The wording of the second function may be interpreted in several differente ways. These are some:
g(x) = (x^2 +2)(x-8)
g(x)=x^2 + 2(x-8)
g(x) x^2 +2x - 8
I will work with the last one, so my system of equation is:
f(x) = - x +2.5
g(x) = x^2 + 2x - 8
f(x) = g(x) ⇒ - x + 2.5 = x^2 + 2x - 8
x^2 + 3x - 8 - x - 2.5 = 0
x^2 + 3x - 10.5 = 0
Use the quadratic formula to solve for x:
x = [ - 3 +/- √(3^2) - 4(1)(-10.5) ]/2
x = - 5.07 and x = 2.07
Answer:
-3+6y = 9x
6y = 9x+3
y = 9/6x+3/6
y = 3/2x+1/2 ⇒ slope-intercept form
Answer:
13x + 14
Step-by-step explanation:
5x + 6 + 3x = 8x + 6.
8x + 6 + x + 1 + x + 1 + 2= 10x + 10
10x + 10 + (2²)(i think) = 10x + 14
10x + 14 + 3x = 13x + 14
final answer
Answer:
Step-by-step explanation:
Use the following equation the find the slope:
Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope". Insert the known values:
Solve:
Simplify. Two negatives make a positive:
Simplify fraction by dividing top and bottom by 5:
The slope is 3.
:Done
In part A, if a's value is 1 then b is 2 and so on so the first letter of your name will have a number, and for part b you tale 3 letters that make up a word and the number after also equals 20.
