Answer:
y = 250x + 1500
Step-by-step explanation:
y = mx + b
y = 3000
m = 250
x = 6
3000 = 250(6) + b
Multiply.
3000 = 1500 + b
Subtract.
1500 = b

Step-by-step explanation:
James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales that week?
Answer:
His sales that week were $2,160.
Step-by-step explanation:
First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:
$432-$324=$108
Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:
5% → 108
100% → x
x=(100*108)/5=2160
According to this, the answer is that his sales that week were $2,160.

Which function is linear?
Answer:
Its D
Step-by-step explanation:
The word linear is used for a straight line. A linear function is a function of a straight line, which means that the degree of a linear function must be 00 or 11. In this case, The degree of f(x)=x5−10f(x)=x5-10 is 11, which makes the function a linear function.
f(x)=x5−10f(x)=x5-10 is a linear function
A bike costs $350. It is on sale for 35% off.
What is the sale price of the bike?
Answer:
$227.50
Step-by-step explanation:
35% of $350 = 0.35 x 350 = $122.5
This is the amount that is reduced (subtracted) from the original price of $350.
The sale price is: $350 - $122.5 = $227.50

Martin is not correct.
Calculating TemperatureFrom the question, we are to determine the afternoon temperature in Westfield City
From the given information,
"In the morning, the temperature in Westfield City was -2°F"
and
"By afternoon, a north wind caused the temperature to drop another 8°F"
Thus,
The afternoon temperature = -2°F - 8°F

The equation of a straight line is y = 20 – X.
If the x value of a point on the line is 14, what is the y value of this point?
Given:
The equation of a straight line is
[tex]y=20-x[/tex]
The x value of a point on the line is 14.
To find:
The y value of this point.
Solution:
If a point (x,y) lines on line, then the equation of line must be stratified by that point.
We have, the equation of a straight line.
[tex]y=20-x[/tex]
Putting x=14, we get
[tex]y=20-14[/tex]
[tex]y=6[/tex]
Therefore, the y-value is 6 when the x-value is 14.

Step-by-step explanation:
Given that,
Mya has 3 times as much floor as Eric. Mya has 15.81 lb of floor. The relation is given by :
Let Eric has F floor.
3F = 15.81 ...(1)
We need to find how much flour Eric has.
Dividing both sides by 15.81.
F = 15.81/3
F = 5.27 lb
Hence, Eric has 5.27 lb of flour.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term.
Answer:
0.527
Step-by-step explanation:
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term
The sequence given in the above Question is a geometric sequence.
The formula for the nth term of a geometric sequence is given as:
an = a × r ^n - 1
Where
a = First term
r = Common ratio
n = nth term
From the above question, we are asked to find the 7th term
Hence:
a = 6
Common ratio = Second term/first term
= 4/6 = 2/3
n = 7
The 7th term = 6 × (2/3 )^7 - 1
= 6 × (2/3)^6
= 6 × (2/3)⁶
= 0.5267489712
Approximately to the nearest thousandths the 7th term = 0.527
