Answer:
2.4 weeks
Step-by-step explanation:
So y of Plant A should be equal to y of plant B
1.8x + 3.1 = 2.3x + 1.9
1.8x - 2.3x = 1.9 -3.1
-0.5x = -1.2
x = 2.4
Answer:
(3, -9)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
-5x - 3y = 12
y = x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - 3(x - 12) = 12
- Distribute -3: -5x - 3x + 36 = 12
- Combine like terms: -8x + 36 = 12
- Isolate <em>x</em> term: -8x = -24
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 12
- Substitute in <em>x</em>: y = 3 - 12
- Subtract: y = -9
<u>Step 4: Graph systems</u>
<em>Check the solution set.</em>
-5 because there are 5 points in between those points if it were to be on a graph.
Answer:
To find the slope of a line parallel, you must firs of all make y the subject of the formula i.e
subtract 7x from both side of the equation
which implies : 7x -7x+4y = 5 - 7x
so, 4y = 5 - 7x
Divide both side by 4, since you are to make y to stand alone
This implies y = 5/4 - 7x/4.
Recall: If M1 represent a slope and M2 represent another slope, if they are parallel , then M1 = M2 and if they are perpendicular, then M1 = -1/M2
SO, the slope parallel = -7/4
And the slope perpendicular = -1 divided by -7/4
which implies -1 x -4/7
= 4/7
Step-by-step explanation:
As decimals:
5/30 = 0.166..... (repeating decimal, can be rounded to 0.167)
9/63 = 0.143
As simplified fractions:
5/30 = 1/6
9/63 = 1/7
