For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicu
Nat2105 [25]

Answer/Step-by-step explanation:

Given,

10x - 3y = 3

3x + 10y = 30

Rewrite both equation in slope-intercept form, y = mx + b.

Where, m = slope of the line.

Thus,

✔️10x - 3y = 3

-3y = -10x + 3

y = 10/3x - 1

Slope of this line would be 10/3

✔️3x + 10y = 30

10y = -3x + 30

y = -3/10x + 3

The slope of this line is -³/10.

✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.

What is the common denominator of -1/y and 2/5y
Anarel [89]
-1/y = 2/5y. The change from -1 to 2 would be -2, so we now that the change from y to 5y would also have to be -2. -2 = -10 so you multiply by 5. After doing the same to the top you would come to the conclusion that the LCD would be 5y.  Hope this helps!

What is the value of x
Gemiola [76]
For this case, we observe that the triangles are similar.
 We observe that the triagnules have three equal angles.
 Therefore, to find the value of x we can use the following relationship:
 x / 15 = 5/12&#10;
 Clearing x we have:
 x = (5/12) * (15)&#10;&#10;x = 6.25
 Answer:
 
The value of x is given by:
 
x = 6.25

If (x − 2)^2=49, then x could be ?
Ket [755]
(x - 2)^2=49\\ \\ x^2-4x +4 -49=0\\ \\x^2-4x -45 = 0\\ \\\Delta = b^{2}-4ac =  (-4)^{2}-4*1* (-45)= 16+180=196  \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{4-\sqrt{196}}{2}=\frac{4-14}{2}=\frac{-10}{2}=-5 \\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{4+\sqrt{196}}{2}=\frac{4+14}{2}=\frac{18}{2}=9 \\ \\Answer : \ x=-5 \ or \ x= 9
