Answer:
Please check the explanation
Step-by-step explanation:
Given the points
(-5,-7) (3,1)Determining the slope between the points:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-7\right),\:\left(x_2,\:y_2\right)=\left(3,\:1\right)[/tex]
[tex]m=\frac{1-\left(-7\right)}{3-\left(-5\right)}[/tex]
[tex]m=1[/tex]
Writing the equation in point-slope form
As the point-slope form of the line equation is defined by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
Putting the point [tex](-5,-7)[/tex] and the slope [tex]m = 1[/tex] in the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)\\[/tex]
Hence, the equation in the point-slope form will be:
[tex]y-\left(-7\right)=1\left(x-\left(-5\right)\right)[/tex]
Writing the equation in slope-intercept form
As the point-slope of the equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Putting m = 1 and (3, 1) to determine the y-intercept
[tex]y = mx+b[/tex]
[tex]1 = 1 (3) + b[/tex]
[tex]1 = 3 + b[/tex]
[tex]b = -2[/tex]
so putting [tex]b=-2[/tex] and m = 1 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y = (1)x + (-2)[/tex]
Therefore, the equation in slope-intercept form is:
[tex]y = x -2[/tex]
Writing the equation in the standard form form
As we know that the equation in the standard form is
[tex]Ax+By=C[/tex]
where x and y are variables and A, B and C are constants
As we already know the equation in slope-intercept form
[tex]y = (1)x + (-2)[/tex]
so just simplify the equation to write in standard form
[tex]y = (1)x + (-2)[/tex]
[tex]y = x - 2[/tex]
[tex]y - x = -2[/tex]

A company manufactures acoustic guitars. The table shows the number of units that the company sold each month over a nine-month period beginning in January. Which equation best models the situation?
Answer:
i need this asap
Step-by-step explanation:
The equation that models the situation; [tex]y = 148.4 \sqrt {x-1} +154[/tex] Thus, option B is correct.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
A company manufactures acoustic guitars.
The table shows the number of units that the company sold each month over a nine-month period beginning in January, that is;
Month, x 1 2 3 4 5 6 7 8 9
Units, y 150 300 380 425 425 480 520 550 575
If we put x = 2
[tex]y = 148.4 \sqrt {2-1} +154\\\\y = 148.4 +154 = 302.4[/tex]
Y = 300 ( approx)
We can see that the equation that models the situation;
[tex]y = 148.4 \sqrt {x-1} +154[/tex]
Thus, option B is correct.

Step-by-step explanation:
I need to know which ones are nonlinear or nonproportion
Nonlinear means that -- the graph isn't exactly the line. It's basically a "curve" like parabola.
Non-proportional means that --- the graph doesn't start from the origin point or doesn't start at (0,0).
( A ) is both linear and proportion.
( B ) is proportion BUT NOT LINEAR (It's curved.)
( C ) is linear and proportion.
( D ) Is linear BUT NOT PROPORTION (Doesn't start at (0,0) )
So ( B ) and ( D )

Two sides of an isosceles triangle measures 10 and 10. What is true about the third side?
a. -10
d. < 20
Answer:
Step-by-step explanation:
Sum of length of any two sides of a triangle is greater than length of third side.
(d). < 20
The measure of the third side of the triangle is < 20, the correct option is D.
What is an Isosceles Triangle?An Isosceles triangle is a triangle whose two sides are equal in length, and so two angles are also equal in measure.
The isosceles triangle has equal side of 10.
According to the theorem,
The length of the third side is always less than the sum of the two sides of a triangle.
Let the third side be x
Then,
x < 10+10
x < 20

C) the triangles are congruent
Step-by-step explanation:
Answer:
c. the triangles are congruent
Step-by-step explanation:
Both the triangles are right triangles which means the square thing at the bottom corner of the triangles are 90 degrees. So with this info, a triangle is 180 degrees, and one of the triangles already gave u one of the corners degrees so
90 + 59 + x =180
149 + x = 180
x = 31, so now the left triangle is solved. Now see the 118 degrees in the middle? A straight line is 180 degrees so with this in mind,
31 + 118 + x = 180
149 + x = 180
x = 31
The right triangle also has 31 and 90 as two of its angles, we don't need to calculate to know the last angle left is 59 like the left triangle. Therefore both triangles are congruent as they are the same.
