Answer:
y = 2.5x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2.5 and c = - 8 , then
y = 2.5x - 8 ← equation of line
Answer:
8
Step-by-step explanation:
3 times 3 is 9
2 yimes 5 is 10

Answer: ![\$16\dfrac{9}{10}](https://tex.z-dn.net/?f=%5C%2416%5Cdfrac%7B9%7D%7B10%7D)
Step-by-step explanation:
Given
Hannah had 30 dollars
Money spent on gift A
![8\ \dfrac{7}{10}=\dfrac{8\times 10+7}{10}=\dfrac{87}{10}](https://tex.z-dn.net/?f=8%5C%20%5Cdfrac%7B7%7D%7B10%7D%3D%5Cdfrac%7B8%5Ctimes%2010%2B7%7D%7B10%7D%3D%5Cdfrac%7B87%7D%7B10%7D)
money spent on gift B
![4\ \dfrac{2}{5}=\dfrac{22}{5}](https://tex.z-dn.net/?f=4%5C%20%5Cdfrac%7B2%7D%7B5%7D%3D%5Cdfrac%7B22%7D%7B5%7D)
Money spent on gift C
![\Rightarrow \text{Total-Money spent on (A+B)}\\\\\Rightarrow 30-\dfrac{87}{10}-\dfrac{22}{5}=30-\dfrac{87}{10}-\dfrac{44}{10}\\\\\Rightarrow \dfrac{300-87-44}{10}=\dfrac{169}{10}\\\\\Rightarrow \$16\ \dfrac{9}{10}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctext%7BTotal-Money%20spent%20on%20%28A%2BB%29%7D%5C%5C%5C%5C%5CRightarrow%2030-%5Cdfrac%7B87%7D%7B10%7D-%5Cdfrac%7B22%7D%7B5%7D%3D30-%5Cdfrac%7B87%7D%7B10%7D-%5Cdfrac%7B44%7D%7B10%7D%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7B300-87-44%7D%7B10%7D%3D%5Cdfrac%7B169%7D%7B10%7D%5C%5C%5C%5C%5CRightarrow%20%5C%2416%5C%20%5Cdfrac%7B9%7D%7B10%7D)
