Answer:
6
Step-by-step explanation:
The line is written in slope-intercept form, which is y=mx+b.
mx represents the slope and b represents the y-intercept.
Here is the question again
Answer:
[tex]\huge\boxed{11}[/tex]

Step-by-step explanation:
A horticulturist wants to improve the soil quality in a garden by adding 120 pounds of nitrogen and 54 pounds of potassium. A pack of organic fertilizer contains 2 pounds of nitrogen and 3 pounds of potassium, and a pack of inorganic fertilizer contains 6 pounds of nitrogen and 2 pounds of potassium. How many packs of each type of fertilizer does the horticulturalist need to use? (Hint Write an equation for the total amount of nitrogen (120 pounds) obtained by adding the packs of both the fertilizers and another equation for the total amount of potassium (54 pounds) obtained by adding the packs of both the fertilizers.)
A organic fertilizer: 24 packs; inorganic fertilizer: 12 packs
B. organic fertilizer: 14 packs; inorganic fertilizer: 6 packs
C organic fertilizer: 15 packs; inorganic fertilizer: 8 packs
D. organic fertilizer: 9 packs; inorganic fertilizer: 17 packs
Е. organic fertilizer: 6 packs; inorganic fertilizer: 18 packs
x and y are the packs of organic and inorganic fertilizer, respectively.
pounds of nitrogen added = 2x + 6y = 120
pounds of potassium added = 3x + 2y = 54
eliminate the y terms. subtract the first equation from 3 times the second equation.
9x + 6y = 162
-2x - 6y = -120
------------------
7x = 42
x = 6
y = 18

-5/6m = -60
m = ?
Step-by-step explanation:
Hey there!
Given;
-5/6m = -60
~ Multiply "6m" and "-60".
-5 = 6m*-60
-5 = -360m
~ Divide "-5" by "-360"
m = -5/-360
m = 1/72
Therefore, the value of "m" is 1/72.
Hope it helps....

Line BC is represented by 3x + 2y = 8. Line AD is represented by –3x – 2y = 6. What is the relationship of line BC to line AD? Explain how the sum of the equations demonstrates this relationship.
Answer:
2
Step-by-step explanation:
if you suntract the 2 you, 3x cancels 2y cancels, 8-6 is 2
Answer: Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

$22 haircut; 20% tip
help..
Answer:
20% tip = $4.40; total = $26.4
Step-by-step explanation:
20 % = 0.20 ------> 22 * 0.20 = 20% of 22
20% of $22.00 = $4.40
total = $22.00 + $4.40
total = $26.40

Calculate the slope by picking two points from the table and using the slow formula
What is the slope of the table? SHOW WORK
Circle the Y intercept on the table what is the Y intercept
i need help with this asap!!
Answer:
perimeter you add all sides together:
5x+2 +5x+2 +x +8 +x+8
12x +20
and for Area you multiply:
(x + 8)(5x + 2)
5x^2 + 2x + 40x +16
5x^2 +42x +16
so your answer is the first one or "A"

Answer:
Equation of the Line: y = 1.25x + 5
Equation in Standard Form: 5x - 4y = -20
Step-by-step explanation:
y = mx + b
[tex]\frac{17.5 - 22.5}{10 - 14}[/tex] = [tex]\frac{-5}{-4}[/tex] = [tex]\frac{5}{4}[/tex] or 1.25
y = 1.25x + 5
Ax + By = C (A must be positive, and no fractions or decimals)
y = 1.25x + 5
-1.25x + y = 5
times -4
5x - 4y = -20

I’m doing a percent equation and I need help please here is the question 80% of blank = 52
Identify the slope (m) and y-intercept (b) of each linear equation.
52. 3x+4y=24
Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}
Tony hangs lights in his back yard. The rule c=14f gives the number of lights, c, there are for each foot, f, of wire. How many lights are on 8 feet of wire?
Answer:
112 lights
Step-by-step explanation:
The rule c=14f gives the number of lights, c, there are for each foot, f, of wire.
We need to find the number of light on 8 feet of wire.
Put f = 8 in the given rule equation
c = 14 × 8
= 112
Hence, there are 112 lights on 8 feet of wire.
