Answer:

7/4

Step-by-step explanation:

The slope of the line going through (2,3) and (-2,-4) can be found by:

A) Lining up points

B) Subtracting the numbers vertically

C) Answer: Putting 2nd difference over 1st difference (yes a fraction)

Let's do it!

( 2 , 3)

-( -2 , -4)

--------------

4 7

So the slope is 7/4

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y2-y1} {x2-x1}$

We have as data the following points:

$(x1, y1) = (2,3)\\(x2, y2) = (- 2, -4)$

Substituting in the formula we have:

$m = \frac {-4-3} {- 2-2}$

Equal signs are added and the same sign is placed:

$m = \frac {-7} {- 4}\\m = \frac {7} {4}$

Answer:

$m = \frac {7} {4}$

Explain why x and 4x - 10 are factors of the expression x(4x - 10)3 rather than terms of the expression. What are the terms of t

andriy [413]

Solution :- Let p(x) be the polynomial such that

$p(x) = x(4x-10)^3\\\text{and let f(x) be another polynomial such that }\\f(x)=4x-10\\\text{To find , Put } f(x)=0\\\Rightarrow4x-10=0\\\Rightarrow4x=10\\\Rightarrow x=5/2\\\text{Now substituting value of x in p(x),we get}\\p(x)=\frac{5}{2} .(4(5/2)-10)^3\\\Rightarrow\frac{5}{2}.(10-10)^3=0\\\text{Similarly let g(x)=x ,we get x=0 by putting g(x)=0}\\\text{now f(x)=0 for x=0}\\\text{So by Factor theorem f(x) and g(x) are the factors of polynomial p(x)}\\$

$\text{Now} p(x) = x(4x-10)^3\\=64x^4-480x^3+1200x^2-1000x\\\text{so the terms of terms of } p(x) \text{are} 64x^4,-480x^3,1200x^2,-1000x\\\text{here, by using Factor theorem x is a factor of all the terms but 4x-10 is not. }$

$\text{And the terms of the factor 4x-10 are 4x and -10}$

Scored 72 times out of 150 what percent of his shots did he score?

Sholpan [36]

Whoever scored 72 shots out of 150. Did, In fact, score 48% of their shots.

Solution:
*To calculate the percentage represented by a ratio simply divide the numerator by the denominator and multiply by 100.

72:150 (72/150)

72/150

= 0.48

0.48(100) = 48

... 48%

Is anyone good with triangle inequalities? I provided a picture for the problem.

alisha [4.7K]

Answer:

1 < x < 19

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given the measures y=10, z=9. The third side must satisfy:

10 - 9 < x < 10 + 9

1 < x < 19
