Write the equation of a line that passes
through (-3,-8) and (3, 10).
Answer:
y=3x+1
Step-by-step explanation:
The equation will most likely be in slope-intercept form which is
y=mx+b
(m) is the slope,
(b) is the y intercept
First we must find the slope. The formula for slope is (y1-y2)/(x1-x2)
Which means we take the (y) of the second given point and subtract the (y) if the first given point, then divide that by the (x) of the second given point minus the (x) of the first given point.
(10-(-8)/3-(-3)
18/6
Simplify
3/1
3, our slope is 3.
Now we can put this into our formula
y=3x+b
To find the y intercept we just apply one of the given points. (I'll use (3, 10) but either of them would work.
10=3(3)+b
Now solve
10=9+b
Subtract 9 from each side
1=b
Now we put our slope and y intercept into our formula
y=3x+1.
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

What is the measure of angle x
Answer:
X=67
Step-by-step explanation:
The angles of a triangle adds to 180
So x is 180-46-67=67
Answer:
21
Step-by-step explanation:
∠AHI + 67° = 180° (corresponding angles are equal)
∠AHI = 180° - 67°
∠AHI = 113°
x + ∠AHI + 46° = 180° (angle sum property of a triangle)
x + 113° + 46° = 180°
x + 159° = 180°
x = 180° - 159°
x = 21°
hope it helps you!

A parking garage at the airport charges $20.00 for the first day. Each additional day after the first day costs $8.00 more. So parking for 2 days costs $28.00,
parking for 3 days costs $36.00, parking for 4 days costs $44.00, etc. How much will it cost to park a car in the garage for 21 days?
Answer:
Step-by-step explanation:
20+8x=cost
20+8(21)=cost
188 is your cost after 21 days
Susan’s science class is performing an experiment that involves dropping objects from various heights, starting close to the ground and working upward to 8 feet. The function , where x represents the distance from the ground, represents the time it takes for the object Susan drops to hit the ground. The graph represents the function
Identify some of the key features of the graph. That is, determine if the function is monotonically increasing or decreasing, state the end behavior, find the x- and y-intercepts, find the endpoint, and state the domain and the range of the graph (without considering the context).
Answer:
1) The function is monotonically increasing
2) The end behavior of the function is x tends to infinity as t(x) tends infinity
3) The x and y -intercept is (0, 0)
4) The endpoint is (0, 0)
5) The domain is 0 ≤ x ≤ +∞
The range is 0 ≤ t(x) ≤ +∞
Step-by-step explanation:
1) The given function of the time for the object to hit the ground is t(x) = 1/4·√x
Where;
x = The distance from the ground
t = The time it takes for the object to hit the ground
Monotonically increasing function, we have;
A function that is continuous on [a, b] and it can be differentiated in the domain, (a, b) is monotonically increasing when df(x)/dx > 0 for all values of x in (a, b)
However, where df(x)/dx < 0 for all values of x in (a, b), the function is decreasing
Therefore, using an online tool, we have;
dt(x)/dx = d(1/4·√x)/dx = 1/8 × 1/√x
Therefore, the dt(x)/dx > 0, for 0 < x < +∞ and the function is monotonically increasing
2) The end behavior of the function as x tends to infinity, t(x) = 1/4·√x approaches infinity
3) From the end behavior, and the nature, of the function t(x) = 1/4·√x, where both variables are directly proportional, we have that the x and y -intercept = (0, 0)
4) The endpoint is (0, 0) given that as t(x) tends to 0, x tends to 0
5) The domain is 0 ≤ x ≤ +∞
The range is 0 ≤ t(x) ≤ +∞.
Answer:
The function is monotonically increasing since the output values are continually getting larger. This also tells us that the end behavior of the function is infinity.
The x-intercept is (0,0), the y-intercept is (0,0), and the endpoint too is (0,0).
The domain of the graph is all values greater than or equal to 0, and the range is all positive output values.

What % of 440 is 286?
Answer:
65
Step-by-step explanation:
Hope it helps!!!
Answer:
286 is 65 % of 440
Step-by-step explanation:
line up your numbers with your procentage and cross multiply:
440 represents 100%
286 represents ? %
? *440=286 *100 divide both sides by 440
?= 286*100/440=65

Step-by-step explanation:
use the graph and table to write the equation that describes the line graph
Answer:
y = x + 3 or y = 1x + 3
Step-by-step explanation:
Since we're just going to find the equation (assuming it's slope-intercept form, which is y = mx + b), our jobs will be relatively simple!
Let's start with the first step and identify the y-intercept, which is the easiest step.
That will be (0,3), as the line intercepts the y-axis there.
Next, let's find the slope of the line using [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{2}-{y}_{1}}{x_{2}-{x}_{1}}[/tex]. Just be careful when using [tex]\frac{rise}{run}[/tex] that you correctly identify the scale the axis' are using.
For now, I'll use [tex]\frac{y_{2}-{y}_{1}}{x_{2}-{x}_{1}}[/tex]. Let's pick two points... (0,3) and (1,4).
—> [tex]\frac{4-3}{1-0}[/tex] = [tex]\frac{1}{1}[/tex]
This will be our slope, 1.
We now have our answer, y = 1x + 3.
