To start, we need to distribute
multiply 2x by <em>everything</em> in the parenthesis
2x (5 + 3x) - x
2x × 5 = 10x
2x × 3x = 6x²
now we have...
10x + 6x² - x
<em>simplify </em>
<u>6x² + 9x </u>
the coefficient of x is 9!
When finding slope the answer is always going to be rise/run so in this case,
#1 would be 1/2 (bc it goes up one and right 2)
#2 we have a rise of 3 and a run of 3 leaving our slope to be 3/3 simplified simply being 1
another trick you could use is dividing the denominator by the numerator
Answer:
1. Slope = 42.667/2.000 = 21.333
2. x-intercept = 6/64 = 3/32 = 0.09375
3. y-intercept = 6/-3 = 2/-1 = -2.00000

Answer:
g(r) = 18
Step-by-step explanation:
Substitute 10 into r
g(10) = 2( (10) -1)
= 2(9)
= 18
