y=-3+21
Step-by-step explanation: (I can't sketch the graph for you)
First you need to find the slope of the line passing through the points (5,4) and (-7,0). This can be done using the point-slope form of a line.
Point 1: (-7,0)
Point 2: (5,4)
y2-y1=m(x2-x1)
m= (y2-y1)/(x2-x1) = (4-0)/(5-(-7)) = 4/12= 1/3
Now, when two lines are perpendicular, they are negative recopricols. So the slope of the line would be -3.
Since the equation of the line you are trying to find passes through the point (4,9), using point-slope formula again and solve for y.

Answer:
1
Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.
Find each difference. If you get stuck, consider drawing a number line diagram.

3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59

Find the derivative of f(x) = negative 8 divided by x at x = 11.
Answers
Answer: I think it’s
f ` (x) = - 8 / x²
f ` (11) = - 8 / 121
The value of the derivative at x = 11 is 8/121
The equation of the function is given as:
[tex]f(x) = -\frac 8x[/tex]
Rewrite the above equation as:
[tex]f(x) = -8x^{-1}[/tex]
Using the first principle, the derivative of f(x) is:
[tex]f'(x) = -1 \times -8x^{-1-1}[/tex]
[tex]f'(x) = -1 \times -8x^{-2}[/tex]
Evaluate the product
[tex]f'(x) = 8x^{-2}[/tex]
Rewrite the above equation as:
[tex]f'(x) = \frac{8}{x^2}[/tex]
Substitute 11 for x
[tex]f'(11) = \frac{8}{11^2}[/tex]
[tex]f'(11) = \frac{8}{121}[/tex]
Hence, the value of the derivative at x = 11 is 8/121

Answer: (x,y) -> (x,-y)
Step-by-step explanation:
If you take any point, for example (-1,1) from the blue shape, you have to multiply the y value by -1 to get to (-1,-1) for the red shape. You can test it out with any point on the two figures.
Also, by looking at it, you can see that it is a reflection over the x axis and a reflection over the x axis always just multiplies the y value by -1.

4c= 24
/4 /4
c= 6
Answer:
c = 1 btw can i be brainiest...
Step-by-step explanation:
First, rewrite the left side of the equation and group and combine like terms:
c + (4 − 3c) − 2 = 0
c + 4 − 3c − 2 = 0
−3c + c + 4 − 2 = 0
−3c + 1c + 4 − 2 = 0
(−3 + 1) c + (4 - 2) = 0
−2c + 2 = 0
Next, subtract
2
from each side of the equation to isolate the
c
term while keeping the equation balanced:
−2c + 2 − 2 = 0
−2 − 2c + 0 = −2
−2c = −2
Now, divide each side of the equation by
−2
to solve for
c
while keeping the equation balanced:
−2c - 2 = −2 − 2
−2c − 2 = 1
c = 1

Answer:
x = 14
Step-by-step explanation:
First, organize your work by showing that lines are similar
Line KV is similar to line RV
Line UV is similar to line LV
etc, etc.
=========================================
Now notice that line KV and line RV have the numbers 9 and 18 accordingly
and notice that it's an x2 difference.
==============================================
Now apply the same thing to line UV and LV and divide 26 by 2
That gets us 13
=======================================
Now plug 13 into the equation (2x - 15)
2x - 15 = 13
==========================================
Now solve for X
2x - 15 = 13
Add 15 to each side
2x − 15 + 15 =13 + 15
2x = 28
Divide both sides by 2
2x / 2 = 28 / 2
