Mara thinks x< 6 will earn the highest score here.
Mamont248 [21]

This question was not correctly written

Correct Question

Mara thinks x ≤ 6 will earn the highest score here.

David thinks x < 6 will.

Who is correct?

Answer:

Mara is correct

Step-by-step explanation:

In the above question, we are given two inequality equations

1) Mara: x ≤ 6

2) David : x < 6

For David , x < 6 means the score which is represented by x is less than 6

For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6

Therefore, Mara is correct because x ≤ 6 will earn the highest score here.

Kristen spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. If she bought a total of 7 then how many of each
Sloan [31]
<span>1 x + 1 y = 7 .............1
Total value
15 x + 28 y = 131 .............2
Eliminate y
multiply (1)by -28
Multiply (2) by 1
-28 x -28 y = -196
15 x + 28 y = 131
Add the two equations

-13 x = -65
/ -13
x = 5
plug value of x in (1)
1 x + 1 y = 7
5 + y = 7
y = 7 -5
y = 2
y = 2
x= 5 plain shirts
y= 2 fancy shirts </span>

Choose the equation that satisfies the data in the table.
pychu [463]

The linear equation that satisfy the data in the table is: A. y = −4x − 4.

<h3>How to Find the Linear Equation for a Data in a Table?</h3>

Given the table attached below, find the slope (m) = change in y / change in x using two pairs of values, say, (-1, 0) and (0, -4):

Slope (m) = (-4 - 0)/(0 - (-1)) = -4/1 = -4

Find the y-intercept (b), which is the value of y when x = 0. From the table, when x = 0, y = -4.

b = -4.

Substitute m = -4 and b = -4 into y = mx + b

y = -4x + (-4)

y = -4x - 4

The equation that satisfy the data is: A. y = −4x − 4.
