Answer:

Speed of Puck is 18 m/s

Step-by-step explanation:

Mathematically;

speed = distance/ time

The puck traveled a distance of 27 m in 1.5 seconds

The speed of the puck is thus;

27/1.5 = 18 m/s

Answer:

(a+b)(2x−ab+a−b)+x(a−b)+x²

Step-by-step explanation:

I can't make a good explanation, so here's a graph.

Also, this wouldn't be a proportional relationship because of exponents on the last term.

This is really a parabola.

Answer:

because the coefficient is positive

Answer:

[tex]y=-2x+3[/tex]

Step-by-step explanation:

Equation of straight line in slope intercept form is given as

[tex]y=mx+b[/tex]

Here

Slope of line m=-2 (for every one step on x-axis line going down 2 step on y-axis)

y-intercept b=3

[tex]y=-2x+3[/tex]

Step-by-step answer:

-1/5n+7=2

-1/5n+7-7=2-7

-1/5n=-5

Answer:

The length of rectangle is 78 and width is 46

Step-by-step explanation:

Let l be the length of rectangle and w be the width of rectangle

Then according to given statement

"The length and width of a rectangle  added together is 124"

[tex]l+w = 124[/tex]  Eqn 1

And

[tex]l-w = 32[/tex]    Eqn 2

The equation form a system of linear equation in two variables. We can use different methods to solve he system.

We will use the elimination method

Adding equation 1 and equation 2

[tex]l+w+l-w = 124+32\\2l = 156\\\frac{2l}{2} = \frac{156}{2}\\l = 78[/tex]

Putting l = 78 in equation 1

[tex]78+w = 124\\w = 124-78\\w = 46[/tex]

Hence,

The length of rectangle is 78 and width is 46

Answer:

The answer is "Option C".

Step-by-step explanation:

The census is meant to count a whole population of a nation and the place, where everyone normally lives. It is a statistical method, which analyses all groups or components of its community used then for a specific particular population so not all representatives with this population. It try to collect data from everybody in the community and we're doing a census.

Answer:

x=-2 would be a straight line right through -2 on the x-axis

Step-by-step explanation:

Answer:

a straight line going up and down by the x axis -2

______________________________

Note:

 - When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.

Equation at the end of Step 1:

Note:

 - The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.

 - The y(k) changes from [tex]+(-6)[/tex] to [tex]-6[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.

So the answer is c, [tex]\bold{y=\frac{3}{x-6}-6}[/tex].

10*-8=-80

-80-20 +-100

Answer:

2r+49=-8(-r-5)

-8*-1r   -8*-5

2r+49=8r+40

40-49

2r=8r-9

2r-8r

-6r=-9

r=3/2

Answer:

Put the a with the b

Step-by-step explanation:

Answer:

y=-1/3x+10

Step-by-step explanation:

y=3x+1

The line perpendicular would have a negative reciprocal of the slope of 3 which means that you would add a negative sign and then flip 3/1 into 1/3 resulting in -1/3 as the slope.

To find the line that passes through the point (6,8) you would plug the values into the equation y=mx+b

m=-1/3x as found above

6 is the x-value and 8 is the y-value

8=(-1/3)(6)+b

8=-2+b

Add 2 on both sides and you get b to equal 10  

Answer:

line b

Step-by-step explanation:

line b displays a slope of -1/2

Answer:

Answer:= 87.50m

Step-by-step explanation: base × height ÷2

                                                25 ×  7     ÷    2

                                                175      ÷ 2  

                                              =   87.50

Answer:

[tex]3(x + 4) = 27 \\ (x + 4) = \frac{27}{3} \\ (x + 4) = 9 \\ x = (9 - 4) \\ \boxed{x = 5}✓[/tex]

Answer:

the answer is 5 because when you do PEMDAS 5+4 is 9 and then when you do 3×9 you get 27.

Step-by-step explanation:

x=5

410/27 cubic yards/meters = 15.19
