Answers:
a) k=11
b) k=10
c) k=-3
d) k=4
e) k=1
I do not mind explaining
For the point (3,k) and virtually every point, 3 is the x coordinate and k is the y coordinate. Therefore, we can substitute 3 for x and solve for k (which is y).
a) 3(3)+2=11
b) 4(3)-2=10
c) 3-2(3)=3-6=-3
d) 3+4=7
e) 3-2(1)=1
Answer:
dont know what the expressions are but imma just guess its doing scientific notation, 8.73 x 10^-11

Answer:
3780 bolts will be made by 8pm
Step-by-step explanation:
One Hour : 500 nuts or 840 bolts
Divide by 2
30 minutes : 250 nuts or 420 bolts
750 nuts : 500 + 250 = 750
so the machine took 1 hour and 30minutes
14:00 it started (2pm)
15:30 it switched to bolts
20:00 (8pm)
4 hours and 30minutes to get to 8pm
<u>840 × 4 = 3360 bolts + 420 bolts = 3780 bolts was made</u>

Answer:
-1.2, -1/5, -.25, 3/4
Step-by-step explanation:
negative numbers are always less than positive.
The greater the negative number, the less it is.
-.25 = -1/4
-1.2, -1/5, -.25, 3/4
