Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2
4x + 92 ≥ 200
the $92 are regardless and you make $4 every sale (x) to solve this you would multiply the number of sales (x) by 4 then add the initial 92
Let's assume
boiling point is y
altitude is x
we are given
This relationship between altitude and boiling point is linear
At an altitude of 1000 feet, water boils at 210°F
so, first point is (1000,210)
so, x1=1000 , y1=210
At an altitude of 3000 feet, water boils at 206°F
so, second point is (3000,206)
so, x2=3000,y2=206
now, we can find slope
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
now, we can plug values
![m=\frac{206-210}{3000-1000}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B206-210%7D%7B3000-1000%7D)
![m=-\frac{1}{500}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B500%7D)
now, we can use point slope form of line
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
so, we can plug it
![y-210=-\frac{1}{500}(x-1000)](https://tex.z-dn.net/?f=y-210%3D-%5Cfrac%7B1%7D%7B500%7D%28x-1000%29)
so, point slope form of line is
![y-210=-\frac{1}{500}(x-1000)](https://tex.z-dn.net/?f=y-210%3D-%5Cfrac%7B1%7D%7B500%7D%28x-1000%29)
now, we can plug x=8000
and then we can solve for y
![y-210=-\frac{1}{500}(8000-1000)](https://tex.z-dn.net/?f=y-210%3D-%5Cfrac%7B1%7D%7B500%7D%288000-1000%29)
![y=196](https://tex.z-dn.net/?f=y%3D196)
So,
the boiling point of water at an altitude of 8000 feet is 196°F..........Answer
Answer:10,800
Step-by-step explanation:
im not sure but what i did was 90x120=10800
Answer:
The answer is D. x= 4
Step-by-step explanation:
The angles are congruent so
2.3x +25 = 5.8x + 11
2.3x - 5.8x = 11 - 25
-3.5x = -14
x = 14/3.5
x = 4.
