<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❎

 For Cora's recipe the rate is:
 r2 = 2.4 / 8
 r2 = 0.3
 The difference between both recipes is:
 r1-r2 = 0.35 - 0.3 = 0.05
 Answer:

What is the location of the point on the number line that is 3/7 of the way from A=6 to B=20?
-Dominant- [34]

Answer:

12

Step-by-step explanation:

20-6=14 (Distance between points) then 14*3/7=6.

3/7 of the distance from A=6 to B=20 is 6. Thus, we find the point that is

3/7 of the distance from A=6 to B=20 by adding 6 to 6.

6+6= 12

Therefore, the point that is

3/7 from A=6 to B=20 is 12.

= 01:20

So your answer is:

01:35 which is 1 hr, 35 mins.

Which two equations below could you solve to find D, the number of days it takes the water lily population to double? 2 = 3.915(
EastWind [94]
This is the concept of algebra, suppose the initial number was x, and the new number is 2x. The constant rate of growth is r and time is D, the function representing growth will be given by:
2x=x(r)D
from our choices the equations that represents the information above will be:
7.830=3.915(1.106)D
and
7.830=3.915(2)D
this is because from both equations we see the initial number was 3.915 and doubled to 7.830
