By creating a common denominator for all of the fraction (12) the answer would be 7 3/12 or 7 1/4
Use the substitution method
Answers :
g(x)= -3x+1
a. g(10)= -3(10)+1
Mutiply first = -30
-30+1= -29
<em>g(10)= -29</em>
b. g(-2)= -3(-2)+1
Negative sign and negative sign = positive sign
-3(-2)= 6
6+1= 7
<em>g(-2)= 7</em>
a.
f(x)=x^2+7
f(3)= 3^ 2+7
3*3 because of the exponent. 3*3= 9
9+7= 16
<em>f(3)= 16</em>
d.
f(a)= a^2+7
a*a= a^2
a^2+7
<em>f(a)= a^2+7</em>
Answer: Choice D) Slopes are the same
----------------------------------------
Explanation:
The graph of f(x) is a straight line through the two points (0,3) and (1,1). Those points are the left and right points respectively.
Start at (0,3). To get to (0,1), we move 2 units down and 1 unit to the right. Think of the "2 units down" as a "rise of -2". Negative rise means you're really falling.
So the slope of f(x) is
slope = rise/run = -2/1 = -2
slope = -2
The slope of g(x) is also -2
Note how y = -2x-5 is in y = mx+b form
we see that m = -2 is the slope
b = -5 is the y intercept
So that shows why the two functions have the same slope.
Answer: We will see in the next example how using the Quadratic Formula to solve an equation with a perfect square also gives just one solution. Solve 4{x}^{2}-20x=-25
