Answer:
3. domain: {-5, -3, 0, 1, 2}; range: {0, 1, 2, 3}. <u>Is</u> a function.
4. <u>Is no</u>t a function.
Step-by-step explanation:
3. You don't need to list range values twice. Domain and range values are correct otherwise.
The relation is a function, because each domain value is used only once.
__
4. The relation is not a function, because the domain value 4 maps to two different range values. A function can only be single-valued: each domain value maps to exactly one range value.
Answer:
350 Miles
Step-by-step explanation:
140/40 = x/100
x = 350
350 Miles
V = 130 mL
m = 0.250 lb = 113.398 g
Density: d = m/V
d = 113.398 g / 130 mL
d = 0.8722923 g / mL
Answer:
< 4, - 7 >
Step-by-step explanation:
- w - z
= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1
= < 5, - 3 > - < 1, 4 > ← subtract corresponding components
= < 5 - 1, - 3 - 4 >
= < 4, - 7 >
