Answer:
slope of perpendicular line is -1/4
Step-by-step explanation:
slope of standard equation of line that is ax+ by = c is
slope m = -a/b
given equation is
12x – 3y = 81
comparing it with ax+ by = c
a = 12
b = -3
thus
slope of given line = -12/-3 = 4
we also know product of slope of two perpendicular line is -1
let the slope of other line be m
thus,
product of given line line and perpendicular line is -1
4*m = -1
m = -1/4
Thus,
slope of perpendicular line is -1/4
solution for 3/4x - 12 = -18?
Answer:
x = -8
Step-by-step explanation:
Add 12 on both sides
You get 3/4x = -6
Multiply 4/3 on both sides
You get x = -24/3
Simplify and you get -8.
Answer:
x=-8
Step-by-step explanation:
The reason why x is -8 is because
The first step is to isolate the x
To isolate the x you got to add 12 to both sides
[tex]\frac{3}{4}[/tex]x-12+12=-18+12
the -12 gets canceled out by the positive twelve so all thats left now is
[tex]\frac{3}{4}[/tex]x=-18+12,-18+12 is -6 so its [tex]\frac{3}{4}[/tex]x=-6
The second step is to divide
now you have to divide by [tex]\frac{3}{4}[/tex] on both sides
[tex]\frac{\frac{3}{4} x}{\frac{3}4} } =\frac{-6}{\frac{3}{4} }[/tex]
which [tex]\frac{3}{4}[/tex] is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8

you notice a hot air balloon is sending the elevation H in feet of the balloon is modeled by the function h x equals 6X + 90 where X is the time in second since you first noticed the hot air balloon
Answer: you should ask your teacher for help...
Step-by-step explanation:
Answer:
1. 0
2. 0
3. 6
4. 6
5. 90
6. 90
Step-by-step explanation:
x is greater than or equal to 0, and h is greater than or equal to 0, because since it is ascending, it is constantly getting more time, and getting higher up. The slope is 6, so the change of the feet for the hot air balloon is 6 feet per second, and the h- intercept is 90, so the first time you noticed it, is was at 90 feet, so put your points at (0,90) and at (30, 180)

Which describes the slope of the given line?
A. undefined
B. positive
C. zero
D. negative
Answer:
A. underlined
hccuv. huffy. kgigcgi igog if. lnhv
negative, because it is slightly decreasing (going down as it goes right).
Positive would be slanting up
Undefined would be vertical.
Zero would be horizontal.
It has a negative slope.

Five less than three times a number is 1. Find the number
Answer:
n = 2
Step-by-step explanation:
Step 1: Write equation
"Five less" = subtract 5
"three times a number" = 3 × n, or 3n
"is 1" means = 1
3n - 5 = 1
Step 2: Solve for n
Add 5 to both sides: 3n = 6Divide both sides by 3: n = 2Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent? Explain.
Answer:
The equation, y=3 x,
Step-by-step explanation:
y=Distance traveled
x =Total time
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit, and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
Answer:
The equation y = 3x represents a proportional relationship, where y represents distance in miles, and x represents time in hours. The point (3, 9) represents that Alonso walks 9 miles in 3 hours. The point (5, 15) represents that Alonso walks 15 miles in 5 hours.
Point A is located at negative 4 over 6 and point B is located at negative 1 over 6. What is the distance between points A and B?
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals negative 3 over 6 units
negative 4 over 6 minus negative 1 over 6 = negative 3 over 6; therefore, the distance from A to B is absolute value of negative 3 over 6 equals 3 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals 5 over 6 units
negative 4 over 6 plus negative 1 over 6 = negative 5 over 6; therefore, the distance from A to B is absolute value of negative 5 over 6 equals negative 5 over 6 units

True or False: In a ratio table, the ratios are equivalent.
Answer: True
Step-by-step explanation:
a certain map shows two roads. road a is 1 1/4 miles long but is 1 1/2 inches long on the map. what the unit rate for inches per miles on this map? if road b is 10 miles long, how long is road b on the map?
Answer:
30 inches
Step-by-step explanation:
Length of road A = 1¼ miles
Length of road A on map = 1½ inches
Unit rate for inches per miles on the map = 1½ inches ÷ 1¼ miles = ³/2 ÷ ⁵/4 = ³/2 × ⅘ = ⁶/5 inches per mile
Length big Road B on map:
Road B actual length = 10 miles
Thus, using the unit rate of ⁶/5 inches to 1 mile, length of road B on map would be calculated as shown below:
⁶/5 × 10 = 6*5 = 30 inches
Road B is 30 inches long on the map.

Aline has an x-intercept of 3 and a y-intercept of -6.
The slope-intercept form of its equation is
(0,6) & (3,0)
m = (y2-y1)/(x2-x1)
m = (0-6)/(3-0)
m = -6/3
m = -2
Substitute the values in y = mx + c
0 = -2(6) + c
c = 12
Thus, the equation is y = -2x + 12
Answer:
y=2x-6
Step-by-step explanation:
You can plug this into the slope formula, x-intercept of 3 would be (3,0)
and y intercept of -6 would be (0,-6).
Find the slope using the slope formula. The slope is 2
We are given a y-intercept of -6
therefore, the answer is y=2x-6
