The equation of the line that has a slope of -1 and a y-intercept of -6 is:
y=-1x-6.
Step-by-step explanation: here is the explanation
You want to find the equation for a line that has a slope of -1 and a y-intercept of -6.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
All you really have to do here is
replace m with -1, which is the slope you gave, and
replace b with -6, the y-intercept you gave,
in the equation y=mx+b.
The equation of the line that has a slope of -1 and a y-intercept of -6 is:
y=-1x-6.

In triangle ABC, a = 3, b = 5, and c = 7. Find the measure of B.
158°
142°
38°
22°
Answer:
C
Step-by-step explanation:
Since we are given three sides and we want to find an angle, we can use the law of cosines.
The law of cosines is given by:
[tex]b^2=a^2+c^2-2ac\cos(B)[/tex]
In this case, a = 3, b = 5, and c = 7. Therefore:
[tex](5)^2=(3)^2+(7)^2-2(3)(7)\cos(B)[/tex]
Evaluate:
[tex]25=58-42\cos(B)[/tex]
Therefore:
[tex]-42\cos(B)=-33[/tex]
Dividing both sides:
[tex]\displaystyle \cos(B)=\frac{33}{42}[/tex]
And by taking the inverse cosine of both sides:
[tex]\displaystyle \angle B=\cos^{-1}\Big(\frac{33}{42}\Big)=38.2132...\approx 38^\circ[/tex]
Our answer is C.

A online video-streaming services charges a one-time membership fee of $20 and a monthly fee of $7.50. How many months of membership will $115 pay for
Answer:
Number of months= 12 months
Step-by-step explanation:
Giving the following information:
One time fee= $20
Monthly fee= $7.5
Total cost= $115
To calculate the number of months, we need to use the following formula:
Number of months= (total cost - one time fee) / monthly fee
Number of months= (115 - 20) / 7.5
Number of months= 12.67
Number of months= 12 months
If the graph of the function moves to the right two units what is the new vertex of the function
Answer:
Let's talk through this a one step at a time.
*Since f(x) is concave-up with its vertex on the x-axis, we know f(x) ≥ 0.
*We also know that when we shift a function's domain by a positive number, we shift the function left and when we shift a function's domain by a negative number, we shift the function right. So f(x-5) is f(x) shifted to the right by 5.
*At this point, f(x-5) has its vertex at (5,0).
*When we negate f(x-5), the parabola becomes concave down yet the vertex remains at (5,0). Now we're at -f(x-5). At this point we have -f(x-5)≤0 with a range (-∞,0]
*If we add 2 to create g(x)=2-f(x-5), then we have a concave down parabola with its vertex shifted up by 2, at (5,2). So, g(x) is concave down with its vertex at (5,2). Hence
What do the h and k in the equations of a circle represent?
Answer:
H and K in the equations of a circle represents the coordinates of it's center point.
Step-by-step explanation:
The variables h and k represent the coordinates of the center of the circle
In the equations of a circle in standard form, [tex](x - h)^2 + (y - k)^2 = r^2[/tex].
The value of h corresponds to the x-coordinate of the center, while the value of k represents the y-coordinate of the center. The center of the circle is denoted as (h, k).
By specifying the values of h and k, we can determine the exact location of the center of the circle on the coordinate plane. These coordinates help identify the position of the circle in relation to the x and y axes.
For example, if the equation of a circle is [tex](x - 2)^2 + (y + 3)^2 = 16[/tex], the center of the circle is located at the point (2, -3), with h = 2 and k = -3.
Understanding the significance of h and k allows us to identify the center of a circle and provides valuable information for analyzing and graphing circles in the coordinate plane.
Therefore, the variables h and k represent the coordinates of the center of the circle

URGENT, PLEASE ANSWERR If someone who is 5 feet tall uses a potato gun to shoot a potato in the air at 100 feet per second, we can use the function ℎ()=−162+100+5 to calculate how far the potato will be from the ground at any given second (t). What does the h(0) represent in the context of the problem?
Given:
Consider the function is:
[tex]h(t)=-16t^2+100t+5[/tex]
This function is used to calculate how far the potato will be from the ground at any given second (t).
To find:
The value of h(0) and its meaning in the context of the problem.
Solution:
We have,
[tex]h(t)=-16t^2+100t+5[/tex]
At t=0,
[tex]h(0)=-16(0)^2+100(0)+5[/tex]
[tex]h(0)=0+0+5[/tex]
[tex]h(0)=5[/tex]
Therefore, the value of h(0) is 5. It means the potato is 5 feet from the ground at the time of shooting.

Answer:
It should be 1000 miles
Step-by-step explanation:
If you draw the picture out, you will find as the x-axis part is the same, so the distance will simply be 12 -2 = 10 units, and 1unit = 100 miles, so distance is 100 * 10 = 1000 miles.

please I need someone to help my assignment
Answer: x = 10
Step-by-step explanation:
The Pythagorean's theorem says that for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:
A^2 + B^2 = H^2
In this case, we have:
A = (x - 4)
B = (x - 2)
H = x
Then we have the equation:
(x - 4)^2 + (x - 2)^2 = x^2
Now we need to solve this for x, first let's simplify it.
(x^2 - 2*x*4 + 16) + (x^2 - 2*2*x + 4) = x^2
2*x^2 - 12*x + 20 = x^2
2*x^2 - 12*x + 20 - x^2 = 0
x^2 - 12*x + 20 = 0
The solutions of this equation are given by the Bhaskara's equation, such that for an equation like:
a*x^2 + b*x + c = 0
The solutions are:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]
Then the solutions for our equation are:
[tex]x = \frac{-(-12) \pm \sqrt{(-12)^2 - 4*1*20} }{2*1} = \frac{12 \pm 8 }{2}[/tex]
Then the two possible solutions are:
x = (12 - 8)/2 = 4/2 = 2
Notice that if x = 2, then the length of the catheti will be:
A = 2 - 4 = -2
B = 2 - 2 = 0
This has no sense, so we can discard this solution.
The other solution for x is:
x = (12 + 8)/2 = 10
x = 10
Then:
H = 10
A = 10 - 4 = 6
B = 10 - 2 = 8
This solution makes sense, then x = 10.
