1) 8 + 4 = -5 + 7
12 = 2
FALSE
2) y = -11x + 4
(0, -7): -7 = -11(0) + 4 ⇒ -7 = 0 + 4 ⇒ -7 = 4 False
(-1, -7): -7 = -11(-1) + 4 ⇒ -7 = 11 + 4 ⇒ -7 = 15 False
(1, -7): -7 = -11(1) + 4 ⇒ -7 = -11 + 4 ⇒ -7 = -7 True
(2, 26): 26 = -11(2) + 4 ⇒ 26 = -22 + 4 ⇒ 26 = -18 False
Answer: C
3) Input Output
0 0
<u> 1 </u> 3
2 <u> 6 </u>
3 9
<u> 4 </u> <u> 12 </u>
5 15
6 <u> 18 </u>
Rule: input is being added by 1, output is 3 times x
4) c = 65h
5) 2x = -6
x = -3
6) 8j - 5 + j = 67
9j - 5 = 67 <em>added like terms (8j + j)</em>
<u> +5</u> <u>+5 </u>
9j = 72
j = 8
7) y = mx + b
<u> -b</u> <u> -b </u>
y - b = mx
I think it’s even because if you flip one of them they will equal up on the same line. it’s basically the inverse of the other one so it’s even
Answer:
6 13/30 1 9/10 2 8/15 2 37/40 miles in 2 days 1/4<3/10 5/6>7/10 23/24
Step-by-step explanation:
<h2>
<u>22 minutes 44 seconds</u></h2>
Step-by-step explanation:
1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min
2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min
Together Time taken = <em>n</em> min/job ; invert to get rate = 1/<em>n</em> job/min
------------------
Equation :-
Rate + Rate = together rate
1/65 + 1/35 = 1/n
-----------------------------
35<em>n</em> + 65<em>n</em> = 35*65
-----------------
100<em>n</em> = 2275
<em>n</em> = 22.75 minutes = <u>22 </u><u>minutes</u><u> 45 </u><u>seconds</u>
