Line x has a slope of -1/2. Line y is perpendicular to line x. What is the slope of line y?
Answer:
2
Step-by-step explanation:
perpendicular means the opposite inverse of a slope. So -1/2 will become 2/1 or simply 2.
opposite means the sign will change, negative becomes positive and positive becomes negative.
inverse flip numerator and denominator.
[tex]\huge\boxed{Hi\;there!}[/tex]
★Perpendicular lines have slopes that are opposite reciprocals.
This means we take a number, change its sign, and then, flop it over:
[tex]\displaystyle-\frac{1}{2}[/tex]
[tex]\displaystyle\frac{1}{2}[/tex]
[tex]2[/tex]
[tex]\huge\boxed{\mathfrak{Answer:{\boxed{the\;slope\;of\;line\;y\;is\;2}}}}}[/tex]

What value of x makes the equation -0.2(3x – 25) = -0.1x + 7 true?
Answer:
x = -4
Step-by-step explanation:
Ok first let's put the equation.
-0.2(3x – 25) = -0.1x + 7 (first distribute the -.2 to 3x and -25)
-0.6x + 5 = -0.1x + 7 (subtract 5 on both sides)
-0.6x = -0.1x + 2 (add -0.1x on both sides)
-0.5x = 2 (divide by -0.5 on both sides)
x = -4
Hope this helps!!
Give two reasons why it's impossible to draw triangle PQR m angle Q=103^ m angle R=47^ p = 44 q = 12 , and f = 31
Answer:
It is impossible becuase it would not eqaul the numbers a regular triangles would have. A triangle has to equal a certain number and this number does not make a traingle.
Reason 1: The hypotenuse is invalid, because 44^2 does not equal 12^2 + 31^2.
Reason 2: The angles measures do not correlate properly to their assigned letter sides (at least to me). Additionally, 30 degrees just doesn't make any sense from a logical standpoint.

Consider the function shown on the graph. Complete the statements to make them true
Answer:
Domain: x ≥ -5
Range: y ≥ -2
Step-by-step explanation:
The domain are the set of x-values of the function that are plotted on the x-axis. The domain of the graph given are x-values that are equal to or greater than -5.
Therefore:
✅Domain: x ≥ -5
The range from the graph given the y-values plotted on the y-axis against their corresponding x-values that are equal to or greater than -2.
Therefore:
✅Range: y ≥ -2

9/ = 21/28
6/9= /15
Answer:
Step-by-step explanation:
For 2 it is 6/7. 36 and 42 share a common factor, 6. If you divide each one by 6, 36 becomes 6, and 42 becomes 7. So, number 2 is 6/7.

How do you evaluate a division problem
Answer:
Step-by-step explanation:
Not wanting to be trite, i'd still suggest that you use a calculator for routine division. Round off your answer (quotient) to an appropriate number of decimal places.
For example, 2/3 comes out to 0.66666 ... (repeating decimal). You might want to round this off to 2 decimal places: 0.67.
The old fashioned "long division" is another method.
0 . 6
-----------
3 / 2 . 0 0 0
0. 0 0 0
---------------------
1. 8
and so on. You still need to round off the quotient to a suitable number of decimal places.
