Answer:
7/9 + (-7/9) = 0
Step-by-step explanation:
Definition of additive inverse:
Two numbers are additive inverses if their sum is zero.
For example, 2 and -2 are additive inverses since 2 + (-2) = 0.
Now your problem:
7/9 + (-7/9) =
7/9 and -7/9 are additive inverses.
Therefore, their sum is 0.
7/9 + (-7/9) = 0
where m is the slope of the line and b is the y-intercept. Hope that helps
I dont know the answer but i just need point for a question sorry
The answer will be B; this is because the cost of each notebook is equivalent to 1.6, or is less than or equal to $56 as we are currently unsure of the value of n (number of notebooks) which means it may cost exactly $56 or less than that as she only has $56 to buy the notebooks to donate to her school
Answer:
<h2>-6x + 7y = 11</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
m - slope
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (-3, -1) and (1/2, 2). Substitute:
![m=\dfrac{2-(-1)}{\frac{1}{2}-(-3)}=\dfrac{3}{3\frac{1}{2}}=\dfrac{3}{\frac{7}{2}}=3\cdot\dfrac{2}{7}=\dfrac{6}{7}\\\\y-(-1)=\dfrac{6}{7}(x-(-3))\\\\y+1=\dfrac{6}{7}(x+3)}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B2-%28-1%29%7D%7B%5Cfrac%7B1%7D%7B2%7D-%28-3%29%7D%3D%5Cdfrac%7B3%7D%7B3%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cdfrac%7B3%7D%7B%5Cfrac%7B7%7D%7B2%7D%7D%3D3%5Ccdot%5Cdfrac%7B2%7D%7B7%7D%3D%5Cdfrac%7B6%7D%7B7%7D%5C%5C%5C%5Cy-%28-1%29%3D%5Cdfrac%7B6%7D%7B7%7D%28x-%28-3%29%29%5C%5C%5C%5Cy%2B1%3D%5Cdfrac%7B6%7D%7B7%7D%28x%2B3%29%7D)
Convert to the standard form Ax + By = C:
<em>multiply both sides by 7</em>
<em>use the distributive property</em>
<em>subtract 7 from both sides</em>
<em>subtract 6x from both sides</em>
