Answer: y = 2/1 x 0
Step-by-step explanation:
Y=mx+b
2 and 1 are the “rise and run” (m) (from one point to the next, you must go up 2 units then right 1 unit)
The y intercept (b) is the point where it is on the y axis but 0 on the x axis, so 0
Answer:
The correct option is;
B. Use a formula
Step-by-step explanation:
Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;
1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA
2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²
3) The amount of paint needed, AmP is therefore given by the following formula
AmP = A × AU = 135 × AU
Answer:
1 : 2
Step-by-step explanation:
Given that,
amount of coloured fabric Gordon use to make his curtain = 24mm
amount of white fabric Gordon use to make his curtain = 1.2cm
To find,
ratio of the amount of white fabric to coloured fabric
1 cm = 10mm
1.2 cm = 1.2 * 10
= 12 mm
<h3>Ratio</h3>
12 / 24
1 / 2
1 : 2
So, ratio of the amount of white fabric to coloured fabric is 1 : 2
Answer:
subtraction & multiplication
Step-by-step explanation:
Answer: x=-1, y=2, z=-3
Step-by-step explanation:
[1] 2x + 3y - 4z = 16
[2] -x + 2y - z = 8
[3] 2x - y - 2z = 2
Solve by Substitution :
Solve equation [3] for the variable y
[3] y = 2x - 2z - 2
Plug this in for variable y in equation [1]
2x + 3•(2x-2z-2) - 4z = 16
8x - 10z = 22
Plug this in for variable y in equation [2]
-x + 2•(2x-2z-2) - z = 8
3x - 5z = 12
Solve equation [2] for the variable x
3x = 5z + 12
x = 5z/3 + 4
Plug this in for variable x in equation [1]
8•(5z/3+4) - 10z = 22
10z/3 = -10
10z = -30
Solve equation for the variable z
10z = - 30
z = - 3
By now we know this much :
x = 5z/3+4
y = 2x-2z-2
z = -3
Use the z value to solve for x
x = (5/3)(-3)+4 = -1
Use the x and z values to solve for y
y = 2(-1)-2(-3)-2 = 2
