Answer:

20

Step-by-step explanation:

Since we know that it takes 5lbs. to break a 2-foot longboard, we first want to figure out how many pounds it takes to break a 1foot board.

5/2=2.5

It takes 2.5 lbs to break a 1-foot board.

2.5x8=20

It would take 20lbs to break an 8-foot longboard.

Hope this helps :)

Find an equation for the line that passes through the points (-4.-2) and (5,1)
skelet666 [1.2K]

Answer:

y= \frac{1}{3}x-\frac{2}{3}

Step-by-step explanation:

The first step to making an equation of a line is finding the slope. To do this, we can use the point slope formula: \frac{y_2-y_1}{x_2-x_1}

In this case,

y2=1

y1= -2

x2=5

x1= -4

plug this into the formula: \frac{1-(-2)}{5-(-4)}, which gives us 3/9, or 1/3 as the slope.

Now we have the equation y=1/3x+b. Let's find b! We can do this by plugging in one of the points into our new equation, let's use (5,1)

1=y, 5=x

1=\frac{1}{3}(5)+b

b= -\frac{2}{3}

now, we plug b= -2/3 into our equation, and we finally get y= \frac{1}{3}x-\frac{2}{3}

4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5
CaHeK987 [17]
ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
6 {x}^{2}  - 6x + 5



EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.


The highest degree of the polynomial is considered the degree of the polynomial.



For first option,
4 {x}^{3}  - 2x + 10
the highest degree is 3.



The second option is,
{x}^{2}  - 8 {x}^{3}  + 3
This polynomial also has a degree of 3.



The third option is,
6 {x}^{2}  - 6x + 5
This last option has a degree of 2.


Therefore the correct answer is option C.
