Step-by-step explanation:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height.
So . .
- 2 × 1 × 1
= 4.5 or 4
Answer:
{-9.5, 1,7}
Step-by-step explanation:
For y =f(x)
domain is list of all values of x and range is list of all values of y
Given
ƒ(x) = 3x – 5
domain = {–1.5, 2, 4}.
thus,
range will be value of f(x)
when x = -1.5
x = 2 and x = 4
Thus,
for x = -1.5
ƒ(x) = 3*-1.5 – 5 = -4.5 - 5 = -9.5
\
for x = 2
ƒ(x) = 3*2– 5 = 6 - 5 = 1
for x = 4
ƒ(x) = 3*4– 5 = 12 - 5 = 7
thus,
range of ƒ(x) = 3x – 5 is {-9.5, 1,7}
Answer:
Step-by-step explanation:
y - 3 = (-1/2)(x - 2)
Solve 8x-4y+9=0 for y so as to find the slope of this given line:
8x + 9 = 4y, or y = 2x + 9/4. The slope of the given line is 2. The slope of any line perpendicular to this one is the negative reciprocal of 2, which is -1/2.
Use the point-slope formula: y - k = m(x - h ). (h, k) is (2, 3) and m is -1/2.
Then we have: y - 3 = (-1/2)(x - 2)
