Answer:
296 and 22
Step-by-step explanation:
111/6 = 18.5 according to the chart given, so
x/16 = 18.5.
Multiply both sides by 16 to isolate x.
x = 296
check work:
296/16 = 18.5
do the same to 407:
407/x = 18.5
Mulitply both sides by x.
407 = 18.5x
divide both sides by 18.5 to isolate x.
22 = x
check work:
407/22 = 18.5
Answer:
Image #1) x=0
Image #2) y= 4
x= 4
y= x
y= -x+8
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Inequalities of the type | x | ≤ a, have solution of the form
- a ≤ x ≤ a , so
| x | ≤ 4
- 4 ≤ x ≤ 4
The values of x are between - 4 and + 4, but can equal - 4 and 4 since the symbol is ' less than or equal to '
This is indicated on a number line by solid circles, where not equal to are denoted by open circles.
Thus the solution is Graph B
Answer:
After 7 seconds it hits the ground.
h= -16^2 + 80x + 224
(I'm assuming this is what you meant, because these problems are generally quadratic)
Use quadratic formula to find when it hits the ground (get zeros)
x = -2, x = 7
After 7 seconds it hits the ground.
