see explanation
Step-by-step explanation:
Given
f(x) = x² - 6x + 8 and g(x) = x + 2
To solve f(x) = g(x), equate the right sides, that is
x² - 6x + 8 = x + 2 ← subtract x + 2 from both sides
x² - 7x + 6 = 0 ← in standard form
(x - 1)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 6 = 0 ⇒ x = 6
These solutions can be verified from the tables, that is
f(x) = g(x) = 3 ← when x = 1
f(x) = g(x) = 8 ← when x = 6
Answer:
24
Step-by-step explanation:
Basically, for every 5 boys there is 3 girls. A simple way to solve this, but longer, yet the one I personally use count up, go 5*2 3*2 and find which one adds up to 64. Once you get to 64, total including the product of both, you will have the amount of boys and girls. In this case
5*8 and 3*8 = 64
3*8 = 24
5*8 = 40
There are 24 girls
6×+8=14 5×+2=7 14×7=98 ∆m=4.66
Answer:
(3,0)
Step-by-step explanation:
to find the x-intercept, you have to plug in 0 for y to solve for x. this would be -6x-2(0)=-18. this simplifies to -6x=-18. we can divide by -6 on both sides. this results in x=3. this is the value of the x-coordinate, so the answer is (3,0) since the x-intercept is where the line crosses/touches the x-axis.
