Hello,


The answer is Its diagonals are congruent. Its diagonals are ⊥ to each other.


I believe you can pick more than 1.

Hope this helps

Answer:

(C) and (D)

Step-by-step explanation:

From the properties of rhombus, we know that the diagonals are always congruent and the diagonals are perpendicular to each other.

Thus, only options (C) and (D) are correct as rest of the two options are not true regarding the properties of rhombus.

Hence, option C and D are true about rhombus.

(5,1); m=2 write an equation of the line
gtnhenbr [62]
Hey there! :) 

To find an equation of a line that passes through (5, 1) and has a slope of 2, we'll need to plug our known variables into the slope-intercept equation.

Slope-intercept equation : y = mx + b ; where m=slope, b=y-intercept

Since we're already given the slope, all we really need to do is find the y-intercept.

We can do this by plugging our known values into the slope-intercept equation.

y = mx + b

Since we're trying to find "b," we need to plug in "y, m, x" into our formula.

(1) = (2)(5) + b

Simplify.

1 = 10 + b

Subtract 10 from both sides.

1 - 10 = b

Simplify.

-9 = b

So, our y-intercept is 9! 

Now, we can very simply plug our known values into slope-intercept form.

y = mx + b

y = 2x - 9 → final answer

~Hope I helped!~

1. X3,    15x - 10y = 80   15x - 7y = 51

-17y = 29

2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333

  6 = 1/80 + b. 6 - 1/80 =  5.9875

                                         13.9708333333

3. I genuinely dont know sorry.

4. Pencil = $0.05. Pen = $1.05

An arithmetic sequence with a thrid term of 8 and constant difference of 5
olga nikolaevna [1]
\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
d=5\\
a_3=8\\
n=3
\end{cases}
\\\\\\
a_3=a_1+(3-1)5\implies 8=a_1+(2)5\implies 8=a_1+10
\\\\\\
\boxed{-2=a_1}
\\\\\\
a_n=-2+(n-1)5

Plz help i kind of forgot how to do this<br> its just a review should be easy
Jet001 [13]
This is easy just find out what 5^2 equals which will be 5x5=25 (when dealing with a squared number you will always times it by itself. so if you had 10^2 it would be 100.) so now that we know 5^2 is 25 we then can add the 20 which gets 25+20=45! Hope this helps!
