What is the largest integer value of n for which 3√ n is less than √ 200? Be sure to explain how you got your answer.
Step-by-step explanation:
[tex]3 \sqrt{n} < \sqrt{200} \\ \sqrt{n} < \sqrt{200} \div 3 \\ \sqrt{n} < \sqrt{200 } \times \sqrt{1 \div 9} \\ \sqrt{n} < \sqrt{200 \times (1 \div 9)} \\ \sqrt{n } < \sqrt{22} \\ n < 22 \\ n = 21[/tex]
200/9=22.22222
so i took the nearest number 22 just to make it easy. I think there is no problem.

3x-2y=-7
2x+5y+=8
Answer: 3x-2y=-7= Slope = 3.000/2.000 = 1.500
x-intercept = -7/3 = -2.33333
y-intercept = 7/2 = 3.50000
2x+5y+=8
Slope = -0.800/2.000 = -0.400
x-intercept = 8/2 = 4
y-intercept = 8/5 = 1.60000
Step-by-step explanation:

Graph the line with the slope of 3/5 and goes through the point (1,2)
Answer:
Here's a screenshot of the correct line:
The line with the slope of 3/5 and goes through the point (1,2) is y = 3/5x + 7/5
The equation of a straight line is given by:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Given the line has a slope of 3/5 and goes through the point (1,2). The equation of the line is given by:
[tex]y-y_1=m(x-x_1)\\\\y-2=\frac{3}{5}(x-1)\\\\y-2=\frac{3}{5}x-\frac{3}{5} \\\\y=\frac{3}{5}x+\frac{7}{5}[/tex]

You have to make a function table.
Candace is visiting a local water park. The table shows information about the number of hours ( input values) and the total cost (output values)
Can anyone help??
(it’s a timed quiz)
Answer:
B. Domain: {1, 3.5, 5, 7.5, 9}
F. Range: {2, 6.50, 7.00, 9.00, 12.50}
Step-by-step explanation:
The set of input values make up the domain of the function, while the corresponding set of output values is the range of the function.
That is, the domain is the number of hours, while total cost is the total cost.
Domain would be: {1, 3.5, 5, 7.5, 9}
Range would be: {2, 6.50, 7.00, 9.00, 12.50}
-8 + k = -17
What is k to make this equation true
Answer: The answer is k= -9
Step-by-step explanation:
this is how you solve it :
-8+k=-17
so then you add 8 to both sides so it would look like
-8+k+8=-17+8
then you simplify
after you simplify it would equal k=-9
THATS ALL :) have a good day
also could you please make me brainleast ???
