Answer:

Step-by-step explanation:

38 - 21 = 17
21 - 4 = 17
The difference between each pair of numbers above is 17, so that is the common difference.

I hope this helps!

Only problem 6a. Can someone demonstrate how to do this so I can do the rest solo?

Lisa [10]

as far as I can tell, is simply asking to write two more expressions, that are equivalent to the provided one, namely, grab the provided one and expand it, if you simplify the expanded version, you'd end up with the provided, for example

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}}\\\\\\\boxed{6a.3}~\hfill \stackrel{ch anging}{\cfrac{15\div 3}{30\div 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15\div 5}{30\div 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

so let's do 6a1, 6a3 and 6a5.

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}} \\\\\\ \boxed{6a.3}~\hfill \stackrel{changing}{\cfrac{15\div 3}{30\div 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15\div 5}{30\div 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

$\bf \boxed{6a.5}~\hfill \stackrel{changing}{(9\cdot 10)\div (2\cdot 10)}\implies \stackrel{one}{90\div 20}~\hfill \stackrel{changing}{(9\cdot 70)\div(2\cdot 70)}\implies \stackrel{two}{630\div 140}$

Write an equation of the line that passes through the given point P and

dexar [7]

Answer <u>(assuming it can be in point-slope form)</u>:

$y-4 = 3(x+2)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ , to write the equation of the line in point-slope form. Substitute x and y values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 3 for it. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, take the x and y values of point P and substitute them into the equation as well. Substitute -2 for $x_1$ and 4 for $y_1$ . This gives the following answer:

$y-4 = 3(x+2)$

What is the area of a rectangle with vertices at (−3, −1) , (1, 3) , (3, 1) , and (−1, −3) ?

kondaur [170]

The length of the side joining points (-3, -1) and (1, 3) is given by

$l= \sqrt{(1+3)^2+(3+1)^2} \\ \\ = \sqrt{4^2+4^2} = \sqrt{16+16} \\ \\ = \sqrt{32}$

The length of the side joining points (1, 3) and (3, 1) is given by

$w= \sqrt{(3-1)^2+(1-3)^2} \\ \\ = \sqrt{2^2+(-2)^2} = \sqrt{4+4} \\ \\ = \sqrt{8}$

The area of a rectangle is given by length times width.

Thus, the area of the given rectangle is given by

$Area=l\times w \\ \\ = \sqrt{32} \times \sqrt{8} \\ \\ = \sqrt{32\times8} = \sqrt{256} \\ \\ =\bold{16} \ units^2$
