Answer:
$0.26
Step-by-step explanation:
To find the unit price, divide the cost by the amount you have.
$2.86/11 = $0.26
The unit price is $0.26.
Answer:
9
Step-by-step explanation:
Calculate the absolute difference of the 2 points, that is
| - 7 - 2 | = | - 9 | = 9 , or
| 2 - (- 7) | = | 2 + 7 | = | 9 | = 9
Answer:
105.4º
Step-by-step explanation:
supplementary angles total 180º
180 - 74.6 = 105.4º
Answer:
The equation of the line is:
![y=2x-1](https://tex.z-dn.net/?f=y%3D2x-1)
Step-by-step explanation:
Given the points
Finding the slope between the points
![\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cmathrm%7BSlope%7D%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![\left(x_1,\:y_1\right)=\left(-2,\:-5\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%28-2%2C%5C%3A-5%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%281%2C%5C%3A1%5Cright%29)
![m=\frac{1-\left(-5\right)}{1-\left(-2\right)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1-%5Cleft%28-5%5Cright%29%7D%7B1-%5Cleft%28-2%5Cright%29%7D)
![m=2](https://tex.z-dn.net/?f=m%3D2)
We know the slope-intercept form of the line equation
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where m is the slope and b is the slope-intercept form
substituting the value m=2 and the point (-2, -5) to find the b-intercept
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
-5 = 2(-2) + b
b = -5+4
b = -1
Now, substituting m=2 and b=-1 in the slope-intercept form to get the equation of a line
y=mx+b
y=2x+(-1)
y=2x-1
Thus, the equation of the line is:
![y=2x-1](https://tex.z-dn.net/?f=y%3D2x-1)
