M=y2-y1/x2-x1

Answer:

4/3

Step-by-step explanation:

Use the formula

x2-x1 over y2-y1

since it goes by (x,y) label the given points

(6,7) and (10,10)

6 is your first x (x1)

7 is you first y (y1)

onto the next point...(10,10)

10 would be your second x (x2)

and your second y would also be 10 (y2)

Now plug into formula x2-x1 over y2-y1

10-6 over 10-7= 4/3

Ronald said that (8.0 × 107) + (6.2 × 103) = 14.2 x 1010. Amy added the numbers too and said the sum was 8.00062 × 107. Ronald then added the numbers a second time and came up with his original result. Whose solution is correct? Ronald is correct because 80,000,000 + 6,200 = 142,000,000,000.

Yes No B
Amy is correct because adding the decimals and then adding the exponents is not the correct procedure for adding numbers in scientific notation.

Yes No C
Amy is correct because 6.2 × 103 is a much smaller number than 8.0 × 107, so the sum of the two numbers cannot be as large as a decimal times 1010.

Yes No D
Ronald is correct because when you add the exponents in 107 and 103, you get 1010.

express 20cm as a percentage of 3m.
give your answer as a mixed number

Answers

Answer:

[tex]6\frac{2}{3}[/tex] %

Step-by-step explanation:

First, convert 3 meters into centimeters.

1m = 100cm

3m = 100 × 3 = 300cm

Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.

[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex] ⇒ Simplify your fraction to its simplest terms.

Next, multiply your simplified fraction by 100 to get your percentage.

[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] % ⇒ Simplify your percentage to its simplest terms.

Hope this helped! I would really appreciate it if you would please mark me brainliest!

20cm as a percentage of 3m as a mixed fraction is 6 2/3 %

let's convert centimetre to metre

1 cm = 0.01 m

20 cm = ?

cross multiply

length in metre = 20 × 0.01 = 0.2 m

Therefore,

0.2 m as a percentage of 3m is as follows:

0.2 / 3 × 100 = 20 / 3 = 6 2 / 3 %

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y

Answers

Answer:

I attached a pic of the answer. I just did the quiz. Hope this helps!!!

Step-by-step explanation:

The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Given that,
To determine the graph of the polynomial function h(x) = x³ + 2x² - 11x -12.

What is the graph?

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups and down,
So the graph can be drawn as shown in the image.

Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

If ZMK APY, m M = 112 ° , m Y = 41 ° , m K = (13x 37) ° , and m A = (2y + 7) ° , find the values of x and y.

need a answer asap

Answers

Answer

13x-37=112

13x =149

X=11.4

2y+7=41

Y=24

The value of x and y respectively will be 13° and 17°.

Based on the equation that's given in the question, the value of x will be found thus:

13x - 37 = 112

Collect like terms

13x = 112 + 37

13x = 149

x = 149/13

x = 13

Also, note that 2y + 7 = 41, therefore, the value of y will be:

2y = 41 - 7

2y = 34

y = 34/2 = 17°

Therefore, the value of x and y respectively will be 13° and 17°.

Answer:

y= -2x + 80

Step-by-step explanation:

First, you need to find the slope, which can be done by subtracting the change in y over the change in x. The easiest points to pick are (30,20) and (40,0). Do 20-0 which is -20, then divide that by 40-30, and you get -2. Then to find the y intercept, pick a point (like 40,0). Then do 0 = -2(40) + b, and solving for b you get 80.

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x

x≥x+32

x6≤x2−1

x+4≥x3

Answers

Answer: A

Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3

The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.

What is inequality?

inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

The inequality 3(x-1) ≤ 4x will be solved as below:-

3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3. The complete solution is given below:-

3(x-1) ≤ 4x

3x - 3 ≤ 4x

-3 ≤ 4x - 3x

-3 ≤ x

x ≥ -3

Therefore, the inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
