–59
–6
Answers
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

x + 3y – 2z = 3
-x – 2y + z = -2
2x – 7y + z = 1
Answers
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
Write an equation of the line that passeg through (8, 1) and is perpendicular to the line 2y + 4x = 12
Answers
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?
Answers
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.

What is m ZSRW?
- 18
- 54
- 126
- 108
Answers
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.
