Answer:
x^2-10x+25
Step-by-step explanation:
(a+b)^2=a^2+2ab+b^2 so a=x and b=-5 so the expression is x^2-10x+25
Answer:
x^2-10x+25
Step-by-step explanation:
Distribute
(x-5)(x-5)
x(x-5)-5(x-5)
Distribute again
x(x-5)-5(x-5)
x^2-5x-5(x-5)
Distribute one last time
x^2-5x-5(x-5)
x^2-5x-5x+25
combine like terms
x^2-5x-5x+25
x^2-10x+25

Parallel lines have the same slope, while perpendicular lines have an opposite reciprocal slope.
Line 1:
-5y = 3x + 7
y = -3/5x - 7/5
Line 2:
y = -5/3x + 8
Line 3:
6x - 10y = -4
-10y = -6x - 4
y = 3/5x + 2/5
Line 1 and Line 2 are neither perpendicular nor parallel. While their slopes are reciprocals of each other, the signs are not opposite (both are negative).
Line 1 and Line 3 are neither perpendicular nor parallel. While the slope itself is the same, the signs are different.
Line 2 and Line 3 are perpendicular. Their slopes are opposite reciprocals of each other.
Hope this helps!! :)

Solve to find X. 1/5(x - 2) = 1/10 (x + 6)
Answer:
x = 10
Step-by-step explanation:
First, distribute:
[tex]\frac{1}{5} x - \frac{2}{5} =\frac{1}{10} x+\frac{6}{10}[/tex]
Next, subtract [tex]\frac{1}{5}x[/tex] from both sides:
[tex]-\frac{2}{5} = \frac{1}{10} x -\frac{1}{5} x+\frac{6}{10}[/tex]
(multiply [tex]\frac{1}{5}x[/tex] by 2 to get common denominator, [tex]\frac{2}{10} x[/tex] )
[tex]-\frac{2}{5} =-\frac{1}{10}x +\frac{6}{10}[/tex]
Next, subtract [tex]\frac{6}{10}[/tex] from both sides:
[tex]-\frac{2}{5} -\frac{6}{10} =-\frac{1}{10} x[/tex]
(multiply [tex]\frac{2}{5}[/tex] by 2 to get common denominator, [tex]\frac{4}{10}[/tex] )
[tex]-\frac{10}{10} =-\frac{1}{10} x[/tex] ⇒ [tex]-1=-\frac{1}{10} x[/tex]
Next, multiply both sides by 10:
[tex]-10=-x[/tex]
FInally, divide both sides by -1:
x = 10
Answer:
Step-by-step explanation:
1/5(x-2) =1/10(x+6)
1/5x-2 = 1/10x+0.6
1/5x+1/10x= 0.6-2
0.2x+0.1x= -1.4
0.3x= -1.4
x= -4.67
x= -4.7
x= -5

The measure of an angle is 15.8°. What is the measure of its complementary angle?
Answer:
x = 74.2°
Step-by-step explanation:
Complementary angles are two angles whose sum is 90°.
Let x = the second angle
15.8° + x = 90°
x = 90 - 15.8°
x = 74.2°
plsssssssssssss answer
Answer:
Step-by-step explanation:
104 x
---- = ---
50 60
Cross multiply 104 by 60. 6240 is your answer.
Your new equation is 6240 = 50x.
Divide both sides by 50. 6240/50 = x
x = 124.8 mph (miles in one hour)

Find the equation of the line that passes through (-1,2) and is perpendicular to
y
=
1
−
2
x
.
Leave your answer in the form
y
=
m
x
+
c
Answer:
Remember that the slope of perpendicular lines are negative reciprocals of each other.
Step-by-step explanation:
y = 1 - 2x the slope is -2 the value of the x term.
So the slope of the new line using point (- 1, 2) is 1/2.
Now use y = mx + b where y = -1, x = 2, and m = 1/2 .
y = mx + b
-1 = 1/2(2) + b solve for "b", the y-intersect
-1 = 1 + b
-2 = b
The line that is perpendicular to y = 1 - 2x is y = 1/2x - 2

When would the tail of a comet appear to become longer?(1 point)
as it gets farther from Earth
as it gets closer to Earth
as it gets closer to the sun
as it gets farther from the sun
Answer:
As it gets closer to the sun
Step-by-step explanation:
just trust me
The tail of comet will appear to become longer : (c) as it gets closer to sun.
The tail of a comet becomes longer and more pronounced as it gets closer to sun. Comets are made up of ice, dust, and volatile gases. As a comet approaches the sun, the sun's heat causes the ices within the comet to vaporize, creating a glowing coma (a cloud of gas and dust) around the nucleus.
The solar wind and radiation pressure then push the gas and dust particles away from the coma, forming the tail that points away from the sun due to the solar wind's influence. This tail becomes more visible and elongated as the comet gets closer to the sun, making it a sight in night sky.
Therefore, the correct option is (c).
