We can easily solve this by assuming a linear equation.
The general form is:
y = m x + b
where y is the price of gas, x is the year, m is the
slope or increase in price every year and b is the y-intercept
We can solve the slope by:
m = (3.25 – 1.75) / (2013 – 2003)
m = 0.15
y = 0.15 x + b
Using any pair data, we get the b:
3.25 = 0.15 (2013) + b
b = -298.7
y = 0.15 x – 298.7
Answer:
4(a-1)(a-2)
Step-by-step explanation:
take out 4 (common factor)
4(a^2-3a+2)
then use box method to factor
<u> a -1</u>
a<u> a^2 -a</u>
<u>-</u>2<u> -2a 2</u>
4(a-1)(a-2)
<em>Solution</em><em>,</em>
<em>7</em><em>x</em><em>-</em><em>1</em><em>4</em><em>=</em><em>2</em><em>x</em><em>+</em><em>1</em><em>1</em>
<em>or,</em><em>7</em><em>x</em><em>-</em><em>2</em><em>x</em><em>=</em><em>1</em><em>1</em><em>+</em><em>1</em><em>4</em>
<em>or,</em><em>5</em><em>x</em><em>=</em><em>2</em><em>5</em>
<em>or,</em><em>X=</em><em>2</em><em>5</em><em>/</em><em>5</em>
<em>X=</em><em>5</em>
<em>The </em><em>answer</em><em> </em><em>is</em><em> </em><em>5</em><em>.</em>

Answer:
a + 12 = -6 , a = -18
Step-by-step explanation:
Hi there!
the first half of the statement says “the *sum* of a number a and 12, so we can write that as a+12. The second half of the statement says that the sum of both of those values is -6, meaning that a + 12 = -6. Knowing this, we can now solve. In order to isolate a, subtract 12 from both sides of the equation. You will be left with a = -18.
Hope this helps!
