Hello!
You can solve this algebraically
4(a - 5) = a + 1
Distribute the 4
4a - 20 = a + 1
Add 20 to both sides
4a = a + 21
Subtract a from both sides
3a = 21
Divide both sides by 3
a = 7
The answer is 7
Hope this helps!
Answer:
x-intercept is -1; y-intercept is 0.5.
Step-by-step explanation:
The x-intercept is relatively easy to read off. It's the x-value where the graph crosses the x-axis, and here is (-1,0).
The y-intercept is best estimated as (0,+0.5).
The correct answer is the 3rd one on the list.
Answer:
See explanation below
Step-by-step explanation:
In order to get rid of the denominators in the equation:
![\frac{1}{5} x+8=\frac{1}{10} +9](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B5%7D%20x%2B8%3D%5Cfrac%7B1%7D%7B10%7D%20%2B9)
We find the Least Common Denominator for both denominators (5, 10) which is 10, and multiply BOTH sides of the equal sign by 10 as shown below (notice that the factor 10 we introduce multiplies ALL terms inside the parentheses):
![10*(\frac{1}{5} x+8)=10*(\frac{1}{10} +9)\\\frac{10}{5} x+80=\frac{10}{10} +90\\2x+80=1+90\\2x=91-80\\2x=11\\x=11/2](https://tex.z-dn.net/?f=10%2A%28%5Cfrac%7B1%7D%7B5%7D%20x%2B8%29%3D10%2A%28%5Cfrac%7B1%7D%7B10%7D%20%2B9%29%5C%5C%5Cfrac%7B10%7D%7B5%7D%20x%2B80%3D%5Cfrac%7B10%7D%7B10%7D%20%2B90%5C%5C2x%2B80%3D1%2B90%5C%5C2x%3D91-80%5C%5C2x%3D11%5C%5Cx%3D11%2F2)
