I don't exactly know how to explain step 2 but the working is:
5 - 8x < 2x + 3
5 - 3 < 2x + 8x
2 < 10x
5 < x
(I'm sorry if it's wrong)
Answer:
the answer is D
Step-by-step explanation:
5x+6=16
-6 -6
5x=10
divide both sides by five
x=2
Vertex point: (1, -4)
X-intercepts: (-1, 0) , (3, 0)
Y-intercept: (0, -3)
Axis of symmetry: x = 1
This function will create a parabola that opens upwards. I’m not entirely sure what I was supposed to answer. Hopefully this covered it. I’ll attach an image of the parabola in case I missed anything.
Answer:
24
Step-by-step explanation:
(-4) -6? well it equals 24 because a negative plus a negative equals a positive.
Hope my answer has helped you! If not i'm sorry.
The value of f(-3) for the function f(a) = -2a² - 5a + 4 is 1.
<h3>What are functions?</h3>
Function relates input and outputs. The outputs are called the ranges of dependent variables while the input are called domain or independent variables.
Therefore,
f(a) = -2a² - 5a + 4
Hence,
f(-3) = -2(-3)² - 5(-3) + 4
Therefore,
f(-3) = -18 + 15 + 4
f(-3) = -3 + 4
f(-3) = 1
