Answer:
Step-by-step explanation:
i) 1
ii) see attached
iii) as x goes from 0 to 2, y decreases parabolically from 1 to an acme at -3
iv) y = (x - 2)² - 3
v) -3 < t < 1
if t < -3 no intersection occurs between y = t and y = (x - 2)² - 3
if t = -3, y = t intersects the curve at only one point, (2, -3)
if -3 < t < 1 there exist two intersecting points with positive x values
if t = 1 there exist only one positive x value intersection as the other is at (0, 1) and 0 is neither positive nor negative.
if t > 1 there is one positive x value intersection and one negative x value intersection.
Answer:
x=8
Step-by-step explanation:
4x+7=6x-9
subtract 4x to 6x
7=2x-9
add 9 to 7
16=2x
divide 2 to 16
x=8
Hope this Helped you☺♥
Answer: D
Step-by-step explanation:
The numeric values for the function are given as follows:
a) f(-5) = 14.
b) f(0) = 10.
c) f(5/2) = 8.
d) f(5a) = -4a + 10.
e) f(5a - 15) = -4a + 22.
<h3>How to find the numeric value of a function?</h3>
To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the function is given by:
f(x) = -0.8x + 10.
Hence the numeric values are given as follows:
- f(-5) = -0.8(-5) + 10 = 14.
- f(0) = -0.8(0) + 10 = 10.
- f(5/2) = f(2.5) = -0.8(2.5) + 10 = 8.
- f(5a) = -0.8(5a) + 10 = -4a + 10.
- f(5a - 15) = -0.8(5a - 15) + 10 = -4a + 22.
