Answer:

$\Huge \boxed{y=3x+6}$

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

The slope can be found from two points.

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

The two points from the graph are (1, 9) and (2, 12).

Plugging in the values and evaluating.

$\displaystyle m=\frac{12-9}{2-1}$

$\displaystyle m=\frac{3}{1}$

$m=3$

The slope of the line is 3.

The y-intercept of the line is where the line cross the y-axis.

The line crosses the y-axis at (0, 6).

$b=6$

The slope-intercept form of the line is:

$y=3x+6$

Put the numbers in order
6,7,15,36,41,43,47,49

Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile

difference of largest value and median.....(49 - 38.5) = 10.5

Which expressions are equivalent to 4d+6+2d4d+6+2d ? Choose all answers that apply: Choose all answers that apply: (Choice A) A

Sliva [168]

Answer:

Options A and C are correct choices.

Step-by-step explanation:

We have been given an expression $4d+6+2d$ and we are asked to choose all the equivalent expressions from given choices.

Let us simplify our given expression.

$4d+6+2d=(4d+2d)+6$

$4d+6+2d=6d+6$

Let us see which of our given choices matches with our answer.

A. $2(3d+3)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$2*3d+2*3$

$6d+6$

Therefore, option A is a correct choice.

B. $6(d+6)$

Upon using distributive property $a(b+c)=a*b+a*c$ we will get,

$6*d+6*6$

$6d+36$

Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.

C. $(3d+3)+(3d+3)$

Upon removing parenthesis we will get,

$3d+3+3d+3$

Upon combining like terms we will get,

$(3d+3d)+(3+3)$

$6d+6$

Therefore, option C is the correct choice.

I dont understand how would i solve this

azamat

So those to angles added together equals 180° thus all you have to add those together and set it equal to 180 to find hat x equals, and then add 89 to it to find the highlighted angle.

x+109+x+89=180

add the numbers and x's together

2x+198=180

subtract 198 from each side

2x = -18

divide each side by 2

x = -9

Put -9 in for x in the equation x+89 to find that angle

-9+89

=80

ANSWER:

That angle equals 80°

I need this really fast can someone help me outMalik jogged 2 miles in 20 minutes. What was his rate in miles per hour?

Blababa [14]

It would be 6 miles per hour.

mph is a unit for speed. And the formula for speed is s=distance /time

So the distance is 2 miles
And the time is 20 minutes

*for this question you need to convert the minutes to hours to get the right units

20mins =0.3 hours (approx) [20/60 to get it in hours]

2 miles/0.3 hours ≈ 6 mph
