URGENT! LAST QUESTION OF MY HW! I've reposted this multiple times but no one has answered, please leave an explanation if you know the answer. I will give Brainliest!
Answers
Answer:
y=5
Step-by-step explanation:
Any equation that's y=c (or any other constant) is a horizontal line. Imagine a parabola and a horizontal line plotted on a graph.
There are three possibilities of where the horizontal line can be:
It may not touch the parabola at all,
It may touch the parabola at one specific point (it's a tangent line)
Or it may touch the parabola at two points (it's a secant line)
The question prompt tells us that the horizontal line y=c touches the parabola at exactly one point; so for it not to touch two points it has to touch the parabola at the vertex point, right?
If we graph the parabola (or we could just look at the equation and it should be intuitive), we find out that the y-intercept is 5. In other words the point where the function reaches its maximum value (maxima) is at y=5.
For this reason, the value of c is 5 since if it was any value below that it would touch more than one point and if it was above it it wouldn't touch any point.
Here's an image so that it'll be a bit clearer hopefully:
Good luck!

Solve the equation for m. Show your work on the canvas. Move -n by using opposite operation. Then just write the equation as is. This is a one step equation. 4=m−n
Answers
Answer:
m = 4+n
Step-by-step explanation:
Given the expression 4 = m-n, we are to make m the subject of the formula
From the equation
4 = m-n
Rearrange
m-n = 4
Add n both sides of the equation
m-n+n = 4+n
m+0 =4+n
m = 4+n
Hence the expression for m is given as m = 4+n

To find:
The simplified form of the given expression so there is only one positive power for the baser -5.
Solution:
We have,
[tex](-5)^7\div (-5)^2[/tex]
[tex]=\dfrac{(-5)^7}{(-5)^2}[/tex]
Using the properties of exponents, the given expression can be written as
[tex]=(-5)^{7-2}[/tex] [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]
[tex]=(-5)^{5}[/tex]
Here, the base is -5 and the exponent is 5.
Therefore, the correct option is C.

Answers
Answer:
x=13
Step-by-step explanation:
According to the question
3x+5x-14=90
8x-14=90
8x=90+14
8x=104
x=104/8
x=13
180 - 90 + 14 = 3x + 5x
104 = 8x
104/8 = x
x = 13
Checking:
3(13) + 90 + 5(13) - 14 = 180
180 = 180
So x=13

Find the equation of the straight line which passes through the point (2,3) and is
inclined at 30° to the positive direction of the x-axis.
Answers
Answer: y = 1.73*x - 0.46
Step-by-step explanation:
For a linear equation of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:
Tan(A) = a.
in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:
A + 30° = 90
A = 90° - 30° = 60°
Then the slope is:
a = Tan(60°) = 1.73
Then we have the equation:
y = 1.73*x + b
And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.
3 = 1.73*2 + b
3 - 1.73*2 = b = -0.46
Then the equation is:
y = 1.73*x - 0.46
2x + 3y = -1

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?
Answers
Answer:
7
Step-by-step explanation:
6,300 divide by 900 would equal 7
Answer:
7 beams
Step-by-step explanation:
To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:
6,300 ÷ 900 = 7
So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Help!!!!!! Find x and y so the quadrilateral is a parallelogram.
Answers
Answer:
Conclusion:
The value of x = 7The value of y = 4Step-by-step explanation:
Given
The parallelogram PQRSWe know that the diagonals of a parallelogram bisect each other.
Therefore,
RT = TPGiven RT = x and TP = 5x-28, so
x = 5x-28
5x = x+28
5x-x = 28
4x = 28
divide boh sides by 4
4x/4 = 28/4
x = 7
Thus, the value of x = 7
Similarly,
QT = TS
Given QT = 5y and TS = 2y+12, so
5y = 2y+12
5y-2y = 12
3y = 12
divide both sides by 3
3y/3 = 12/3
y = 4
Thus, the value of y = 4
Conclusion:
The value of x = 7The value of y = 4find the midpoint between the points in the graph.

write an equation in slope-intercept form perpendicular to the given equation through the given point
Y = -3x + 4
(6,-2)
Answers
Answer:
y = (1/3)x - 4
Step-by-step explanation:
Any line perpendicular to the given equation y = -3x + 4 will have a slope which is the negative reciprocal of -3; that is, +1/3.
Start with the general slope-intercept form y = mx + b.
Insert the coordinates 6 and -2 into y = mx + b: -2 = (1/3)(6) + b, or
-2 = 2 + b. Thus, b = -4, and the desired equation is
y = (1/3)x - 4
