There's 1.2 times as much seed, so you can plant 1.2 times more land.
1.2x1=1.2
So you can only plant 1.2 acres.
Answer:
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Step-by-step explanation:
Point B(-6, 1) to B'(-3, -2)
Steps to achieve B"
-6+a= -3 ⇒ a= -3+6= 3
1+b= -2 ⇒ b= -2-1= -3
-----------------
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b): B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
- Step 2 Write two equations: Negative 6 + a = negative 2. 1 + b = negative 3.
- wrong step
Step 3 Solve each equation: Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4 Write the translation rule: (x, y) right-arrow (x + 4, y minus 4)
----------------
- Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
None of them are like terms you have 5a 5b and 4
The linear equation represents y = mx + b describes several real world situations such as
- Relation between printer and ink cartridges,
- Relationship between number of songs and how much is left on the card.
<u>Step-by-step explanation</u>:
Linear equations y = mx + b.
m is your rate of change.
b is your constant. This is the initial value of y. The value of y when x is 0.
Finally, y is the thing that depends on x.
Oh right, examples:
- I buy a printer for $100 and the ink cartridges cost $25 each. The relationship between ink cartridges and total cost.
total cost = 25(cartridges I buy) + 100 or y = 25x + 100
-
I get a $100 iTunes gift card for my birthday and then start buying $1 songs. The relationship between the number of songs I buy and how much is left on the card
amount left on card = -$1(songs bought) + 100 or y = -x +100
