine the y-intercept of the graph of the equation 3x + 4y = 24, replace x with 0 and solve for y:
3x + 4y = 24
Substitute x = 0 into the equation:
3(0) + 4y = 24
Simplifying, we get:
0 + 4y = 24
4y = 24
Divide both sides by 4, to isolate the y-variable:
y = 24/4
y = 6
Therefore, the graph intersects the y-axis at the point (0, 6).

3. Write an equation in slope-intercept form of the line that passes
through the point (4, -1) and has a slope of 2.
A. y = 2x - 7
B. y = 2x - 9
C. y = 2x + 7
D. y = 2x + 9
Answer:
B. y = 2x - 9
Step-by-step explanation:
All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.
You can tell by plugging the point into the equation and seeing if the result is true.
y = 2x - 9
-1 = 2(4) - 9
-1 = 8 - 9
-1 = -1

-15 = 2x + 1
Solve for x. Show or explain your work. Then, verify that your solution is correct.
Answer:
see below
Step-by-step explanation:
-15 = 2x + 1
Subtract 1 from each side
-15-1 = 2x + 1-1
-16 = 2x
Divide each side by 2
-16/2 = 2x/2
-8 =x
Check
-15 = 2(-8) + 1
-15 = -16+1
-15 = -15
Answer:
-8
Step-by-step explanation:
subtract 2x to move it to the left side
-2x-15=1
add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1
-2x=16
divide by -2 to get x by its self
-2x=16/2x

Suppose that the probability that a person will die in the next 20 years is
8.1393%. If this person has a life insurance policy that will pay out $50,000 to
the beneficiaries of the policy if the person dies in the next 20 years, what is
the premium of the policy? Assume that the administrative costs of the poticy
amount to $55.
A. 4824.65
B. 25,000
C. 4536.30
D. 4124.65
Answer:
Step-by-step explanation:
b is the answer
The premium of the policy is $4,124.65.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The premium of an insurance policy is calculated based on the probability of an event occurring and the amount that will be paid out if the event occurs.
To calculate the premium of the policy in this case, we can use the following formula:
Premium = (Payout + Administrative Costs) x Probability of Event
Where:
Payout = $50,000
Administrative Costs = $55
Probability of Event = 8.1393% = 0.081393 (in decimal form)
Substituting these values into the formula, we get:
Premium = ($50,000 + $55) x 0.081393
Premium = $4,124.65
Therefore,
The premium of the policy is $4,124.65.

If A and B are independent events, P(A and B) =
A. P(A)
B. P(B)
C. P(A) * P(B)
D. P(A) + P(B)
Answer:
C
Step-by-step explanation:
Since events A and B occur independently, it means that if A occurs, B May or May Not occur, vice versa. (basically, event A and B can occur on its own or together which are not dependent on the other event)
For probability of A and B to occur, and that probability of A / Probability of B occurring are not dependent on each other at any circumstance, u need to multiply the P(A) and P(B) to find out the chances of A and B occurring.

Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.Given:
The streets represented by lines V and W are parallel.
We need to determine the measure of ∠1.
As, Corresponding angles are those in the matching corners formed when a transversal line crosses two parallel lines.
Additionally, the size of the corresponding angles is consistently the same.
So, From the figure, the ∠1 and the other angle in the parallel line V with the measure of angle 155° are corresponding angles.

Based on the type of equations in the system, what is the greatest possible number of solutions? x^2+y^2=9
9x+2y=16
Answer:
B
Step-by-step explanation:
The possible number of solutions is 2.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are x² + y²=9 and 9x+2y=16
The graph of first equation is circle and the graph of second equation is a line.
We know that a line can intersect a circle at most 2 times. So, the greatest possible number of solutions is 2.
First equation can be rewritten as x² + y²=3²
It is the standard form of a circle , where (h,k) is center and r is radius.
(x-h)² +(y-k)² =r² where (h,k) is center and r is radius.
In the above equation h=0,k=0 and r=3. It is a circle with radius 3 and centered at origin.
The second equation is 9x+2y=16
It is a linear equation.

Plot these points on a coordinate plane and connect them by a straight line.
From the below graph it is clear that the line and circle intersect each other at two points. So, the given system of equation have two solutions.
Hence, the possible number of solutions is 2.
