y=3x-11
y-3x=-13
Solving using systems of equations
Answer: There are no possible solutions because
If you were to plot these two equations on the graph you would notice they are parallel because both have the same slope (3x) but still have different intercepts. This means there are no possible solutions as in order to have a solution for x and y they need to intercept and the point of interception is the solution for x and y but that cannot happen in a system of equations that result in parallel lines ( they’ll never intercept)
Answer:
Ø
Step-by-step explanation:
These equations are parallel, meaning they have SIMILAR rate of changes [slopes]. To prove it, convert the second equation from Standard Form to Slope-Intercept Form:
[tex]\displaystyle y - 3x = -13 \hookrightarrow y = 3x - 13 \\ \\ \left \{ {{y = 3x - 13} \atop {y = 3x - 11}} \right.[/tex]
As you can see, both equations have a rate of change of 3, meaning we CANNOT obtain a solution here, therefore we have no solution.

Kellie wants to cover part of the lawn with pavers to make a nice place to put a table and some chairs. This space will be a rectangle with an area of 108 square feet, and the rectangle will be 3 feet longer than wide. What will the dimensions of this rectangle be? In other words, what will the length and width be?
For the record, the formula for the area of a rectangle is A = LW.
8a) Clearly write out the equation you would use to answer the question.
8b) Answer the question. What will the dimensions be? Please write your answer as a complete sentence with appropriate units.
8a)
x = width
x+3 = length, since its 3 ft longer than the width
A = length*width
A = LW
A = (x+3)*x
A = x^2+3x
Set this equal to 108 since this is the area of the rectangle.
Answer: x^2 + 3x = 108=========================================================
8b)
x^2+3x = 108
x^2+3x-108 = 0
Use the quadratic formula with a = 1, b = 3, c = -108
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(3)\pm\sqrt{(3)^2-4(1)(-108)}}{2(1)}\\\\x = \frac{-3\pm\sqrt{441}}{2}\\\\x = \frac{-3\pm21}{2}\\\\x = \frac{-3+21}{2} \ \text{ or } \ x = \frac{-3-21}{2}\\\\x = \frac{18}{2} \ \text{ or } \ x = \frac{-24}{2}\\\\x = 9 \ \text{ or } \ x = -12\\\\[/tex]
Ignore the negative solution because we cannot have a negative width.
x = 9 is the width
x+3 = 9+3 = 12 is the length being 3 longer.
The rectangle is 12 ft by 9 ft to get an area of 12*9 = 108 sq ft, which confirms the answer.
Answer: 12 feet by 9 feetA number divided by 7 is –35.

The equation of the given graph is g(x) = (1/4)x². The correct answer is an option (A).
What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function.
The graph of g(x) = (1/4)x² is a parabola that opens upwards and is wider than the graph of f(x) = x².
The vertex of the parabola is at the origin (0, 0), and the shape of the curve is determined by the coefficient of x², which is 1/4 in this case.
The graph of f(x) = x² is also a parabola that opens upwards, but it is narrower than the graph of g(x) = (1/4)x².
The vertex of the parabola is also at the origin (0, 0), but the curve is steeper because the coefficient of x² is 1, which is greater than 1/4.
Thus, the correct answer is an option (A).

Juan has a mass of 50 kg. If he is running at a velocity of 2 m/s, how much kinetic energy does he have?
Answer:
100 J
Step-by-step explanation:
Kinetic energy is jointly proportional to mass and the square of the velocity.
KE = 1/2mv²
KE = 1/2(50 kg)(2 m/s)² = 100 J
Juan has a kinetic energy of 100 joules.

Show the steps of the synthetic division!
Answer:

Step-by-step explanation:
The value of f(3) is told by the remainder theorem to be the remainder from division of f(x) by (x -3). That division is shown in the attachment. The remainder is 1, so ...
f(3) = 1

When the polynomial is written in Horner Form:

the coefficient of x at each point in the evaluation is the same as the number on the bottom row of the synthetic division. The result of the evaluation is the same as the remainder from the division.

A study found that 9% of dog owners brush the dogs teeth. Of 578 dog owners, about how many would be expected to brush their dog’s teeth? explain.
Answer:
52
Step-by-step explanation:
Step 1: Our output value is 578.
Step 2: We represent the unknown value with [tex]x[/tex].
Step 3: From step 1 above, [tex]578=100%[/tex]%
Step 4: Similarly, x=9%
Step 5: This results in a pair of simple equations:
578 = 100% (1)
x = 9% (2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
578/x = 100% /9%
Step 7: Again, the reciprocal of both sides gives
x/578 = 9 /100
⇒ x = 52.02
Therefore, 9% 578 is 52.02
Round:
Answer: About 52 dog owners are expected to brush their dogs teeth.
