Slope formula y2-y1/x2-x1
This makes -4-5/0-3= -9/-3=3.
The slope is 3
Answer:
85-4x<40
12 cars
Step-by-step explanation:
85-4x<40
Solve for x.
-4x<-45
x<11.25
If he build 11 cars, the amount of tires would be over 40, so if he builds<u> 12 </u>cars, it will be below 40.
10(x−2)+15=8x+7
Simplify
10(x−2)+15=8x+7
(10)(x)+(10)(−2)+15=8x+7(Distribute)
10x+−20+15=8x+7
(10x)+(−20+15)=8x+7(Combine Like Terms)
10x+−5=8x+7
10x−5=8x+7
Subtract 8x from both sides.
10x−5−8x=8x+7−8x
2x−5=7
Add 5 to both sides.
2x−5+5=7+5
2x=12
Divide both sides by 2.
2x/2 = 12/2
x=6
Answer:
B and E
Step-by-step explanation:
A: 3 + 6 < 4 + 3 and 6 > 4
9 < 7 is false so A is not the answer.
B: 1 + 5 < 4 + 3 and 5 > 4
6 < 7 and 5 > 4 are true so B is an answer.
C: 2 + (-1) < 4 + 3 and -1 > 4
-1 > 4 is false so C is not an answer.
D: 1 + 1 < 4 + 3 and 1 > 4
1 > 4 is false so D is not an answer.
E: 2 + 8 > 4 + 3 and 8 > 4
10 > 7 and 8 > 4 are both true so E is an answer.
F: -1 + 8 > 4 + 3 and 8 > 4
7 > 7 is false so F is not an answer.
