Answer:
so b=-9 while c=12.
Step-by-step explanation:
If you have x-intercepts 1 and -4, then that means f(1)=0 and f(-4)=0.
You are given
So you have the system of equations to solve:
Evaluating the exponents:
Doing a little bit of multiplying:
Let's add 3 on both sides of equation 1 and 48 on both sides of equation 2:
Subtracting the equations will eliminate c.
Let's do that:
Divide both sides by 5:
Simplify:
If b=-9 and b+c=3 then -9+c=3 implies c=9+3=12.
so b=-9 while c=12.
Answer:
-7
Step-by-step explanation:
step 1,
put -3 into the function
step 2,
4(-3) + 5 = -7
It would be 6 because if it is .4 or below you round down and if it is .5 or above you round up
Answer:
4k
Step-by-step explanation:
The product means to multiply 4 and the variable k. Writing an algebraic expression to represent the product of 4 and k just means to translate "the product of 4 and k" into an algebraic expression.
The algebraic expression that represents the product of four and k is 4*k or 4k.
