cause when we substitute 5 in the equation we get 3<7which is true.
I would say the x intercept is (6,0) and the y intercept is (4,0)
Answer:
Step-by-step explanation:
<u>Consider the parent function:</u>
The graph of the function open up and the vertex is at the origin, the point (0, 0)
Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:
The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:
<u>Since all the options have 1/20 as a coefficient, our function is:</u>
This is option B
Answer:
The plumbers cost would be equal to the equation 80+45x=y with y being the total amount of money he made and x being how many hours he worked.
Step-by-step explanation:
In this equation to find the amount the plumber was paid all you need to do is plug in the amount of hours he worked for x.
If the plumber worked his maximum of 8 hours then the equation would change from 80+45x=y to 80+(45×8)=440.
So, if the plumber worked for 8 hours he would make $440.
