Answer:
At the positive integer value of x=7 the quadratic function begin to exceed the linear function
Step-by-step explanation:
we have
using a graphing tool
see the attached figure
For x < -1.405 and x > 6.405 the quadratic function begin to exceed the linear function
so
At the positive integer value of x=7 the quadratic function begin to exceed the linear function
Step-by-step explanation:
200 divided by 5 equals 40.
So therefore, 40 times 5 equals 200.
Consider the equation
![-10x-y=-20](https://tex.z-dn.net/?f=-10x-y%3D-20)
1) First row of the table
Set x=0 and solve as follows:
![\begin{gathered} -10(0)-y=-20 \\ \Rightarrow-y=-20 \\ \Rightarrow y=20 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-10%280%29-y%3D-20%20%5C%5C%20%5CRightarrow-y%3D-20%20%5C%5C%20%5CRightarrow%20y%3D20%20%5Cend%7Bgathered%7D)
The answer is y=20 and the pair x-y is (0,20)
2) Second row
Set x=1 and solve, as follows:
![\begin{gathered} -10(1)-y=-20 \\ \Rightarrow-10-y=-20 \\ \Rightarrow-y=-10 \\ \Rightarrow y=10 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-10%281%29-y%3D-20%20%5C%5C%20%5CRightarrow-10-y%3D-20%20%5C%5C%20%5CRightarrow-y%3D-10%20%5C%5C%20%5CRightarrow%20y%3D10%20%5Cend%7Bgathered%7D)
The answers are y=10 and (1,10)
3) Third row.
Set y=0 and solve as follows:
![\begin{gathered} -10x-(0)=-20 \\ \Rightarrow-10x=-20 \\ \Rightarrow x=\frac{20}{10}=2 \\ \Rightarrow x=2 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-10x-%280%29%3D-20%20%5C%5C%20%5CRightarrow-10x%3D-20%20%5C%5C%20%5CRightarrow%20x%3D%5Cfrac%7B20%7D%7B10%7D%3D2%20%5C%5C%20%5CRightarrow%20x%3D2%20%5Cend%7Bgathered%7D)
The answers are x=2 and (2,0)
A
b
x−c=0
Step 1: Multiply both sides by b.
ax−bc=0
Step 2: Add bc to both sides.
ax−bc+bc=0+bc
ax=bc
Step 3: Divide both sides by x.
ax
x
=
bc
x
a=
bc
x
Answer:
a=
