What whole number best approximates the value of x?
ivanzaharov [21]

The answer is 87

For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4

the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up

Hope this helps :)

Graph the line with slope 1/4 and y-intercept -8
kherson [118]

Solution: Below! ^^

Detailed explanation:

Hii! I'm sorry, I can't graph the line for you, but I'll try to give you the best possible explanation.

First, note that the question provides us with the info that the y intercept is -8. This is a very valuable piece of information!

This means that the line crosses the y axis (since it's the y intercept) at the point (0,-8). Plot it on the co-ordinate plane.

Next, this question also provides us with the fact that the slope of the line is 1/4. This is yet another valuable piece of information!

What this tells us is: from that point (0,-8), you need to go up 1 unit, then over 4, and so forth, until you obtain a line.

_________

Hope I helped, best wishes & happy studies!

Please reach out to me if any queries arise.

What is the y and x intercept for f(x)=3x-2 find f(-5)​
masya89 [10]

Answer:  The y- intercept is -2.  The x-intercept is 2/3

The attachment shows the solutions.

Step-by-step explanation:  The y-intercept is the "b" term in the slope-intercept form of the equation. To find the x-intercept, substitute 0 for the output and solve for x.

0 = 3x -2 . Add 2 to both sides

2 = 3x . Divide both sides by 3

2/3 = x   the x-intercept is 2/3

To find f(-5) substitute -5 for x and solve.

f(-5) = 3(-5) -2

f(-5) = -15 -2

f(-5) = -17

Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?
Nastasia [14]

Answer:

d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }

Step-by-step explanation:

The distance formula is d= \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}     }.

6 is x_{2}, 9 is x_{1}, 3 is y_{2}, and -2 is y_{1}.

When you plug these into the formula, you get d = \sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }
