Explanation, I have a 128% in math rn…
<h3>1. Which ordered pair is a solution of the equation y = x - 4?</h3>
[ Option A ]
(2,6)
y = x - 4
6 = 2 - 4
6 = -2 ❎
[ Option B]
(6,2)
y = x - 4
2 = 6 - 4
2 = 2 ✔️
[Option C ]
(-2,6)
y = x - 4
6 = -2 - 4
6 = -6 ❎
[ Option D ]
(-6,2)
y = x - 4
2 = -6 - 4
3 = -10 ❎
<h3>2. Which value is a solution of the equation 3 - 2x = -5?</h3>
A. 2
B. 4✔️
C. -2
D. 1/5
<u>Step by step explanation :</u>
3 - 2x = -5
3 + 5 = 2x
8 = 2x
8/2 = x
<u>4 = </u><u>x</u>
<h3>3. Which ordered pair is a solution of the equation y = 5x?</h3>
A. (-2,10)
B. (-5,25)
C. (-3,15)
D. (-2,-10)✔️
<u>Step by step explanation :</u>
y = 5x
y/x = 5
(-10)/(-2) = 5
<h3>4. Which ordered pair is a solution of the equation y = -9x + 4?</h3>
A. (10,-86)
y = -9x + 4
-86 = -9(10) + 4
-86 = -90 + 4
-86 = -86 ✔️
B. (-4,-58)
y = -9x + 4
-58 = -9(-4) + 4
-58 = 36 + 4
-58 = 40 ❎
C. (6,-41)
y = -9x + 4
-41 = -9(6) + 4
-41 = -54 + 4
-41 = -50 ❎
D. (-6,57)
y = -9x + 4
-57 = -9(-6) + 4
-57 = 54 + 4
-57 = 58❎

Answer:
The answer is 2
Step-by-step explanation:
3/4÷ 3/8 =
3 × 8 * 4 × 3 =
24/12 =
<u>24 ÷ 12</u>
12 ÷ 12 = 2
(5/8)*10lbs = 6.25 lbs
(2/5)*10lbs = 4 lbs
(3/4)*10lbs = 7.5 lbs
then add and convert to ounces.
ignore my reply it is wrong.
Answer:
C
Step-by-step explanation:
If this was an equation...
(x-3)(x+5) = 0
x = 3, -5
So 3 and -5 are the minimum and the maximums.
So we convert that into an inequality.
-5 <= x <= 3
Answer:
She has 607 nickels
Step-by-step explanation:
40 x 15 + 7 = 607
F [g(x)]
= 5(6x) - 1
= 30x - 1
g [f(x)]
= 6(5x - 1)
= 30x - 6
g [f (2)]
= 6 [5(2) - 1]
= 6 (10 - 1)
= 60 - 6
=54
