We have the function and we want to find a function that has the same y-intercept than the previous function.
First, let's find the y-intercept by subtituting 0 for 'x'.
Now that we found that y-intercept =-3, any lineal function of the type: will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type: will have the same y-intercept. Where 'a' and 'b' can take all the real values.
21/7 = 3 so then, 105/7 = x which is 15
Answer:
40
Step-by-step explanation:
9a + 9b + 9c = 5
Multiply the equation by 8
8*(9a + 9b + 9c )= 5*8
Distribute
72a +72b +72 c = 40
Its simple, the expression is 7+x and it does not have an equal sign since it is not an equation
I'm pretty sure that 20 is 5 but other than that, I can't help with anymore.
