Answer:
x = 1/3
Step-by-step explanation:
-12x + 12 = 4 - 15x + 9
Combine like terms
-12x +12 = -15x+13
Add 15x to each side
-12x+12 +15x = -15x+15x+13
3x+12 = 13
Subtract 12 from each side
3x+12-12 = 13-12
3x = 1
Divide by 3
3x/3 = 1/3
x = 1/3
To practice, what if the two are added now? lets add one term at a time. first the x terms. 3x+x= 4x. then y+-3y=-2y. finally 3+-2=1. now putting them together we get 4x-2y=1.
multiplying the first equation by 3 gets us 9x+3y=9. basically multiplying each term by 3. now just do the same thing from the first part, so start with the new 9x+x and continue
The answer is 9.2
If you want simplest form as a fraction it would be 9 1/5
X = principle ( 1 + rate/compound rate) ^ years
x = 4250[1+(0.3/4)]^12
x = 4250(1+0.075)^12
x = 4250(1.075)^12
x = 4250(2.38178)
x = $10,122.23
Answer:
y = 5
General Formulas and Concepts:
<u>Alg I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
Step-by-step explanation:
<u>Step 1: Define variables</u>
Point (-2, 5)
Slope <em>m</em> = 0
<u>Step 2: Write function</u>
y - 5 = 0(x + 2)
y - 5 = 0
y = 5
<u>Step 3: Identify</u>
y = 5 is a horizontal line.
