Which of the following equations is true for all values in Guthrie's input-output table?
AI +3 = y
B :+7=y
C 3x+1=y
D) 4.1 - 1=y
9514 1404 393
Answer:
C 3x +1 = y
Step-by-step explanation:
x-values increase by 1 from row to row.
y-values increase by 3 from row to row.
The slope of the linear function is the ratio of the y-increase to the x-increase:
m = ∆y/∆x = 3/1 = 3
The only offered choice with an x-coefficient of 3 is ...
C 3x +1 = y
__
If you check this against the table entries, you find it fits.
3(1) +1 = 4
3(2) +1 = 7
and so on.

Step-by-step explanation:
Answer: 10
Step-by-step explanation: 7x-11=x-49
7x - 11 = x - 49 so add 11 to both sides 7x = x -60
Then 7x - x = 6 so 60/6= 10

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone. He heard a crack, but luckily it wasn't his iPhone 11. It was his spinal cord.
Compare the price between the iPhone 11 and spinal cord repairence.
(This question was on a question in math and it's kinda funny XD)
Answer:
The difference between iPhone 11 and Spinal cord repairence is 99,300$.
Step-by-step explanation:
To be honest, this is a really weird question. But a spinal cord injury can cost up to 100,000$ a year. And an iPhone 11 cost around 700$. It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol. And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.
Suppose the ratio of girls to boys in your school is 19:17. There are 1908 students altogether. Write and solve a system of equations to find the total number of boys and girls in the school.
Answer:
901 boys and 1007 girls
Step-by-step explanation:
let b be the number of boys
let g be the number of girls
[tex]b + g = 1908\\17g = 19b\\g = \frac{19}{17} b\\b+\frac{19}{17} b = 1908\\2\frac{2}{17}b = 1908\\b = 901\\901 + g = 1908\\g = 1007[/tex]

N 1846 the depth of the river was 5 feet deep. In 1847 it dropped to 3.2 feet. This year, 1848, it rose to 6.6 feet. Find the percent change in river depth
Answer:
40.4%
Step-by-step explanation:
Given data
Initial depth= 5feet
Final depth= 5-3.2+6.6= 8.4feet
Hence the percent change
% change= FInal-initial/final*100
% change= 8.4-5/8.4*100
% change= 3.4/8.4*100
% change= 0.404*100
% change=40.4%
Hence the percent change is 40.4%
Percentage change between two measurement is the proportion of
change between the measurement expressed as a percentage.
The percentage change in the river depth in in 1848 is 106.25%
Reasons:
The given parameters are;
The depth of the river in the year 1846 = 5 feet
In the year 1847, the depth = 3.2 feet
In 1848 the depth = 6.6 feet
[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]
Which gives;
[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]
The percentage change in the river depth in the current period = 106.25%

Determine the slope of the line that passes through each pair of points. Write in simplest form. (3,8) and (1,5)
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.
