Write an equation of the line that passeg through (8, 1) and is perpendicular to the line 2y + 4x = 12
Answer:
y=1/2x-3
Step-by-step explanation:
First, let's put the line into slope intercept form
2y+4x=12
subtract 4x from both sides
2y=-4x+12
divide by 2
y=-2x+6
the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:
-2m=-1
divide by -2
m=1/2
so the slope of the perpendicular line is 1/2
here is the new line so far:
y=1/2x+b (b is a place holder)
now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation
1=1/2(8)+b
1=4+b
subtract 4 from both sides
-3=b
so the line is y=1/2x-3
Hope this helps!

A circular "No Parking" road sign has a diameter of 26 inches.
Which measurement is closest to the area of the sign-in square inches?
Answer: The answer is 530.66
Step-by-step explanation:
I took the test and 81.64 is wrong, It's 530.66
The area of the road sign in the circular shape of diameter 26 inches is closest to 530.66 in².
What is the area of a circle?The area of the circle is pi times the square of the radius of a given circle.
The area of the circle = [tex]\pi r^2[/tex]
A road sign "No Parking" is given in a circular shape of diameter 26 inches. we need to find the area of the sign.
The diameter of the circle is 26 in so, the radius will be half of the diameter which will be 13 in.
Now, the area of the circle = [tex]\pi r^2[/tex]
the area of the circle = 3.14 × 13 × 13
= 530.66 in²
Hence, the area of a circle of diameter 26 inches is equal to 530.66 in².

Let f(x) = -2x - 7 and g(x) = -4x + 6. Find (g . f)(-5)
26
3
–59
–6
Answer:
–59
Step-by-step explanation:
f(x) = -2x - 7
f(x) = -2(-4x + 6) - 7
f(x) = 8x - 12- 7
f(x) = 8x - 19
f(x) = 8(-5) - 19
f(x) = -40 - 19
f(x) = -40 - 19
f(x) = - 59

Which of the following is equivalent to tan(5n/6) PLEASE HELP I GIVE EXTRA POINTS AND BRAINLY
Answer:
cot 5^/6
Step-by-step explanation:
The equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship
Tan of a functionThe tan of a function is determined from the ratio of sine of the angle to the ratio of cosine of the angle.
tanθ = sinθ/cosθ
Cot of a functionThis is known as cotangent, which is reciprocal of a tangent.
Cotθ = 1/tanθ = cosθ/sinθ
Thus, the equivalent expression for tan(5π/6) will be cot(5π/6) based on the above relationship

x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1
Answer:
x + 3y – 2z = 8
-x – 2y + z = 12
2x – 7y + z =7
this answer is fake
Step-by-step explanation:
x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1

1( you take ED and the 5 and say of 5.
2( then you count all the letters that stand for numbers and count them.
3) after you count them how many ever there are then you take that number which was 5 too.
4(after you find that number which is number 5 you multipliy 5 and 5.

What is m ZSRW?
- 18
- 54
- 126
- 108
Answer:
126
Step-by-step explanation:
Angle SRW is supplementary to (2x + 18)º and (3x)º, that is, they add up to 180º.
Finding angles in function of X:
Since angles (2x + 18)º and (3x)º are opposite by vertex R, they have the same measure. So
[tex]3x = 2x + 18[/tex]
[tex]x = 18[/tex]
So
[tex]3x = 3(18) = 54[/tex]
Angle SRW:
Supplementary with 54. So
54 + SRW = 180
SRW = 180 - 54 = 126
So 126 is the answer.
