Answer: Hello there!
we want to find the equation that passes through the point (6, -8) (where this notation stands for (x,y)) with a slope of 0.
a linear equation has the form y = ax+ b
where a is the slope and b is the intercept.
if a = 0, our equation has the form y = b (has no dependence of x)
so we have a constant equation that passes through the point (6, -8) , this means x = 6 and y = -8, but we know that y is constant:
then y = -8 = b
so our equation is y(x) = -8
WNCI is having a promotion in which every 42nd caller receives a free concert ticket to JAY-Z and every 72nd caller receives a backstage access pass. Which caller will be the first one to win both?
Answer:
504th caller
Step-by-step explanation:
To determine who would win both the free concert ticket AND the backstage access pass, we need to find the first number that is divisible by both 42 and 72 at the same time.
That's called the Least Common Multiple (LCM), and it can be found with this formula:
[tex]lcm(a,b) = (\frac{|a * b|}{gcd(a,b)} )[/tex]
Where gcd is the Greatest Common Divisor, meaning what's the greatest number that divides both numbers without any leftover.
In the case of 42 and 72, the GCD is 6.
So, let's take the formula again, punching in the numbers this time and solving it.
[tex]lcm(42,72) = (\frac{|42 * 72|}{6} ) = \frac{3024}{6} = 504[/tex]
And 504 does divide both 42 (result is 12) and 72 (result is 7).
Write the equation for 5x + 2y = 3 in slope-intercept form.
y = 5/2 x - 3/5
y = -5/2x + 3/2
y = -2/5x +3/5
the answer is :
y = -5/2x + 3/2
Answer:
Choice b is correct.y = -5/2x+3/2 is the slope intercept form of given equation.
Step-by-step explanation:
We have given the equation:
5x + 2y = 3
We have to write the equation in slope intercept form.
The general slope intercept form of equation is :
y = mx+c
Where m = slope and c is the y-intercept.
We have given the expression:
5x + 2y = 3
2y = 3-5x
y = (3-5x)/2
y = 3/2-5/2x
y = -5/2x+3/2
y = -5/2x+3/2 is the slope intercept form of given equation.
Where m = -5/2 and y-intercept = 3/2
Find the diameter of a circle with an area of 380.13m^2
Answer:
22
Step-by-step explanation:
Divide the area (in square units) by Pi (approximately 3.14159).
Example: 380.13/3.14 = 121.06
Then square the answer.
121.06 squared = 11.0
That answer is the radius, double that to get the diameter.
11.0 * 2 = 22
Final answer:
To calculate the diameter of a circle with an area of 380.13 m², solve for the radius using the formula r = √(A/π) and then double that value to find the diameter, resulting in a diameter of approximately 22.00 meters.
Explanation:
To find the diameter of a circle with a given area, we start with the formula for the area of a circle, which is A = πr², where A is the area, π (Pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. Given the area A = 380.13 m², we can solve for the radius r by rearranging the area formula to r = √(A/π) and then calculating the diameter D by doubling the radius (D = 2r).
Step 1: Calculate the radius.
r = √(A/π) = √(380.13 m² / 3.14159) ≈ 11.00m
Step 2: Calculate the diameter.
D = 2r = 2 × 11.00m = 22.00m

Which option below best describes why the domain of g(x) = 5–x is all real numbers but the range of g is not all real numbers? The domain of g is all real numbers because every real number . However, the range of g is not all real numbers because the
Answer:
The function is
g(x) = 5^(-x)
This question can be easily solved by using a graphing calculator
and plotting the graph of g(x)
In the image below, we can see that for each value of x , there is a corresponding value for g(x)
This means that the function does not have any discontinuities. Therefore,
The domain of g(x) is all real numbers (x ∈ R)
The range is related to the values that can be achieved by g(x),
Since it is a positive exponential function, all values will be g(x)>0
And the range would be (0,∞)
The domain of g(x) = 5-x is all real numbers because any real number can be an input, but the range is not all real numbers since the output is limited to values equal to or less than 5.
The function g(x) = 5-x has a domain of all real numbers because you can plug in any real number for x and it will result in a valid output. In contrast, the range of g is not all real numbers because the function g(x) can only produce certain values based on the operations involved. For instance, if x is a real number, the expression 5-x will always result in values less than or equal to 5, since you are subtracting a real number from 5. Thus, the output will never be greater than 5, so the range is all real numbers less than or equal to 5.

The courtyard behind Jennie’s house is shaped like a trapezoid the bases measures 8 meters and 11 meters the height of the trapezoid is 12 meters what is the area of the courtyard
Answer:
A = 114 m²
Step-by-step explanation:
The formula for area of a trapezoid is
A = (1/2)(B + b)h where B is the bottom base, b is the top base, and h is the height.
We are given B = 11, b = 8, and h = 12, plug those values in and simplify
A = (1/2)(11 + 8)(12)
A = (1/2)(19)(12)
A = (19)(6) (half of 12 is 6)
A = 114 m²

What is the term for a transformation that changes the size of a figure? rotation dilation reflection translation
The term that changes the size of a figure is called Dilation
Step-by-step explanation:A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A description of a dilation includes the scale factor and the center of the dilation. A dilation stretches or shrinks the original figure. Remember that to dilate something in the coordinate plane, multiply each coordinate by the scale factor
The term for a transformation that changes the size of a figure is dilation. Dilation involves stretching or shrinking a figure while maintaining its shape, using a scale factor greater than 1 for enlargement or between 0 and 1 for reduction.
The term for a transformation that changes the size of a figure is dilation.
Dilation is a geometric transformation that alters the size of a figure while keeping its shape intact. It involves stretching or shrinking the figure by a scale factor, which can either be greater than 1 (resulting in an enlargement) or between 0 and 1 (resulting in a reduction). In a dilation, all points of the original figure move away from or toward a fixed center called the "center of dilation," and their distances from the center are multiplied by the scale factor.
In contrast, other transformations have different effects:
Rotation involves turning a figure about a fixed point.
Reflection flips a figure over a line, creating a mirror image.
Translation shifts a figure in a specific direction without altering its size or shape.
So, the transformation that changes the size of a figure is dilation.

Identify the vertex and the y-intercept of the graph of the function.
y = –0.25(x – 4)^2 2 – 2
vertex, (2, –4); y-intercept, –6
vertex, (–4, 0); y-intercept, –6
vertex, (4, –2); y-intercept, –6
vertex, (–2, 4); y-intercept, –6
Answer:
vertex, (4, –2); y-intercept, –6
Step-by-step explanation:
The equation is written in vertex form [tex]y = a(x-h)^2 + k[/tex] where the vertex is (h,k).
The vertex here is (4, -2). This means the solution is vertex, (4, –2); y-intercept, –6.
Answer:
vertex, (4, –2); y-intercept, –6.
Step-by-step explanation:
[tex]y=-0.25(x-4)^{2}-2[/tex]
[tex]y=-0.25(x^{2}-8x+16)-2[/tex]
[tex]y=-0.25x^{2}+2x-4-2[/tex]
[tex]y=-0.25x^{2}+2x-6[/tex]
the vertex is [tex](\frac{-b}{2a},y(\frac{-b}{2a}) )[/tex] where a=-0.25 and b=2. So,
[tex]\frac{-b}{2a}= \frac{-2}{-0.5}=4[/tex]
[tex]y(\frac{-b}{2a})=-0.25(4)^{2}+2(4)-6= -4+8-6=-2 [/tex]
Then, the vertex is (4,-2) and the intercept is y(0)= -0.25(0)+2(0)-6 = -6. So, the answer is the third option.

Carl plans to prepare for the upcoming track season by running 160 miles. So far he has ran 28 miles. How many more miles does he have to run?
Answer:
132 miles
Step-by-step explanation:
miles ran + miles to run = total miles
28 + miles to run = 160
Subtract 28 from each side
28-28 + miles to run = 160-28
miles to run = 132
He still need to run 132 miles
Answer:
132 mi
Step-by-step explanation:
since he ran 28 miles but he has to run 160 miles, he still has to run some miles. if we make the amount he still has to run x, we can do 28+x=160. now we can solve this by subtracting 28 on both sides to getx=132
28+x=160

What is a car loan ?
Answer:
A loan that you usually have to get from a bank to use specifically for paying for a car,which you later have to pay back
Step-by-step explanation:
A car loan is a type of secured loan, where we can say that the car we buy is collateral for the loan.
In case of failure of payment of loan, the lender can repossess the car and sell it to pay off the loan.
In other words, we can say the lender or banks purchase the car for us and gives us few years time to pay back that loan.
The loan is granted with interest rates, that one has to pay above the principle amount during the tenure of the loan.
