Day of Measurement 8 16 Height (cm) 42.2 59.0 69.5 88.4 98.9 21 30 35 What is the average rate of growth of the plant, in centimeters per day, from the 16th day to the 30th day? O A 2.95 cm B. 3.30 cm C. 2.10 cm D. 1.96 cm ​

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.

Answer:

1. Not proportional 2. is proportional. For 3, 4, 5, and 6 just plot them.

Step-by-step explanation:

For 1, y intercept/x intercept is not 0 when you graph, thus not proportional. Number 2 is, thus proportional. For 3, 4, 5, and 6 you would plot them accordingly. So for (-5, -2) Start as 0,0 and go 5 to the left as it's negative, and 2 down as it is also negative. Do the same for others.

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8

Answer:

3x-x=15+1

2x=16

x=16/2

x=8

Answer:

JKLM is similar to ABCD

Step-by-step explanation:

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:

The number is 7

Step-by-step explanation:

let the said number be x

Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

Thus;

6x - 19 = 16 + x

6x-x = 16 + 19

5x = 35

x = 35/5

x = 7

Answer:

14. 4 + x - 2

15. 8k - 3k

16. 5 + 2y + 15

Step-by-step explanation:

14. "sum" means adding, "minus" means subtract

sum of four and x: 4 + x

minus two: 4 + x - 2

15. "product" means multiplying, "decreased by" means subtract, "times" means multiply

the product of k and 8: 8k

three times k: 3k

the product of k and 8 decreased by three times k: 8k - 3k

(Depending on what the question is asking, you may or may not need to simplify this to 5k (8k - 3k = 5k))

16. "more" means add, "plus" means add, "twice" means multiply by two

five: 5

plus twice y:  5 + 2y

fifteen more: 5 + 2y + 15

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.

Answer:

4c-20= 4

+20  +20

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

x = 14
