Answer:
Step-by-step explanation:
- Option A
![[x+5=20]](https://tex.z-dn.net/?f=%5Bx%2B5%3D20%5D)
tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.
- Option B
![[x=5]](https://tex.z-dn.net/?f=%5Bx%3D5%5D)
tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too. - Option C
tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality. - Option D
![[x+5]](https://tex.z-dn.net/?f=%5Bx%2B5%5D)
is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
Answer:
I think its 4
Step-by-step explanation:
don't really know how to but its simple really
Answer:
f(x)=3x^2+2x-10 if x=2
f(x)=3(2)^2+2(2)-10
f(x)=3(4)+2(2)-10
f(x)=12+4-10
f(x)=16-10
f(x)=6
g(x)=3x-3 if g(x)=2
g(x)=3(2)-3
g(x)=6-3 =3
Step-by-step explanation:
<u>f</u><u>(</u><u>x</u><u>)</u>
- replace x by 2
- do exponent
- distribute the brackets
- do addition and subtraction
g(x)
- replace x by 2
- distribute the bracket
- do subtraction
